Reaktor MetaSequencer
Originally sold onHeavens*onEarth, Sapphire has been widely acknowledged as the single most powerful MIDI sequencer instrument ever created. Many people have heard it create different musical phrases on the TV series ’30 Something,’ thinking it was a ‘real musician.’ Well, the composer simply set Sapphire up to generate different theme variations depending when he played only two notes.
Briefly, the ensemble’s 16 sequencer channels can intermodulate each other’s notes, velocity, clock rate, and/or bar patterns. Intermodulation can be clocked or single-stepped in layered, fugued, recursive, and 1-shot modes. Other abilities include note filtering and clipping, chord generation, note mapping to musical keys, input recording, MIDI I/O crossmapping, and clock jitter. note sequences to different instruments, and clock jitter control, on the B panelset.
The YouTube video is of Sapphire playing the first snapshot in the ensemble library. The library has many snapshots demoing its various features, all detailed in a comprehensive manual.
