5 poly notes from a keyboard

Playing an external keyboard with MIDI-CV as the interface I can only get notes from 5 keys at a time, whatever settings I use for Polyphonic Channels or Polyphony Mode.

I’ve tried other MIDI interface modules (MTS-ESP from OddSound, MIDI Poly+MPE from moDllz) and get the same result. Is this a MIDI thing? It’s not a problem - if that’s the way it is then ok but would like to know. Forgive my ignorance.

I have no problems with (in this case) 8 notes I played all notes of the c major scale starting at c3-c4 and they all played as seen here :

Are you using your typing keyboard as a keyboard ?

Yes - could that be the difference?

I think there is a limit to the number of keys you can press simultaneously on a typing keyboard.

Not what I was looking for, but maybe somebody else knows.

A crappy 2 octave USB keyboard would be such an improvement, esp if it has a bunch of knobs on it. If you can find someone who is giving one away… or find one for sale super cheap…

Totally correct. Most cheap and laptop computer keyboards have 2 KRO (key roll over), USB keyboards have a protocol limit of 6 KRO.

Logitech states that the G413 has a “26-key rollover” - that’s the keyboard i use.
