ANA demo is overloading CPU

Hello, I have been using the ANA demo for some time now. I am running FL Studio. I love the synth, however, if I load up a few instances of ANA, FL’s CPU get’s overloaded and this leads to a whole host of problems.

Does this have something to do with it being the demo version? Or is ANA just a synth that uses up alot of CPU? I am wondering because I am trying to decide whether or not to buy it.

ANA can use quite a bit of CPU on particular presets.

Try turning off reverb, and adjusting the polyphony at the bottom left. 4 voices should be enough for most things.
