I actually don’t, but they come with the Mono, Stereo, and Master mixer modules from cf.
So if you think just about a large drum setup with a synths, samplers, then add to that bass, pads, leads, textures, layering, ect, it’s fairly easy to imagine having that many VU meters included within the cf modular mixing system. 16 channels, with a few master faders is really not that big…
The other time it happened was when I made an 8 channel recording set up, with an additional stereo mix recorder, all inputs and outputs busable. I used BogAudio VU meters both pre and post mixer on all 8 channels, plus a couple that come with the 2 track Recorder. That was the 1st time I noticed things graying out and disappearing.
I really like the cf mixing system. I tested 24 channels of it against the mscHack 24 channel mixer and it was actually about the same, cpu wise. However, if one connects the solo system, it will make short work of one’s cpu, so I don’t use the solo system on it.
