What confuses a lot of people is the way the ASIO input list is shown for some audio interfaces.
Tascam mic 1 Left is channel ( mic ) 1
Tascam mic 1 Right is channel 2 and so on.
Tascam Mic 1 Stereo is a stereo recording of both ch 1 and 2.
Only odd numbers are shown but the "right" side is the even numbered channel. Example if you plug guitar into input 10, then you select "Tascam instrument 9 Right."..You'll figure it out.
It will record 8 XLR inputs into 8 tracks.
Then there are 2 Instrument jacks, And on the back there are 4 line level, and then the SPDIF and the MIDI.
You can record 17 things at once if you max it out.
The drivers where sketchy with 32 bit, The 64 bit drivers have worked without any issue for me for a couple of years now. That's on any computer system too. Only negitive is the Round Trip Latency is about 7-10 MS so not good enough for guitar rig type work.
