I downloaded the latest version, and I can still hear clicks after releasing a note. It is more obvious when soft clipping is on and cutoff frequency is low.
It is not a latency problem, as I experience this with even the most relaxed latency settings. I also tested this on a second system, with the same result.
When exporting a MIDI track as audio, and inspecting the waveform in an audio editor, I see indeed that the tail of notes is sometimes ended abruptly.
This is a pity, because I really like the sound of the MiniMgV, but this bug makes it unusable for me.
