Sequential Circuits Pro One analog synthesizer with Midi


The Pro-One is a monophonic, two oscillator synthesizer with a 3 octave, 37-note (C-C), keyboard.

It produces amazing bass lines and can do some very interesting effect sounds with the modulation section.

The keyboard action it is not that great, but hook it up to midi and you get basic midi with velocity sensitivity as wheel as modulation and pitch wheel.

Example Bass sound using the Pro One set to the positions shown in the images

Single note with varying velocity that shows how low velocity lowers filter frequency, harder velocity opens filter up.
