101-VCO vs SH-101 + 101-VCO Tuning Mod [Demo 4]

video by gstormelectro

"Today, I am comparing my 101-VCO to the original Roland SH-101 synthesizer.
How close to the original is my 101-VCO?
Saw, Pulse, Pulse Width Modulation, Sub, and Noise waveforms.
The SH-101 did not have the Triangle waveform.
At the end of the video I'll play both of them together, just for fun.

I'll also show you an easy mod for the 101-VCO so that it's pitch CV can
match the tuning of the original SH-101.
It involves adding a 1206 470K resistor to R19 previously denoted "DNP".
All 101-VCOs I make and sell henceforth will have the resistor already installed.
And tuned to match the SH-101 as it should be.

Left Channel = 101-VCO
Right Channel = SH-101

1:45​ Audio Comparisons
4:25​ Both at the same time, just for fun"
