Hi there Lars thanks for the reply.the issue also happens with LayR…made a test in Cubasis and Stagelight with te same presets and midi file.in Cubasis with the medium/max buffer size, trying to add notes to the midi roll or move faders makes Cubasis stutter with 2 tracks.i did the same in Stagelight and it runs smooth with 512 buffer size.so I tried using 128 buffer size and to my surprise no issues at all, the two tracks run smoothly even when editing midi and messing with the mixer channel.
Am I missing something in Cubasis settings?
Here is the video to the test
