Wow for all my fascination with tracker music over the years, I never realised they could do this! I would have thought applying a filter would be way too computationally expensive for games from that era! Maybe it's not as expensive as I thought, or there are some really cool programming tricks involved.
And thanks Tenjen for the example! Actually when playing with it, I got the effect I wanted before setting the resonance and cutoff to max & min respectively. But after trying that, the effect sounds really funny and I think it might be perfect for one of my other songs, so I'll try it out there!
I've attached a before and after, the relevant instrument is after the first "verse" of the song, in pattern 4.
It's a song for my new game I'm working on, for the score screen
actually the following trailer is out of date, because it's been renamed to HopSquash! and I'm in the process of replacing the music. The creator of Jump 'n Bump finally got back to me and said I couldn't use any original assets if I'm selling the game! So it's a spiritual successor now instead of an un-official sequel.

It was possible to use the filter at the time , but it's as Saga said , you needed a ''powerful'' processor in order to use it , think at the time was a pentium II 233mhz maybe?
If this was the case then you could use the filter in your tracks no problem , I had a 233mhz in 2002 running fruity loops 3 and made tracks on it , it was tight but it was possible!
As Saga said , no game used it for sure , I personally never played any game back in the days that had this filter thing going on.
You can use the filter in your stuff and you want to use it in the game why not? There's no need to be limited by back in the days standards anymore.
Glad I could be of help.
If you want to do that effect without the filter you would have to just get a synth and make a quick sample of it . Easy as.
Good luck with your game ! I'll have a look at your mod later when I manage to get some free time .
