Re: ppqn resolution query

2005-11-21 by analog1k

Thanks for info...

I always thought 96ppqn was a much tighter timing, it
seems things get sloppy [correct me if I'm wrong] at
higher resolutions?  Besides I never work above 90bpm,
more like between 50 and 80bpm [depending on what you're
actually using the P3 for].

Thanks guys for the input.  ;)

Cheers,
A1k
