I have created a dual patch that uses the Tokyo Dreams and Modern Marimba, and while I am editing on the AstroLab (which is connected to Analog Lab Pro) I can save this patch to my user bank. I then click the Split button, because I want the pad in the left hand and the marimba in the right hand. So far, so good. But if I then try to save this edited patch to the user bank in Analog Lab Pro (not overwriting the original, but as a new patch), all that gets saved is the pad, and it gets transposed down one full step. My AstroLab OS is version 1.4.4. If I then save either patch to a playlist, they work just like they were saved in my user bank: the first patch saved has both sounds all the way across the keyboard, the second patch has the pad only transposed down a step.
—As a follow up to this: I found a split patch on the AstroLab, then edited the parts & saved this new patch to Analog Lab Pro to my User Bank. This split works correctly and works well , so I’ll role with this kind of editing process.
