While using Stratus you can chain multiple effects together at once. Each effect uses a different amount of processing power, so the total amount varies. Once you reach Stratus' dynamic CPU limit a dialogue box will display on the app letting you know.
On average, Stratus can typically run at least 5 effects at once, however the total number may range from 2-10, depending on which effects you're using.
You are also able to add multiple instances of a single effect to your digital pedalboard.
