Restoring TWO Sequential Circuits Prophet 10 synths and stacking them with MIDI (40 Oscillators)!

The techs at Bell Tone Synth Works vintage synth repair workshop recently restored TWO amazing Sequential Circuits Prophet 10s and since we also retrofitted both with MIDI, we decided to chain them together to create a 20-voice, 40-oscillator monster polysynth! Here's an overview of what goes into restoring one of them, and a demonstration of the "Prophet 20" in action, also featuring our lovely Hawk HE-2150 stereo tape echo. This is like playing FOUR Prophet 5s at the same time!

Sound demonstration starts at 6:42
(in case you don't care about the "tech stuff")
