PixelWave from Alex (maker of the awesome Sunvox) has been updated with some great new features:
- export to WAV (via iTunes File Sharing);
- copy to pasteboard;
- nine predefined waveforms;
- changeable number of octaves (from 2 to 6);
- option to disable the echo;
- option to apply the Low-Pass filter (smoothing);
Not bad at all for just $0.99.
