[sdiy] MIDIBass-303 MIDI data format

[Richie Burnett]

Season's greetings to all !

Does anyone here use a Roland TB-303 with Colin Fraser's MIDIBass interface
fitted?

http://www.colinfraser.com/mb303/

In particular I am interested in the detail of the MIDI data stream that is
produced when the 303's internal sequencer is playing.  The website provides
lots of details about SysEx exchanges and an example of the audio.  However
it doesn't include any example MIDI files produced using the interface, or
say how note slides from the internal sequencer are transmitted over MIDI.

I'm not trying to copy the MIDIBass product, moreover I am developing a
product that I would like to be compatible with the MIDIBass interface's
protocol as well as x0xb0x and AudioRealism ABL products.

In particular I am interested to know if slides are signalled via multiple
overlapping notes, or if they are signalled using the standard MIDI
controllers for legato or portamento.

Thanks in advance for any help,
