The Prophet-5 module gives you the power of Sequential’s legendary analog poly synth on your desktop. Like the full keyboard version, it embodies all three Prophet-5 revisions: Rev1, Rev2, and Rev3 - through the use of genuine Curtis analog VCOs and filters (as in the Rev3) as well as new 2140 low-pass filters designed by Dave Rossum, like the 2040 filters he designed in the original Rev1 and Rev2. A Rev switch lets you choose between the two filter designs. It also adjusts the Filter Envelope’s shape and response to match the original Prophet Rev 1/2 or Rev 3 respectively. Key Features: Two authentic CEM 3340 voltage-controlled oscillators per voice Simultaneously selectable wave shapes. Oscillator A: sawtooth, pulse. Oscillator B: sawtooth, triangle, pulse. Pulse width per oscillator Hard sync: Oscillator A syncs to Oscillator B Low frequency mode (Oscillator B) Keyboard tracking on/off (Oscillator B) Video: https://youtu.be/1acVKBsctrwProduct Specs Item Number: 20818 Make: Sequential Model: Prophet-5 Module Condition: Brand New Finish: Black Categories: keyboards-and-synths ⇒ analog-synths Made In: United States MPN: SEQ-1100 UPC: 855346000616
