Hello all,
I am in the process of developing a Arduino shield that takes the Auduino to a whole new level. I am going to fabricate 5 PCB's. Im interested in having a couple long term forum users beta test the shield kit. The testers will get a good discount compared to the actual product. There will be two demo programs, a granular synth with MIDI IN support, and a midi software controller. If you are interested please PM me. The official kit should be available in 2-3 months. http://picasaweb.google.com/HELLOwhereiseveryone/SynthProject?authkey=pe-DLGABWCU#5287999304072757506
Features:
Audio output jack
MIDI IN jack
MIDI OUT (using USB and Processing Java Applet.)
6 Pots
3 status LEDs
2 SPDT switches (NOT IMPLEMENTED YET)
I'm everything but a long term forum member ( as a matter of fact I only registered today after lurking a couple of weeks) but I must say that this shield looks very nice. Is this the one you mentioned in your arduino project blog?
I've been experimenting a bit with the auduino granular synth myself. I learned about the arduino as I was googling for a way to retrofit a bugbrand Workshop Oscilator Machine with MIDI. I will definitely follow the evolution of this project.
Edit: I noticed that this design only mentions a MIDI IN where your blog mentioned a MIDI OUT, would it be possible to have both? This would make the shield more versatile imo.
To pt3r: There is no MIDI OUT jack, but using a processing applet and some Arduino code, you can use the shield as a midi controller. This setup will be a demo program. If you think that there will be enogh people interested in a actual MIDI OUT jack, I can add one. Thanks for catching this, I updated the my first post.
Thanks
To Peter Knight: Hello,
It would be great if you could help me inplement an idea. I am not the greatest coder, so Im getting my friend to Write the demo programs. With this shield setup,there will be two unused pots. I am interested in what you think would be a cool function to add to the board. I was think 2 second volume envelopes that would each control one oscillator. How hard would this be to implement?
Thanks
To all: I will continue to add all updates I make to the shield on this thread and my blog.

Arduino has 6 analogue ins. Auduino currently uses five of them. One spare at the moment - Analog 5.

Anything is possible. The main constraints you have are:
Does it sound good? Its important to not go too far down the design route until you know something is worth doing. Synthesisers are tricky to predict. Try things out as you go.
Timing constraints. The sample calculating algorithm triggers every 32µs, and takes around 16µs to run. Implementing MIDI reception might be a problem, as the Arduino serial routines have a lot of overhead.
Pin constraints - the first one you'll hit is only having 1 free analogue in.
I may be able to help with small things, but I've got a new project that's taking a lot of my time at the moment. If you want something done swiftly, I'd dive into the code and have a poke around. It's edu-ma-cational!
