thanks a lot Carl heinz for your feedback !
I will try different midi set up with the LM1 (the one I would get as no sync input anyway as this revision was trying to reduce cost on the connections side).
I will discuss soon with Bruce regarding the lm2 service I will request,
all the best,
P.S : if you are interested I scanned an old review (82 !) of the lm2 which has a lot of comparaison points with the lm1. Sorrry it's a big file,
