help for beginner please....
« on: December 01, 2014, 07:06:25 PM »

Hi guys.

Complete noob here. so please forgive me sounding a bit stupid...

I have purchased my first toy to bend... Perhaps it's a bit much for an absolute beginner but i was the only thing i could find in the charity shops..

Basically i've opened it up and got to the PCB..

I have a loop running  then i start touching solder points with the small alligator clips i have waiting to find some weird sounds..

Now after playing around for half hour i'm yet to find anything really happening..

When i play around with the smaller board in the pic i just tend to get notes being triggered, which kind of makes sense as thats where the keys are..

I havent found any weird distorted sounds or effects as of yet..... Has this keyboard even got the capability of creating those kind of sounds...??

Is this just a case of more trial and error or is there somewhere specific on the board i should be looking???

As i say complete noob here, so please forgive me sounding a bit stupid... But any advice would be much appreciated...

I've attached photos of the boards etc...

Thanks  :)

EDIT: i cant seem to upload pics of it.. Keeps timing out :/

Its a Cyber piano like this one in the link http://majormusicbargains.com/musical-keyboards/m-z3r0-circuit-bent-kawasaki-cyber-piano/

I've just assigned a bit more space to the attachments allocation on the server, so you should be able to upload pictures now, although they need to be under 100K each/

What keyboard is it? Unfortunately not everything will do anything decent.

try limiting the battery and look for the 'brain' (an IC chip/black blob etc)

Also if there's anything in particular that really good for distortion that anyone could recommend that would be cool too.

Thanks guys :)

well, there will probably be a pitch resistor in there by the sound of it, but i've never modded that particular model before.
It looks like theres a pitch LFO built into that as well

you won't find an LFO in there. You'd need to build your own and use it to control the pitch.
