"This auction is for a 1974 Paia model 2720 Modular Synthesizer. The synth includes 13 patch cables and 5 audio cables and a complete set of manuals for every module as well as the assembly instructions, patch diagrams, and a user manual.
The 2720 was sold as a kit of parts and was the first synth to incorporate, in one unit, its own power supply, all electronic analog music modules and an integral keyboard controller. As opposed to earlier models, it can literally be moved to any location and simply plugged in. The synth was designed by John Simonton, Paia founder. The synth is completely operational and like new with the following flaws noted:A rubber foot on the front right corner has disintegrated.
The low 'B' key on the controller sticks a little.
Keyboard calibration is off and needs to be re-aligned (a periodic task)
The synth has not been used for many years, but was recently activated to record some vintage sounds. The synth has a lot of historical value and is extremely educational since it uses very basic components to electronically generate sounds. I am the original owner and builder and now need the space for some more equipment. Here are the components of the 2720:
Power Supply - with variable outputs
VCO - Voltage Controlled Oscillator w/3 wave shapes
ASD - forerunner to the ADSR called a Function Generator
LFO - Low Frequency Oscillator w/ 3 bands and variable frequency
Noise generator
Band Pass Filter w/Q control
Low Pass Filter w/control
VCA - Voltage Control Amplifier w/ control
Keyboard Controller
Variable Pitch and Trigger shapes for the Keyboard Controller
More info on this synth can be found at JohnnyPumphandle.com Shipping weight is about 20 pounds"
That's about the cleanest 2700 I've seen. Very nice.
ReplyDeleteI built one of these back in '76 0r '77. This is a very fun and portable synthesizer. I put long screw-on wooden legs on mine, so that I could set it up like an electric piano and use it as a regular band instrument. Great memories!
