Each of the Bit 100’s oscillators can mix together 3 different waveforms; Triangle, Sawtooth & Pulse.
The latter’s symmetry can be adjusted - please see the section below on ‘Pulse Width Modulation’.
From the diagram below, use switches (1-3) to turn on and off the Triangle, Sawtooth & Pulse waveforms
respectively.
Parameter (4) controls the pulse width (symmetry) of the pulse wave. This setting does not effect the triangle or
sawtooth waves, so if Pulse wave is set to off, the pulse width parameter will have no effect.
Parameter (5) controls how much velocity data ( how hard keys are struck) will effect pulse width; with higher
settings, harder velocity data will lead to narrower pulse width.
DCO1 can also output a random waveform; white noise. Use parameter (6) to adjust the volume of this noise
source.

The Manx Bit 100 v2 has two important features which were missing from the original Crumar Bit 100:
Independent volume controls for DCOs 1 & 2,
and Pulse Width Modulation (please refer to the next section for a definition).
These Parameters are located in the “DCO CONTROL” section of the parameter map.
Use Parameters labelled (7) above to control the volumes of the two oscillators. (If the instrument exhibits
unwanted distortion or overdrive, this may be a good place to lower the volume, since the distortion may
be resulting from the filter being over-driven.)
Use Parameters labelled (8) above to control PWM depth for each oscillator; the modulation source is
fixed as LFO 2!
