I know you can use the slider in the upper right corner in the arrangement view, but when I look in the manual, it seems like this is the only way to increase waveform height?
Is it really true there is no way of assigning a shortcut or mouse wheel to this function?
I too have looked many times for this. I use this all the time in Pro Tools cmd+option+[ and ] zoom waveform and cmd+shift[ and ] zoom MIDI events and then on the Icon you can do the same with the wheel and it is very smooth (no MIDI zoom though). What I love is you can actually also go smaller and cmd+option+ctrl+[ returns you to your default value. Cubendo only goes larger which for the most part is more often what I need.
This Sound on Sound article lead me to think there was a shortcut.
“I’ve set these as Option-G and Option-H on my Mac, so that the ‘G’ and ‘H’ keys control both horizontal zoom (without the Option key) and vertical zoom (with the Option key). Of course, you could similarly use shortcuts to increase or reduce the height of the waveform within an event.”
On a Mac using Cubase 8.5 Pro -
Horizontal zoom = Hold command and use mouse scroll wheel
Vertical zoom = Hold command+option and use mouse scroll wheel
