Onyx Arranger is a powerful sequencer program for Windows based on advanced technologies with real-time MIDI data generation and transformation. It combines various features of existing DAW software and thus gives great flexibility for both professional and amateur musicians.

Orchestrator Styles

Tha application allows you to easily convert existing MIDI files to Onyx Orchestrator Style tracks without losing any nuances. These may be later used to generate a new song accompaniment following any chord progressions. You are able to have as many OOS styles per track as you want and they will sound the same in every Chord, Key, Scale and Meter. It is necessary to note that these presets can be merged into clip editing. This means that you have the ability to drag an instrument from one style to another.

Harmonies

What is more, the in-built multimode Harmonizer automatically recognizes the Key and Scale of your tune and calculates a series of high-quality chord sequences for this track in different harmony styles. In addition, it is capable of searching for and sorting the best chord progressions using internal presets. If you want to seamlessly mix several tracks together, you may use such tools as PCDJ DEX and DJ ProMixer.
