Here are links to the Tech 21 Midi Mouse and Midi Moose manuals:
Hopefully they are useful to somebody. Also, as far as I know, Tech 21 has only made one MIDI equipped product which is the PSA 1.1. The PSA 1.1 is not a complicated preamp and I think the Midi Mouse and Midi Moose were both designed to match the PSA 1.1’s capabilities and nothing more. I’m just speculating though. Tech 21 is a great company by the way!
