Frap Tools USTA Voltage Score

USTA is a 44 tracks sequencer for voltages and gates with variable stage duration, designed to quickly see and edit multiple voltage relationships in real-time.

Variable stage duration means that every single stage duration can be individually set in relation to the clock, instead of being constrained to a one-to-one ratio (i.e. one stage per every clock impulse).

44 tracks means that every stage can store and generate up to four separate voltages (two CVs and two gates) and that up to four independent stage sequences can be arranged into as many different tracks.

Its architecture is based on an array of 16 Stages which form a Pattern; 16 patterns form a Track, and four tracks form a Project. Within each track, each stage can provide two gates and two CVs, and a wide set of options is available to define and modify the value of each output (Layers) and the way it is played (Colours).

Every Stage is related to a dedicated steppe
