"The Drumfire DF-2000 is a 2 channel rackmount drum synth.
The 2 channels are identical, with their own Trigger-In and Audio Out sockets.
Each channel is a mini analogue synth drum module, capable of producing a wide range of electronic drum sounds, and since every parameter is defined by a knob, it's highly tweakable.
The 2 drum channels each have
SENSITIVITY-controls pickup/trigger in sensitivity
OSCILLATOR DECAY-controls decay time of the synth oscillator
NOISE DECAY-controls decay time of the noise sound
SWEEP-alters oscillator frequency
CLICK (Switch)-adds a click sound to the attack
PITCH-changes oscillator pitch
BALANCE-controls balance between oscillator/noise
VOLUME-output volume to mixer
One out can be daisy chained to the next channel's input, so cascading up to a 2 oscillator synth drum sound! Great for crazy/weird/techno-y drum sounds."
