Vintage synthesizer demo track by RetroSound
all sounds: Sequential Circuits Pro-One Analog Synthesizer from the year 1981
drums: Roland TR-808 synced with the Pro-One Arpeggiator

for me one of the best monophonic analog synths ever. perfect for basslines and fx sounds.

The Pro One was basically Sequential’s attempt at taking their legendary Prophet 5 poly-synth and packing it into a compact, inexpensive, monophonic analog synth! It has two VCOs, a great 4-pole lowpass filter, two ADSR envelopes (one for filter), and a compact three-octave keyboard. With a Pro-One, you can easily create punchy analog bass-lines and leads or quirky analog synth effects.
The Pro One is an extremely flexible synth with lots of modulation possibilities (ie: the filter, VCO B and LFO can modulate VCO A or B frequencies or pulse widths, or the VCF). There’s also an onboard sequencer, something common on many Sequential synths but not often found on other monosynths of the time. It is very basic, however, storing only two patterns and up to 40 notes max. Also, only pitch info is recorded (and in step time only); you can not assign a note duration to any notes. So it’s basically a short melodic sketch-pad…but useful. Also onboard is an arpeggiator which has UP and UP/DOWN patterns.
