Hello,
there is an issue with Studio One and Spark. I'm running Version 2.0.4 and from time to time Spark causes Studio One(S1) to Drop, because it uses 100 % or more of the CPU..doesn't matter if it's playing..just loading Spark is enough. Would be nice to get that fixed.
I'm running on Mac Lion 10.7.3 , 4GB Macbook 2,26 Ghz Core 2 Duo, internal Audio
