The Sound FX Kit is a comfortable Commodore 64 sound effects editor, published in the May/June issue of Commodore Disk User, sold for £2.75.

At its core, you create up to 32 sound effects, each of which occupies a single SID channel. On every creation, you set the SID registers, and optionally:

Enter a title
Gate off at given time
Add pulse width modulation at variable rate, within fixed bounds
Add pitch bend that either wraps, stops at gate-off, or reverses at gate-off and then wraps
Add one of four pseudo-random generators

Not supported are combined waveforms, combined hard sync and ring modulation, and filters.

Furthermore, you can build up to 50 complex sounds, namely by mixing up to three out of the 32 core sounds together, and print the core numbers for the game programmer.

On the side, you can maintain libraries of 100 sounds. The disk includes 57 example sounds, mainly titled after science fiction, engines, guns, and adjectives like miscellaneous and weird.
