The filter cutoff frequency is affected by a dedicated five-stage (DADSR) contour generator. Its character is as you would expect - warm and flexible, but perhaps not as aggressive as some people might like. This offers resonant 12dB/oct and 24dB/oct modes, the latter of which will self-oscillate at high resonance settings. The output from the oscillator section is then presented to the same Curtis low-pass filter used in the Prophet 08. and you can hard-sync osc 1 to osc 2 for the usual range of effects, which the Rev 2 does rather well. In addition, an oscillator ‘slop’ parameter allows you to add errors to the pitches of each oscillator to turn your nice, stable DCOs into horrid, inconsistent VCOs. You can waveshape any of the oscillators’ waveforms (not just the pulse wave), picking an initial shape and modulating it as you choose. There’s also a sub-oscillator an octave below osc 1, and a white-noise generator. If you switch off Layer B, then Layer A is played with the instrument’s full polyphony.Įach voice offers two detunable, mixable DCOs with optional key sync (which initialises the waveform when you press the key) and the ability to be disconnected from the keyboard. Initially, you couldn’t copy sounds from one Program into another, but this was corrected in v1.0.7.2 of the OS. You can audition and edit either Layer individually or while listening to the composite sound, and copy or swap Layers within a Program. For the smaller model, layering reduces the polyphony to four notes while, for the larger, it’s reduced to eight notes, as you would expect. These can then be layered or positioned either side of a user-defined split point. Both versions are bi-timbral, allowing you to create a separate sound, each with its own effect, arpeggio and sequence, in Layers A and B of each Program. The Rev 2 keyboard and its desktop module are each supplied in two versions: an eight-voice model and an otherwise identical 16-voice model, and you can upgrade the former to the latter using the Rev 2 Expander Kit. So today’s question is, will the Prophet Rev 2 be another good’un? The Voicing I’ve reviewed all of these, comparing them with their ancestors - the Prophet 600, the Prophet 5, the Pro One and even the Oberheim 4-Voice - and, without exception, I’ve been impressed. Looking back, the chattering classes had significant misgivings when DSI did so, but the Prophet 08 won over many (although, if we’re honest, not all) of the doubters, and paved the way for the Prophet 12 and the Pro 2, the Prophet 6 and the OB-6, all of which have offered different flavours of hybrid analogue/digital synthesis. It’s hard to believe that it’s been nine years since DSI reintroduced the Prophet name to a world crying out for recreations rather than digital emulations of classic analogue synths. The Rev 2’s attractive feature set and inviting price tag could make it the most popular Prophet yet.
