Running Cubase 7.5 on Windows 8.1 on a desktop machine (lots of memory and a fast 4 core processor). Apart from anything MS has installed, Cubase is the only application on the machine.
MOTIF XS connected to PC via Firewire and onwards linked to a Yamaha N12. Have the latest Yamaha FW driver and the Cubase Extensions for MOTIF and N12.
The green “Average VST Performance” indicator barely shows 5% usage, however the blue “Real-time VST Performance” indicator frequently jumps suddenly to 100% and lights the red overload indicator. Just before this occurs there is an audio dropout. This usually lasts a second or less but can sometimes be as much as three or four seconds of silence.
It seems to happen when there is either a lot of MIDI data being sent to the MOTIF XS or when the resulting audio from the MOTIF exceeds the nominal 0dB on the mixer meter.
I’ve tried removing VSTs from the return audio from the MOTIF (eg compressor) and this reduces the number of times the blue real-time peaking occurs but it doesn’t prevent it.
By trial and error, I can reduce this peaking still further, but never get rid of it completely, by disabling “ASIO Guard” in the device setup and by increasing the sample size to greater than 2048 (which is unusable when you’re trying to record a MIDI performance").
Does anyone else have similar experience or am I missing something here. None of this occurred using C7 on Win 7 on a slower machine.
