Thanks for the free download but I fear there is a bug in this version. When playing legato (without overlapping notes) in mono mode with anything but very short decay times, the filter envelope doesn't get re-triggered from zero. This results in the filter staying open when playing legato notes. So when you play freely it sounds like the filter opens up randomly in a hard to control way. If you program or quantize your performance you can alter the note lengths so it sounds consistent but that's a clumsy workaround.
Is this a bug or was it intentional to cripple this free version?
