Well, there are valid technical reasons for 192kHz. Mainly the freedom to
use less aggressive reconstruction and anti-aliasing filters in you sampling
hardware.

maaayby. I understand what you are saying. But respectfully, don't like it
(marketing based decisions).
Also I feel that GIMPI will be cleanly designed, and will not be difficult
to convert to 64 bits later anyhow.
Best Regards,
