Hi Atlas007. I use the novation SL64 MkII. All your suggestions? I can't find them on this thread, Maybe you could send again if relevant? However, I spent hrs yesterday with the Novation specialist. He consulted with his colleagues. Here is their recommendation since i use catalina and have trashed the Automap which isn't compatible, I will try it today and see if the distortion as well as my volume drop due to creation of CC 11 event by hard pressure on keyboard goes away. Thanks so much for your help I'll get back to you when I've tried their suggestions. Here's what they wrote last night,
Hi Jim,
Thanks for getting in touch via live chat earlier.
To confirm, as the aftertouch (expression) data isn't appearing in MIDI Monitor, this will isolate the issue to the Control Surface setup or possibly an assignment acting up.
As you are not using Automap, please could you remove your SL MK2 device from the Control Surface setup in Logic?
Should you wish to remap the SL controllers in Logic, you can manually assign these as per our guide: Manually assigning controls in Logic Pro X without using Automap/Logic Scripts
Then, to ensure the aftertouch message hasn't been accidentally remapped in Logic, please try setting the Controller Assignments to default:
Use controller assignments Easy view in Logic Pro

Use controller assignments Expert view in Logic Pro

I hope this helps. Please feel free to let me know how you get on with the above.
