High and mighty- The ARP 2500 w/Don Slepian @ RetroLinear

RetroLinear

"Resurrected from the dead, the mighty ARP2500. A rather lengthy restoration project requiring nearly countless hours of reworking, development of new circuits, reverse engineering failed potted modules to restore operation and improve performance.

Don Slepian paid us a visit and kindly recorded around 20 minutes of musical snippets on the ARP2500 which has been arranged as a single track for your enjoyment!

Many thanks to Don for his musical expertise in steering the ARP2500 and Edwin Kiddo for his 2500!"

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.

Polyphony - Monophonic
Oscillators - 2 VCO's (tri, saw, square, PWM) plus 1 sub-oscillator, ring modulation and noise gen.
LFO - 2
Filter - 2 Bandpass filters (Peak 1 & 2) and 1 Lowpass 24dB/oct filter. Individual cutoff and resonance controls, ADSR Envelope, Keyboard Tracking and LFO modulation
VCA - 2 ADSR filters (one can modulate the VCF)
Keyboard - 44-keys (3 1/2-octave, no velocity, low-note priority)
Arpeggiator - None
Sequencer - None
Memory - None
Control - CV / Gate (Moog type). Touch 'N Bend Pad.
Date Produced - 1983/84"
