## Release notes

### Version 2.1.0 (2026-08-01)

The changes in this release apply to the plugin version only. The DecentSampler version is unchanged.

- Added a translucent overlay graphic on top of the interface.
- Keys that are hovered or held on the keyboard are now shaded in a neutral way instead of turning yellow:
  - White keys turn darker.
  - Black keys turn brighter.
- The computer keyboard keeps playing notes even while you adjust a control with the mouse.
- The dropdown menus inside the interface now use colors that match the instrument.

### Version 2.0.0 (2026-07-19)

- Added a plugin version. See the section "The plugin version".
- Corrected the UI values and the polarity for the drawbars.
- Fixed the mislabeled 5 1/3' drawbar control name.
- Fixed the swapped envelope tooltips on the 16' drawbar.
- Renamed the hidden vibrato control, which was mislabeled "Velocity sensitivity 1".
- Removed duplicated tremolo modulator bindings.
- Removed a dead gain binding in the filter OFF state.

### Version 1.0.0 (2024-08-08)

- First version released

## Included formats

- VST3 (macOS)
- AU (macOS)
- Standalone application (macOS)
- Decent Sampler (macOS, Windows and Linux)

The plugin version is currently released for macOS only.
Windows and Linux versions are planned.
Until then, the Decent Sampler version covers those platforms.

## The plugin version

The plugin is a self-contained instrument, available as VST3, AU and Standalone.
Samples, graphics and impulse responses are all embedded in the plugin itself, losslessly compressed, so there are no external files to install or locate.

The plugin has all the controls and features from the Decent Sampler version, including MIDI learn, the master volume fader with output meter, value readouts for the knobs and full DAW automation.
On top of that, the plugin version adds:

- Drift wheels next to the pitch and modulation wheels, adding a subtle random pitch and volume drift to each voice.
- A velocity curve setting in the settings menu.

## The Decent Sampler version

This version of EDB-Orgel is an instrument preset / sample library for Decent Sampler. If you're new to Decent Sampler, I recommend checking out [this guide][Decent Sampler guide] first.

## Technical specification

|                       | Sample rate | Bit depth | Channels   | Number of files | File size |
|----------------------:|------------:|----------:|------------|----------------:|----------:|

The speed (SPD) and depth (DPT) controls enable you to modulate the amplitude of the drawbars with the desired speed and depth using the Low-Frequency Oscillator (LFO).

- SPD (speed)
  - Tremolo speed determines the speed at which the modulation occurs
- DPT (depth)
  - Adjust tremolo depth to introduce subtle or pronounced variations in volume

### Velocity sensitivity

|![Controls for the velocity sensitivity in the modulation tab](https://benjamindehli.github.io/EDB-Orgel/img/screenshots-velocity-sensitivity.webp)|

## About this repository

This repository contains the source for both the Decent Sampler library (the DecentSampler folder) and the plugin version.
The plugin is a thin wrapper around the shared Dehli Musikk sampler engine, and a converter translates the Decent Sampler library into the engine's native preset format at build time.
The audio files are not part of this repository, since the samples are a paid product.
The full version is available from [store.dehlimusikk.no][Gumroad profile].
