More clarification. Currently mixing in a completely different session. Have 2 UltraReverbs, 1 H3000 Factory, 2 Blackholes & 1 UltraChannel running. Session is 24bit 48khz. CPU is spiking to 100% red while playback is stationary, from around 30-40% average CPU.
If I inactive the 2 UltraReverb plugins the CPU spiking stops. When I reactive the CPU spiking returns (playback still stationary.)
So confirming that it is related to UltraReverb. Perhaps its an interaction with another plugin. Please advise if you’d like me to try anything? Is it worth me sending you the session?
