Ableton Forum

Hello,
I'm getting high CPU loads while using default Ableton's Instruments Rack, like pads or pianos. I can't avoid that not by even setting the babyface's buffer at 2048 samples, its highest.
Whereas, a Korg Polysix or a Mono/Poly vst, loaded with polyphonic sounds and 2 internal effects, barely reaches 20% CPU usage. In both cases (Instruments Rack and Korg vsts) i'm pushing 10 keys at the same time (so lot of sounds, i guess).
Are those Ableton's instruments very resources demanding, or what else could the issue be?

Thank you.

Depends on the Ableton device. For example Wavetable can be demanding dependant on the preset.

I can't see what's the device running, 'cause i can't deploy those racks and see what's in it. I've been wondering about this: how can these sounds play, if i don't have the devices? I guess they're still there, though hidden in the Standard license?

Correct, you can still use the racks but not edit the devices if they came with Suite but you only have Standard.
