I have a Simmons Stryke6 USB drum pad connected via Camera Connection to my iPad Pro. In GarageBand and in the Stryke app, I can play reasonable rolls and fast patterns. In just Cubasis, lots of pad hits are missed and it’s basically unplayable. Only simple quarter note patterns are reliably detected.
Thanks for the suggestions. I followed all four steps, but the problem still persists. (I was actually already on Ultra Low from my own attempts to fix the issue.)
I made a quick video showing a comparison between Cubasis and Garageband responsiveness:
Garageband, Auria, and the Stryke app all behave similarly, playing sound for basically every hit. Cubasis is the outlier, not triggering a sound for perhaps 40% of the hits.
This is on a freshly rebooted, up-to-date, iPad Pro 12.9", so processor speed shouldn’t be an issue.
If possible, please upload the Cubasis project to Dropbox and let me have the download link via private message.
That way we can have a look and evaluate what’s happening.
