Here we have Sequential's classic flagship monosynth! A dual oscillator beast with arpeggiator, the Curtis filter, sequencer, and a simple but powerful modulation matrix. The Pro One is well known for its sound and has been used by countless musicians since its release.
This Pro One was just serviced, keybed assembly cleaned and rebuilt, new CPU and socket installed along with the MTG Turbo Midi upgrade kit. Mod and pitch wheels were once cracked and broken but have been repaired.
