Title: DIY MIDI controller
Post by: parricide on November 26, 2012, 11:03:52 AM
anybody got any advice on a board to build a midi controller with? i obviously need it as cheap as possible.
all i need is buttons to trigger ableton live clips (a simplified launchpad). not sure how many buttons yet, but maybe about 16 buttons minimum.

thanks

Give this a look-

http://store.highlyliquid.com/collections/midi-controllers/products/midi-cpu (http://store.highlyliquid.com/collections/midi-controllers/products/midi-cpu)

It's not uber cheap, but it has 24 terminals to hook switches/potentiometers/encoders up to.

The configuration for the terminals is very flexible/customizable.

don't doepfer do something along those lines? It'd probably be more expensive, but you won't get stung for customs fees etc bringing it into the UK.

EDIT: Even better, this polish site has some good stuff

I've bought various interfaces from them and they are excellent. The tiny MINICV midi to cv converters are smaller than  a 10p coin!

if you decide to get it, I know the firmware/configuration inside and out on that thing..  it's quite a capable little unit.



Thanks for posting the poilsh link CB.. lotsa cool stuff on there.

ok here here a project i been thinking about for about 6 months which i will do when i have more time i have a old korg SG-1D keyboard which has a lot of problems but being a 12 bit at best was only used as a controller so  i want to make a midi controller using the keyboard and case and add  pots  + switchs and use it with the draw i am using to controll vst instruments

I posted an answer at the MIDI CPU forum..

You'll need to use up 19 CT's/Ports on the 24 CT/Port controller to create an 88 note matrix, if Korg was sane and did 8 Data Lines and 11 Select lines.  
That gives you 5 remaining CT's to hook up pots n  switches.
So you'll easily need another MIDICPU to get the extra 16 pots and 8 switches.. or combination of..  you can have a max of 16 pots per CPU board, no more than that.

We'd need the schematics and/or pics of the keyboard wirinig/PCB to determine it's matrix setup and show how to hook it up to the CPU

To be honest i don't really remember, though it was probably about a week from when it was shipped until it arrived.

I know that Roman, who runs the place, is working on a few other things at the moment and a couple of items are out of stock until the new year, but he's usually pretty good at answering emails
