Hello fellow Mainstage and Logic users, I'm running the following system: 21.5" iMac 2.5GHz, 8GB RAM, OSX 10.6.8 Mainstage v2.1.3 running in 64-bit mode Synthogy Ivory 2.0.5 (playing from Yamaha sample set) RME Babyface Yamaha S90ES I'm experiencing random stuck notes on two identical rigs. CPU level is well below 10% and memory used is well below 30%. Not been able to recreate the issue on my personal rig in my studio, which uses an M-Audio controller. Next step is to use a midi monitor app to monitor the data coming from the S90 as I suspect that might be the cause. These keyboards were recently refurbished by a reliable shop here in town as they were acquired from another production that closed several years ago, but you never know... Any thoughts would be most appreciated!
