I was unhappy with the MOTU 828 because it seemed to use up a lot of cpu - otherwise very good. BUT on the subject of USB : Because the mini jack out on my laptop is fucked and i wanted to try and find a simple way of getting sound out I got hold of an iMic. Now this is actually fine for getting sound out BUT : when running patched where I'm sampling via AudioIn a lot of the output is distorted. The same patch using a soundfile is ok. This happens nearly all the time and regardless of whether I use built in input or iMic input. Anyone know why ? Anyone know how to replace the built in sound out mini jack without sending the machine back to Apple ? Anyone know how to take the hard disk out of a G3 firewire laptop and put it in another - I want to swap hard disks between 2 laptops but cant seem to unattatch the hard disk from its wiring.

This example spawns voices with an infinite sustain, but the maxVoices = 3 causes the envelopes to get stolen. You must use an EnvGen for maxVoices to work.

I've sent a detailed account of this phenomenon to Griffin but haven't heard anything back. For kicks, I cc-ed the people who make the low-latency USB driver that works with the iMic and other products, called Propagamma, I think, at http://usb-audio.com/. Specifically, the input and output sample rates, when both are set to 44.1 KHZ, differ by 135 samples in 120 seconds. This is completely repeatable and is independent of the actual latency (which varies around approximately 2800 samples on my set-up). It seems to me that eventually, there's got to be a buffer under-or overflow at some point. In any case, I can't use the iMic for the system frequency response measurements that I had hoped for. Incidentally, my testing never involved SC, but I thought some of you might be interested. I'll post the details of my tests if anyone is interested.
