Hello, I am trying to track down the origin of the “glitchy note” from the song “Winds of Fjords” by Minomus which got put into Roblox around 2007. Roblox uses Fmod, which Simon Carless told me was originally made for playing tracker files, but despite this, there were numerous playback bugs present when played on Roblox. https://www.youtube.com/watch?v=WNNJt5hI66M Is a video from 2013 that contains the entire song, at 1:08 there is the first playback bug, the song uses Zxx commands to have a lowpass filter on the lead, but it’s not there. Now that is pretty subtle and I haven’t seen anyone else talk about that bug, but the more major bug is at 2:26 where a bunch of T03 commands get played in a row, leading to the “glitchy note” where it’s held for an extremely long time, and I’ve been trying to recreate it in OpenMPT but I keep on getting the tempo wrong. So where could I find a relevant version of Fmod, as the oldest versions available for download are from the mid 2010s and only have a button for importing audio which doesn’t include tracker formats.
Hi you’re talking about an old product called FMOD Ex if you’re talking 2007. After that point several improvements were made to the .IT playback code, and it continues to exist right now in the FMOD Core API part of FMOD Studio.
I think you’re asking if you can play back the songs without code, as thats what the Core API is about, but funnily enough you can test fmod’s .IT playback using our HTML5 examples. See FMOD Examples - PlaySound
If there are any .IT bugs (its been a decade since ive seen one!) i’d be happy to look at the song and fix it. FMOD’s .IT support even supports directx effects (outside of windows - emulated even in the html5 playback) as used in the bejewelled series of games.
