Effects , Arpeggiator and Sequencer
Like the REV2, Prophet X includes two digital effects engines (per-layer) which complement the sample and synthesis engines. For the Prophet X, DSI have also included a great sounding rotary speaker effect (with decent overdrive too) to use not just on the organ samples, but any other sounds too. As the effects parameters are modulateable you can use the mod-wheel/other sources to change rotary speed (and parameters available on the other effects too). There are several decent reverbs (room, spring, hall, super-plate) as well as two delays, flanger, phaser, chorus, pan-spread, distortion (and the digital resonant HPF). In addition, there’s a separate digital high-pass/low-pass filter for just the sample engine (Tone) plus bit reduction (hack) and decimation (sample-rate reduction) for breaking up and granularising both engines. Let’s also not forget the per-layer MIDI syncable arpeggiator with five modes, and the up to 6-note polyphonic, key-transposable, 64-step sequencer (also clocks to MIDI but doesn’t output it) – handy as an ideas sketchpad or an extra layer to play back in sync with other hardware or DAWcreated sequences.
