i had to open up my zoom mrt 3 for maintenance, and i tought "why not check its possibilitys.." so far i found that it could glitch sweet, it comes very close to the casio sa style loops, all very strange drum/tonal loops once glitching, you can change to another -totaly differend- glitchloop , using the + and - buttons. it also seems that it's sequencer can be operated normally half of the time.. i didn't try yet, but i guess it would listen to midi clock as well there is also some space for switches etc.
so i think it will be a nice little project, specialy if the glitchloops do listen to midi clock.. at the moment i am still doing the research , but if i start soldering, i will take some pics for you.. i think it is a nice little drum machine anyway greetz, zzpecht
