The "Day of the Tentacle" intro sounds strange in ScummVM

Question

ScummVM has had support for FluidSynth for quite some time now. Most things I've tried have sounded pretty good, but the intro to the game Day of the Tentacle sounds wrong. It's always difficult to describe sounds, but there's a kind of "boooiiing" sound at the very beginning, where it bends the pitch of a note. The problem is, it isn't bent as far as if I use my sound card's built-in MIDI synth.

I've mostly tried it in FluidSynth 1.0.7, but I believe it also happens in 1.0.8. At first, I thought I had made a programming error with libfluidsynth, but it also happens if I hook up fluidsynth as an ALSA sequencer, and play it through that.

There is a [demo version] of the game that can be used for testing.

Answer 1

That is news to me that ScummVM even used FluidSynth. Nice to know! I gave that demo a try. First problem is that I'm not sure what I'm supposed to hear, since I've never played Day of the Tentacle before. Does ScummVM use FluidSynth by default? Any ideas where it gets its instruments from (is there an embedded SoundFont in the program, or does it hook into the SoundFont loader API of FluidSynth?)

If you could supply any of the following, it would likely help quite a lot:
- A recording of a proper playback of Day of the Tentacle
- Any info on how ScummVM uses FluidSynth (how instruments get loaded)
- Captured MIDI output of ScummVM with DOTT

I could probably capture the MIDI via the ALSA sequencer myself, if need be.
