Hi guys,
I have had some difficult times but a lot of happy accidents with this synth!
The best way I have found to retain some semblance of the original sample, or at least a better starting point is to first load one of the sustaining presets, then replace the audio file with yours. Try a few different
synth and waveform samples.
It may not give you exactly what you want, but the turnaround rate is a lot better than fiddling around.
