Thx @Ozan_Colakoglu for bringing this thread to my attention! Somehow I missed it tough it should have been the first to promote PinchBar 
For everyone else: “Pinch to zoom with Apple trackpad not working” is exactly what I fixed on my MacBook last March, have since prepared for release and started sharing with Cubase’s community a couple of weeks ago.
As a senior software engineer, I decided to make it publicly available as an open source tool that, while running in the background, adds all kinds of trackpad zoom features to Cubase:
- Continuous pinch to zoom horizontally towards the mouse pointer (same as CMD+scroll)
- CMD+pinch to zoom in/out vertically (same as SHIFT+G/H with default keybindings)
- ALT+pinch to zoom in/out waveform only (same as ALT+G/H)
PinchBar works out of the box for all versions of Cubase, on all Intel/Apple Silicon Macs, with internal trackpad and/or Magic Trackpad, no configuration needed (i.e. for default keybindings in Cubase. It can be configured for other keybindings and even other apps like Mail, Safari, Terminal, Xcode, etc.).
At this point, I can say it’s absolutely stable and all the feedback has been very positive so far. So, please, give it a try and don’t hesitate to ask for further features or support:
I’m currently working on conventional and Magic Mouse support for all zoom features, so that Cubase (using PinchBar) will soon surpass others DAWs’ navigation features. Stay tuned
