I have installed nano 2 on my shiny new iPhone 11 pro but I am getting bad latency. I’ve changed the audio buffer to very low but this seems to make no significant difference. If for example I create a drum part using the 808. When I hit the bass drum it sounds after my finger has taped the pad by I am guessing very roughly about 1/3 second. I used to use NanoStudio a lot on my iPhone 5 and did not have this problem then.
