[sdiy] MIDI to CV question - no Triggers?

[Carsten Tönsmann]

Hi Dave,

as I know devices with trigger input really nead a complete pulse cycle to 
react. So if you use it with a gate, the envelope might restart after 
_release_ of the second key, not after _pressing_ it. I would build a simple 
monoflop to get a trigger pulse from a gate out. That should make your 
device work.

Polyphonic MIDI2CV converter should have a gate out for every parallel note 
event, so a 4 channel device should have 4 gate outputs. See also
