Rock-solid oscillators
The twin beating hearts of the Prophet-5 are its dual Curtis analog CEM 3340 VCOs. Found on Rev3 Prophet-5s, the CEM 3340 VCOs are rock solid, with virtually no tuning drift. Their implementation in the Rev3 represented a major turning point in the design of the Prophet-5, enhancing the performance and sonic quality of the powerhouse synth. As on the legacy models, the Prophet-5 Rev4 offers simultaneous selectable waveshapes — sawtooth and pulse on oscillator A, and sawtooth, pulse, and triangle on oscillator B, with pulse width modulation on both and hard sync for shaping the timbres of the oscillators. With the CEM 3340 VCOs, you have the ideal building blocks for creating harmonically rich analog patches.
Lush, dreamy analog filters
Dave and the team at Sequential went above and beyond for the Prophet-5’s filter section. Users can choose from two authentic re-creations of classic four-pole resonant lowpass filters — the Dave Rossum-designed 2140 (a modern update of the original 2040 found on the Rev1 and Rev2), and the Doug Curtis-designed CEM 3320. The 2140 is perfect for gristly bass lines and dense, sweeping pads, while the 3320 excels at dialing in laser-sharp high end for cutting lead lines. Both filters can be driven into maddening self-oscillation, and a dedicated 4-stage ADSR filter envelope gives you ample control over shaping the behavior of the filters.
Mountains of modulation
If you’re the kind of synthesist who likes to strip things back to the INIT patch and dig into some serious sound design, then the Prophet-5 is for you! Though simple, its modulation controls give you incredible flexibility to create vintage-style basses, leads, pads, brass, and strings, or generate brain-bending textures and effects. The Prophet-5’s single LFO offers three simultaneous waveshapes — sawtooth, triangle, and square — and an initial amount control. Use the LFO for pitch modulation and PWM of oscillators A and B or send it to the filter cutoff. And assign any of the mod destinations to an external mod wheel. Additionally, Prophet-5’s Poly-Mod section lets you use the filter envelope and oscillator B as mod sources for affecting oscillator A’s frequency and pulse width, as well as the filter cutoff.
Deluxe performance controls
One of the most appealing aspects of analog synthesizers is the tactile experience of interacting with their knobs, switches, sliders, and wheels — and the Prophet-5 has plenty! With a knob-per-function design, the Prophet-5 treats you with detailed control over every parameter, so you can turn patches into living, breathing performances. Plus, the Prophet-5 includes inputs for volume, filter cutoff, and sustain pedals.
