Hi,
here are my answers to Sequencer questions, some of my answers may be a little short as i had some difficulty finding suitable sources of information. 
01-What is a MIDI sequencer?
A MIDI sequencer is a device that records MIDI data to enable the playback, storage and edit of that data. A sequencer records everything that goes into making the sound but not the sound itself ie. pitch, tone, duration etc. The sequencer records speed with which each key was struck, the length of time the keys were held. In other words, the sequencer records the performance information and then on playback instructs a MIDI-equipped instrument to reproduce the sound.
02-What are the advantages of hardware sequencers?
The advantages of hardware sequencers are that they are portable, compared to a software sequencer, which is based on a PC. The price is another advantage compared to a software sequencer, which will require the purchase of a PC as well as the software itself.
03-What are the advantages of software sequencers?
The advantages of a software sequencer are the number of features available and the user interface. A software sequencer takes advantage of a PC’s monitor to give a superior graphical display and user-friendly interface compared to the small screen of a hardware sequencer. A software sequencer can be the cheapest option if you already have a PC, as the software itself is reasonably priced.
04-What is a piano roll editor?
A piano roll editor allows MIDI notes that have been recorded, to be edited for any mistakes in note length or spaceing. It is a visual interpretation of what has been keyed by the MIDI device. The piano notes are set out vertically to the left of the editor, with the note length being displayed by horizontal blocks.
05-What is a 'drum map'?
A drum map is a key to instrument mapping system that appears on MIDI channel 10. It tells the user what key corresponds to which drum instrument ie C4 - Hi Mid Tom, D3 - Acoustic Snare.
06-What is usually seen in the 'arrange' window?
The arrangement of tracks and any automation is usually seen in the 'arrange' window. As the sequence is played the window will scroll from left to right playing the notes. Editing may take place in the 'arrange' window.
07-What are Tempo/Meter maps?
A tempo map holds information about the tempo of the song. If there are tempo changes during the duration of the song they will be recorded in the Tempo map.
08-What is the purpose of quantizing?
Quantisization refers to the accuracy of the timing of notes in relation to the track. The purpose of quantisizing is to change the note structure so it is more in time with the rest of the track. In a MIDI sequencer notes can be quantisized to a very accurate level.
09-What is Groove Quantizing and how does it work?
Groove quantisizing is used to change the note structure so it is in sync with a particular type of music. It is used to create a rythmic, or live feel to the notes that sits well within the genre.
10-Explain Note On quantizing.
Note On quantisization moves the notes to the nearest quantisize value and does not alter the length of the notes.
11-Explain Over Quantizing.
Over Quantisizing is what happens if notes are 'perfectly' quantisized. The beginning and the end of the note are moved in time with the music, unlike note on quantisizing which does not alter note length. This gives an unrealistic sound to the notes, as if they are robotic.
12-Explain Iterative Quantizing.
Iterative quantisizing enables notes to be moved closer to quantisize values depending on a selected value. It is done in stages where particular notes can be excluded from the quantisize process, which gives a more human feel to the note spacing. The more stages are completed the closer the notes will get to the desired quantisize level.
13-What do quantize values such as 4,32,16T etc represent?
The quantisize value 4 represents a quarter note, 32 represents a 32nd note and 16T represents a 16 note triplet. Triplets work on the basis of 3 for every 2 divisions. Straight 16th notes are 8 sets of 2, so 16th triplets are 8 sets of 3.
14-What is the score editor and how does it display musical information?
A score editor displays musical information as notes on a traditional score sheet. It allows notes to be drawn or edited in a traditional manner and then printed off to be used by musicians.
15-How, and using what protocol, may a Sequencer be synchronised to a multitrack recorder?
