Bendinator 4 - Circuit Bent Keyboard


This My Music World toy keyboard turned out a lot better than expected.

This is my first circuit bent keyboard to have a button called 'Egg' on it. This toy was bought for 99p in a charity shop by my son, and he also worked on it with me.

It had no controls when i got it, but I soon discovered it has loads and loads of hidden Demo songs which are activated by pressing the 'Egg' button then hitting a note. Pretty much each note fires off a different demo song, you can then mess them up with the other controls.

It has three Body contacts which work well, either touch the first two together for pitch wobble and dives, or touch the middle and third for harsh glitchy noises which are quite distorted.

It's pretty stable but does occasionally crash out to silence or holding a note, but the reset button is in a handy position.

It has a pitch mode with three settings, Mode A, Off (centre) and Mode B. Both modes have their own characteristics. Mode B turned full way will set the pitch so that notes are in concert pitch.

I also discovered there are a few extra sounds for the keyboard hidden on the board, so I added a push switch to toggle between them. The organ sounding one is good for pitching low, and sounding dirty and synthy.

The Bendinator 4 will probably go on sale in the near future on ebay.

It features :

Pitch Mode A/B
Pitch Control Pot
Body Contact for Pitch
Body Contact for Glitch
Easter Egg Button
Sounds Button
Reset Button
Output Jack
