en dit staat er over op vintagesynth.com:
A compact digital-analog synth. It has a very dirty sharp sound much like the Yamaha DX7. This is good if you are into the lo-fi sound of electronica. The Poly-61 can provide cool gritty basses or trippy analog sounds and fx. It's very easy to program, has a decent arpeggiator (with external sync) and the later Poly-61M models came with MIDI. An inexpensive alternative for lo-fi-quality DX7-like sounds, the Poly-61 can do some surprising things!
