This is a glitch/random bend by Finlay Shakespeare  http://www.futuresoundsystems.co.nr .
The mod was originally done on the casio sa1 but it should work with all the sa-serie.

Here is another random/glitch mod I found in a couple of forums:

The Yamaha PSS 390 is the “toy keyboard” claimed to have the better and best sounding FM synth engine in the toy range.
It has 100 tones that can be widely modified with the tone controls, instead of button +/- it features sliders to edit the synth parameters.
The only lack is the midi control that however  can be added by retrofit.
It can be seen in action in the videos of the band “the Apparat Organ Quartet”.

Doing some circuit bending on my casio keyboards  I collected some useful schematics to “safe-bend” the casio sa serie (sa 1 2 5 8 10 20 etc).
The main mod is the one from Casperelectronics that adds interesting bends as the “glitch/randomizer” , “feedback” , “5th add”, “pitch shift” and the classic “power crash”.

In the forum www.circuitbenders.co.uk I found another scheme based on the casper mod but with some adds.

Nanoloop is a good alternative to LSDJ as a tool for making 8bit music on gameboys, even if it’s a sort of alter ego of Lsdj.
The sw is intended as a synth/sequencer  with a really carachteristic layout.
It uses a grid of 16 step (4 x 4) and in every step there are two marks, as it shows various pages (pitch, envelope, modulations..), the position of the marks shows the value in a graphical way, no numbers.
The particular sequencer force the composition in a more electronic and particular way than LSDJ, that use a classic workflow, and the absence of sample player force the user to build rhythms using the synth parts as noise or wave.
I omitted to say that the sound engine is alway the same (2 x pulse, wave , noise like on every gameboy).
At first Nanoloop can seem a little tricky sw , but after a while I found it really “open on the sound creation” and useful to create loops but also experimental sounds.
The one I described is Nanoloop vers 1.x , the one for the old gameboys, but exist a a vers 2.x too that runs on GB Advance and DS/DS lite, that has a more complex structure and more synthesis potential as FM.

“Need a quick and dirty sequencer, or a fun and simple instrument with which to noodle? Bliptronic 5000 is here!”

The Bliptronic 5000  could be an interesting “music toy” , for 8bit,glitch or bending.
I think  I’ll get it!!

Amazing…

Commodore 64

The SID is a synthetizer chip built to give a “voice” to the classic home computer Commodore 64.
The sounds and music capabilities of the Commodore 64 were really ahead at that time, and everyone of us remember the tunes of tons of games played on the C64.

The SID (MOS6581)

The sound  capabilities of the C64 were really appreciated by the demoscene movement during the 80s and early 90s, and even experimental electronic musician incorporated that sound in their compositions.

In the 90s a little synth manufacture started their businness building the first SID based synth, the SidStation.
The sidstation uses a single chip as voice generator.
When it first came out there was little interest in the machine, it was priced and sounded like a C64…
When people started hearing the sidstation sounds in pop or dance tracks understood the power of this little chip…

Today the Sidstation is a priced collectable piece of gear as they were made on a limited number (under 1000 units) and are out of production from years.
So the alternatives to get a midi controllable SID are a few…

• MIDIBOX SID (a Sidstation-like diy synth)
• HARDSID (a “sid engine” controllable thru usb)
• MIDIBOX WILBA (an evolution over the classic Midibox)
• MSSIAH (a midi controllable program on cartridge for the C64)

Casio SK5

The Casio SK serie started with the SK-1 (one of the best selling toy keyboard of the period) and the target was a the consumer market.
The little sampler was technically far from the professional counterpart like Emu or Akai, it was just a toy with a tiny memory of few seconds and no memory retain.
Soon after the SK1 the SK5 followed.
The sK5 was an upgraded version of the SK1 with more sampling time, the capability to sample 4 sounds and to retain the sound in memory even with the power swithed off (if the keyboard run on batteries).
The sampling specifics were the same as the SK1 (8bit- 9,38KHz) quite low even for the time, and apart from didattic use by children, the sk seemed at that time just a toy.

The cheap prices of second hads SK and the “Anti Theory” of Reed Ghazala made the fame of the little sk grow.
The interesting circuit bending capabilities of this instruments made them popular between the circuit bending community as a “must have” together with the  “Speak & Spell”.

The Antitheory statement , by Reed Ghazala, is that you don’t have to know anything about electronics to do circuitbending.
A circuitbend is like an energy flow thru shortcircuits…
A circuit is not designed to have shortcircuits , so you have to “think different” !

The SK5 is now a well known and is now considered  a “real instrument” , not just a toy, after many more or less inportant, famous or trendy artists used it.
Just to name a few…Autechre, Bjork, Portished, Nine Inch Nails , Blur, Aphex Twin, but the list is long…

The heart of the instrument is a 8 bit sampler with a very lo-fi sound and 4 voice poly.
It can samples 4 sounds and play them together with the rubber pads or with the keyboard.
The performance can be registered with the onboard sequencer, with no quantization (you cannot correct the timing).
Every sample can be edited with the “envelope shapes” that adds crescendo, sustain, vibratos etc., can be looped or reversed .
The sample memory can retain the samples if the keyboard has batteries.
There is also the possibility to choose a “long sample” time (it occupies 2 samples slots) to sample a loop for example.

The strenght of this keyboard is without any doubt the sound, because the samples are totally mangled and they sound really different , like pixelated…
This is really great for lo-fi sounds.
The second point is that the SK 5 is an easy instrument to circuit bend and the mods add a great variety of  “tools” to shape new sounds with the twist of a knob or a simple switch, a variation not known, an aleatoric change, that’s why Ghazala called his mods projects “aleatrons”.

Hello!
I’m back home from holidays, I’ve spent some really nice time playing with the Nintendo DS on the seaside.
So in the next days I’m going to share some tips & tricks about the DS music applications, they are really interesting!

This is a famous Daft Punk song played by a friend of mine (Gattobus), using only a Nintendo DS lite with Korg DS10 (software) and a Korg Microkorg (reverse keys).
Simply amazing!!!
