Found it - thanks. Forgot that single PNGs had multiple states on them, so kept ignoring the tcp background image (whoops).
Created a new meter as I prefer gradients for the master meter:
Same for channels:
Here's the updated tcp:
- Created new IO button (couldn't help myself)
- Removed bright line along bottom
- Track ID highlight more subtle
- Used ARTMods volume dial
Also changed the font to Fira Sans.
Cheers!
