a MIDI project - wireless

Are you looking for the circuit to read the sensors, or just something to transmit?

Radiotronix makes some el-cheapo xmit and recv devices. Or, you could go with infarred linkups.

I've been gearing up to take on a new hobby project, building a wireless MIDI controller.

I've done a fair bit of research and I am pretty straight on what parts I need for the task and so on.

The one roadblock I've hit is making the setup wireless. The options I've explored are mainly Bluetooth and RF with the latter looking to be more promising.

Problem is, I'm so new to this that I'm not certain what to do next. I'm aware of how to program a PIC chip to read output from a sensor, and in turn translate that data and send it over a serial MIDI connection to my computer to have it trigger the said note.

I'm hoping that someone could give me some idea(s) as to how to accomplish this wirelessly? What parts I will need, what a basic schematic might look like?

My device will most likely have 12-14 buttons that will need to send a note a controller change upon being pressed. Velocity register through a piezo or FSR is also likely.

I've done some searching around already but couldent find anything in practice, mostly just theroy of how it "should" work.

Many thanks in advance-

note

There are two major issues as I see it. One is MIDI, formatting the midi status and data bytes properly then sending them through a UART to develop the required 31Kb/s signals also properly formatted. The second is the RF link both transmit and receive and turning the signals back into MIDI then linking to the Computer through the USB or other port. Each has its own technologies and potential problems. They should be tackled separately. First get the MIDI system working over wire then worry about how to link by RF, infared or other scheme. I'm a little concerned because you said: "12-14 buttons that will need to send a note a controller change upon being pressed." I don't know what this means. Control Change, Program Change, Note On and Note Off commands are separate and are defined by the status bytes including the MIDI channel to be addressed. Note values, velocities, controller values, etc. are data bytes referenced by the status bytes. Maybe you know how all of this works , but even if you do, get a book on the subject and visit the MIDI web site for the MIDI specs. There is a lot to MIDI and to get it working properly will take some effort. I wish you luck in your endeavor, you'll learn alot if you tackle it. Bob
