I have been working with MIDI a lot recently and find that some notes in the mix do not play back in the right time, they are late and further when exporting a job to a project, some of the notes are missing altogether, (this does seem specific at this point to Drum tracks). at times, notes play at the wrong time, this will also get exported as such. True this could be a memory issue (I have a Mac with 8GB, using Studio One Pro 3.3 in El Capitan) but I want to vet this. Also I have found by saving as... and the immediately adding to a project, will resolve the missing notes in the project.
As an associated question, is StudioOne multi-threaded? If not this would sure be a great enhancement for the Mac, version.
Thank you for your replies.
