Am I missing something? – Model 15 Modular Synthesizer Review

I love this app, but I wondered if there’s a way to turn multiple knobs at the same time? Sound manipulation is so much more fun with as much control as possible. Maybe there’s a way to add a setting that turns off the zoom effect when using more than one finger to make this possible? Other than that this app is better than the real thing for the price, by far!!
