"Rare 1987 Casio SK-5 8-bit sampling keyboard custom modified with a 50 point patch bay. This is a haunted, lo-fi, challenging but rewarding instrument which will inspire any alternative electronic musician and sound designer. Nothing is obvious here- the keyboard itself doesn't always function as you'd expect while the patch bay opens up a world of experimental audio possibilities, far outreaching Casio's original intentions- remember, it isn't broken, it's just weird.

When the patch matrix is implemented, an array of warped sounds and effects are 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 the presets, onboard rhythms (speed rushes of laser, lion and drum samples) and any sound you record using the sampling feature. The SK 5 is also very good at producing complex drones and atmospheres which can be developed using the five included patch cables- these can also be stacked for further sonic manipulation.


Specs:
Sample reverse and loop functions
8 PCM tones: piano, vibraphone, dog, surf, trumpet, organ, chorus, flute.
10 rhythms: rock 1/2, disco 1/2, 16 beat, march, bossa nova, samba, slow rock, waltz.
Holds 2 samples: 8-bit PCM, 9.38kHz, approx. 1.4 seconds + 4 samples @ 0.7 seconds.
Sample tune +_ 1 octave
4 sample pads
4 rhythm pads: laser, lion, hi bongo, lo bongo
496 step sequencer
32 keys
6 envelope options"

Circuit bent Yamaha DD-8 - Experimenting with BandPass Filter

video uploads by batchas

"I wanted to tame the whistle which affects badly the DD-8 sound when the frequency is pitched down. This high pitched whistle can be very annoying as it can be extremely loud!
So I installed a Buchla 194 filter and a mixer on the DD-8. It enables me to divide the internal DD-8 signal into four frequency bands that I can adjust and mix together.
I use my Scrotum Lab’s Le Seq to modulate the frequency of the DD-8. Le Seq is clocked by the DD-8.
I made an external box with a voltage controlled clock divider. It allows to divide the weird DD-8 clock and drive my Le Seq external sequencer. Efx = Hologram Microcosm"

"Rare 1988 stereo keyboard which combines 100 2-op FM preset sounds, 10 rhythms and an 8-bit sampling function incorporating a four stage envelope generator and 9 adjustable DSP effects. This unit has been custom modified to include a 14 point patch bay (five stackable patch cables included) which allows for the further low-res processing of any sample recorded via the onboard microphone or phono input (jack to phono adapter included). The patch matrix generates aliasing, bit crushed, stuttering, bleeping, warped digital degradation, offering numerous unique lo-fi sound design possibilities.

Talk with Yukes——“ Why I Prefer an Electronic Instrument, Instead of an Acoustic One?"

video upload by Meng Qi

"Yukes excels at all kinds of plucked string instruments. He told me His stage name Yukes is derived from the word 'Ukulele,' and when he put his name into Google Translate, it resulted in '玉刻' (Yukes), which means 'Jade Carve' literally in Chinese. In our culture, one well-known adage goes like this: 'Jade needs to be carved to become finest.' This string instrument player from the US seems to have a destined connection with Chinese traditional culture.

Later, he studied the Guzheng at NYU Shanghai and self-taught other Chinese traditional instruments, such as the Xiao and Zhongruan. Just as we marveled at how an American musician could show such extraordinary skills in Chinese traditional instruments, he surprised us once again by expressing his passion for electronic instruments or, more precisely, the electrification of traditional instruments. So, what exactly is it? Is it a corruption or betrayal of tradition? Can traditional instruments and electronic instruments coexist on the same stage? I hope that my interview with Yukes can answer these questions."

Yamaha DD-11 with Custom Patch Bay and Sound Storm Switch Mods.

video upload by Canned Sound

via this auction

"Rare 1990 stereo drum machine featuring a custom 'sound storm' switch which generates a deep, rumbling, soundscape which glitches and evolves until the unit is switched off. The 25 point patch bay modulates the onboard rhythms and sounds to generate an array of original effects and rhythmic variations. Making a single connection can dramatically alter the output but applying multiple connections produces an increasingly complex range of fractured, reversed, tonal, bit crushed, flanged, distorted, aliasing and delayed effects, arcade sounds and digital noise, alternative rhythmic patterns and additional accents. The five included patch cables can also be stacked for further sonic manipulation.

