Thanks for recommending
There’s a SH-101 starter patch in the project (Row 1) that you can use as a base, but these are the steps to create authentic SH-101 patches in the MC-707….
PTL 1 = Square wave, PTL 2 = Saw. PTL 3 = Square (to match the three sub settings of the SH-101, either at -12, -24, or -24 with 96 PW), PTL 4 = PCM -> White Noise
Use the VCF (Flat). Filter slope -24dB. Set Key Tracking to taste between 0 and 127.
In the Sound Settings turn on Portamento if you want it, then select Legato On or Off as needed.
For Gate mode, use the Amp envelope at Attack 0, Decay 0, Sustain 127, Release 0, then use the Filter Env Amt (positive values only) and the Filter envelope to shape the filter.
Adjust the Cutoff/Resonance. For Envelope mode, make sure the AMP ENV and FILTER ENV have identical settings as there’s only one envelope on the SH-101.
Assign either the Triangle, Square, Random or Noise waveform to LFO and use it to modulate Cutoff or Pitch.
Use the PWM setting to modulate the PW of Partial 2. I found setting the Sys Ctrl knob to Filter Env Decay is really useful, you can set your three performance knobs to Cutoff, Resonance and Filter Env Decay for live tweaking.
