  • Notes on SF2/DLS
    Notes on Implementing SF2/DLS Sound Synthesis Daniel R. Mitchell © 2014 Daniel R. Mitchell, All Rights Reserved This document contains copyrighted material and may not be reproduced or distributed in any form without the written permission of the copyright holder. Permission is granted to duplicate, distribute, and implement designs based on this document for any use as long as the copy gives credit to the creator, Daniel R. Mitchell. Sound Bank Instruments SF2 and DLS share a common synthesis model. We will call this a sound bank instrument. A sound bank instrument uses a collection of wavetables and articulation data to define the parameters to the synthesizer. Instrument Overview The top-level structure of a sound bank instrument is shown below. Pitch Wavetable Filter Volume Pan A wavetable oscillator is used to generate the audio signal, which is then passed through a low-pass filter, amplifier and pan control. This is a very generic synthesis structure and can potentially support multiple synthesis algorithms, including additive, subtractive, and sample playback. Typically, only recorded sound playback is used, implemented using a multi-period oscillator with separate transient and steady-state sections. However, a wavetable can be calculated using any of the methods shown in the chapter on complex waveforms, and then added to a sound bank. Each synthesis parameter is a combination of initialization values, internal unit generators, and MIDI channel voice and controller values. Four unit generators are available as inputs to the synthesis parameters. 1. Volume EG 2. Modulation EG 3. Vibrato LFO 4. Modulation LFO Note that DLS1 does not include the modulation LFO.
