The FM-1, running SiDJ

This is the same firmware the FM-1 runs, compiled for the browser, with the panel on screen. Switch it on, pick a tune with SELECT and PLAY, and remix it with the keys and buttons. It isn't a recording.

Off. Sound starts when you switch it on.

Songs

These songs are in the emulated FM-1's store, and they stay in this browser. Add .sid files or drop them here. Choose HVSC's Songlengths.md5 first and each file gets its song lengths.

No song lengths loaded.

From your copy of HVSC

Open the C64Music folder of the High Voltage SID Collection to search all of it. Tunes come with their song lengths, and the folder is remembered for next time. This works in Chrome and Edge.

These come with the emulator, and are already in the store on first start.

ASID out

Set ALGORITHM to ASID, or to SID + ASID, and the tune's register writes go to a Web MIDI output. That can be real SID hardware such as a SidStation, a TherapSID, a TeensyROM or a USBSID-Pico, or a soft synth that takes ASID. This needs Chrome or Edge.
