"- VCO 1 and VCO 2 signal Out `s for filters or VCO FM cross modulation so that the VCO's can now be used for clay modeling (eg, clay modeling for each VCO cross-modulation) or the filter (for funky filter FM). In addition, they can also be worn separately as an audio modules to be similar to other filters or further processed.

- PWM IN
the pulse width of VCO-1 can now by a control voltage (eg LFO or envelope) to be modeled (good for floating sounds)
also been:
- The tuning knob for filter and Vco `s were in the inner set further forward (see pictures below), we can now more easily as the Charachter the filter from tender to angry dissemble
