These are new proposed pattern generators. They'd be pretty easy to do, but it'd be good for someone wanting to get into the pattern generator.

We need to be able to pop up a color chooser (which Juce already supplies for us), get the results, and report them back to the main program.

From https://github.com/rec/echomesh/issues/154, we might add these new envelope keywords... start: time offset to start playing the envelope - may be negative. shape: linear, exponential, log, ? sustain, release: the envelope...

Small but would be a useful start for someone who wanted to get going with the transport layer.

We want a display Element that shows the current mic level for the current unit. This either must be done on the Raspberry Pi or we need to resolve https://github.com/rec/echomesh/issues/459...

Make sure all the scores still work and that they're not duplicating each other.
