[sdiy] Midi to clock with shuffle

[Tom Adam]

I have a patch to simulate a shuffle effect that I use a lot.
The patch works as follows: The patch uses a VC LFO, sequencer and sub 
octave generator.
The LFO out is send to a MFOS sequencer and the sub octave generator. 
The output of the sub octave generator is send back to the FM input of 
the LFO. I play with the FM depth pot on the LFO a lot to get the timing 
right. I think Thomas White has a vid online somewhere to demonstrate 
this patch.

Anyway, my question now is how to sync this patch to my other midi gear.
I got an arduino that's generating an analog clock out of a midi stream. 
I programmed the arduino to get a basic shuffle pattern out. This is 
kind of working.  It just don't get the same feel as when using the 
analog solution due to the static behaviour of the math in the code.
So now I'm looking for an analog way to change the 'distance' between 
the pulses of the arduino out. I'm guessing some kind of PWM as a stand 
alone module. Does anybody have an idea on how to do this?

Now that I'm writing this I'm considering adding a 'shuffle' pot on the 
arduino, but I need to get the math right first.

I hope this explanation/question make sense. Thanks!
