The Prophet '08 is a polyphonic analog synthesizer created by Dave Smith of St. Helena, California, USA, for Dave Smith Instruments (DSI), released in late 2007. As with DSI's other instruments, the Prophet '08 uses true analog subtractive synthesis, as opposed to many of the current crop of analog synthesizers, which employ DSP-based virtual analog synthesis.
Similar in functionality to the renowned Sequential Circuits Prophet 5 analog synthesizer popularized in the 1970s (also designed by Dave Smith), the Prophet '08 has an all analog signal path; however its envelopes are generated digitally. It is one of many analog synthesizers commercially available as of 2016[update].
The Prophet '08 is an eight voice analog synthesizer. Each voice is identical in architecture. The audio path is all analog, while there is some digital control of parameters.
The instrument can be played in three modes: eight voices all using the same program, "split" with four voices using one program and four using another program on separate sections of the keyboard, and "stacked" with four voices using one program and four using another program, both programs sounding on each note played resulting in a four-voice sound.
Each voice has two DCOs, one VCF, one VCA, three ADSR envelopes, and a noise source.
Each DCO can produce triangle, sawtooth, a predefined mix of sawtooth and triangle, and rectangular waves. The pulse width of the rectangular waves ranges from 0 to 100%, and has a dedicated knob. The relative levels of the 2 DCOs is set with a balance knob.
The pitch and pulse width of each DCO and the relative level of the two can be modulated.
The VCF is switchable between a 4-pole low-pass filter and a 2-pole low-pass filter. The cutoff frequency can be anywhere in the audio spectrum. Cutoff frequency and resonance each have a dedicated knob. Both can be modulated. There is a dedicated knob for keyboard modulation of the filter cutoff.
