Quantum Leap Stormdrum 2 Pro Bundle from EastWest is a virtual instrument, featuring 4GB of additional samples in addition to the original 12GB of Stormdrum 2’s various acoustic percussion instruments, ranging from ethnic drums to found-sound percussion. Included are over one-hundred film-score-oriented MIDI performances, which allow for changing tempo, tuning individual instruments, and altering the performances, all without audio degradation. Each one includes dozens of variations, intros and endings.

This collection is a follow up to the hugely successful Stormdrum, featuring over twice the content and a built-in dedicated playback engine, Opus, which provides an easily searchable browser and the ability for users to audition and customize the sounds. All the sounds were recorded using vintage Neumann microphones in EastWest’s Studio 1.

The MIDI performances are in type-0 MIDI-file format, meaning that the sixteen tracks of MIDI data are compressed into a single MIDI file data stream. Data can be played back as is, or expanded to sixteen tracks using the expand/unpack function in a sequencer. Once a template is set up, access is available to every parameter of the sequence. Tempo changes, muting instruments, adding instruments and parts, and changing the tone using velocity or controllers (quantizing etc.) are all possible.
