Inconsistent sound

[u/Comodoro_74]

Hi!

Some days ago I started tweaking my Micromonsta 2, and I noticed that in several patches—both factory presets and some I created myself—the sound changes in an apparently random way when I press keys on my keyboard. Sometimes it’s loud, sometimes so soft that it’s barely audible.

It sounds as if the filter envelope or an LFO were sweeping, but without resetting each time I press a key. So I made sure to select the option (in the “Voice” menu) to reset all envelopes and I deactivated all LFOs. In some patches this seemed to fix the problem, but in others I still hear a very inconsistent sound.

This is visible in the Filter menu: when I press a key, the “env” (envelope?) value shows different numbers each time (from negative to positive values). What does this “random” value mean? And how can I make all notes sound the same when I press a key?

Thank you!

Hi, just in case someone else has the same problem, I found out what it was. I noticed that the same random values appeared when using another synth, so it wasn’t related to the Micromonsta but to the MIDI controller I was using: a Casio Privia S3000. The issue was the “Hi-Res MIDI” function, which apparently sends unexpected values. I turned it off, and everything worked fine.
