Hi all,
can anyone compare MD's sequencer with sequencer in RM1x? I really 
like stuff like midi delay, beat stretch, clock shift, event editor.. 
does MD have such things? I have RM1x but I'm going to buy 
machinedrum. Do you think I can have MD for my main sequencer and 
sell RM1x?

btw. anyone knows how many MDs did they sell till now?

Thanks,
manaay
