Not sure if this is the right place to post a potential issue on my FM9 with FW 8 public beta 1 but here goes...
I have a "The Final Countdown" synth patch that I've been using fine for a number of earlier firmware but on this one, at a gig it maxed the CPU and cut sound so we couldn't do the song. I believe the CPU used to sit around the 83-85 percent mark but can't swear to it without reloading old firmware.
All other pre-sets are fine. and I usually triple check them after new FW updates (A/B by recording and volume checking each scene on each preset etc.) but must have missed this one or it was just fine whilst I was checking.
This pre-set is probably due a ground up rebuild anyway as its not my favorite amp tone any more but I've 'fixed' it by removing the non synth chorus block that I wasn't actually using and by removing a few unnecessary shunt.
Anyway, I thought i'd upload it here and report it for others just in case its an issue worth investigating.
