Is it normal behaviour that bus CV outputs the voltage of the last played note even when a note off was received? I would expect it to output 0 volt after the noteoff.

When I implemented the code for the "Bluetooth MIDI to CV (ESP32)" module I asked myself the same question: should I set the output to 0 volt when I get a noteoff? I decided to leave the output voltage and just set the trigger output to 0 volt (same as the Master module) for the following reason. My understanding: 0 volt for the control voltage of the pitch does not mean that the note is off. It means that you add nothing (0 volt) to the base frequency of the oscillator. To turn the note on and off you use the gate output to control the envelope. So for me it makes sense that the Master module behaves like this. |

I just checked that this is also the behavior of my Arturia Keystep: When I press a key, the output voltage changes to the respective value. The value changes when I press a different key (of course).
But the output voltage stays at the last value even when I release the key.

yep same here, quite annoying imho since I wanted to be able to do keyboard splits on my aemodular based of the note voltage, which should be a breeze with the 4COMP module but alas a sticky last note voltage messed this plan up.

Could you use the 3VCSwitch and use the note off to stop the CV getting to the oscillator?... |

Unfortunately I don't think the note off is available as a signal on the master module or the bus but I can try something via the envelope end triggers to toggle a switch of some kind. I don't have the 3CVswitch module but I can use my switchmatrix to do some switching, I really have to start putting more mileage into that module.  |

The bus gate out on the master will go to 0V when key off, maybe that one could be wrangled? |

I would expect the cv to stay the same after a note-off, main reason being that there might be some ‘release’ stage on a note, and you would therefore want the tail of a note to be at the same pitch as the sustain part…
(I’m assuming that bus-gate goes high/low with note on/off respectively of course — it’s been a while since I played with it)

Solution is tested and works like a charm. Now i can sequence multiple voices separately over the same midi channel.
