Me and a friend are building a laser harp modeled off of this project : http://makeprojects.com/Project/Laser-Harp/690/1
We have built the circuit to turn the note on/off when you shine a laser of the photocell. We have connected and wired the MIDI - USB interface through a 5PIN din connector. Using MIDIOX, as the Make project does, we get a note on signal when we shine a light on the photocell.
The trouble is that Ableton does not pick up the signal. Under preferences in the MIDI/Sync tab it sees our device and we can turn its track on/off. However, the MIDI indicator in the top right does not light up when we turn our note on/off.
I got my MIDI-USB interface from amazon here: http://www.amazon.com/MIDI-Cable-Converter-Music-Keyboar/dp/B001LJUVO4/ref=sr_1_2?ie=UTF8&qid=1329339607&sr=8-2
I never installed a driver for the USB-MIDI interface so that might be a problem. But would MIDIOX still pick up the signal?
Here is the MIDIsend Function
void SendMIDI(char cmd, char data1, char data2)
And here is where I call it:
SendMIDI(MIDICMD_NOTEON, i, 127);
Does anyone have any ideas?
Thanks a lot
EDIT: I am using the trial version of Ableton 8 on Windows Vista
