Hope they don't abandon it, since it's one of the only classic "2-track" sample editors of its kind still available for Mac. If it's gone, what else do Mac users have? Adobe Audition? That's the only serious pro one I can think of.
This is what they replied (4/23/2020) to my support request regarding Sound Forge Pro Mac and Catalina.
"Greetings from Sound Forge Support, Thank you for contacting us. Unfortunately, at this time there is no clear answer to what the future of Sound Forge Pro Mac will be. There are no plans in the foreseeable future to update the program to be compatible with Catalina, and it is hard to say whether or not the Mac line will continue at all. I apologize for the inconvenience of this and we thank you for your time and understanding."
I have been using SF since 1995 (Sonic Foundry) on Windows. I thought Magix was going to keep going forward with the Mac version making it as good as the Windows one but I guest I was wrong.
