I’m using 2 possible midi sources, namely a keyboard and also edrums. The keyboard is fine but the drums are causing doubles. The midi log is showing only note on and note off so I’m finding this a bit strange.
ctrl A and ‘delete doubles’ is not doing anything.
In your first post you say that there are doubles, but the “midi log” is showing only note on and note off - what is this midi log? Are you talking about the list editor? Any chance of a screenshot?
Second, you assume they are being recorded, but I don’t think assumption is the way forward! How is this behaviour manifesting itself? Are you hearing the doubles? On what tracks? On what instruments? When you are playing them in, when you are playing back, or both times?
I’m not sure why you’re saying there are doubles at the moment, or when it’s happening, so it’s difficult to offer any suggestions.
What is the MIDI device you are using? Does it have “zones” or “groups” enabled.
One of my MIDI keyboards has a “zones” or “group” feature which allows you to send MIDI out different zones on the keyboard and you can assign those to different MIDI channels, and Cubase will record them all.
Sometimes I accidentally hit one of the group buttons and get doubles.
Cubase does not filter midi in , so it will record any channel being sent to it unless you set up an input filter.
Kontakt is able to play only the channel you have selected as the input channel for a particular instrument.
Check out the device menu, MIDI tab. Here, on Windows, I have Fireface Midi Port 1 (in/out) and some generic Windows MIDI items. The latter have to be unticked, otherwise I’ll get doubles as well.
‘Remove doubles’ from the MIDI menu basically works, but as MIDI timing isn’t that accurate by nature, the function will only delete real doubles - notes that are in exact same position. They usually aren’t when coming from two different sources.
