Red Synton Syrinx Audio Demo

video upload by Edwin Kiddo

"Audio demo of my Synton Syrinx. This one has been serviced and the power input changed from 220 to 110V.

The Syrinx uses seven Curtis chips for its VCO's, VCF's and envelopes. It has two analog VCO's, a sub-oscillator and three flexible voltage-controlled filters. You can switch between the three filters for either a 24 dB lowpass, or two bandpass filters, and they can be patched in four different ways (series/parallel). Additionally the Syrinx has two LFO's, FM, PWM, osc-sync, 2 ADSR envelopes, ring modulation, portamento and a cool touch-pad that can control various parameters from pitch-bending to the LFO rate. The Syrinx's Mixer section lets you adjust levels for each VCO and the sub-osc as well as the Noise Generator and Ring Modulator. Unfortunately, being released around 1983, the Syrinx just missed out on MIDI and patch memory options.
