Electrosound 64 is a Commodore 64 music editor. It was only sold in the UK, but got spread to a few Dutch scene members. It was used in many demos and games in 1986 and even got a nickname, Leccysound, but it was largely superseded by Soundmonitor after a year.

An arranger can fill 20 sequences with up to 240 notes. In each sequence, you can choose a tempo and 3 (one per SID voice) out of the 10 instruments. These 3 instruments stick for the rest of the sequence, except that whenever a voice can rest, you can insert a drum sound (out of 24, which however cannot be modified). The sequences can finally be repeated and linked to each other in a track, similar to the later MOD format. One music file stores 5 tracks (songs).

10 instruments can be defined. Per instrument, you can set all SID chip registers, but also add modulations: pitch, pulse width, cutoff frequency, restarting the ADSR on a new note, and restarting the ADSR regularly. There is only one delay for all modulations, but separate speeds (often near 99), depths, partially shuffle option, and trigger condition for each modulation. Trigger condition A is that the respective modulation is restarted only on the first note after a rest, and B is that the modulation is restarted on every note.

To deliver a soundtrack, the arranger starts up a separate compiler program, loads the entire music file, optionally up to 2 instrument-set files (for use as 20 sound effects, triggerable on any of the 3 voices), enters a start address (dictated by the game programmer), and saves a file with the optimized data and code. The usage was a bit complicated, though, and required people to redefine the coarse tempos in the game. Also, despite its power, the driver is badly programmed and its CPU load still cursed.

Rob Hubbard found most editors too limited, but liked Electrosound 64 the most out of them.
