Äänimodulit

Äänimodulit, also known as sound modules, are electronic devices that produce musical sounds. They typically do not have their own input controls or a keyboard for direct playing. Instead, they are controlled by external sequencers, computers, or other MIDI (Musical Instrument Digital Interface) devices. These devices send performance data, such as note pitches, durations, and velocities, to the äänimoduli, which then interprets this information and generates the corresponding audio signals.

Historically, äänimodulit were popular for their ability to offer a wide range of sounds without the bulk and expense of a full synthesizer keyboard. They often contained digital samples of instruments, synthesizers, and other sound effects. Early modules were based on analog synthesis, while later ones utilized digital synthesis and sample playback technologies. They found widespread use in home studios, live performance setups, and even in early video game consoles and sound cards for personal computers.

The functionality of an äänimoduli can vary greatly. Some are designed for specific purposes, like emulating particular instrument types, while others are more general-purpose synthesizers. Modern äänimodulit can be hardware units, software synthesizers (often called virtual instruments or plugins), or integrated components within larger electronic instruments. The concept of a sound module continues to evolve with advancements in digital audio processing and synthesis techniques.
