Changelog

0.1.4

Stage.pattern_gain/2 and Pattern.Player.gain/2 scale a pattern's whole output, sounding notes included; 0.0 is silence.
The README opens the tour notebook in Livebook from a badge, and names the projects this library owes to.

A TuningFork.Part synth may be a function of the note — an instrument — and TuningFork.Kit.instrument/4 makes one from any sound name, so a part plays a soundfont or a bank recording at each note.
Part.repeat/3 takes a string of x and . as well as a count: a pass plays on x and keeps its place silently on ..
A bank the kit does not have starts TuningFork.Strudel.defaults/1 loading, and a voice asked for with wait: true waits for it; Strudel.defaults(wait: true) and Sample.Set.load_all/2 are the waited-for forms.
sd is a snare name; mini-notation reads -.3.
Envelope.spanning/2 drops the envelope's hold, so a note asked to last seconds does — a voice with a hold, such as a soundfont's, used to ring on past it.

bank/2 keeps the bank name on each event; the kit plays the recording registered as bank_sound when the bank has it, and its own drum until then. Before, a name in TuningFork.Kit.banks/0 never reached the recordings.
struct/2 keeps every note sounding at a structural step, so a voiced chord under struct sounds whole.
use_synth takes a sound name — use_synth "gm_epiano1" — played at each note through the kit. TuningFork.Kit.known?/1 says which names qualify.
A sample file whose name has a space in it is fetched.
A step whose edge fell a rounding error inside a query span could be reported twice; Pattern.query/2 leaves such slivers out.

First release.
