Circuit-Bent Alesis HR-16 Drum Machines

via this auction and this auction
Top: "This modified Alesis HR-16 features a custom designed Matrix Patching Grid from Diabolical Devices. A single LED patch pin connects bending points which will generate a wide variety of effects and glitches ranging from distorted, filtered and modulated effects to bizarre sounds and warped drum loops. The patch pins have LEDs that will react to ROM data and put on a light show. We have also incorporated a Master Pitch/Clock Rate Control with bypass switch and LED indicator. These are great machines and the HR-16 is loaded with original features. The modification unleashes the evil monster that has been hiding inside since the 80's.

Bottom: "Version B of the Diabolical Modified Alesis HR-16 features a very simple circuit-bending interface and master Pitch/Clock modification. ROM bending is accomplished using 12 position rotary switch, position 1 is off, 2-12 are a variety off odd reactions from bit-reduction, modulation, filtered sounds, to holding and staccato effects. The Pitch Modification is the same as Version 1.

Diabolical Modified Casio SK-1 Features:
20 point circuit-bending interface: Heavy-duty banana jacks on hand made turret board panels. This patch-bay allows you to scramble sound data as the synth addresses it, and the result is an endless variety of weird effects, noise, filtered and modulated bends, and one of a kind sounds (seriously, you might one hear some things once). It's a mixed bag of playable bends and bends that play themselves. These patch locations will affect each preset sound differently and also affect samples and chord/auto-play functions. This patch-bay also allows you to cross-patch with other bent devices for more ROM scrambling goodness.

Dual Square Wave Generator: A Diabolical Devices original. This mod allows you to patch the output of two different oscillators into circuit-bending patch locations. One oscillator is an LFO (low freq.), when patched to this point it will create controllable modulation, pulsing bends, and other strange reactions. The second stage is an Audio Frequency Oscillator which will react similarly to the LFO and create tunable overtones. Each Oscillator has an on/off switch with LED indicator, pitch/speed control, and a corresponding patch point.

Skew Bank: This is a great mod adapted from Reed Ghazala's original SK-1 bends, basically its a bank of 5 switches, when activated each switch will generate a different pulsing or semi-looping bend which affects original keyboard sounds.

Korg Oasys PCI synthesizer system

via this auction

"Original box, breakout cable, unused card...everything.

Also included will be a bonus disc given to me by the seller which has many programs written for this open sourced synth. They are all easy to find on the web but this way you won't have to go digging for them or download them individually.

It's like having every Korg synth from the past 15 years at your fingertips and so much more. Z1/ Prophecy/ Triton/ Karma...so many synths. The Oasys PCI is a card/program that Korg released before the standalone Oasys keyboard.

A quick read on this system will show that there are many dedicated, fanatic users still today. The only thing is that you need an old Mac or old PC to run it. Mac can't have higher than OS 10.9.3 on it and Windows has to be 98 or earlier. From the computer you interact with ADAT and MIDI."

Physical Touchscreen Knob for the iPhone/iPad

Physical Touchscreen Knob from adam kumpf on Vimeo.

"Here's another quick hack to add more physicality to touch screen displays. With a small knob, it's natural to grab it such that your fingers actually touch the screen making it nothing more than a physical prop to provide some tactile feedback. We experimented with conductive fabrics, copper tape, etc., but found that it worked best with simple physical objects.

EKOSYNTH Manual?

Anyone have a copy of the EKOSYNTH Manual? I linked to one in this post, but it looks like it is gone. I should have mirrored it then.
