Pearl Syncussion SY-1

via this auction
"It has two channels and can be triggered by a synthesizer, drum machine or one of the two included pads.

There are sensitivity knobs at the rear to adjust for a strong or weak signal.

When used with the pads the sounds vary depending on how hard you hit the pad making it truly expressive and musical.

Also, because this is pure analogue, there is no processor lag (latency) so the sounds are heard instantly, essential for getting a good groove.

The SY-1 has 6 preset oscillator modes, and on each channel there are 8 sliders which control, tune, decay, width, sweep speed, sweep range, lfo speed, lfo range, and output.

There are also sliding switches to control "sweep up-off-down" and "lfo square wave-off-saw wave" and sample and hold.

Can use with or without drum heads, drum heads activate triggers which could also be activated by sequencers or triggered outs on a drum machine or electric drum kit."
