In my experience with the mc-303, it has trouble keeping in sync with the rest of the midi instruments if it is not the master clock. I played in the clubs live for about five years on this sequencer. I paired it with some electribes, AN-200, and samplers. This was before mc-909. In all, I was able to do many remixes with it. It was a breeze to program with a midi GUI also. I used FL studio to dump midi into it to keep the time accurate. It is very hands on, and much easier to play live than the mc-505 or the mc-909. I really enjoy the old school sounds and playing this old piece of hardware. Overall it is a great piece to own if you want to play around with some outdated cheap sounds. Otherwise, I would not recomend it unless you are using it as a master sequencer, in which case you would be very limited.

can you create the same sound with the mc 303 as you can with the TB 303? for example...

Play a simple pattern use by MC 303

Basically, this is a beginner's groove-box that will do if you get a good bargain and have no other options...But you should do youself a favor and look for a used Korg Electribe and ignore the 303 altogether. It is chalk full of AWFUL preset patterns that you can't delete and has limited storage space. There's an apparent 50 user patterns available but mine would fill up WAY before that point. Unless I'm wrong, if you run it in sound module mode; say with Ableton for example you are at the mercy of the one midi channel besides the drums. This meant that all my patches were the same one...Very frustrating indeed. Hopefully that was just my error. The only things the 303 has going for it are the drums, arps, and some of the real-time controls. Other than I don't recommend this one.
