In one of my rackspaces I need to use 5 intances of Korg Triton extreme.
For the first time of my (short) use of GP, when playing using this specific rackspace I noticed a few cracks/noises randomly and I didn’t know why. Then, I noticed that the CPU usage was between 48 and 56%, much higher than my other rackspaces (typically below 30%).
So, do the noises occur due to the CPU usage?
Is the kork Triton Extreme vst a CPU “eater”? Any way to solve this?
What is the safest level (maximum CPU percentage of use) I should set to avoid this noises?
To me it does not strike me as “abnormal”. There are some plugs ins (or particular sounds) that can eat up a lot of CPU.
But, there are often adjustments than can be made that do not compromise the sound, especially for live performance.
For example, there may be “quality” settings that affect CPU, which can be adjust. To the extent you might want the highest “quality” setting for recording, you probably do not need that for live performance. The “lowest” quality setting might work fine. You need to evaluate CPU use with and without different quality settings.
A lot of times effects are burning up CPU. Do you need them all? You need to evaluate CPU use with and without different effects.
Number of voices (polyphony). This can effect CPU. Frankly, in a live setting too much polyphony can cause more harm than good. Maybe look into adjusting that.
Thank you for your feedback.
I mostly use combinations from Triton. I create my own combinations, layering the keyboard and then import them to GP. So, some rackspaces are just one instance of Triton Extreme.
About RAM: Unfortunately my MAC only has 16GB RAM and its a Mackbook model that doesnt allow upgrade, so I will have to stick with it.
Should I lower the sample rate to 480 or 448 samples? Wont it make difference in terms of global quality sound?
Totally with you on this one … I started off using some awesome strings and ended up with Yamaha Motif XF strings section which uses about 75% less CPU and sounds just as good in a live situation… No need at all to use massive libraries for live gigs …
Here in Spain we play much varied styles of music, from 80’s pop/rock to latin style… Some latin songs I start off with an awesome ballad piano with all the bells and whistles (big fat sound with lovely reverb and pad, etc 40-50% CPU) but then I change it to a simpler piano ONCE the song changes in to merengue style with Piano tumbao technique… I don’t NEED the massive piano sound to play tumbaos … Look for what works GOOD ENOUGH in each moment.
