I have the knobs on my Alesis MIDI controller mapped to channel faders (via a CCK), and have a constant issue with lag and “stiction” when trying to control faders. The faders will respond to the input in a rough manner and suddenly ‘jump’ to where they should have been. For example, I will turn knob from 63 to 67, but Cubasis jumps from 49 to 67 instantly, without the increments in between. If I set the knob to 0 (min) or 127 (max) too quickly, the fader will stop short and then finally jump to the proper position after a second or two. This is not just a visual bug, the sound level will also jump around dramatically, which is quite unsatisfactory.
If I map my MIDI controller to the pan control on the same fader channel or another knob elsewhere in Cubasis, it behaves just as expected (totally accurate real-time polling of MIDI input). The issue only seems to affect the faders, and it seems more of a lag issue than any apparent MIDI latency.
If I record my fader changers, on playback it’s mostly smooth again! Although it still isn’t 100% as input.
I’ve restarted, reset, reinstalled. The issue is consistent and persists on a fresh single-track project with no instruments, plug-ins or audio loaded.
Thanks for any suggestions.
