The Prophet-10 module puts ten voices of Sequential’s legendary analog poly synth on your desktop. Like the full keyboard version, it’s “the best of all Prophet-5s” because 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. The result is as pure a renewal of an analog classic as you could wish for, with the authentic, muscular sound of the original and the roadworthiness of a state-of-the-art modern instrument.
In addition to sourcing genuine Prophet-5 hardware components, they did extensive research into exactly what made the original sound the way it did — warm, organic, and alive. We found that much of this desirable character was due to slight fluctuations and differences in the response times and frequencies of the individual VCOs, filters, envelopes, and amplifiers from voice to voice.
To give the same mojo to the new Prophet-10, they created the Vintage knob. Use it to dial in as much old-school randomness as you’d like. Go from a very stable “4” — as in Prophet-5 Rev4, which is how we refer to the new version in house — all the way to “1,” as in Prophet-5 Rev1, the rarest and most temperamental of all Prophet-5s.
In addition to the unmistakable tone of its oscillators and filters, much of the classic sound of Prophet-5 was the result of Poly Mod, which is faithfully present here as well. True to the original, modulation sources are Filter Envelope and Oscillator B. Destinations include Oscillator A frequency, Oscillator A pulse width, and low-pass filter. The range of sounds possible defy its simplicity. Another welcome reprise is Unison mode, which now features configurable voice count (1-10 voices) with variable detuning, and chord memory. And now Glide works both in and out of Unison.
The Prophet-10 bi-timbral, meaning that it can play two different programs simultaneously. In this mode, each program is allocated five voices. Use this capability to layer two programs for thicker, more powerful pads and chord stabs. Alternatively, split the keyboard into two independent performance zones and play synth bass in the lower range and leads or chords in the upper range.
