I'm not trying to 'sell' MIDI. I typically only use it for a
modularized Sound Canvas. You can get interesting sounds by modifying
the program change, not necessarily the notes. There are a couple of
samples on my page:
http://modularsynthesis.com/samples/samples.htmCircus, Nightmare, and Storm are examples. In one of these it's
basically the same note with a different program change.
Here's my point for MIDI. Consider it to be a simple serial
communciations for expansion. The programming overhead is nil and
there is lots of flexibility.
You need more D/A's? Connect it to a PAiA MIDI2CV. Eight more 7 bit
DAC's instantly available. In running status mode, it only takes 2
bytes for each DAC. You can send an update to all 8 DACs in less than
200 uS of program execution time. The actual serial transmission
will take ~5 mS. Don't think 7 bits is enough? Consider them digital
outputs. I have one program that drives twelve digital and one analog
outputs.
Have two ComputerVoltageSources? MIDI sysex would allow expansion and
intermodule communication. Want to control some external SDI devices?
A $3 Atmel processor can easily convert MIDI sysex messages to SPI.
How about some external relays? My favorite is vactrols to interface
external signal processors. I have a neat Ibanez digital delay that
is only ~4 vactrols away from being interfaced to my PSIM. I can
daisy chain my two displays together via MIDI sysex to have a 2x20 and
a 2x8 display simultaneous. Delays do add up but are in the order of
~1 mS.
Consider the possibilities of MIDI as a future expandability
mechanism.
