Continuing the theme of musical rather than rhythmic racks this is aquartet of piano, double bass, keys and E flat clarinet all playing in A minor (harmonic). The piano is spread across 3 octaves, the double bass 2, the keys 1 and the clarinet 2. The idea is to have a playable group at your fingertips.
The double bass and clarinet are both from Ableton’s excellent Orchestral Packs. The keys are a mixture of different textural pads for background atmospherics.
These racks are optimised for PUSH but will work on any midi keyboard.
