OT: building a simple midi interface?
« on: Feb 21st, 2005, 3:07am » |

Hello all
This question might be a little off topic...
I want to build a small knob - a potentiometer - that would send midi signal like a midi expression pedal - that would be connected to the computer feeding processing + a synth with information.
Does anyone know where can I find schematics for building something like this? A circuit where the input is a potentiometer and the output a midi modulation?
I haven't found a simple+cheap commercial solution available....
thanks (and sorry for being off topic, but this can be relevant to others...)

Try the MidiTron, I bought one for something recently
http://eroktronix.com/
20 terminals for input and output. Simply wire up your potentiometer and plug into power, signal, ground on the MidiTron. Plug on a 5v battery and set-up analogue input on the MidiTron, turn the pot and you'll get a value of 0-127 going in via your midi connection (you need to buy cables and usb, or use joystick port).
Theres a lot of information online about building your own midi interface.

Hi,
Maybe now already outdated for your request but, a less expensive solution (but some hours of soldering):
http://www.ucapps.de
...search for midibox16
16 inputs analog....
Build one myself...but not tested it in processing..although it works great with Max/MSP.
Or if you want a smaller version...pm me!
I can probably program some PIC for you..
greet,
Erik
