derek, thank you for your answer, looks interesting and I will probably use it for another piece. but for this project 60s is not enough. there will be several tracks and all together at least 20 minutes, which would be ~20MB at 8khz. maybe it is possible to hook together a bunch of chips, although I would probably not be able to reprogram them. so what would be the next size? I somehow like the idea of running pd on a very small thingie. it is not a must, of course. marius.
