Great Synth :-) though i miss a few things:
1. Ringmodulation/AM between oscillators or faster LFOs (you can modulate oscillator volume but the LFOs only go up to 200 Hz)
2. Selectable root-note when importing wave-tables: Currently you can import a .wav file but it just splits it into 2048 samples long frames. The correspondig root-note is quite low. My idea would be that you can select a root-note before generating the wavetable from the .wav file. The audiofile is then split into (up to 256) frames with sample-length corresponding to the root-frequency. With that method it would be super easy to just grap some funky audiofile and resynthesize it as a wavetable.
Best,
Adrian
