a two oscillator synth where the two are beating and drifting in
and out of phase causing level dips and nulls, the various waveforms
and the sub-oscillator are in perfect sync allowing you to create
really solid bass sounds that bely their humble origins.
The single oscillator also offers pulse width modulation
that (sort of) goes some way to creating the sound of detuned oscillators
- that you can also mix in the sawtooth wave and the sub-oscillator
also adds to its sonic weight. I remember listening
to a friend's new tracks a few years ago - they all had some truly
wicked bass sounds and I commented that these must, of course, be
his Prophet 5. "No" he replied... "the SH101"!
It really can produce some superbly deep and rich bass sounds.
The filter is typically Roland and
sounds great. The ADSR envelope was punchy but there is only one
to control filter and amplitude but this is not the limitation you
might imagine especially as there is the option to select a simple
'gate' envelope for the final VCA. The LFO offers a good selection
of control waveforms for everything from subtle vibrato to whacky
The SH101 also featured an arpeggiator
and a simple step-sequencer.
