Screen Loader

Turn your pictures or an animated GIF into the SP-404MKII's power-on images and screen saver. It runs in your browser, so your pictures are never uploaded, and it uses Roland's own feature, so no firmware is involved.

Or start from one of ours:

How pictures are sorted
  • One or two pictures on their own become the two power-on images.
  • An animated GIF becomes the screen saver, up to 16 frames.
  • Files named startup_1, startup_2 or screen_saver_1 to screen_saver_16 go exactly there.
  • Everything is fitted onto the 128 × 64 black screen, never stretched.

Pictures are saved as 128 × 64 one-bit BMP files, the format in Roland's SP-404MKII manual (“Customizing the opening screen / screen saver”). Tested on system 5.52. Not affiliated with Roland.
