- https://en.wikipedia.org/wiki/Sampling_(music) - the act of taking a portion, or sample, of one sound recording and reusing it as an instrument or a sound recording in a different song or piece
- https://en.wikipedia.org/wiki/Sample_library - a collection of digital sound recordings, known as samples, for use by composers, arrangers, performers, and producers of music. The sound files are loaded into a sampler—either hardware or software-based—which is then used to create music. Sample libraries appear in a variety of forms: As a tempo-based musical phrase that can be looped (repeated in tempo with the arrangement), or edited in a cut and paste collage fashion; Collections of note-by-note recordings of musical instruments for playback on a digital sampler, known as multi-samples. This method of sample playback is to construct a playable instrument, or emulation of another instrument, from a sampler or computer; One-shot hits or stabs of non-tempo-based audio, particularly for sound effects.

- https://github.com/tidalcycles/Dirt - Experimental sample playback. An unimpressive thingie for playing bits of samples with some level of accuracy.
- JTrigger - A drum machine/sample player for midi input. I've left out the sequencer and the plugin support because it can be done by other, better programs if it is needed. This is a true unix program - does one thing, and does it well. You can get effects support by running it through something such as Jack-Rack. Each sample conviently has it's own JACK output port to make your life easier. No matter how much time I spend, it's likely that I won't exceed the capabilities of a dedicated sequencer such as Seq24 without greatly increasing the size and resource usage of this program.

- Shortcircuit - created as a reaction against the ongoing trend where software samplers are being designed with the primary intent of library playback. It is intended for people who, like us, consider a sampler to be a musical instrument in its own right, and not just a way to emulate other instruments. It has been a very high priority to make sure that adding and editing individual samples is as fast and logical as possible.
The sample hierarchy in shortcircuit allow you to place samples directly at the highest level of the multi, without having to deal with instrument hierarchies and patches. Want to add a sample to your song? Just drag & drop the sample into shortcircuit and you're ready to go. Samples can be put in groups for multi-sampling and kit-building, but the complexity is only there when you need it.

No MIDI control.
- Loopcenter - a program I wrote basically as a music-practicing tool. I didn't want to shell out for a Boss Loop Station guitar pedal, and I figured I could achieve the same functionality pretty easily with a simple program. Loopcenter lets you simply record loops for any audio you route to it (via JACK), and it plays it back in a loop. You can overdub the loop as well. Every recording is rounded to the nearest measure. Accordingly, you can adjust the beats per measure, and the tempo.

It has also a lot more of handy features like applying fades, gain adjustement, normalize, convert to mono/stereo, etc etc... Its main goal is to prepare audio loops for live performence (with e.g. SuperBoucle, Luppp, Giada, Bitwig...). LoopTool is mainly based on SoX.
- Smasher - cross-platform audio loop slicer designed to create sliced loops from WAV, MP3, FLAC or AIFF files in seconds without a sequencer. Effects include filter sweeps, phasing, flanging, delay, and distortion.
No MIDI. Needs pd, csound to build. Also a specific build of wxgtk2 
- manic - an 8 slot random sample player where you decide the samples, but manic decides when to play them. Samples are triggered according to their probability, on a tempo sync pattern. Also allows for randomising of volume, pitch, pan, delay, reverse and swing. You decide how much, but not when. You can loop the sequence, change sequence seed with midi keys and quantise the pitch randomising for a more melodic sequence. Works well for random glitchy percussion, instant melodic sequences of multisamples or total chaos. Windows VST.

- https://github.com/ssssam/boucle - an incompetent glitch looper accompanist. Use cases: destructing the boring loops that your drum machine creates (don't let the drum machine discover what you're doing though), beat synced via MIDI, interact with a live instrument performance, although you will have to use a click if you want the beat to be particularly synced, glitching audio tracks in a DAW, record 2 or more loops with stop/start controls and you have a new kinda loop station
