[PD] VU / Peak Meter ? - external or abstraction

Sweet. I'm going to try out Peter Ps abstraction.

Additionally, I know this is not what you are asking for, but there is iemlib [fadtodb] and [dbtofad] which matches the default "MIDI" range of a slider to that of a VU in dB or conversely. I use these to match a control vslider to the same height as a vu for my faders.

When I transitioned most of my patches to vanilla-only, I made abstraction versions of these using lookup tables, [m_fadtodb] & [m_dbtofad] in the rc-patches: https://github.com/danomatika/rc-patches <https://github.com/danomatika/rc-patches>

There are also some simple channel faders: [g_chan] & [g_chan2]
