Yeah I have a 3 channel amp I just cloned and to use 3 proxy clones it eats up significant cpu. Very similar to an agoura amp.
had to cut some blocks out of my preset.
top row: simple pitch (can’t use poly), compressor, phaser, 2 proxy clones
bottom row: one proxy clone, volume block, gray flanger, stereo elephant man, two stereo reverb blocks and the deluxe looper.
so it’s not the worst. There is room for a few things but you definitely have to be intentional.
