OVERVIEW
The original Crumar Bit One’s oscillators used a proprietary mixture of digital and analog circuitry to produce
waveforms with both stable pitch and ‘grunt’.
From a user’s perspective, there is nothing unusual about the parameters which control the oscillators - most controls
are simply there to set the oscillators’ pitch; the rest are concerned with waveform selection, pulse width and volume.
Note: A cool feature of this synth is that you can select the three available waveforms to output concurrently.
Rather like the strings on a guitar, the oscillators are the point where the instrument’s sound originates from.
Two oscillators are better than one. With a twelve-string guitar, detuning the strings slightly can produce a richer
sound.
The notes on a piano usually have more than one string; moderate detuning of these strings will be required for the
piano to have a wholesome sound and over-the-top detuning will produce a ‘honky-tonk’ kind of timbre.
Bit 100’s oscillators can also be detuned, just by moving a ‘slider’ - this is a lot less bother than retuning a piano!
The Bit 100 v2’s oscillators are called DCO1 & DCO2 respectively; DCO stands for ‘Digitally Controlled Oscillator’.
TUNING
3
There are several external factors which determine the pitch of the SJ-2’s oscillators, including; master-tune control,
pitch-bend midi data, modulation sources and of course the keyboard itself.
In addition, the DCOs feature a number of switches and sliders to set the default pitch, ( rather like the tuning pegs
on a guitar ) :
1) Octave Selector - click in the area on the parameter map to cycle through the possible octave settings.
The currently selected octave will be underlined
2) FREQ - Use this parameter to select course pitch - 0-12, in semitone increments.
3) DETUNE - fine tune control for DCO2 only.
