Cool anyway thanks for you help doc, i recon im about ready to get the bits i need to put this together. So il just go thrugh what i recon im going to put together and if anyone can see any problems with what i want to do a shout would be cool. So i need a core, and a DIN and DOUT module, and probibly a lcd for convinince. Then i conect up the matrix off the keypad to the dout and din module. and then join everything up to the core? On the concetion diagram off the mios downloads page, there is a diode after each switch on every colloumn, is it possible to have just one diode on the end of each row thus insted of like this cos if not im going to have to hack the pad apart witch will be horrible. And witch way round is best to conect it? 8 Columns and 5 Rows or 5 Columns and 8 Rows. Well thanks if anyone has anything to say on this -ed

duh thanks, i should have seen the example on the downloads page. Its a 5 x 8 matrix i think, but i recon it will be cool to play about with. I saw a alesis drum pad with similar buttons on it once, obviously it wont be the same without velocity but still cool to play about with. and for changing patterns and settings and stuff on synths and squencers it will be ideal, and cos it is absoultly tiny (about a 3rd of a PC keyboard) it can almost fit in my pocket

im thinking of trying to build a zx spectrum that i have lyeing around into a midi box. It has a membrane keypad, and i figure i may be able to conect it up to some DIN modules or something. But im not sure exactly, how this keypad works. So if anyone has any info on how possible this would be to do that would be excelent. Anhow this is a scan of the inside of the keypad, do i need to put together some sort of multiplexer to conect the inputs from the keys? sorry i guess i sound quite stupid, but thanks anyone who reads this. -ed
