I’m new to the QC and I’m at my wit’s end—I could really use some advice.
I’m currently building a preset on the QC Mini, but I keep getting an error message: “Not enough CPU capacity, remove some blocks from The Grid first.”
The blocks I’ve lined up are just: Wah, Compressor, OD, Amp (Brit UBL Lead), Amp (Brit UBL Lead Clip), Noise Reduction, Cab, Chorus, Chorus, Rotary, Analog Delay, and Plate Reverb.
They’re just arranged in a straight line—no IRs or Captures are being used.
For the record, the editor shows CPU usage at 43%…
When I look at presets uploaded to the cloud by others, they often have much more complex setups with tons of blocks, so why am I getting this error?
I want to set up four scenes: Scene 1 (Crunch), Scene 2 (Crunch 2), Scene 3 (Clean), and Scene 4 (Lead).
I want to add an amp for the Clean sound, but I can’t select it because of that error.
Could someone please explain what’s going on? Is there any way to get around this?
Quad Cortex has 4 processing cores. 2 cores are used for the top two rows on the grid, 2 cores are used for the bottom two rows on the grid.
If you load up all of your blocks in the top two rows, you will reach closer and closer to the 50% CPU mark–in other words, maxing out the CPU allocated there.
You need to spread out your blocks across the top AND the bottom rows. At the end of Row 1 or Row 2, send the signal to Row 3. From here you should easily be able to add more blocks, and you’ll find that you can go well above 50% CPU for a whole preset.
@fucchan I’m currently running 3 amps in scene mode, 1 of which is a capture, and plenty of effects. My CPU usage peaks @ 64% with the most resource-hogging blocks engaged. Happy to share the preset as a baseline for you to drop your own stuff into if you’d like.
If this is the preset I saw a picture of on FB, and you haven’t resolved the issue yet, I think you should upload it to the Cloud and let us check it out. You have it spread across the right lanes to optimize core usage, it looks a little suspicious to me that it’s not allowing you to add devices. It may just be the the UBL amp blocks are superheavy DSP-eaters.