A MIDI sequencer may be synchronised to a multitrack recorder using such protocols as MIDI Timecode (MTC), SMPTE/EBU Timecode, Frequency Shift Keying (FSK) or MIDI Clock. MTC and SMPTE timecodes would be the preferred option as they measure 'real' time in hours, minutes, seconds. This can be achieved by connecting the sequencer to a MIDI tape sync unit, which can convert SMPTE code to MTC. It works by using one track of your multi-track tape machine to carry the synchronisation information (sync tone). When a sync tone is recorded on a tape track it is called a stripe. The format of the stripe is related to the corresponding MIDI synchronisation datastream.
16-If you change the tempo of the song, what will happen to (a) the MIDI parts? (b) the Audio parts?
If you change the tempo of the song the following will happen: a) The MIDI parts of the song will be in sync with the tempo, therefore if it increases, the MIDI parts will increase. b) The audio parts will not be in sync with the tempo. They will be played at their original tempo and therefore sound out of time.
17-How does the application Recycle allow MIDI to control Audio parts?
From propellorhead: When using a sampler, Recycle will download the slices to the target sampler as individual samples, while generating a MIDI file based on the original rhythm of the audio file. This MIDI file is then obviously free to be manipulated using all the MIDI tools available within the sequencer application.
I'm not quite sure what that means. I think it means that individual samples are created that can then be controlled by MIDI.
18-What is OMS?
Open Music System (OMS) was created by Opcode. It provides the means to manage MIDIs by using an on-screen setup to display and edit MIDIs. OMS allows compatible MIDI programs to interact with computer hardware ie soundcards.
19-How does OMS simplify MIDI studio setups?
OMS uses an on-screen display which shows connections to MIDI interfaces, sound cards and instruments, which simplifies the studio setup. It's features include factory names for over 100 devices, and the convenience of being set up once for all MIDI applications.
20-What's the difference between type 0 & 1 MIDI sequences?
Type 0 has only one track, which can contain messages for multiple MIDI channels as well as the tempo data. Type 1 allows multiple tracks, which can be played simultaneously. Type 0 may be smaller, and therefore conserve storage space. They may also be transferred using slightly less system bandwidth than type 1 files. However, type 1 files may be viewed and edited more directly, and are therefore generally preferred.
21-Why are there 'virtual' MIDI ports available (i.e. Hubis Loopback)?
Virtual MIDI ports are used when there is no MIDI interface included with the chosen software. They create a link via MIDI.
22-What is the 'rewire' protocol?
Definitions: The ReWire protocol is a software interface between sequencer and audio applications. Through ReWire, a host application can use a client application as an external instrument. ReWire is a system invented by Propellerhead for routing up to 256 MIDI channels between ReWire aware applications.
Basically, a means of transferring data between a sequencer and different types of audio software.
23-What is the rocket networks protocol and how does it work?
The rocket networks protocol allows musicians to exchange and collaborate on projects across the world. It enables users to communicate with each other via the internet through a collaboration of recording studios. It enables songs to be mixed remotely from anywhere in the world.
24-What are step sequencers?
Step sequencers record one note at a time in exact steps (16th notes,8th notes,etc). This can be useful for programming a passage of notes faster than is possible to play them. Drum machines generally come with a built in step sequencer for creating drum loops.
25-Why are step sequencers usually more suitable for percussion & drum parts?
Step sequencers are usually more suitable for percussion & drum parts as they are based around the same principles as the sequencer. Percussion and drum parts are usually looped and follow a step pattern.
26-Why are click tracks important functions in MIDI/Audio sequencers?
A click track provides an audible metronome that follows the changes in time signatures. It is important in MIDI/audio sequencers as it helps a musician playing an instrument to play in sync with the sequencer.
27-Why do many sequencers metronomes allow either Audio or MIDI clicks?
Many sequencers metronomes allow either Audio or MIDI clicks, which gives the user a choice as to the sound of the metronome they wish to hear. If you do not wish to hear MIDI clicks, an alternative sound may be used.
28-How is MIDI data such as modulation and pan usually displayed in part editors?
