I run logic studio 9.0.2 on my g5 power pc, and my macbook. both operate with older OS... leapord i believe. i have really been enjoying the dubstep esentials tutorial, because it is a departure from my usual recording. normally i record from mics and use limited software insts. When i set up drag and drop kits in ultrabeat, and begin sequencing i have been experiencing crashes. this is new , logic never crashed for me. i find that i am crashing logic on both my intell processor (macbook) and my desktop(g5 power pc) with the same amount of frequency. It happens enough that i dont want to use the ultra bet sequencer and drag and drop kits(though they are really cool) but certainly logic isnt crashing everytime i use this function.
