External audio input has been added and you can route audio in and process with the filter OR external audio source can be used to FM the filter (depending on the FM - VCF switch at the back, see pics).
Other features include a Drive pot used for driving the filter input harder for a more saturated over driven sound (at lowest setting it is the normal Sh101 sound).
PWM (Pulse Width Modulation) can now use all the available LFO waveforms, selectable by a pot/switch (not just limited to the triangle waveform as on a normal Sh101) PWM modulation waveform is also completely independent from the main LFO setting (so LFO and PWM can use different waveforms simultaneously)
There are several new 3.5mm jack sockets:
1) CV filter input for external control
2) an audio input to the filter for processing and
3) an LFO trigger input to trigger the LFO from a external source."
