PAiA | 2720 Synthesizer


The Paia 2720 Synthesizer was a self contained modular synthesizer that you could build from a kit and add modules and features as desired. It was advertised heavily in many electronic magazines and and as a featured article in them. the instrument being modular made it extremely flexible and cost effective for musicians to get into synthesizers. Paia founder John Simonton published a series of articles on the 2700 series in Radio Electronics during it's time. 

It has a single Voltage control oscillator with Ramp, triangle, pulse or pulse width. It also has a EG aka in Paia lingo as Function Generator.
With manual trigger button and attack and decay, and variable attenuator. 2 filters one low pass and the other bandpass with resonance control. 

Additionally there is a Low Frequency Oscillator and Voltage controlled Amplifier, a 3 octave keyboard with glide control and pitch transpose with two trigger outs and one control voltage out.

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.
