Re: More on MIDI handler

2004-04-09 by grantrichter2001

My primary interest if to store high resolution data on a MIDI 
recorder. Pitch bend is a 14 bit data type. If you store 4 channels 
of pitch bend data, and can decode 4 channels of pitch bend 
data, you have a high resolution 4 channel control voltage 
recorder which can be edited graphically with unlimited lenght 
sequences.

Could be useful...
