ReaSynth

Where to get itIncluded with REAPER. It is part of that DAW, not a separate download.reaper.fm

ReaSynth is a straightforward synthesizer that integrates directly into REAPER's FX chain and responds to MIDI keyboard input or the virtual keyboard. It combines fundamental waveforms—square, sawtooth, triangle, and sine—with a classic ADSR envelope to generate subtractive-synthesis tones, making it a practical tool for basic sound design and MIDI-based composition within the DAW.
