Okay, so turbo mode will be convenient (shift-click green flag). (Don't complain about it glitching out or being too slow if you're not using turbo mode.) Just click and drag your mouse around do whatever you want. Then close your eyes and listen. You MUST close your eyes. (haha jk) Changing instruments and tone is pretty self-explanatory. Click the button, then use arrow keys. Drag left/right to adjust volume and tempo.
EDIT: 6/25-Thanks DJ-stickman for curating this! -Also, I fixed the bug where the tiles weren't producing different tones. This is SoundSurge. The awesome tone-producing field, customizable to make the perfect sounds. No music skills required. Just click anywhere. Shake your mouse violently. Draw a pretty picture. It will make a pleasant melody. Enjoy! Find any bugs? Just tell me below. Please include what is wrong, how to reproduce it (if available), and the player used. The more bugs you tell us, the more we know about. The more bugs we know about, the more we can fix. The more bugs we fix, the more pleasant experience you will have! Thank you for your cooperation. This was created by ProgramCAT and kayybee. Please do not directly copy it, but feel free to remix it. Thanks :) Huge thanks to ProgramCAT. I don't think he's active anymore, but he helped a lot with the project. New in v2: "Clear" and "Fill" buttons. Careful with the fill! Warning: LAG! Tempo range increased Instruments updated to 2.0, different instruments, correct this time! Current Bugs: Suggestions: Multiple Instruments Simultaneously-maybe? Pause Feature-maybe? More instruments-most likely
