was wondering whats a good software synthesizer?
we're building a laser harp with 10 laser beams.
we're trying to interface the arduino board to Fruity Loops (software synthesizer), but we're having trouble communicating it.
im hoping somebody can show me a way 
thank you!
We need more details
What have you tried until now ?
Are you sending MIDI or what ?
hardware / schematics?
Arduino code ?
There's enough CPU time on the Arduino to synthesise three voices directly and send the output to a PWM pin. We did this for a musical synthesiser attached to a bicycle wheel, for Dorkbot Bristol.The project resource page is here: Google Code Archive - Long-term storage for Google Code Project Hosting.
