PercX crashes when dragging midi notes into Logic pro X
PercX crashes when dragging midi notes into Logic pro X. I am on macOS Catalina. Please advise.
Here is the error message details:

+1 for this post--- @waeld I am having the same symptoms today in ProTools as well. I am unable to upload my crash details since it is in Console and I cannot get it to paste into Pages for some reason. Auddict folks: any thoughts? I'm out of business with Perc X until I can get past this one. Ty!!

I'll take a look, but I tested the dragging feature (at least in Logic). @lctofu are you also using Catalina?
Hi Chris- Thanks for the reply!
No- I am a holdout, using High Sierra still, 10.13.6. The OS updates have been brutal and I am still waiting. If helpful I can email you the Console crash log. Just let me know where to send that.
@Christoph-Hart So what should I do? I just purchased the plugin and the dragging never worked, it crashes since day one. Should I uninstall and reinstall? If it won't work I'll have to ask for a refund. Thanks.
@Christoph-Hart ditto here. Dead in the water.

I‘m currently working on an update and I‘ll try to include a fix. Does the crash appear every time you drag something and does it crash if you start dragging or if you drop it in your DAW?
Thanks for your assistance- fingers crossed.
@Christoph-Hart Logic pro X internal error message appears with two options to choose from (Crash or Continue), as soon as I click on the PLAY symbol or TARGET symbol of PERC X (in Edit A window, Drag), before even being able to drag and drop the midi. Thank you.
