No, I don't use Logic and Ableton together. I connect all my midi devices using USB. I don't use a separate midi interface. I do use a USB hub and have had not problems previously. To test, I did disconnect everything and connected the Kronos directly to the Mac without going through the hub. I have not tried enabling Bypassing All Control Surfaces. I'll give that a try.

I'm trying to create a midi track within Logic which controls the Korg Kronos. Logic is receiving midi from the Korg (i.e., I can play virtual instruments and other connected midi instruments like my Nord Stage 2), but I can't establish a midi track that outputs to the Korg. When I go to create a new track and select "external instrument," there is a drop down that lists my other midi instruments, but does not show the Korg even though the mac OS recognizes it. Interestingly, it works fine in Ableton Live, just not in Logic.

Logic Pro X isn't recognizing my Korg Kronos 2 as an external instrument any longer. It worked previously, but I haven't used it with Logic in a while. Tried to use it again, and now it is not recognized. It will receive midi input from the keyboard, but does not recognize it for output. The Kronos shows up in the Audio/Midi Setup on my older macbook pro. I use several other external midi devices, all of which are working fine. I've updated the Korg Kronos usb midi driver, updated to the most recent version of Logic Pro X, and still not working. Wondering if it is just a simple setup issue that I'm overlooking.

I've been using MainStage on my MacbookPro for several years and the only real performance issues I've had all seem to involve Playback. Recently, I created a backing track in Logic. I've bounced it down and it plays fine by itself in iTunes and in Logic. The file is about 73 measures long. When I use it with Playback, the audio sounds great until it gets to about measure 63 and then it abruptly goes silent. Playback continues to run, and you can see the graphic of the audio file continue to scroll, but there is no sound. The silence occurs at the same place every time. I've tried bouncing the track as CAF, AIFF, and MP3 with the same result. I have other tracks that work fine, all created in Logic. I recently upgraded my OS to Yosemite, but I was having this problem before upgrading. I use a Focusrite Saffire Pro40 as my audio interface. Anyone else had this problem or have any idea what is going on? JayPeeCee
