Tonmeister is a MIDI effect plug-in designed to constrain incoming MIDI notes to a chosen scale and root key, ensuring your melodies and harmonies stay perfectly in tune. It also offers the ability to generate chords from single incoming notes, enriching your compositions without needing extra input. The root key can be automatically determined based on incoming MIDI data, simplifying the process of transposing and maintaining musical coherence.

While Tonmeister is crafted as a complementary tool for WOK's CLOCKWOrK step-sequencer, it functions effectively as a standalone plug-in. This flexibility allows users to enhance their MIDI workflow with precise scale enforcement and chord generation, whether integrated within a sequencing setup or used independently within any digital audio workstation.

Tonmeister supports individual setting of MIDI channels for input notes, automatic root key detection, and output, giving users detailed control over MIDI routing and processing. Its straightforward interface and focused functionality make it an ideal tool for producers and musicians aiming to streamline their MIDI performances and compositions with musical accuracy.