MIDI data such as modulation and pan are control change messages. They have a numerical range of 128 program numbers. They are displayed as a value between 0 and 127.
29-How many times is master clock transmitted per quarter note?
Master Clock(or Timing clock) is a System Real Time message that sets the tempo for playback of a sequence. The Master Clock message is sent 24 times per quarter note.
30-What are the functions of the master and slave in any synchronisation situation?
The function of the master in a synchronisation situation is to send messages to slaves ie. start, stop. The slave's function in a synchronisation situation is to follow the master.
31-What timing division does SPP (song position pointers) work on?
SPP (song position pointers) work on 16th of a note time division.
32-What is MIDI Sync mode and what synchronisation protocols does it accept?
MIDI Sync mode is used when synchronising MIDI equipment such as a sequencer with drum machines or other MIDI sound modules. It accepts the following protocols: MIDI TimeCode(MTC), MIDI Clock.
33-What is the primary difference between MIDI Time Code and MIDI Clock, and why is MTC more accurate?
The primary difference between MIDI TimeCode and MIDI Clock is that MIDI TimeCode records song positions in hours, minutes, seconds and frames. Whereas MIDI Clock data is a series of electronic timing markers that are related to the beats per minute of the signal. MIDITime Code has a higher resolution that MIDI Clock data and gives the ability to find a song position in real time. MIDI Clock data is used to synchronise equipment only.
34-Define the basics of SMPTE?
Society of Motion Picture and Television Engineers(SMPTE) is based on a continuously running eight-digit clock registering time in hours, minutes and seconds and frames. There are 2 types of SMPTE, VITC(Vertical Interval TimeCode) and LTC(Longitudinal Timecode. VITC is used in synchronising audio to video. LTC is used in audio recording and can be recorded onto magnetic tape. SMPTE runs at 30 frames per second. Each timecode frame is represented by an 80 bit binary message split into 4 bits. Each bit represents a particular parameter such as tens of hours, units of hours etc.
35-What similiarities are there between SMPTE and MTC?
MIDI TimeCode is a MIDI interpretation of the traditional Longitudinal TimeCode(LTC) SMPTE (Society of Motion Picture and Television Engineers) protocol. MIDI TimeCode is a way of transferring longitudinal timecode around a MIDI system. Longitudinal TimeCode is a different format to MIDI messaging, therefore the signal must be converted into a MIDI compatible format ie. status byte followed by data bytes.
36-How does FSK work?
Frequency Shift Keying(FSK) is a system which records a series of electronic tones. FSK is a variable rate based upon tempo, so no interpolation is needed by the sequencer and therefore tracks tempo changes the best of any sync protocols. Unlike MIDI Clock data, FSK can be recorded to analog tape.
37-Does standard-FSK synchronisation give any indication of song position?
Standard FSK synchronisation does not allow a song to be started in the middle and have the sequencer immediately advance to that section of the performance in sync.
38-What improvements does Smart-FSK offer over standard FSK?
Smart FSK allows a song to be started in the middle and have the sequencer immediately advance to that section of the performance in sync.
39-If using FSK with analogue tape, why must the speed of the tape not change after recording the FSK timing information?
FSK records a series of tones that are used to synchronise equipment. If the speed of the tape is increased it will disrupt, or speed up the timing information.
40-What is the 'tempo master' and what is the 'transport master' within a MIDI synchronised setup?
The tempo master controls messages to devices that relate to the increase/decrease of the tempo. The transport master controls messages to devices that relate to performance ie. start, stop messages.
41-What problems may arise from extensive use of controller data within a MIDI piece?
Extensive use of controller data within a MIDI piece will take up a lot of the bandwidth, which will have an adverse affect on timing information and therefore performance. When large amounts of midi data need to be output simultaneously then you may get what's referred to as Midi Data Clogging. All of those events must be output one at a time, because MIDI is a serial transmission.
42-Name 2 different connection protocols for MIDI interfaces?
