Abstract
This disclosure describes techniques for processing audio files that comply with the musical instrument digital interface (MIDI) format. In particular, this disclosure describes storage of MIDI parameters for efficient access by a processor and a hardware unit. The processor may be a digital signal processor (DSP) and the hardware unit may be specifically designed to process MIDI parameters. In one aspect, this disclosure provides an apparatus comprising a processor that converts a MIDI event into MIDI parameters, a hardware unit that uses MIDI parameters to generate audio samples, and a plurality of storage units that store MIDI parameters which are accessible by both the processor and the hardware unit.
