TuningForkSamples

Sonic Pi's sample bank for TuningFork: 206 recordings, public domain, fetched from Sonic Pi's repository the first time each is played and kept under $XDG_CACHE_HOME/tuning_fork/samples.

{:tuning_fork, "~> 0.1"},
{:tuning_fork_samples, "~> 0.1"}

With this package started, every name in the bank plays wherever a drum name does:

s("bd_haus*4 elec_blip")                                # a Strudel pattern
part(bpm: 120, synth: Kit.voice("perc_bell", 1))        # a loop
sample :perc_bell, rate: 0.5                            # the Sonic Pi vocabulary
TuningFork.Samples.load!(:ambi_choir)                   # the recording itself

A pitched recording is played at its own speed unless the voice is told what note it is (Sample.load! takes a :root). A number after the name — bd_haus:2 — picks a file where a name holds several, and is the same recording where it holds one.

Loading

A recording is fetched on its first use and decoded from FLAC — TuningFork.Flac is pure Elixir — then kept in TuningFork.Sample.Bank. On a live stage a recording still on its way is silent for that hit and plays from the next; TuningFork.Samples.prefetch/0 fetches all 206 (34 MB) in the background beforehand, and a pattern or loop prefetches the names it is about to play. TuningFork.Samples.source/1 points the package at another directory of <name>.flac files, local or on the web, for a machine without access to GitHub.
