LOADING ARCTIC SCREAM…

⚙connection

Connect the FM-1 with a USB data cable, switch it on with Arctic Scream, close other apps that use its MIDI port, then click CONNECT and allow MIDI (SysEx) when the browser asks. Chrome or Edge on a computer. TRY WITHOUT AN FM-1 runs the firmware's own code in this page instead: everything works, nothing is kept.

Sounds and sequences change live, as the knobs do. Writing to the FM-1's memory (STORE, SEND, RESTORE, samples) only happens while it is stopped and silent, and never without you clicking a button.

Click a sound, then LOAD TO a track (or double-click: the selected track). It plays there at once, on the FM-1 too, and the sound page opens on it. RENAME, CLEAR and IMPORT change a user slot here (marked *) until SEND TO FM-1 writes it.

    ♪steps

    Click a step to edit it below; double-click turns it on or off. In the piano roll a click sets a step's note (on the note again: off); drag across steps to draw. Enter notes like C4 or F#3 (C4 = 60).

    ≈samples

    Any WAV (8 to 32 bit, float, mono or stereo, any rate) becomes mono, 22050 Hz, IMA ADPCM, as tools/fm1_sample_upload.py makes it; a slot holds 6.64 s (longer: cut, with a short fade). The root note is C4 unless the file name has one ("drone_A2.wav"). A name is 8 characters (the slot's, what the FM-1 shows): a longer one keeps its number ("Sample-002": SAMP-002). Arctic Scream comes with no samples of its own: the slots are yours. CLEAR ALL SAMPLES empties all four.

    ▤backup

    A backup holds all 64 user sounds, slots A–D and the settings (the same file as tools/fm1_editor_test.py makes). Restoring first makes a backup of what the FM-1 has now (downloaded), then writes everything, then reads it back to check. Samples are not in it: the FM-1 cannot send them back yet; keep their WAV files.
