Emu XL-7 & MP-7 User's Group

Hello,

yes, I know I can gain each layer it just would be very frustrating
to do it for 512 presets. I'm full :))))

Anyway, -8 dB is not so worse, and as Aaron suggested I will
use gaining outside the box when needed through the FF 800,
probably only in the recording stage.


Regards,

    Zsolt

You probably already know about this, but don't forget that you have
up to 10dB of gain available in each preset layer as well (if it's not
already maxed).

Useful info about the digital volume control...
