Scale-O-Mat 4 is a Max for Live device designed for Ableton Live that allows you to change the musical scale across your entire project seamlessly. It provides musicians and producers with the ability to switch scales and root notes dynamically, making it ideal for both composing and live performance. Whether you're working in film scoring, orchestral arrangements, EDM, drum & bass, or rock, this tool ensures you always play notes that fit perfectly within your chosen scale.

This device offers the flexibility to manage up to four independent groups of scales, chords, or notes, enabling you to experiment with musical harmony and structure. It helps transform random sequences into coherent musical ideas by maintaining harmony across complex arrangements. With access to over 40 scales, including those from popular hardware controllers and curated collections, Scale-O-Mat 4 supports a broad range of musical styles and creative exploration.

Scale-O-Mat 4 includes two key components: the main Scale-O-Mat device and the Instant Scale device. Features like note filtering and pitch adjustments allow you to remove or transpose notes that do not fit the selected scale, ensuring your music stays harmonically consistent. This customized version was developed based on an idea by Tyondai Braxton, offering a unique approach to scale manipulation within Ableton Live.
