Borg ER-3 is a compact tone generator inspired by the Korg ER-1 percussion synthesizer. It provides a fixed signal path with unusual oscillator controls and an interface designed for immediate experimentation rather than a conventional patch library.
The application allows the waveform and its harmonic character to be manipulated interactively. Its controls are particularly suited to synthetic percussion and electronic sound effects, though the instrument can also produce a range of other electronic tones.
An oscilloscope and editable envelope help connect visual adjustments to the generated sound, making Borg ER-3 an interesting small instrument for exploring synthesis parameters.
This is free and open source software.
Key Features
- Oscillators with frequency, amplitude, resolution and transformation controls.
- Waveforms including sine, slanted sine, square, sawtooth, triangle, impulse and violin-like shapes.
- Mouse-editable amplitude envelope with flexible contour shaping.
- Sequential biquad filter stages with individually adjustable coefficients.
- Oscilloscope display with adjustable zoom.
- Interactive dial controls for immediate changes during sound playback.
- Keyboard and mouse buttons for triggering generated audio.
- Save and load functions for retaining instrument settings.
- Compact graphical interface built using SDL.
