Concept

LinuxSampler was designed as a sampler back-end, decoupled from any user interface. It provides a native C++

based protocol called LSCP for controlling the sampler and managing sampler sessions. Also, there are already two convenient frontends for LinuxSampler, QSampler and JSampler. Due to the decoupled design the sampler can be controlled with the GUI frontend(s) even from another computer, probably even running another OS like Windows or OS X.

, which can be used to edit and create Gigasampler format instruments and can either be used as a stand-alone application or in conjunction with LinuxSampler. The latter case allows to play and edit instruments at the same time, making all modifications with gigedit immediately audible, without having to reload the instruments into the sampler.

Platforms

LinuxSampler, as the name indicates, was originally conceived to run on

Goals

It is planned to support all common sampler formats in LinuxSampler, but at the moment the work is concentrated on the Gigasampler format. Beside that, the goal is to design a new, sophisticated sampler format, more powerful and more flexible compared to any sampler format currently available in the world. There is a feature list with more information about the current development plans available.
