- https://en.wikipedia.org/wiki/SoundFont - a brand name that collectively refers to a file format and associated technology that uses sample-based synthesis to play MIDI files. It was first used on the Sound Blaster AWE32 sound card for its General MIDI support.
MIDI files in themselves don't contain any sounds, rather they contain only instructions to render them. To render such files, sample-based MIDI synthesizers use recordings of instruments and sounds stored in a file or ROM chip. SoundFont-compatible synthesizers allow users to use SoundFont banks with custom samples to render their music. A SoundFont bank contains base samples in PCM format (similar to WAV files) that are mapped to sections on a musical keyboard. A SoundFont bank also contains other music synthesis parameters such as loops, vibrato effect, and velocity-sensitive volume changing. SoundFont banks can conform to standard sound sets such as General MIDI, or use other wholly custom sound-set definitions.
The original SoundFont file format was developed in the early 1990s by E-mu Systems and Creative Labs. A specification for this version was never released to the public. The first and only major device to utilize this version was Creative's Sound Blaster AWE32 in 1994. Files in this format conventionally have the file extension of .SBK or .SB2.

- SoundFont | Dungeon Keeper Wiki | Fandom - SoundFont is a brand name and file format for sample-based MIDI synthesis instruments. It was originally developed by Creative Labs and Emu-Systems. Dungeon Keeper utilises SoundFont technology to produce atmospheric sound effects. Bundled with the game are three .sbk files (sbk standing for SoundFont Bank): bullfrog.sbk, atmos1.sbk, and atmos2.sbk, each containing dungeon-themes wave files. These are used as instruments for music.dat (which is actually a MIDI file and has nothing to do with the game's soundtrack, which is in Red Book format (played from the CD)). If the game detects a Sound Blaster AWE32 or AWE64, one of the SoundFont banks is loaded at random and the MIDI tune plays, and the player is greeted by drops, screams, and other dungeon-themed sounds upon starting a game. It is for this reason that 'Creative AWE32 or AWE64' is the only MIDI option available in the DOS version.

- https://en.wikipedia.org/wiki/REX2 - a proprietary type of audio sample loop file format developed by Propellerhead, a Swedish music software company. It is one of the most popular and widely supported loop file formats for sequencer and digital audio workstation software. It is supported by PreSonus Studio One, Propellerhead Reason, Steinberg Cubase, Steinberg Nuendo, Cockos REAPER, Apple Logic, Digidesign Pro Tools, Ableton Live, Cakewalk Project5, Cakewalk Sonar, Image-Line FL Studio, MOTU Digital Performer, MOTU Mach 5 (software sampler), and Synapse Audio Orion Platinum, among others.REX files are named after the three-letter filename suffix for "ReCycle EXport," as these are files generated by Propellerhead's ReCycle looping utility. The filename extensions for the file format are .rex and .rx2.
SoundFont 2.0 was developed in 1996. This file format generalized the data representation using perceptually additive real world units, redefined some of the instrument layering features within the format, added true stereo sample support and removed some obscure features of the first version whose behavior was difficult to specify. This version was fully disclosed as a public specification, with the goal of making the SoundFont format an industry standard. Files in this and all other 2.x formats conventionally have the file extension of SF2.

- The SFZ Format - The SFZ Format is widely accepted as the open standard to define the behavior of a musical instrument from a bare set of sound recordings. It was created by René Ceballos (founder of RGC Audio™) and is now maintained by Cakewalk™. Being a royalty-free format, any developer can create, use and distribute SFZ files and players for either free or commercial purposes. The SFZ format consists of one or more text files a set of sound sample files. Comes in SFZ 1.0 and SFZ 2.0 varieties.

