I suppose this could be done using succesive loops of different (but metrically related lengths) Has any one tried this? Would the version EDP version 5.0 loop copy help?< I guess your question is referring to MIDI sync problems, isn't it? I'm a Jamman user, so the MIDI features I deal with are much more limited than the EDP, but I have made "additive rhythm" loops without MIDI sync for practicing Balkan/ Armenian grooves (7/8, 9/8, 10/8 11/8, 15/8 etc). But in these cases, nothing remarkable was involved, it was simply a matter of making a loop alone. Return questions: (1) What sorts of MIDI sync features are possible on the EDP when one wants to sync, for example, a 7/8 groove (3-2-2) created using the Multiply feature to a drum machine or another looper? I ask this because a friend of mine will be travelling to Austin for the SXSW and he's goning to buy an EDP there (I live in Germany and they aren't available here). (2) Which leads me to my second question: does the EDP have a power supply switch for European voltage/ frequency or is an additional trafo necessary?
