Wow. Glad I logged in here. I check this forum about once every 6 months or so...
I asked a similar question a long time ago and people basically said "No." There isn't much help out there on the internet for this one. So as I have been learning (very slow process) I have been making some really basic tutorials and posting them on Freestompboxes.org under their DSP section.
Here is the first thread I started: http://freestompboxes.org/viewtopic.php?f=29&t=15620. It is basically a list of helpful documents and tutorials that I have found on the net since I started. Some of them were extremely helpful to me!
Then I made 3 short tutorials:
Hopefully these are helpful to you or anyone else who comes across them. I am working on a 4th tutorial, but my pedal seems to have malfunctioned today. So I'll have to look into it more when I have some time. If you have any questions, please post them over at Freestompboxes.org as I don't come here very often, but I check that forum on a fairly regular basis. Also, I am not very experienced at this so I might not be too helpful at answering questions, but I'll try my best.
Best of luck!
Note: all of my tutorials are in Assembly because everyone on the net says that's the way to go. Its not as hard as it seems. You will just have to put some time into it.
