I am getting 8 channels over USB+ by the ESI Gigaport!

Just bought this one 2nd hand for E50. On the road you can listen to 8 Channels by using headphone right (all chnls). The left out is stereo L&R.

Great find! Thank you, Roland!

One caveat to anyone who's interested in this converter, the new models of the ESI Gigaport use USB-C so they are not compatible, even if you use a cable adapter. As Roland mentioned, he found an older model on the used market that was based on regular USB.

Nice! I have 2 of them for installations and immersive theatre. I've been using them with RaspbrryPi and PureData. Never thought of trying out them with Kyma. I believe they are the best affordable solution for multichannel USB-sound as well.

Nice discovery. What makes it different to other USB cards that only give 2 with Kyma?

The firmware in any USB audio interface specifies the word-size and format. This one's device descriptor specifies 16-bit words for 8-channels at 44.1 kHz as an option, which is compatible with the Paca(rana) USB input. Most multichannel USB converters do not specify a 16-bit word option so their required bandwidth is too high.

"This one's device descriptor specifies 16-bit words for 8-channels at 44.1 kHz as an option" - thanks SSC!
