overloads my cpu

i love this effect. it’s probably the best ios compressor availible. but it’s so difficult to use because no matter the size of the project i put it on, it always overloads my ipad to the point that it basically becomes unusable and i have no clue why. my ipad can comfortably run multiple instances of SFZfizz, decentsampler, IM1 and more in the same track. there’s no reason for a compressor to be more demanding than advanced synth engines and samplers. please make it lighter.

Response from developer

Have you tried turning off the animations and/or glow? We added those so that people with older iPads could use it. Look on the Settings panel.

Incredible

FAQ

What is Evil Otto?

Evil Otto is a multiband OTT compressor that applies simultaneous upward and downward compression across three frequency bands. It's designed to create dense, hyper-detailed audio.

How does Evil Otto's three-band compression work?

What kind of control does Evil Otto offer?

Evil Otto provides precise control with fifteen parameters, including Depth, Time, independent Down and Up amounts, per-band thresholds, per-band output levels, and input/output gain.

Can Evil Otto be used for rhythmic effects?

Yes, Evil Otto features a sidechain input that allows you to duck the compressed output with an external signal, creating rhythmic pumping effects. A dedicated Listen mode helps verify routing.

Does Evil Otto have ads?

No, Evil Otto does not contain advertisements.

Evil Otto is available for a one-time purchase of $4.99.

What devices is Evil Otto compatible with?
