funny to see talk of the yamaha qy10 - i just was re- acquanting with mine it's great!! if you see one used- grab it!! these are great little units that do WAY more than you may think...it's worth it just for the fact that a device the size of a videotape (i store mine in a video sleeve) - is not only an 8track sequencer, 36 sound synth module, drum machine, but can quickly be set up as a "looping" jam partner - any groove in any key over any chord, etc.. i've written music on the beach in jamaica with this - with 'phones it's amazing what you've got. The unit TOTALLY died when Yamaha brought itout - for one reason- the ridiculously small, one line screen!! Yikes...!! while i'm used to it - i'm sure the QY10 is easier to use with it's big screen.... so - all in all - my recommendations are that this piece rules for loopers because: -can be found cheap -small, great for stealth loop gigs -nice for adding drum bites or a splash of synth tone to a loop -easy 'step time'programming lets you plug in tough passages, from printed music, for analysis.... -if you only ever use it for warming up over a metronome and a fun scale - it'll pay for itself. have fun andre'
