This synthesizer has some issues:

- Some of the LED lights no longer work (for example, the voltage processor, maybe others)

- It appears the regular outputs of the voltage processor do not work but the inverted outputs do work. The sliders appear to affect the inverted output.

- The Env Follower appeared to work.

- I am uncertain about the Ring Mod, sometimes seemed distorted but sometimes Ring Mod creates some weird sounds by nature so not positive there

- Some of the routings/inputs don't seem to work right. For example, I think it was the VCO1 FM input on VCO2 did not seem to work correctly but routing say VCO3 to one of the other FM inputs on VCO2 did seem to work. So I'd say some routings/inputs do work, some do not and I cannot say for sure which do and which do not.

- The manual trigger button tends to stick when pressed.

Because of these issues, there could be others, I cannot say for sure. Many of the function do work but some do not. I'm selling the synth as-is with no guarantees.

Includes power supply and original box.
