atmega_midi_cv_basic

Simple gate+pitch+velocity with one 4822

Portamento time is controlled by MIDI CC #5.

When more than one MIDI note is active, the frequency CV is set according to the value of MIDI CC #80 as follows:

CC #80 Note Priority
0-31 Lowest Note
32-63 Highest Note
64-127 Highest Velocity (default)

The MIDI channel can be set by sending the following SYSEX message: 0x77 0x16 0x01 0x00 0xcc where cc is the new channel.
