samplv1
What it is
samplv1 is a free, open-source polyphonic sampler synthesizer for Linux with stereo effects. It runs as a standalone JACK client supporting JACK-session and NSM session management, and accepts MIDI through JACK MIDI or ALSA MIDI. It is also available as an LV2 instrument plugin. The project is licensed under GNU GPL version 2 or later and lists a free plan. The home page lists version 1.5.0, released September 15, 2026, with a factory and community presets install package and updated theme options. Qt and libsndfile are required to build and run it. JACK, ALSA, LV2, FFTW3, Rubber Band, and liblo are optional build components; liblo is needed for NSM support. CMake build instructions use /usr/local by default. Settings are stored in the user configuration directory. The project says bugs remain but describes a production and stable phase.
