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. ### Version 2.0.0 (2026-07-19) - Added a plugin version. See the section "The plugin version". - Adjusted the gain levels and the keyboard color. - Fixed the value for the modulation wheel binding. - The filters now use translation tables and the correct state names. - Fixed the default value for the LFO. - Effect bindings now use effectIndex. - Removed wrong sampleRate attributes from the sample definitions. ### Version 1.0.0 (2023-10-16) - 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 Strykebrett 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 | |----------------------:|------------:|----------:|------------|----------------:|----------:| | **Samples** | 44.1 kHz | 24 bit | 1 (mono) | 121 | 171.7 MB | | **Impulse responses** | 48 kHz | 24 bit | 2 (stereo) | 4 | 3.6 MB | ## User Interface |![User interface for the "Strykebrett" library](https://benjamindehli.github.io/Strykebrett/img/screenshots-strykebrett.webp)| |:--:| |User interface for the "Strykebrett" library| Six drawbars feed an envelope, amplitude modulation with LFOs, highpass and lowpass filters, velocity and dynamics, oscillator drifting, and the ensemble, phaser, echo and reverb effects. ### Mixer (Bass / Treble) |![Drawbar controls for the bass and treble section of the keyboard](https://benjamindehli.github.io/Strykebrett/img/screenshots-mixer.webp)| |:--:| |Drawbar controls for the bass and treble section of the keyboard| Each of the six drawbars sets the level of one octave or sound. ### Voltage Controlled Amplifier (VCA) |![Envelope and LFO controls for the voltage controlled amplifier](https://benjamindehli.github.io/Strykebrett/img/screenshots-vca.webp)| |:--:| |Envelope and LFO controls for the voltage controlled amplifier| #### ADSR Envelope - Attack - Individual attack time of the amplitude envelope for four of the drawbars - Decay - Individual decay time of the amplitude envelope four of the drawbars - Sustain - Individual sustain level of the amplitude envelope four of the drawbars - Release - Individual release time of the amplitude envelope four of the drawbars #### Low-frequency Oscillator (LFO) The Rate and Depth knobs enable you to modulate the amplitude of four of the drawbars with the desired depth and rate using the Low-Frequency Oscillator (LFO), opening up a world of rhythmic possibilities. The LFOs for the treble section has a sine waveform for smooth transitions. The LFO for the bass section has a sawtooth waveform for a rhythmic effect. - Rate - LFO rate determines the speed at which the modulation occurs - Depth - Adjust the LFO depth to introduce subtle or pronounced variations in volume ### Voltage Controlled Filter (VCF) |![Controls for the highpass and lowpass filters](https://benjamindehli.github.io/Strykebrett/img/screenshots-vcf.webp)| |:--:| |Controls for the highpass and lowpass filters| Strykebrett has a highpass filter and a lowpass filter. The highpass filter ranges from 20 Hz to 2000 Hz and the lowpass filter ranges from 200 Hz to 8000 Hz. - On / Off - Turns on or off the filter - Freq - Cutoff frequency for the filter - Res - Amount of resonance at cutoff frequency ## Oscillators |![Button controls for the oscillators](https://benjamindehli.github.io/Strykebrett/img/screenshots-oscillators.webp)| |:--:| |Button controls for the oscillators| - Dyn - Turns on or off the velocity controlled amplitude - Drift - When enabled, each sample will have a slight pitch drift. The pitch drift for each sample is unique and independent. It's less pitch drift in the bass samples than the treble samples. ## Ensemble |![Button controls for the ensemble effects](https://benjamindehli.github.io/Strykebrett/img/screenshots-ensemble.webp)| |:--:| |Button controls for the ensemble effects| - O - 3 stereo choruses with different speed and depth - Acc - Turns the ensemble off - Solo - Fast stereo vibrato - Organ - A slow stereo chorus ## Effects The phaser is a built-in effect. The echo and reverb effects are achieved using carefully crafted impulse responses. The echo effect employs a Fulltone Tube Tape Echo recorded twice for stereo, while the reverb effect draws from a Chase Bliss Audio & Meris CXM 1978 reverb pedal with a room setting. ### Phaser |![Controls for the phaser](https://benjamindehli.github.io/Strykebrett/img/screenshots-phaser.webp)| |:--:| |Controls for the phaser| - On - Turns the phaser on and off - Color - Adds more feedback to the phaser - Rate - Adjust the rate of the phaser modulation ### Echo |![Controls for the tape echo impulse response](https://benjamindehli.github.io/Strykebrett/img/screenshots-echo.webp)| |:--:| |Controls for the tape echo impulse response| - On - Turns the echo on and off - Long - Switches between a short slapback echo and a long echo with slow repeats and high feedback - Mix - Mix between direct signal and echo signal ### Reverb |![Controls for the room reverb impulse response](https://benjamindehli.github.io/Strykebrett/img/screenshots-reverb.webp)| |:--:| |Controls for the room reverb impulse response| - On - Turns the reverb on and off - Long - Switches between a short/small room reverb and a long/big room reverb - Mix - Mix between direct signal and reverb signal ## 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].
