[FR] multichannel jackmeter

Hi,

It would be great if cadence-jackmeter could respond to number audio channels. It seems two ins and outs are hardcoded.
thank you

I would like to see such a feature implemented as well. I think of something more general, like this example:

cadence-jackmeter \
  --client-name meters \
  --color-scheme cyan \
  --add-connect system:capture_1 \
  --add-connect system:capture_2 \
  --color-scheme green \
  --add-connect system:monitor_1 \
  --add-connect system:monitor_2

Proposed semantics, in that order:

• The JACK client for this cadence-jackmeter instance shall be named meters.
• Every meter added after --color-scheme cyan shall use the "cyan" color scheme. (Think of that color theme as the one used when, currently, you pass -in.)
• Add a new meter for JACK port system:capture_1.
• Add a new meter for JACK port system:capture_2.
• Every meter added after --color-scheme green shall use the "green" color scheme. (Think of that color theme as the one used when, currently, you pass no args.)
• Add a new meter for JACK port system:monitor_1.
• Add a new meter for JACK port system:monitor_2.

This should give me one JACK client called meters with four input ports, each one connecting to the respective client's port, affecting four meters, displayed from left to right in the order added, using different color schemes as described.

What you currently get when simply calling cadence-jackmeter (but generalized to all playback ports instead of just two) might then look like this:

cadence-jackmeter \
  --client-name M \
  --color-scheme green \
  --watch '*:*' 'system:playback_*'

And what you currently get when calling cadence-jackmeter -in (but generalized to all capture ports instead of just two) might then look like this:

cadence-jackmeter \
  --client-name Mi \
  --color-scheme cyan \
  --watch '*:*' 'system:capture_*'

The idea expressed in both cases is similar: Watch all clients ('*:*) for connecting to or disconnecting from system:playback_* and system:capture_*, respectively, and connect and disconnect the meters accordingly.
