When using MIDI-Thru on a MIDI channel to play external MIDI instrument from external MIDI controller, a noticeable latency builds up after a few minutes. Closing Cubasis 3 and re-opening resolves the problem temporarily, but after a while the latency returns and a new shut-down and re-start is required. Very annoying.
Expected results: No latency on MIDI whatsoever at any time
Actual results: Noticeable MIDI latency builds up after a few minutes, making playing impossible. From investigations using headphones in various parts of my setup, it’s not an audio latency, it’s definitely a MIDI latency. The is issue temporarily resolved by shut-down and re-start the app, but only for a few minutes, after which the latency returns.
Hardware: iPad Air 3rd Gen (2019)
Audio/MIDI Interface: iConnectivity ConnectAUDIO 2/4 and Apple CCK
Software: iPadOS 14.3, Cubasis 3 V3.2, iConnectivity Firmware latest (V2.0.1)
I have set-up a template with 3 MIDI tracks each set to output to a different channel for each of my external gear, and I mute the ones I don’t want to hear. A single audio channel is used to hear the audio and apply effects/record as a start point for a project. The latency is apparent not only on the audio channel but also when I use headphones on the external gear being triggered by MIDI. Shutting down Cubasis 3 preserves the template exactly as it was when it re-starts, and for a few minutes at least the latency is gone, but it then builds up again. I searched before posting, the only thing I could find was to do with Cubasis 2 and an older iPadOS so not relevant.
