Vocoder MIDI notes sticking until none are playing

Hello! I recently upgraded to Cubase 13 (from 8) and have been having a lot of fun using the Vocoder to produce robotic vocals for my next video game with robot characters in bands.

One thing I don’t understand, and assume there is a setting for, is that by default a vocoder plugin has the behaviour where if a note starts playing, then another note plays afterwards with no gap, the first note will CONTINUE playing, creating an unintended chord effect.

This sometimes sounds cool, but it can be awkward to work around (by creating a tiny gap between the MIDI notes). What can I change to make it so ONLY the note that is currently playing in the MIDI route is the one that is utilised by the vocoder? Thanks.

Example: In my MIDI setup only one note is ever written to play at the same time, whereas in the audio playback it quite clearly is creating unintended chords.

I can’t upload a snippet of audio because it won’t allow links unfortunately.

I understand your post completely and have had the same issue. Unfortunately, my solution was the same as yours! A lot of experimentation with gaps between notes, which sometimes causes artifacts as the sound drops out during the gap.

In my last session I kind of gave up and used the TAL Vocoder instead, which is free.

good to hear that i am not the only one facing that issue. I was really looking forward to the stock vocoder in cubase 13 and the plugin is great, more flexibity (and stability) than the TAL vocoder. But the fact that you have to add gaps between the midi chords makes it somehow unusable… an alternative could be to use an external sidechain, e.g., retrologue2. the setup gets a little bit more complex, but you get full control over the carrier sound.

I am also a fan of the TAL Vocoder, but somtimes, it causes cubase to hang or even crash. but it gets that (to me) typical vocoder sound.

if i understand it correctly, one way for a bug report would be the issue group. however, there are 110k entries for cubase, not sure whether it will be noticed there…

Don’t use the internal synth. Replace it with any VSTi synth or any audio for that matter. You just have to side-chain it. Look at the Vocoder section of the Cubase 13 Plugin reference. Not in any version prior to 13.
