MIDI Guitar 2 iOS latency - any hope to fix it?

Hi! I haven’t used this app for quite a long time, but now I need to track MiRack built synths in my new project. I use a simple iRig as I don’t want to grab rather a weighty audiointerface and a bunch of cables around. I noticed a very huge latency (1024) on my iPad Air 2 which I cannot change. In the prevoius app version there were no such terrible latency problems. Such latency makes MIDI Guitar 2 totally useless. Is there any way to fix this problem in the future?

The buffer inside iOS MG is fixed to 256. I’m not sure how you use MG and what version you are using. The latency may also be governed by the other apps you are using, having their own buffersettings.
