I am not sure if you can help me. I have bought korg's mono/poly soft synth and every time I hit space bar to stop and then restart track it resets the presets to a default. I am not sure if this is a vst problem. Any help would be great. I am running ableton 8.2.7 on a mac 10.5.8
There is the possibility that a clip somewhere is sending a Program Change message to your synth. I'd look into that. Set it to None (or a preset you want)
