Instruments

Instruments are the collections of sounds in Online Sequencer, which have different timbres and applications within the music. On the sequencer's piano roll, instruments are distinguished by their color. While Online Sequencer has 72 notes, the majority of Online Sequencer's instruments cannot play this entire range. Therefore, only instruments like pianos, vibraphones, music boxes, sitars, steel drums, and the 2023 drum kit can play all notes. There are currently 56 unique instruments arranged in 6 categories.

Instruments can me modified using their options and Clones can be created for different option configurations using the same instrument.
