[sdiy] MIDI bass pedals update

[phillip m gallo]

Portamento is that which distinguishes a synth from an organ with my limited
world view.

My Jx3P which incorporates an analog backend for DCO's does not incorporate
"glide" as it would require some sexy programming of the timer and master Fz
switching, so it's just a fancy organ.  When i implemented the YM2203C DCO's
i had to implement the equiv. kind of programming to ensure it could honor
portamento MIDI activations so it is do-able.

regards,
p

When I first got into MIDI I already knew that MIDI messages supported
portamento, but I couldn't find a synth that supported it either.  I
have 3 sound modules (Roland) and a Korg WaveStation and none support
it.  I wrote a MIDI message processor program that creates the
portamento effect by calculating and sending a stream of MIDI pitch
wheel messages, but that's a completely different way of doing it and it
uses a lot of MIDI bandwidth.  It works very well as a performance tool,
but doesn't do well in a sequenced environment.  That's when I started
looking at analog synths that are MIDI capable.
