Sequential Prophet 6 Keyboard

The Prophet-6 takes the best qualities of the original Prophet-5—true voltage-controlled oscillators, filters, and amplifiers—and adds enhancements such as studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more. The result is pure, unadulterated analog tone with the stability and reliability of a state-of-the-art modern synth.
Central to the warm, punchy sound of the Prophet-6 are its two newly-designed, discrete voltage-controlled oscillators (plus sub-oscillator) per voice. Continuously variable waveshapes provide the tonal palette with triangle, sawtooth, and variable-width pulse waves. There are two discrete filters per voice—a four-pole, resonant, low-pass inspired by the original Prophet-5 filter, and a two-pole, resonant, high-pass filter. Voltage-controlled amplifiers complete the all-analog signal path.
The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus and phase shifter. While the effects themselves are digital, with 24-bit, 48 kHz resolution, a true bypass maintains a full analog signal path. There’s also an independent stereo distortion effect, which is 100% analog.
Also present from its classic predecessor is a Poly Mod section, with enhancements. True to the original, modulation sources are filter envelope and oscillator 2 (both with bi-polar control). Destinations include oscillator 1 frequency, oscillator 1 shape, oscillator 1 pulse width, low-pass filter cutoff, and high-pass filter cutoff. Another welcome reprise is Unison mode, which features configurable voice count (1-6 voices) and key modes. The polyphonic step sequencer allows up to 64 steps and up to 6 notes per step. You can create sequences polyphonically, with rests, and sync to an external MIDI clock. The full-featured arpeggiator can be synced to external MIDI clock as well.
