A 5-voice polyphonic analog synthesizer with a 61-note keyboard, released in 1978. Being an "essential" vintage synth, it is still widely used.

The P5 features 2 VCO:s per voice, as well as a white noise generator. Available waveforms for the oscillators are square, pulse, triangle and sawtooth.
The filter is a resonant low-pass VCF. The LFO can modulate pulse width or pitch. An ADSR envelope generator is available for both the VCF and the VCA. Furthermore, a pink noise generation is included for modulation.

The first versions contained 40 user programmable patches. It was raised to 120 in revision 3.3.

Although the P5 was (and is) extremely popular and great sounding, it had its share of the usual analog synth problems. The tuning was very unstable in the early revisions, and there was no MIDI support. Some users also believe that while swiching from SSH to CEM chips in revision 3 improved the general functionality, it made the P5 sound inferior to the earlier versions due to missing lower frequencies.
