Drumfire DF-500 Drum Synthesizer

via this auction. This one in via Bryan K who was previously featured in this post. The Drumfire was used on most of the tracks for that release. Some details from the auction:

"This is what is also known as a "drum brain"... a synthesizer for drum sounds made to be triggered by contact mics (drum triggers) attached to a regular drum kit or pads or whatever you want, like regular audio signals.

In the picture you'll see some contacts that I'll include for those that want to make their own triggers. I have a bunch, so within reason I'll include however many you need.

The Drumfire is in great shape, everything works well.

Here's the lowdown... there are five channels that can be triggered independently and each has controls for the trigger input sensitivity. You can take audio output from each track individually or just use the stereo master output and have the sounds panned however you want.

The sounds on each channel: there's a triangle wave and a noise source with the addition of a "click" sound which adds attack. There's a "balance" setting for mixing the amount of oscillator or noise sound you want. Individual settings for oscillator and noise decay which vary in length from a short "click" to a long decay (longer than you'll want for percussion). You can adjust the pitch/frequency of the oscillator from sub-audio to midrange. There's a sweep setting for making the sound either sweep up or down in frequency (think disco toms).

Oh no, it's not just for disco toms.... it's fun for experimenting with by feeding the trigger inputs with different sounds. I made a ground loop by connecting the trigger IN of channel one to the footswitch IN and then taking the output of channel 1 into channel 2. By chaining them together and keeping the decays very short some interesting crackly sounds can be had, a low frequency noise source. Listen here to track 3 here. I used this thing to get sounds on other tracks there as well.

I've heard the electronic group Pan Sonic had one of these, and I recognize some of its sounds on their first album. Also, David Tudor used a percussion synth on his piece "Phonemes" and I could swear he used this model. Like I said, fun for experimenting with... for more than just drum sounds."
