SamplerBox is an electronic musical instrument. Drop audio samples onto it, hook up a MIDI keyboard, and you'll be able to play with realistic piano, organ, drums, etc. sounds!

The Samplerbox is a small device that plays pre-recorded instrumental sounds when it receives MIDI commands. Vintage products that do this include: ASR-10/EPS/Mirage samplers. Here are other similar products: Sound Modules

It's sample player. It's a MIDI sound module. It is a ROMpler. It stores the sounds of instruments and plays notes from those instruments when it receives MIDI note commands. Those sounds can be any WAV files. You can freely download sound files (samples and sample-sets) over the Internet, or you can record them yourself and copy the sound files into SampleBox. It can then receive MIDI from a MIDI keyboard controller, or any other MIDI device and play the sounds out an ordinary line-out jack.

The original Samplerbox project is described at this website:. https://www.samplerbox.org/ However that's outdated now. We're providing current (May 2023), much easier build instructions at http://chromakinetics.com/samplerbox/. 

Extensive, detailed information on the latest Samplerbox development is at: https://homspace.nl/samplerbox/ Note: this website may be offline. Use the Wayback Machine to view the archived version of that website if necessary. There are a whole lot of pro-level features documented there that you can access, depending on how much complexity you want to deal with.
