I've got one of these,
I don't use it that much ever since I got Reason aka: God's gift to non-drummers !
anyway, It's really useful for drum n' bass. It's basically a Roland 303 bassline and a 909 (I believe) in one unit....sorta like the software program "Rebirth" .
what kind of sound are you going for??
I'll tell you this: we all learn differently and I do it 'hands on'. I cannot understand manuals or tutorials for the life of me, the best way for me learn it was just to screw around with the buttons. It may seem confusing at first but take a chance to play around with the RM1X for a bit,,, that'll make
the MC303 seem like a toddler's toy! lol.
overall the 303 tends to be in a "medium" learning curve. Right in between the Electribes (super easy) and the RM1X (super hard...for me at least)
I have an industrial/drill project that I contribute to every once in a while....even though he has reason, the songwriter ALWAYS uses his MC303. I guess he got so used to the platform that it became 2nd nature. Just some words of encouragement.
But I may be able to give you a few tips/ideas if you clarify what you're trying to do.
oh,,,,,forget the presets. You don't really want to sound like
that do you? ....just messing with ya.
