Filter

Adds menu entries to each EQ/filter and tracks for transposing by semitones.

Supplies a “live-transpose" slider to transpose either only one eq/filter device, all eqs/filters in a track, in the signal flow or in the whole song.

Picture the signal flow roughly as a tree structure, starting with the master or a send track as the root node (with possible parallel routing, too) until the leaf nodes, which can be either the playing tracks or even the instrument dsp lanes.

Observes track names and automatically assigns colors to tracks by predefined filter rules.
It's comparable to Reapers SWS auto color extension. How it works is best explained by example:

E.g. filter is: kick, snare, hihat, drums -> color red
E.g. filter is: synth[0-9], lead -> color green
