Tone.Meter doesn't output stereo value correctly #882

Closed thcrack closed 2 years ago

Reproduce:

Go to Mixer example
Solo Guitar 0
Pan Guitar 0 all the way to left
Play
Observe that the right channel of the meter still pumps up, albeit lower than the left one.

Probably some changes underneath messed with the meter calculation?

This is a bug. When using a smoothed meter with multiple channels, cross-channel smoothing occurs because the state used for smoothing is incorrectly shared across all channels. Opened #1018 for this.
