Controller Volume and BPM Not Changing #158

Open DiamondPrime423 opened 2 years ago

DiamondPrime423 commented 2 years ago

So I have my drives connected to the Arduino and they connect and output sound, but I find that some drives are very quiet depending on where they're plugged in to and some songs play a lot slower than it feels like they should play at (like the Tetris one). I tried changing the volume and BPM in the controller but nothing seems to take effect. After I change the BPM, once I hit play it changes back to what it was set to before. Are these things that have to be changed in the MIDI itself?

Floppy drives only have one volume, so the volume control will have no effect on them. Playing a drive with or without a disk, or on different surfaces might make them louder (as floppy drives, being as quiet as possible was a feature, so they'll never be that loud).

MIDI files usually contain events that set the tempo of a song (and can contain many of them if the tempo changes). The BPM slider in the GUI will set the MIDI sequencer to play at a new tempo, but subsequent events in the MIDI file will override that setting. If you'd like to permanently change the tempo of a song, you'll need to edit the MIDI file.

Ah ok, that makes sense. One other question I had was how to connect more than three drives to one Arduino as my board (Arduino UNO) only has 3 ground slots. Is it fine to just attach the ground on other drives to any piece of metal or do I have to get an expander or put more than one in each slot?

The grounds all need to be connected to each other, but you can just daisy-chain wires from drive to drive and then connect the last one to the Arduino.  Or connect all the drive ground wires to a single wire that goes to a single Arduino ground.  "Any piece of metal" definitely isn't a good idea though :P ---- On Mon, 14 Mar 2022 15:44:48 -0700 @.*** wrote ---- Ah ok, that makes sense.
