For messing around the UDOO is fine, but totally unsuitable for incorporating in a manufactured audio product.  The Pd part is easy, the hardware is incredibly difficult.

I actually design Eurorack modules with Tiptop Audio as my day job, and can tell you that making a module using an advanced ARM chip is no easy task.  The Nebulae is a quick, dirty hack and it has many issues.  Design from the ground up around an A9 or similar chip requires very advanced tools (we pay a huge annual sum for high end layout software) and about 10 years of mixed signal PCB design experience.  Keeping the audio clean would take multiple revisions of a 10-12 layer board and you would need to make a Eurorack power supply that can handle the current of the digital parts.

It would take well into 6 figures to get a fully functional production ready prototype.

Looks great Chris, only thing that is weird is that it's a mic input not a line in that i get with the creative card currently. Everything else looks fancy. Would you like my address to send it? :-)


I am going to take the idea to our Innovation Hub at University of Florida and pitch the idea for the module, if it goes they might give me some seed funding --then i can explore some different cards/boards. A friend is lending his BeagleBone Black. Seriously if you want to throw in with  us i'll give you p0ints later :-)

Have you seen the UDOO board that have multi-core A9 CPUs, analog audio I/O and an arduino compatible microcontroller already?

Thank You all for your help so far
I have looked at Granola~, granita, my-grainer, dsis_munger and granny a port of Sakonda's famous Grain2.0 patch by bill orcutt, all of which failed because of the problem with compilation that Iohannes who is always so helpful mentions.

I have chosen to go with Martin's fabulous grainsamplerfx patch and modify it.
I have also found that ProcesoV8 and Johann's Monolog-x are wonderful candidates for a true pure data module.

I contacted Qu-bit Electronix with hopes of a complimentary board for my research but they are not in a position to help me. They make a wonderful product called Nebulae for Eurorack but it's just too expensive for my professor salary right now. I even asked if they had scratch and dent versions that they might let go of to no avail. It apparently takes pure data AND Csound code but it seems a little more bent towards Csound, but again this is just a quick observation.

I have successfully connected an arduino uno to 6 potentiometers and poll them with Hans' Arduino2pd patch
I am using a 1in/1out Creative Blaster go USB soundcard and Rpi see it and loads ALSA for it

I am experimenting now with getting the tty to be the same when i run RPI without Xwindows, i have created a few lines in the inittab to hopefully select that port each time but it's not working correctly. when i boot into X it polls and updates the Pots but when i only use commandline they are not talking to each other. The arduino is polling for sure but pd is not reacting.

Martin's patch with 6 very simple parameters sounds awesome

I would like to have  a RT Granular Patch working and then work backwrds from there because it will probably be the most processor intensive, I would like to create and awesome "Curtis Filter" like Dave Smith has released
http://www.davesmithinstruments.com/product/dsm01-curtis-filter-module/

Is there an example in OD that replicates such a Filter --2/4 pole resonant low-pass filter module?

The Nebulae uses samples and a microSD card for loading samples which i want to try to avoid, i would like to keep everything RT.

what do you all think?
Please make suggestions of patches you think might be worth testing.
I would like to manufacture the boards and design the prototype this summer since i cannot afford to direct my research to the Nebulae. This Fall i will have 30 graduate students coding with me so we will have ALOT to offer.

Patrick

you cannot use a binary for i386 or amd64 on a Raspberry Pi, which has
an arm processor.
you need to have a binary compiled esp. for this achitecture (read:
compile it yourself).
