Thanks for the reply. So, would FFT analysis allow the use of multiple triangle controllers on two channels? Or, even a single i/o audio channel--say you have 16 frequency bands, and the natural harmonics of a 512-sample sine wave (for perfect FFT analysis) and you just ran the same channel through all 16 triangles (8 pitches). Wouldn't you be able to split the signal apart using an FFT and judge the power of each individual band? I know that there would be a small frequency lag, but reducing the buffer size to 256 or 128 (or increasing sampling rate to 88.2kHz) would minimize the lag, albeit at the cost of CPU resources.
I'm particularly interested in the continuous-controller approach, primarily because my goal is to get Just Intonation on a much finer scale than any sort of existing MIDI controller. Also, I like how the reaction time is around a millisecond. Any sort of problems with too much skin of the finger touching aren't really an issue (any more than they are on the violin, anyway). Thanks again for your thoughts.
Oh, I saw that it was buried in the poly~. Sorry about that--I might try my hand at a 4x4, though. Has anyone else tried making one of these?
So, I've got a PreSonus FireStudio that I don't mind devoting 4 channels to (some of the time), but I don't really want to devote all 8. Also, does it take 8x8, i/o or 8 in and 2 out? I'm asking because I want to do some distribution where I'd need just one input and four outputs, so I'm wondering if this could be like a complement to that.
One more question: if the 8 channels in are really, totally necessary, do you have any ideas of a good 8-channel cable-to-ADAT Lightpipe interface that I could use? What kind of preamps are necessary to get a good response? I don't want to spend the time making a lame instrument, but I also don't want to spend $1,000 on an 8-channel fancy mic preamp just to have it be basically useless.
All right, lots of text, but the basic question is whether the 8 inputs are totally necessary for this.