2 different connection protocols for MIDI are the standard 5-pin DIN MIDI connector and SCSI (Small Computer System Interface).
43-Can tempo changes and time signature changes be made during a song within a sequencer?
Yes, tempo changes and time signature changes can be made during a song within a sequencer. This information is then controlled by the tempo master.
44-What considerations must be made when using a software sequencer as part of a live show?
The following considerations should be made when using a software sequencer as part of a live show: There must be a backup device present in case of the failure of the chosen software sequencer. |

Hi Ben sorry for delay
01-What is a MIDI sequencer?
A midi sequencer is a device (hardware or software) that can: record, edit, store and playback digital data representing a musical performance.
02-What are the advantages of hardware sequencers?
Hardware sequencers are stand-alone devices designed to perform the tasks outlined above. Hardware sequencers are ROM based devices which offer a level of stability superior to PC based sequencers. Hardware sequencers also exhibit no latency. Additionally hardware sequencers are portable and relatively cheap (when compared to the price of a computer, MIDI interface, and software). Hardware sequencers are physically quieter than pc based software sequencers.
03-What are the advantages of software sequencers?
Graphical computer monitors ease of use.
Large range of third party utilities (software effects etc).
Ability to record and replay audio.
Choice of software available and the ability to change this.
Most hardware sequencers only offer one or two midi outputs, whilst software sequencers provide six or more offering 96 Midi channels.
Software sequencers offer the ability to export midi/audio files for use on other systems and sometimes other software.
Midi files can be imported to almost any system.
04-What is a piano roll editor?
A piano roll editor (often the default midi editor in software sequencers) represents midi notes graphically in an intuitive piano roll-style grid. Sometimes called the key editor it can display two or more editors together with editing of notes and/or one or more controllers. This editor is commonly used for midi musical and performance (controller) editing.
05-What is a 'drum map'?
The drum map or editor is similar to the piano roll editor but takes advantage of the fact that with drum parts, each key usually represents a separate drum sound (sample). With the drum editor the pitch of a sound is usually shown as a drum name (snare, kick etc) rather than the note numbers displayed in the piano roll or “key” editor.
06-What is usually seen in the 'arrange' window?
Nuendo
All recorded tracks (audio, midi, groups, folder, marker, automation and effects).
Transport and all it’s settings.
The Mixer.
The Pool.
Timeline.
Event and track information.
The Inspector.
07-What are Tempo/Meter maps?
Tempo maps are a graphical representation of tempo on an x/y axis where the x axis represents tempo and the y axis position along the timeline.
08-What is the purpose of quantizing?
Quantizing in its fundamental form is a function that automatically moves recorded notes, positioning them on exact note values. It can be used to “tidy” up recorded midi parts and it can also be used creatively to add “swing” to a recorded drum part.
09-What is Groove Quantizing and how does it work?
Groove quantizing differs from corrective quantizing in a number of ways, firstly the positions to which the groove quantize is set need not be exactly on a division of the beat. Groove quantizing actively seeks out timing irregularities which other types of quantizing seek to eradicate. By defining a new set of divisions, sometimes over the space of a number of bars, groove quantizing attempts to re-create some of the characteristics of a “real” musical performance, where notes don’t fall exactly on the beat.
Some groove quantizing functions also allow users to set individual velocity-scaling and/or note duration scaling values for each division. These functions add to the “natural” feel of midi performances providing variations in dynamics and note lengths.
10-Explain Note On quantizing.
Note on quantizing is the most basic quantize approach. In this type of quantizing notes are moved to the nearest quantize value.
11-Explain Over Quantizing.
This type of quantizing moves notes but also attempts to detect chords and keeps these notes together..
12-Explain Iterative Quantizing.
Iterative Quantizing moves notes a certain amount “toward” the closest quantize value. How much these notes are moved is set by the user. With this form of quantisation it is possible to move notes toward the quantize value in stages until the desired feel is achieved.
