Yamaha RX 17 + Patch Bay, Pitch Control and Joystick Mods
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
Video in the listing for another mod previously posted here.
"One-of-a-kind modified Yamaha RX 17 1987 12-bit programmable drum machine featuring two ROM modulation patch bays, a joystick for performance control of four pre-set effects (which may also be combined on the diagonal axes) and pitch control. These modifications generate an array of bit crushed, flanging, glitching, distorted, delayed, tonal effects, flams and digital noise. Five patch cables included- these can be 'stacked' for even deeper audio manipulation. The unit functions as normal when the patch bay is not in use. Only one available.
13 pads: tom 1/conga 1, tom 2/ conga 2, hi hat open/bongo high, ride/agogo high, cowbell/whistle, timbale high/ cuica high, bass drum/ tambourine, snare/rim shot, tom 3/conga low, hi hat closed/ bongo low, crash/agogo low, clap/shaker, timbale low/cuica low.
Accent, level, pan for each sound.
User Patterns: 999.
User Songs: 10.
Tempo Range: 40 - 240 BPM.
MIDI in/ out.
ROM Size: 26 PCM waveforms at 12-bit resolution.
Screen: 16x2 character display.
Weight: 1.5 kg."

"Here we have a custom circuit bent Texas Instruments Speak & Spell.
Operates as a totally normal speak and spell until you flip a glitch switch or turn a dial, etc.
Very fun to play, no right or wrong way to it, this bent talking synth is capable of tons of new sounds for you to record, sample or play live.
The added mods include:
1) Tone Oscillator button-creates a tone when depressed, the tone can then be manipulated with the theremin pitch cell, pitch dial or pitch body contacts.
2) Active Matrix Glitch-This mod opens up the membrane for random glitching dependent on where you touch the pad.
3) Ramble Glitch-Flip this switch and hit go and it will spew constant ramblings on and on and on and on.........
4) Dual voice glitch- causes it so speak In both a high and low voice at the same time.
5) Pitch Changing Body Contact-Touch this to lower the pitch, the harder you touch the further the change.
6) Pitch Changing Knob-Use this pitch control to change the pitch from incredibly high falsetto to super low, 8-Bit crushing growl.
7) Reset Button-Use this when you're ready for a change and the machine is rambling on its own, also serves as an OFF button.
8) Theremin Opto Cell Controller-Simply flip the switch, use the pitch dial to fine tune and you can play any sound emitting from the speak like a theremin, makes for some great effects.
9) Loop Switch with Advance Button-FLip this switch at any time to catch a sound that you can then mold and play with the other controls such as the opto cell and pitch dial.
10) Strobing LED for cool effect
It now features a 1/4" output jack that mutes the onboard speaker, allowing you can output this into your effects, amp, pa, etc.
These mods add tons of versatility and droning textures for your playing, recording and experimenting pleasure."

Isla Instruments Rhythm Imposer A/S

Click the auction link on top when you get there for additional listings.
"This is a heavily modified and circuit bent Alesis HR 16. The basic idea is that you can change the eproms and then mangle the sounds into oblivion by way of the knobs and switches which create all sorts of unpredictable and fairly brutal noises. The result can be anything from utter industrial magic to unusable garbage. Comes with a number of eproms incl. Korg, Linn DMX, Roland The machine is very unstable. Sometimes it works sometimes it just doesn’t. I have no idea how to make it more stable and when it comes on and produces sound, it’s absolutely random and unpredictable. The best way to think about this is as a sample source in that you have a tape running all the time and then pick and choose the best noises that come out of it. The great thing is that you would never ever come up with these sounds if you were to program them in a targeted and controlled manner. But on the other hand, it’s of course frustrating when it doesn’t come on at all. The starting bid is set accordingly. The buyer may wish to have a technician take a look at it."

Casio SK100 1986 8-Bit Sampler + Patch Bay & Pitch Mod
Note: links to listings are affiliate links for which the site may be compensated.
video upload by Canned Sound
via this Reverb listing
"Rare 1986 Casio SK-100 8-bit sampling keyboard custom modified with a 25 point modulation patch bay and pitch control section mounted on a metallic graphite externally attached console with a unique solid aluminium 1970s Hitachi 'wedge' knob. This is a weird, unpredictable, lo-fi and chaotic sampling instrument with a warm gritty sound which will inspire any alternative electronic musician and sound designer.
When the patch matrix is in use an array of warped effects, drones and loops can be generated; applying multiple connections produces an increasingly complex range of cyclic, pitch dropped, fractured, tonal, bit crushed, flanged, distorted, aliasing digital noise and bizarre sequences which affect any sound you record using the sampling feature. The pitch mod takes the sound up in pitch and down to crushing aliasing lows, also affecting the SK 100's pre-set sounds. Five stackable patch cables included.
Specs:
-25 point ROM modulation patch bay
-Pitch control function
-5 different dynamic envelopes can be applied to your samples (a long and short sample can be recorded and stored).
-Loop and reverse effects.
-The samples can be featured in the tempo adjustable onboard rhythm sequences.
-12 preset sounds
-12 preset rhythms
-Chord memory
-7 keyboard-based drum sounds"

Yamaha DD6 1989 Circuit Bent Drum Machine + Joystick Controller
Note: links to listings are affiliate links for which the site may be compensated.
video upload by Canned Sound
via this Reverb listing
"Yamaha DD-6 1989 drum machine featuring a 17-point modulation patch bay and pitch controller. The unit also includes an externally connected joystick module for manual activation of four additional modulation effects which are also combined on the diagonal axes for further processing options. Two latching/ momentary pre-set effect switches are also featured on this unit.
These custom modifications unlock an array of original sounds and rhythmic variations; making a single connection on the patch matrix can dramatically alter the output but applying multiple connections produces an increasingly complex, sometimes aleatoric range of reversed, tonal, bit crushed, flanged, distorted, aliasing and delayed sounds, additional accents, rhythmic patterns and digital noise. Additionally, the five included patch cables can be stacked for further sonic manipulation.
The patch bay and joystick affect the 100 tempo adjustable onboard rhythms and the velocity sensitive drum pads. The unit functions as normal when the patch bay is not implemented.
Mains (9- 12v DC) and battery powered (6 x AA), features a 1/4" output, no onboard speaker.
Dimensions: 42cm (L) x 27cm (W) x 12cm (H)."
