Tweakbench rebar

Rebar is a drawn Waveform monosynth using Mark andrews` step oscillator. simply draw your waveform using the Sliders, Create your envelope, and adjust the effects. both warp and delay effects have handy x/y based panels for live tweaking and automation crazyness. version 1.2 adds a truly drawable waveform panel (just drag your mouse across it), improved cpu performance, new patches, and better stability.
