This is my shameless rip of the wonderful Ableton Live.
Download it here.
Note - The mute function in Live acts as a track on, track off button. I've made it that way here also. If you don't like it, take a look in the theme folder where you will see a folder with Reaper style mute and solo buttons. Copy to the theme folder to change the look.
Also look in the theme folder for the splash screen.
Enjoy.