Features:
8 velocity sensitive drum pads.
100 preset rhythms.
10 drum kits.
1/4" stereo output.
2 x onboard speakers.
608 mm x 281 mm x 105 mm.
Takes a 9v power supply or batteries.

Yamaha PSS 795 AWM Vector Synth with Custom 30-Point Patch Matrix and Randomizer Switch

Note: Auction links are affiliate links for which the site may be compensated.
video upload by Canned Sound

"A presentation of this modified vintage keyboard demonstrating the use of the multi-timbral manual vector controller joystick in conjunction with the custom 30-point patch bay. This turns the unit into a generator of noise, bizarre soundscapes, a range of lo-fi ambient, aliasing, glitching and unison pads, corrupted rhythms and percussion."

via Canned Sound's Reverb Shop

"The Yamaha PSS 795 is a rare 1990 49-key digital keyboard which implements Advanced Wave Memory synthesis- the use of real world instrument and voice samples which are looped and/or blended with digitally generated sound. Four of the unit's onboard presets can be assigned to the vector controller- a joystick which allows the user to morph between each of these sounds. With the addition of the custom built 30-point patch bay, this adds up to one of the most remarkable, enigmatic and useful modified instruments Canned Sound has to offer. This feature unlocks an endless array of other-worldly soundscapes, bizarre loops, weird sample hybrids, drones, warped digital distortion, garbled and staccato FM sounds, ethereal effects, powerful unison patches, strange percussion hits and grinding bass tones. The unit also features a switch which triggers completely random streams of noise, sequences, effects and tones- another great option for sampling.

When utilising the patch matrix, each configuration of the five included stackable patch cables produces an often multitimbral range of sounds across the keyboard. The percussion pads and onboard rhythms are also affected. The capacity for the generation of unusual pads, noise and percussive hits is immense; this modified PSS 795 is a source of distinctly different sounds which any alternatively minded electronic producer will find inspiring. Demo to follow.

Specs:
61 mini keys.
ROM: 100 sounds, 50 rhythms.
8 percussion pads (46 percussion sounds + voiced numbers 1 - 4 are assignable to each).
4 patch vector controller (a user created movement sequence is writable in the 8 track sequencer).
Pitch bend wheel.
MIDI: In, Out, Thru.
Twin 3 watt speakers + headphone/AUX out.
Dimensions: 776 mm x 302 mm x 141 mm.
Weight: 4.5 kg."

"Rare 1993 MIDI drum machine with a custom 25 point patch bay. This modification generates an array of original sounds, effects 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 fractured, reversed, tonal, bit crushed, flanged, distorted, aliasing and delayed effects, 16-bit arcade sounds and digital noise, alternative rhythmic patterns and additional accents. The five included patch cables can also be stacked for further sonic manipulation.

The patch bay affects the 100 tempo adjustable onboard rhythms and tracks in addition to the pads and scraper which produce some great degraded digital effects and percussion hits.

Features:
8 velocity sensitive drum pads.
A 'scraper' ribbon controller for the performance of preset instruments, scratching and rolls.
100 preset rhythms with instrumental accompaniment options.
75 PCM percussion and effects sounds.

Speak and Glitch GND-1 circuit bent speech chip synthesizer

video upload by GND-1

"Here's a short promo for our new Speak& Glitch GND-1, a Circuit Bent Speech Chip Synthesizer unlike any other. Based on an accurate emulation of the speech chip inside the popular Speak and Spell game, the GND-1 pushes into previously impossible circuit bending realms letting you create loops, rhythms and synth sounds in totally new ways.

In addition to the stereo audio output from the synth chip, the MIDI-out rhythm generator on the GND-1 was driving a software 808 drum machine. But it can drive any midi compatible device, whether it's software, hardware, or even mechanical, both via USB midi and a dedicated 5-pin DIN connector.

See richardvanhoesel.com/gnd1 for more info.

p.s. the 'flickering' OLED display on the GND-1 in the video is just a video artifact."
