What is JJazzLab?

JJazzLab is a free, cross-platform MIDI sequencer, sampler, and digital audio workstation designed specifically for jazz composition and performance. Developed by jJazzSoft, JJazzLab aims to provide an easy-to-use yet powerful environment for jazz musicians to create and experiment with new musical ideas.

At its core, JJazzLab offers robust MIDI sequencing and editing tools, allowing users to record, edit, and play back MIDI data in an intuitive piano-roll interface. It comes equipped with a library of high-quality virtual instrument sounds like acoustic and electric pianos, bass, drums, guitar, brass, woodwind, and orchestral sections for realistic playback.

Beyond basic MIDI features, JJazzLab has tools tailored for jazz artists. It has an intelligent chord generator and progression composer to quickly create jazz chord changes as a starting point. The lead sheet editor makes it easy to write lead sheets and jazz scores, with options for different notation styles. There is also a melody harmonization feature to harmonize a melody through jazz chord changes.

For live performance, JJazzLab’s phrase pads allow musicians to trigger audio and MIDI phrases in real-time while playing a keyboard. Extensive MIDI assignment functions also allow flexible computer control options suited for live playing.

As a digital audio workstation, JJazzLab supports recording and editing audio tracks along with MIDI. It comes with a suite of native effects like EQ, compression, reverb, and more for polishing recordings. The audio engine can handle large multi-track sessions with high sound quality.

JJazzLab is available free for Windows, macOS, and Linux. With its lightweight footprint and jazz-centric tools, JJazzLab aims to be the ideal scratchpad and accompaniment tool for both students learning jazz and advanced musicians exploring new compositional ideas.
