Granular Synth updated to build #105

[ColinP]

The PITCH knob (and its setting by randomization or mouse drags on the waveform display) now locks to whole semitone steps.

This is more muscially useful in the vast majority of cases and fixes a nasty problem with MIDI control of the knob - the 7 bit CC resolution resulted in all kinds of weird and very unhelpful values when using a control surface.

The minor drawback from stepped control is that it's no longer possible to do fine tuning or smooth manual pitch glides using the PITCH knob when the OMDU switch is in the O setting but you can still achieve this by using CV.
