Sequential Circuits Custom Prophet 10
Here are some shots of my friend Riley's custom built Sequential Circuits Prophet 10. He worked at Sequential for many years
Custom built keyboard
Closeup shots going left to right. Above Poly mod and LFO controls
Middle shot -- Oscillators and patch selectors
Far right of Prophet 10 Differences from the Prophet 5-- Equalization controls (low mid high- right second row), Pedal 1 and Pedal 2 settings
Prophet 10 opened up
Main voice board is on the right side of the case. One more layer below this one. Each layer is basically a Prophet 5's chip set
Zooming in we see 5 CEM 3320 filters in a row. 2nd row of 5 chips (looking at far right of main board)
From a different angle a row of 5 CEM 3340 oscillators
