Analogue Solutions | Polymath
Polymath is an analogue synthesizer. The voice and modulation circuitry are entirely analogue, using all discrete and op-amp components.
Polymath is for use any time you need analogue sound effects, fat basses, screaming leads, beeps, tones, zaps, and all the other crazy sounds associated with analogue synthesis. In Unison Mode the sound is big.
Polymath has an audio input socket, so you can feed external sounds into the on-board analogue filters for analogue processing. This sound could come from an audio track on your DAW (for example a vocal track), from a sampler, or even, say a CD player.
Polymath is a 4 voice paraphonic analogue semi-modular synthesizer, with built in analogue step sequencer, arpeggiator and spring reverb. The circuit designed is quite literally from the 1970s. It has a very old sound. And is full of character. Analogue synths of the 1970s had that just ever so slightly drifty sound that many would agree is so much more full of life than many of its digitally sanitized analogue synths.
Up to four note chords can be played, since it has four separate oscillators. However, it only has one filter and one amplifier section. Polyphonic synths usually have a filter/vca/envelope per voice/oscillator.
The control voltages from the MIDI-CV converter are prepatched to each VCO, VCF, VCA, EGs. However, in many cases the signal can be switch out via a toggle switch. In a similar way to above, some other signals are pre-patched to other circuits, but once again can be ‘turned off’ via a control or toggle switch.

|VCO||Voltage Controlled Oscillator||DCO||Digital Controlled Oscillator|
|LFO||Low Frequency Oscillator||Sub||Sub Oscillator|
|VCF||Voltage Controlled Filter||VCA||Voltage Controlled Amplifier|
|Velocity||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.||Aftertouch||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.|
|Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.|
