@dakota Nice!!!

Now I updated tutorial to compile 0.51-0 Pd version!

Yep.. You can use comport. It be posible comunicate Pd and arduino.

Drymonitis have nice documentation to do that.

The tutorial "Arduino for PD'ers" is a good start: http://drymonitis.me/code/

He has a excelent book "Digital Electronics for Musicians" if you are interested you can try it to.

See Else library for pitch shifter objects... autotune I don't know.

@RetroMaximus what external are you using?

I have a pd 0.49 (self compiled) and wiring pi working in a project with Raspbian Stretch in RPi2 3B+.. But to make wiring Pi work well you will need to run puredata in root mode..

Works like a charm..!

Thanks @jancsika ! At this moment I'm parsing xml files in Python scripts. But I will try purrdata again to..

Great @nicnut Well I was working in another image.. Even smaller... With Pd 0.49 and Purr data pre installed.. I already did not tried to use midi in these... But we can start it and post another image with these hacks out of the box!

You can't use 32 bit version in your system? Maybe it works...

I found in William Brent website the source code, you can try open a issue and try to compile yourself a 64bit version of [convolve~] with wbrent help.

Good luck!

@nicnut I tested this Raspian with Pd and Purr Data installed image. I tested it in my RPi2 and it should work with SD Cards bigger than 8 Gb.

I'm crossing my fingers for you!!! Now it is my last chance to help you! hehehehe

I don't know what happened... Try it... I make a fresh Raspbian with Pd and Purr data installed on it, I will share it when upload ends. Perhaps it can work.
