Arduino Sound Generation: Simple Keyboard Control

All sound is generated "purely" by an Arduino and a 6 bit R2R network.

The data entry slider selects a point within the waveshaping array / algorithm from which to start playing back and generating the sound. The keys are mapped to pitch.

doesn't the Arduino have built in DACs?

[littlescale]

@Biopharmer No - do you mean the PWM outputs?

[daneiellacey]

Nice!

is the midi going via Pure Data or some other PC software or is it interpreted directly by mr. arduino ? i would like to controll an arduino directly via midi if its possible?

[dtoliaferro]

I'd love to do this myself. Would you post the schematics and code?

[xasdrubalex]

@Biopharmer 10 bit internal dac, for analog output, just quite not sure you can work with it if you want to code in "Arduino".

Nice!

lol yeah sorry I did some research and discovered that it's not the same thing. Anyway, I just ordered 20 YM2608 chips and just put out a query for YM3016 DACs so I'm covered. Thanks anyway. I'm not making an actual product but I ordered 20 just to have backups. I know a lot about FM synthesis (I can program the hell out of my DX7) and I hope to do something cool with them. I'll post videos when I'm done.

Are you using midi to control the pitch on the Arduino?
