The Important stuff

Controller — A controller is a device designed to control electronic instruments, software, and hardware without generating sound on its own. It sends performance and control data, allowing parameters such as notes, velocity, modulation, and automation to be played or adjusted in real time. Controllers are central to hands-on workflow, enabling expressive control in both studio production and live performance.. Keyboard — Keyboard refers to electronic keyboards used for playing, composing, and performing music, ranging from simple digital keyboards to advanced synthesizer-based instruments. On SynthForSale, keyboards include instruments designed for studio production, live performance, and home use, often featuring velocity-sensitive keys, built-in sounds, MIDI connectivity, and integration with computers and other hardware. They are commonly used across electronic, pop, ambient, film, and experimental music, and can function as standalone instruments or as controllers for software and modular setups.. MIDI — MIDI is a digital control standard used to transmit performance and control data between electronic instruments, computers, and hardware devices. It carries information such as note data, velocity, timing, and parameter changes rather than audio, allowing instruments and software to communicate, stay in sync, and control each other. MIDI is fundamental to modern music production, sequencing, and live performance setups.. Used — Synth for Sale has over 1000 used synths and gear like that for sale.
