Red Casio SA-2

At last I got my own Red Casio SA-2, a bit rarer than the black ones and supercool!

Hing Hon Ek-001 'Vortex'

3 knob Hing Hon EK-001 'Vortex', listen here.  click here to check out all the other 'Vortex' keyboards I have made.

Yamaha PSS-6

Circuit Bent Yamaha PSS-6, features Starve pot, Loop switch, and 2 Glitch buttons, plus a 1/4 inch output round the back.  Quite similar to the famous casio sa-2/sa-5 Aleatrons but with a lot more control over the sound and less crashing.  Probably one of the craziest sounding keyboards I have done ; )  Mentalism here.

Casio EP-10 (Muppet Babies!)

Got this the other day, a Casio EP-10 Muppet Babies keyboard, closely related to the famous Casio VL-Tone series of keyboards.  Only 4 sounds, but they are very analogue sounding.  More info here at the brilliant Tablehooters website.

Yo! The first ever Rap keyboard!

Picked up this Casio Rapman keyboard from a local car boot sale.  Some nice sounds and a 'voice effector' which pitch shifts your voice when used with the included microphone.  I doubt if I will be re-selling this, my 4 year old son loves it! ; )

Kawasaki keyboard

Circuit Bent Kawasaki keyboard with pitch control knob and switchable light dependent resistor (housed in a nice chrome bezel).  Often it's hard to find the pitch control bend on these keyboards but not on this one ; ) Soundclip here.

Circuit Bent Yamaha PSS-130

Really like this Bent Yamaha PSS-130!

Megcos keyboard/drum machine

Simple keyboard/drum machine with downwards pitch control.  This is one of the first 'toys' I have seen with surface mount components instead of the usual larger resistors/transistors/capacitors etc, making it a bit fiddly to solder!  Audio here.

Super Concert Animal Keyboard v2

2nd version of the Super Concert animal keyboard I have done.  Downwards pitch control, glitchloop threshold control with momentary on button, reset button, and light dependent resistor with on/off switch. Mayhem here.

Phonics Keyboard

The original toy is basically an alphabet desk with a keyboard attatched!  The bends are 'always on' and consist of a pitch knob and a light dependent resistor, the more light the lower the pitch.  Works best in a darkened environment.  In a light environment no sounds are generated until you cover the light dependent resistor.  Audio here.

1 knob Hing Hon EK-001 'Vortex'

Minimal 1 knob version of the 'Vortex' Hing Hon EK-001 modification.  Once again a totally different layout to the innards of this version of the classic analog square wave synth, only one control needed to take this toy keyboard into a very dark place!  Audio here.

Green Keyboard

Green keyboard with Pitch control and distort switch.  Capable of some pretty agresssive tones and drones.  Audio here.

Hing Hon Ek-001 'Vortex' SE

The latest in a long line of Hing Hon EK-001 'Vortex' keyboards.  I keep on picking up these keyboards with different insides every time so each one turns out different.  Controls added are the 2 knob time vortex section (with crash protection preset pots) and an overall pitch control.  Had to remove the internal speaker to fit the controls in, and added a 1/4 inch audio output. The bends make this version is a LOT bassier than others I have bent in the past.  Audio here.

Super Concert Animal Keyboard

Insane animal sound keyboard with 2 pitch controls, and a 'droneloop' button with its own threshold control. Things start getting mental when the light dependent resistor is switched on, more light equals more extreme downwards pitch shifting. Mayhem here.

Sing and Play keyboard.

Keyboard with added pitch control for mental pitched down drones. The keyboard lights up while you play! Audio here.

'Vortex' version 3.1

A new rave look to this version of the 'Vortex', Audio here.

Orange Keyboard

Orange keyboard with microphone.  I have added a pitch control and a 'filter' control.  Makes nice pitched down drones that you can play with the keyboard, the filter control gradually thins out the sound and changes the decay and pitch envelopes altering the timbre.  Mp3 here.

DSI keyboard

Some nice tones from this keyboard, with added pitch control and decimation body contacts. Audio example here

'Vortex' version 3

More 'Vortex' goodness to be had from this keyboard which seems like a simpler version of the EK-001, sounds very analogue! Added pitch control and 'time vortex' section with on/off switches.  10 minutes of audio here.

Casio SA-2 Aleatron

A Casio SA-2 Aleatron based on Reed Ghazala's original design. Great for complete randomness! Audio here.
