I'm using the Akai EIE 16 bit
Uh... okay well I had to actually go look that up for ya to found out how many outputs it had (apparently it's a 4 in/4 out device but can be daisy chained).
You are not going to get anywhere near 64 analog output channels (unless maybe you have a bunch of them chained together... and even then I doubt it).
1 hardware output on the device = 1 hardware output in Sonar
You are limited to what your interface can physically send/receive (aside from maybe internal loopback stuff).
If this is a purely MIDI question... that's different but selecting all the MIDI ports available on the device will make them available to Sonar and anything else hooked up to the device.
Soooooo.... more info is definitely needed here IF you have some wacky setup that could possibly allow for 64+ hardware outputs from that device.
Cheers.
