This is a little off topic, but I noticed that Zoom released an MRT-3B drum machine.. I've looked at it and I can't really get the "B" part of the name.. What's new about the machine? From the specs the only thing I wasn't sure of is if the new B version has (1) more poly than the original. The rest seems to be the same. It also looks like they discontinued the R-Track 123, and several sites I saw are refering buyers to the MRT-3B if they're looking for something like the R-Track 123. At first look from the addition of B to the name and the discontinuation of the 123 I assumed the B meant they added bass sounds to the MRT, but I guess that's not the case.. Anyone have any input on the new model?
