Thank you nzdutchie.
However, that was a weird program seemed to want me to buy ready-made icons. I gave up after a few minutes.
However, persevering, I discovered this in this forum
https://forum.cockos.com/showthread....ht=buttonmaker
and it works a treat - simple and effective. So now I have icons with bright blue/green background and black text, so easy to see. Works well even if I darken the whole theme. I could even have borders to the icons if I wanted and size does not seem to matter - I have 30x30, 60x30, 80x30 and 90x30, can choose font and font size to match... excellent!!
One thing, the download is called Buttonmaker6_WIN, but inside the zip it is called Buttonmaker 7.
It was a shame the video is no longer available but there, half the fun is trying it out.
I wonder if someone could answer:
This little prog allows me to "save button as..." which saves a .csv file - looks like an excel file, and also allows me to "save PNG horiz" and "save PNG vert".
For safety I saved both the .csv file and the PNG horiz and put them in the toolbar icon folder in Reaper where the icon is then usable via the customise option.
Do I need both of these to make it show up?
