The meaning behind the M is simple -- it's designed by Musicians for Musicians. The MixPre-10M combines the ease of dedicated hardware recording with the essence of computer-based music production software into a lightweight, portable multitrack recorder and USB audio interface. Ideal for song creation or live performances, you can now focus on your art rather than your gear! Compared to 10T, this version does not feature TC (incl. the HDMI TC Input), 192 kHz sampling rate (max. 96) or metadata editing. In addition to the basic MixPre functionality, the M version features Reverb and Air effects, Metronome, bouncing, overdub and other music recording-oriented features. Other MixPre models can feature the same functionality with the optional “Musician Plug-in” upgrade.
