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.

Licence

Every recording is under Creative Commons Zero. priv/SOURCES.md is Sonic Pi's own list of where each came from on freesound.org, and of the sets donated by Uwe Zahn (Arovane) and The Black Dog. The collection itself is Sonic Pi's, by Sam Aaron and contributors, and this package would be nothing without it.
