PICAXE & Roland sp404 MIDI controller

[kam]

Hey Everyone,

I was wondering if anyone's ever dealt with a ROLAND SP-404 MIDI sampler.

A friend has asked me to build a remote control for him so that he can play his sound effects without standing next to his sampler.

The device has a MIDI IN. so i'm assuming that there's a way to communicate with it via PICAXE and get some bits through to tell it to play a certain sound.

I'm new to MIDI and I don't know much about it.

Any help would be greatly appreciated.

Thanks

Kam

MIDI is just a 31,250 baud serial signal through some simple driver hardware ( two resistors, 5-pin DIN socket ) so it should work. The X1's and X2's will allow 31,250 baud and it's also possible using an 18X but more complicated ( I'd use an X1 or X2 ).

Beyond that, it should just be a question of knowing what 'MIDI commands' to send for what he wants to do and developing the PICAXE hardware to trigger sending those commands on button push or whatever.
