Vee One is a polyphonic synthesizer and sampler suite for Linux.

It packages three software into one convenient package Synthv1, Samplv1 and DrumKV1. Combining them together gives Linux music producers a plugin that gives them both synth and sampling capabilities.

Synthv1 is a 4-oscillator subtractive polyphonic synth, Samplv1 on the other hand is a digital polyphonic sampler synthesizer. Drum KV1 is an old-school drum-kit sampler.

This plugin works as a LV2 instrument plugin or can also work as a stand-alone Jack client with Jack-session. It also supports ALSA MIDI and Jack MIDI inputs.

This software is free and open source, distributed under GNU General Public License (GPL) version 2 or later.
