WINNING!
TLDR; The combo of a eBay keypad and the USB Overdrive utility (for Mac) is a winner with Resolve, and likely other NLEs too.
Longer version....
My portable editing setup now includes the BM Speed Editor, the Beatstep controller and Beatstep Resolve Edition software, and now this little custom keypad.
The keypad and USBOverdrive allows macros, so you hit one key and it sends the computer a string of keyboard commands. In combination with the keyboard shortcuts in your NLE, you can make it do pretty cool stuff.
In the Cut page, the Speed Editor works in a certain way which creates limitations, and Resolve has a few bugs (in my version at least) that also limit things.
I have set keys that highlight the current clip, trim start/end to playhead, then unselect all clips. Or similar but splitting the clip. Or similar but ripple deleting the clip. These are mostly workarounds to the peculiarities of Resolve and the Cut page and Speed Editor, but I think it's an excellent addition to using it.
I can navigate using the wheel on the Speed Editor, hit a key and trigger a macro, and then fine-tune on the Speed Editor if further refinement is required, and then keep going. I had some, let's say, distracting, workarounds that I had to do in order to perform these functions involving not only having to take my hands off the controller, but also triggering my frustration with BM at not building things in more flexible ways, which really took me out of the zone!
