It allows the assignment of .wav, .aif, and .mp3 files of unlimited size to 72 keyboard keys, with no external devices needed and no MIDI involved. It can be used as a drum pad, to mix together tracks in realtime, to quickly sketch sound designs, or as a performance, installation, or presentation tool.
Because it is not a synthesizer and instead uses your own digital samples (it's a 'software sampler'), Soundplant is a virtually limitless electronic instrument.
A simple graphic interface provides for drag-and-drop, point-and-click configuration of each key, including several options which control the way each sound is triggered, along with pitch, offsets, looping, volume, and panning. Sounds can be easily batch assigned across multiple keys at varying pitches and offsets, and keyboard configurations can be saved and loaded.
