Pro One (100) |
| Description |
Great and powerfull analog synth from 70's
This one is in excellent cosmetic conditions (I am the 2nd owner and always kept in free-smoked studio as the 1st owner too)
the Pro-One can generate many of the same sounds as the Prophet-5 and Prophet-10, capable of supremely punchy bass lines and distinctly ripping leads, fueled by two VCOs, referred to as Oscillator A and Oscillator B.
he Pro-One has extensive modulation provision with three modulation
sources available, featuring Filter Envelope Generator, Oscillator B, and a separate LFO. Each can be mixed and routed for either Direct or Wheel-controlled modulation. On the back of the unit, there are Audio, Filter CV, Gate/CLK, and CV inputs.
Other features include a 40-note sequencer, an arpeggiator, Pitch and Mod wheels, Repeat and Drone switch, Single and Multiple-triggering keyboard modes, and the unique Automatic Glide, enabling one-handed complex, “tuned” pitch bending sounds. |
