The Micro Rhythm Track!
Zoom's MRT-3 Micro RhythmTrak is an incredible stand-alone drum machine, and is also the perfect add on to any digital audio recorder that lacks a built in rhythm programming. The unit has a consistent appearance and functions with the new MRS-4 4 track digital recorder. The MRT-3 features 7 velocity sensitive drum pads, 50 preset and 20 user drum kits (user can make an original drum kit), 200 preset and 99 user patterns, 99 song memory (maximum notes/events: 10,000), 21 note polyphony, quantizes to 96 PPQN, and tempos of 40-250 BPM.
Connections include a Mono out (Line) 1/4" phone jack, Stereo out (Line and Headphone) 1/4" stereo phone jack, a MIDI Input and a Control foot switch jack. The unit is powered by 4 "AA" batteries or an optional AC adaptor.
The MRT-3 links to the new MRS-4 4 track, sending its output to the MRS-4's AUX input and is synchronized through the MIDI clock, acting like a built in drum machine.