13-What do quantize values such as 4,32,16T etc represent?
Quantizing values represent the division of a bar to which the notes will be quantized. In these cases, a ¼, 32nd and 16th triplet note values respectively.
14-What is the score editor and how does it display musical information?
The score editor is a midi editor which displays notes in the form of a musical score (manuscript)
.
15-How, and using what protocol, may a Sequencer be synchronised to a multitrack recorder?
Synchronising a sequencer to multitrack analogue tape will require “striping” the tape (usually the highest track number) with timecode (SMPTE) and converting this to Midi Time Code using a midi converter.
16-If you change the tempo of the song, what will happen to (a) the MIDI parts? (b) the Audio parts?
All midi parts will automatically lock to the new tempo, whilst audio parts will not respond and continue to playback at their own tempo.
17-How does the application Recycle allow MIDI to control Audio parts?
Recycle examines audio files for significant peaks in the sound, automatically calculates where appropriate edit points might be within the file and places markers at these points (it also allows the user to edit these for increased accuracy). Once the user is happy with these edit points the file can then export a standard midi file, to instruct a sequencer how and in what order to play each of these sampled “slices”.
18-What is OMS?
OMS was originally a system expansion for Mac OS that allows MIDI devices and Apple computers to communicate. OMS is a software package allowing users to control midi devices from a computer.
19-How does OMS simplify MIDI studio setups?
All midi devices within a system can be viewed edited and controlled from the software.
20-What's the difference between type 0 & 1 MIDI sequences?
A type 0 midi file has one track containing all of the midi events for an entire sequence, including title, time signature, tempo and music event. A type 1 midi file should have two or more tracks. The first contains information such as, title, time signature and tempo, the second and subsequent contain title, musical event data.
21-Why are there 'virtual' MIDI ports available (i.e. Hubis Loopback)?
Hubis loopback is a midi driver that adds virtual midi ports (up to 4) to a system. These virtual midi ports act as both input and output midi devices. This enables the sharing of existing midi ports with multiple programmes simultaneously. All midi data sent to the output is sent to all programmes at the input side.
22-What is the 'rewire' protocol?
Re-wire and re-wire 2 are protocols for streaming audio between two computer applications.
23-What is the rocket networks protocol and how does it work?
Rocket protocol was developed by steinberg and launched along with CubaseVST5. It is a real-time internet studio network based on rocket network’s internet technology to enable cubase users to meet in private or public studios for online collaboration.
24-What are step sequencers?
Step sequencers are devices, which allow the user to input data, notes, note values and other parameters one step at a time, directly into the sequencer.
25-Why are step sequencers usually more suitable for percussion & drum parts?
As drum and percussion parts are usually made up of a limited number of sounds arranged in bars and repeated over many bars step sequencers are a useful means of “programming” these drum parts. Also using step sequencers drum parts can be built up over a series of “passes” adding the different elements (kick, snare, hats etc.) until the desired part is completed.
26-Why are click tracks important functions in MIDI/Audio sequencers?
Click tracks enable different parts to be recorded into a midi/audio sequencer with the correct timing.
27-Why do many sequencers metronomes allow either Audio or MIDI clicks?
Some people prefer to record taking their timing from sounds other than midi clicks. Many sequencer metronomes allow users to substitute these harsh midi clicks for other sounds (kick, hi hats etc.).
28-How is MIDI data such as modulation and pan usually displayed in part editors?
Graphically
29-How many times is master clock transmitted per quarter note?
24 times per ¼ note.
30-What are the functions of the master and slave in any synchronisation situation?
In any midi system (synchronisation of one or more device) there can only be one source of the clock event (the master). The master is the source of the clock and the slave(s) will be synchronised to it. This clock controls the tempo and start and stop functions.
31-What timing division does SPP (song position pointers) work on?
Song position pointers are messages indicating a location within a MIDI sequence. The pointer number value contains the number of sixteenths since the start of the sequence. Using this devices can lock almost simultaneously to the correct bar and beat of the sequence.
