How to build a MIDI Rotator -Anyone

Using Arduino Audio
1

Hi

I am no programmer but after seeing this vid Arduino hardware hack for midi "enigma" machine. - YouTube I wonder if anyone here has the knowledge to build one ?

Any help would? be greatly appreciated !

Thanks

We've got a rotator demo for our Flexible MIDI Shield in the sample code section.

The QuadRAM shield: add 512 kilobytes of external RAM to your Arduino Mega/Mega2560

Is the code working just like in the video with Mr Kilgore ? ( with 4 additonal notes, Velocity scaling, Display, 1 pot, 3 buttons, Save option, etc etc) ?

Obviously the most complex thing about this project is the coding, but if this ( http://ruggedcircuits.com/AD130/Rotator.pde) is the complete code would it be possible for a noob like me to put it together ?

All help will be greatly appreciated.

Thanks !

Thanks for all the interest in the Arduino Midi Rotator hack shown in this video...Open Tuning Piano - YouTube

Unfortunately, I'm completely slammed at work these days, so I haven't had time to do any fun side projects like working on the rotator. My hope is that I'll be able to do a kickstarter project in the spring to produce a fully featured version for sale.

It may be my ignorance, but I refuse to be intimidated when working with new toys. Everyone has a different background, but with the Rotator.pde it sure looks like most of the leg work is done for you. I didn't see anything mentioning the LCD screen, but I'm sure there are PDEs for it.

I wasn't sure how difficult my MIDI to 8ch relay (to trigger standard 110v lamps) would be and the prototype took me minutes to build based on the junk I had lying around and code freely available around here. Looking back it was disappointing how little I had to curse to get it to work. :smiley:

I say jump in, have fun, expect to get a few black eyes along the way but don't let any of that stop you. I had a few years of electronics in college back when Clinton was in office which I've done a great job forgetting. Most of this is low level electronics and low level programming as well simply because someone else has already done the real work. Go for it!!
