Yes I think If someone give me all arranger, I take the SD-1. Ok there is bugs... buf I hope the SD-1 evolute. And I love to use it!
what I don't love in the SD-1: the sounds are very good because for exp, in the sound "strings", ther is 3 sound plays at the same time (3 MIDI chanel) but in midi files, the sounds are less good. (but it's better than other arranger!)
perhaps the not official version 2.0 is not realased => bugs.
if someone want it, send me some styles (oriental+++ if you have) and I send you the version 2!! :-)
I have it by my dealer in exclu.
