The Motu is $1000. The Presonus is $500. What about getting 8x 2-channel USB soundcards? The Griffin iMic is a 2x2 and is $40. So 8x would be $320.

If you look around, you can find 2ch USB audio adapters for $20/each, $10/each, even $2/each. For that kind of money you could purchase a few and evaluate them in terms of quality, or maybe read up on what chip they use and read reviews.

I'm pretty sure Pd supports multiple audio adapters, but have not tested this.

Please post your results, as I would like to get into ambisonics as well and be able to drive 8x or more speakers. But I don't want to spend $1000!
