I did send a request to my dealer. At the moment I tend to buy a 9632
and if I should switch the mobo one day, I perhaps have to replace it by
the AIO, anyway, the 9632 is less expensive. But I'm undecided.

I guess I'll start with just AI4S-192 AIO and AO4S-192 AIO for home
recording. If I should need more channels I'll order a cheap ADAT device
at another time.
More channels might be needed to do rehearsal room recordings, with
cheap microphones, hence the sound quality is less important, "live"
music has an advantage regarding to the feeling compared with home
recording, just for home recording I wish to get the most near
professional sound that is possible by my equipment, but at home I don't
need much channels. 2 for the stereo sum and some to loop in a 19"
reverb or to record drum sounds from a drum module by separated channels
at the same time.

Me too.

Thank you,
