"The RS100 24dB/oct low-pass filter imitates the Minimoog's filter and exhibits almost identical characteristics in both the frequency domain (i.e. what it does to audio signals) and the time domain (i.e. its response over time to CVs). Below the cut-off frequency the response is approximately flat down to DC. With the filter fully open, it will pass signals approaching 20kHz."

"3 handmade analog drum boxes by Mr.AcidMachine.
Sorry about the poor sound quality from my camera.
Mrs.BassDrum is based on the TR-808 BassDrum with extra controls.
Mama Maraca is based on the TR-808 Maraca with extra controls.
Dr.Rimshot Clave is based on the TR-808 Rimshot/Clave.
Mrs.BassDrum and Mama Maraca sound pretty much the same as on the TR-808, while Dr.Rimshot Clave sounds a bit different, somewhere between the 808 and 909 Rimshot sounds, yet different and unique.
All 3 can be triggered by an external audio signal, drum pad, or voltage trigger.
All 3 can be powered by a 9 volt DC (negative center) adapter or a 9 volt battery. For sale on ebay tomorrow!! One day only!!"

"Up for auction are 3 handmade analog drum boxes by Mr.AcidMachine!! Mrs.Bassdrum, Mama Maraca, and Dr.Rimshot Clave are all included in this auction. All 3 are based on the Roland TR-808 drum sounds. Mrs.Bassdrum and Mama Maraca can make traditional TR-808 sounds plus more with the additional knobs, while Dr.Rimshot Clave sounds somewhere between the TR-808 and TR-909 RimShot and the Clave has a unique tone. Fully analog circuitry folks!! Play on the pads, plug in an external drum pad, a trigger out from a drum machine, or any audio signal to the IN jack to trigger the sound. Enjoy!!

"MIDI signals translated by R60. R60 fed to ZeR03. About halfway through I plug the R60 into a solid state oscillator, then the square wave out of that feeds the ZeR03. More info can be found here:

"Another feeble attempt at showing how a Kaoss Pad can be used as an awesome control surface for a modular synth. I'm horrible at talking while I'm syntherbating so most of my words are just rambling. Sorry.

The details... The MIDI from my KP3 is controlling Expert Sleepers' Silent Way DC plug-in hosted in Numerology. The CV is sent out of my MOTU interface via ADAT to ES-3 CV interface.

The signals generated by Silent Way are used to control the Make Noise Phonogene granular sampler. Audio from Phonogene goes into the Korgasmatron filter and then the zDSP.

The additional synth parts are all coming from the modular. Again I'm using Numerology and Silent Way to generate the sequences. The drums are from my Octatrack, all sounds sampled from the modular."
