The Compound Recording Studio

Technics AX7 Synthesizer


This is a wacky synth. I haven't decided if I love it or hate it. Powered up it is covered in lights.. so it has that going for it.


Specs! Specs! Get yer specs here....

  • 8-polyphonic, 4-part multitimbral PCM synthesizer workstation with a PCM drum machine.
  • 3 OSC architecture without a filter. A sound is made of Attack Source (1 OSC) and Body Source (2 OSC).
  • The Attack Source is basically a short transient sample like Roland D-50 / D-110 .
  • The Body Source is a combination of 2 samples called Basic and Harmonics. They seem to be basically single-cycle waveforms, and some Harmonics waveforms includes 'Spectrum' type longer loops.
  • The Basic sets the overall character of the Body Source, and the Harmonics determines the second waveform added to it. Harmonics volume works like a static filter.
  • 2 Amp envelopes for Basic and Harmonics. They have ADSR relative change parameters.
  • Both Basic and Harmonics have 2 LFOs for pitch and amp (that is, 4 in total), controlled by rate variation, depth, speed and delay.
  • Auto bend can be set differently for both Basic and Harmonics. Portamento is also available, which was a rare feature for PCM synths in the 80s.
  • 2 FX - chorus and reverb.
  • Big custom LCD display with 10-step parameter graphics.
