My favorite that fits your request is SpeQ Mathmatics. For rolling dice use the command RandInt (random integer) along with the lowest and highest values. For your RGB example you would enter (RandInt( 1,255 ), RandInt( 1,255 ), RandInt( 1,255 )). Pressing F5 generates a new set of results. Source: almost 2 years ago

I know companies like SquadCast (https://squadcast.fm/) fix this problem for Podcasters: remote joint recording sessions with high-quality audio. Source: about 1 year ago

Squadcast is also a new tool for remote podcasting and online recording. The tool is browser-based and is super easy to use: you start a recording right in your browser by registering and creating an account. If you need to invite guests to the meeting, you simply need to share an invitation link. Source: over 1 year ago

We use Squadcast. It’s been super easy for our guests to use. It does cost a monthly fee, though. Source: about 2 years ago

I don't record and switch live. All the editing is done in post. I record via SquadCast, which records all participants locally on their devices, then uploads it to a cloud I can download it from when done. Source: over 2 years ago
