Adagio in Transcribe Mode


The Transcribe mode of Adagio is used to record performances via MIDI and to translate them into Adagio score files. Rather than attempt to guess musical durations (like a dotted-quarter), Transcribe records all times and durations in milliseconds. This mode, together with Record, makes it fairly simple to build up complex Adagio scores one part at a time. Transcribed music can be copied, edited, or repeated using an ordinary text editor. The output from Transcribe might also be useful in the study or evaluation of performances.


To use Transcribe mode, start up Adagio as before (see page ``Running Adagio'') and type "t RETURN" to select Transcribe mode. You will then get the following prompt:
TRANSCRIBE MODE:  type <return> to transcribe, ? for help,
 q to quit :
Type RETURN and you will be prompted for a file name for the score you will create:
output file :
Type a file name. If the file already exists you will be asked whether you really want to overwrite the file with new data. If you do not provide an extension, .gio will be appended to your file name automatically. Next, Transcribe will ask you if you want to record continuous controller data. The default (no) will produce shorter files but will filter out information such as pitch bend, volume control, modulation wheel and aftertouch:
Enable recording of pitch bend, etc.? [n]
Type y, n, or just RETURN for the default n. Generally, you should type RETURN. When you have finished what you want to play, type the space bar. This signals the program to stop and write out the notes. This file can now be played (in Play mode) and what comes out will be very similar to what you just heard yourself play.


MIDI has the problem that a computer cannot inquire the current program selections. Thus if a synthesizer is set to program 23 and a passage is recorded by Transcribe, the resulting file will not contain a Z23 command, and there is no guarantee that the synthesizer will be set to program 23 when the file is played in the future. The best solution is to press program 23 on the keyboard before playing any notes. This will send a program change command that will be recorded into the file and replayed later.

Transcribe and Record modes record Z attributes whenever they receive a MIDI Program Change command. Synthesizers normally send this when you change a preset sound using the controls on the synthesizer. One notable exception is that if a Yamaha synthesizer is in the ``Sys Info Avail'' mode, then pressing a button to change the program causes the synthesizer to dump all of the internal data comprising the program. No MIDI Program Change command is sent, so Transcribe records nothing. You can find out what is happening by running the MM (Midi Monitor) program and pushing a program change button on your synthesizer. For Yamaha synthesizers, the mode should be ``Sys Info Unavail'', which is a fairly cryptic way to say ``send program numbers instead of program data''.