MT Power Drum Kit
- MT Power Drum Kit Sampler - a free drum sampler offering the powerful, high-quality sounds of an acoustic, realistic drum kit. Samples have been specially recorded and processed to make them ideally suited for use in pop, rock and metal productions. The MT Power Drum Kit Sampler differs from other, expensive drum samplers in that we have already pre-processed the sounds with compressors and EQs to make them a perfect fit for any mix. This is precisely where many drum sample programs fail. Some of the expensive plugins available on the market deliver a highly natural and dynamic drum kit sound as a solo instrument, but many fail as soon as they are supposed to be used for a complete mix in a powerful pop or rock production. Either the kick drum suddenly sounds much too slack or fuzzy in the mix, or the snare drum, which initially sounds natural and dynamic in solo mode, suddenly gets lost in the background in the overall mix, drowned out by the guitars and other instruments. But this is exactly where the MT Power Drum Kit is strongest. Its kick and snare drums come through clearly in any mixing situation – and still sound natural and not overly compressed.
Players / libraries
- LinuxSampler - modular design, decoupled from any user interface. LinuxSampler itself usually runs as own process in the background of the computer and usually does not show up anything on the screen, or at most it can be launched to show status informations and debug messages in a console window.
- LinuxSampler Control Protocol - Main focus of this protocol is to provide a way to configure a running LinuxSampler instance and to retrieve information about it. The focus of this protocol is not to provide a way to control synthesis parameters or even to trigger or release notes. Or in other words; the focus are those functionalities which are not covered by MIDI or which may at most be handled via MIDI System Exclusive Messages.
- Qsampler is a LinuxSampler GUI front-end application written in C++ around the Qt framework using Qt Designer. At the moment it just wraps as a client reference interface for the LinuxSampler Control Protocol (LSCP).
- JSampler is an opensource, platform-independent, GUI front-end for LinuxSampler, written entirely in Java. The main goal of the JSampler's design is to be extensible and more flexible regarding the integration of different GUI implementations. JSampler consists of two parts: JSampler core - handles the LSCP command processing and event notifications, sent by LinuxSampler, and provides convenient data models and controllers to be used instead. The core also provides the necessary interfaces that should be implemented by all JSamler views. JSampler view - an extension to the JSampler core, which provides the user interface part of JSampler.
- https://sourceforge.net/projects/ls16/ - a convenience front-end to LinuxSampler, featuring 16 sampler channels with configurable MIDI inputs and one stereo audio output.
- https://sourceforge.net/projects/qgiged/ - a sampled instrument visual editor for LinuxSampler.
- FluidSynth - A real-time software synthesizer based on the SoundFont 2 specifications. It can be used for live audio synthesis of MIDI events or for rendering MIDI files to disk, using SoundFont instruments. It can also be embedded in other applications. This is not a application with a graphical user interface, however there are several GUI applications which utilize FluidSynth.
- Qsynth - Qt GUI Interface for FluidSynth
- EMAP (Easy Midi Audio Production) - a graphical user interface for the fluidsynth soundfont synthesizer. It functions as a Jack compatible 1) stand alone application (gtkmm) or 2) an lv2-plugin (gtk2 or gtk3) that can be used inside any lv2 host such as ardour and qtractor. EMAP is meant to be a simple alternative to the popular qsynth UI and puts a majority of the control of the fluidsynth into the hands of the connected midi device. It is especially useful for working with a large collection of soundfonts.

- http://freshmeat.sourceforge.net/projects/gluid - a very small graphical interface to fluidsynth with minimal features. It runs in the system tray. It allows you to set the audio and MIDI drivers, toggle reverb and chorus, and start fluidsynth. 2009
- fluadity - Synthesiser and midi-to-wav converter using the Fluidsynth library. The name fluidity would be a great variant on timidity (which in turn is a magnificent variant of audacity), but 'fluidity' is already a one-person Nintendo video game, released 6dec2010.
- fluidsynth.lua - a Lua interface to the fluidsynth library
- https://github.com/divideconcept/FluidLite - Very light version of FluidSynth designed to be hardware, platform and external dependency independant.
- DrumGizmo is an open source cross-platform drum plugin and stand-alone application. It is comparable to several commercial drum plugin products. Features include: Stand-alone, Lv2 and VSTi versions available. Open drumkit file format, allowing the community to create their own drumkits. Drum velocity, allowing for several different hit velocities for each drum. Multichannel output, making it possible to mix it just the way you would a real drumkit. Optional built-in humanizer, analyzing the midi notes, adjusting velocities on-the-fly. Stand-alone midi renderer, generating .wav files, 1 for each channel. Stand-alone midi input, making it possible to use DrumGizmo as output for an electronic drumkit.

- https://github.com/jmage619/jmage-sampler - a Linux based sampler. It can be run as stand alone JACKapplication or as an LV2 Plugin. The goal of JMAGE Sampler is to be able tocreate many zoned, multi layered patches quickly from scratch, with all thecontrols up front and tweakable in real time.What JMAGE Sampler is NOT is a disk streaming sampler. All samples are loaded inmemory. JMAGE Sampler can read SFZ files, but only parses the fields itcurrently supports. There are NO guarantees that an arbitrary SFZ file will notcrash the sampler, especially if the patch is intended for disk streaming.Patches can be saved in SFZ or JMZ format, an extension to SFZ that also storesJMAGE Sampler specific fields. JMZ should be preferred for normal usage.

- SynthFont - a commercial program for editing and playing midi files using various sound source files like SoundFonts, GigaSampler files, SFZ files and more. VST instruments can also be used instead of a sound source file. A midi file is different from - for instance - a MP3 file in that the file does not contain any audio data. The file is a collection of notes and instructions for how to play them. SynthFont combines this data with the audio data in a SoundFont to produce ("render") an audio version of the song. - $
