The Tama TS-305 is a six channel drum synth module. It can be used on a desktop or mounted in a rack. Each channel is a miniature analog synthesizer, capable of producing a wide range of electronic drum sounds. Since every parameter is defined by a knob, it's highly tweakable. Attack, Decay, Noise, Bend, Tune, Trigger sensitivity, are some of the parameters that can be adjusted directly with knobs. This can be used with drum triggers, gate source, even line level audio...the threshold is very flexible. Each channel has its own preset sound, as well as its panel setting.This Tama is in very good, working condition.