32-What is MIDI Sync mode and what synchronisation protocols does it accept?
Midi sync mode (or external sync mode) enables midi devices to take their timing references (slave to) from external compatible devices. Midi sync mode can accept Midi Clock, Midi time code or FSK (frequency shift key) protocols.
33-What is the primary difference between MIDI Time Code and MIDI Clock, and why is MTC more accurate?
MIDI timecode uses absolute time in its messages (hours, minutes, frames and sub frames), unlike MIDI clock, which tracks the time of a sequence in beats and measures. Midi time code is absolute, it uses a real time number to represent the exact location of a sequence (song) at an exact time. Midi clock on the other hand does not represent exact locations in a sequence, it represents very close estimations making it slightly less accurate than midi timecode.
34-Define the basics of SMPTE?
SMPTE (pronounced “simptee”) is not related directly to midi at all but is a real time code system based on elapsed time rather than on bars and beats, that is, it is related to absolute time rather than tempo. SMPTE was developed for the film and TV industries and comes in a variety of film and video frame rates. SMPTE is expressed in hours, minutes, seconds and frames.
35-What similarities are there between SMPTE and MTC?
Midi time code, like smpte, is independent of tempo and expresses elapsed time in hours, minutes, seconds and frames. As a result MTC can be easily translated into SMPTE enabling synchronisation with other non MIDI devices such as audio and video tape machines. In order to synchronise at the appropriate rate different frame rates can be selected:
24fps (frames per second) used in film.
25fps used for audio, video (PAL formats).
29.97fps NTSC formats.
30fps Monochrome television (US).
36-How does FSK work?
FSK or frequency shift key is a tempo related sync signal and gives no indication of location (song position). As a result it can only be used in conjunction with midi clock signals. When linked to a midi clock signal through a converter box it responds by producing an alternating “tone” (of 1.5Khz and 2.5Khz for every clock pulse). This tone is recorded to tape, which during playback is converted back into midi clock to keep the sequencer in sync. The sequencer being the slave.
37-Does standard-FSK synchronisation give any indication of song position?
FSK or frequency shift key is a tempo related sync signal and gives no indication of location (song position). As a result it can only be used in conjunction with midi clock signals.
38-What improvements does Smart-FSK offer over standard FSK?
Smart FSK is almost identical to FSK but can indicate a specific position within a sequence (song) based on 1/16 notes (song position pointer) and can therefore be used with midi sync. It is still recorded and played back in the same way as FSK but the converter must be instructed to produce smart FSK rather than FSK.
39-If using FSK with analogue tape, why must the speed of the tape not change after recording the FSK timing information?
The converter used with FSK can only respond to tones of 1.5 and 2.5KHz, changing the speed of the tape will change the pitch of these tones making it impossible to alter the tape speed after the FSK tones have been recorded.
40-What is the 'tempo master' and what is the 'transport master' within a MIDI synchronised setup?
The tempo master is used to create a tempo map (list of events which alter tempo at specific points) using a keyboard in step time.
The transport master is a device which sends Midi Machine Control messages such as play, stop and locate.
41-What problems may arise from extensive use of controller data within a MIDI piece?
As midi is a serial system extensive use of controller data can result in Midi “choke” where data does not reach its desired destination. This can cause devices to simply not respond or not respond to note off messages.
42-Name 2 different connection protocols for MIDI interfaces?
Midi Cables (5 pin DIN)
Amphenol connector (3 pin)
43-Can tempo changes and time signature changes be made during a song within a sequencer?
Yes.
44-What considerations must be made when using a software sequencer as part of a live show?
Everything which can go wrong will.
Things which cannot go wrong can always try.
Computers are not designed for the rigours of stage work (heat, vibrations, dust, liquid spillages, stumbling singers)
Take a backup system.
Uninterrupable power supply.
Allow for loading time between songs. |
