Very cool video!

I Just bought one of these :)

Con you help me with the mods?

I opened, but all i found is 3 trimmer potentiometer. Bias, Fine pitch and some kind of vibrato control, but even is i set it to maximum the vibrato is barely noticeable. so where do i have to solder pots for x-treme Pitch and vibrato?

also some of the key contact not perfect, how should i clean them?

@NemuiKuma Sorry i do not know how to fix the problem with the keys. i have 2 not working keys too ... i don´t know exactly what i have done to this keyboard , but i will open it up soon and have a closer look and tell it to you.

[BaumDerProllige]

@Pingellotto Thanks for the comment , but i can not speak italian...sorry.

But i think you want to know how its done. Its pretty simple. Open the keyboard , and connect some soldered points together :). This keyboard is very very simple in the inside.

I never thought of selling my Devices ... They are like a little piece of my heart ;) But it is a pity that they get dusty because am too occupied with building new stuff :) I Think soon i must sell some stuff.

Sorry at the moment i do not have any drum or mixer toys. BUT i have an unbent Yamaha PSS 140 with seperate Drum Pads. It would be a pleasure for me to bend it for you OR if u want to bend it i can send it stock :) It´s size is like a PC Keyboard.and a good example is the s-cat (0043)
