Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

CLever Audio Plug-in or CLAP is an open source software architecture, application programming interface and reference implementation suite for audio effect plugins as used in multimedia software such as digital audio workstations, audio editing software, and video editing software with integrated audio workflows. The specification and reference implementation was released in 2022 by the Berlin-based audio software companies u-he and Bitwig.[2][3][4]
CLAP was created as an open licensed alternative to proprietary audio plugin formats[5] such as Steinberg's VST format, Apple's Audio Units format, or Avid Technology's Avid Audio Extension (AAX) format, designed for non-destructive parameter automation, multi-voice envelopes, true MIDI 2.0 support, better multi-core CPU performance and greater ease writing plugins in a non-proprietary licensing framework under the MIT License. CLAP is supported by 15 DAWs[6] and 93 plugin producers[7][8] who have produced 394 CLAP plugins.[9]

The Linux Audio Developer's Simple Plugin API (LADSPA) is an application programming interface (API) standard for handling audio filters and audio signal processing effects, licensed under LGPL-2.1-or-later. Originally designed through consensus on the Linux Audio Developers mailing list, it now works on a variety of platforms. It is used in many free audio software projects, and there is a wide range of LADSPA plug-ins available. LADSPA exists primarily as a header file written in the programming language C. There are many audio plugin standards and most major modern software synthesizers and sound editors support a variety. The best known standard is probably Steinberg's Virtual Studio Technology. LADSPA is unusual in that it attempts to provide only the "Greatest Common Divisor" of other standards. This means that its scope is limited, but it is simple and plugins written using it are easy to embed in many other programs. The standard has changed little with time, so compatibility problems are rare. DSSI extends LADSPA to cover instrument plugins. LV2 is a successor, based on LADSPA and DSSI, but permitting easy extensibility, allowing custom user interfaces, MIDI messages, and custom extensions.
MusE is computer software, a sequencer for Musical Instrument Digital Interface (MIDI) and audio, with recording and editing abilities. It was originally written by Werner Schweer and now is developed by the MusE development team. It is free software released under GPL-2.0-or-later. MusE aims to be a complete multitrack virtual studio for Linux. As of 2020, it has no support under other platforms as it relies on Linux-only technologies, such as Advanced Linux Sound Architecture (ALSA). It also supports the Linux Audio Session Handler (LASH). For version 0.7, the music notation feature was removed from MusE; this code later became the cross-platform notation app MuseScore Studio. A scoring feature returned to MusE in version 2.0. From version 2.2 MusE supports the LV2 audio plugin format and the formerly supported Linux Audio Developer's Simple Plugin API (LADSPA), Disposable Soft Synth Interface (DSSI), and Virtual Studio Technology (VST). From version 4.0 a redesigned user interface has been added.
A MIDI keyboard or controller keyboard is typically a piano-style electronic musical keyboard, often with other buttons, wheels and sliders, used as a MIDI controller for sending Musical Instrument Digital Interface (MIDI) commands over a USB or MIDI 5-pin cable to other musical devices or computers. MIDI keyboards lacking an onboard sound module cannot produce sounds themselves, however, some models of MIDI keyboards contain both a MIDI controller and sound module. When it is used as a MIDI controller, MIDI information on keys or buttons the performer has pressed is sent to a receiving device capable of creating sound through modeling synthesis, sample playback, or an analog hardware instrument. The receiving device could be: a computer running a digital audio workstation (DAW) or a standalone audio plugin (alternatively, the computer could be used to re-route the MIDI signal to other devices) a sound module a digital (digital piano/stage piano) or analog (synthesizer) hardware instrument with MIDI capability, such as a drum machine While many digital and analog hardware keyboards in the aforementioned categories of digital piano, stage piano, and synthesizer can be used as MIDI controllers if they have MIDI capability, they often do not offer the same level of software integration and number of MIDI-mappable controls as a dedicated MIDI keyboard. MIDI keyboards are often utilized by individuals who work with DAWs and software instruments, from hobbyists to professional musicians working in recording studios or concert stages.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
