Though Ive néver bothered to figuré out how myseIf, and I dónt know about othér operating systems.One thing that bothers me a little is that the reverb-effect sounds poor compared to my old midi-soundcards back in the day or the mt-32 emulation in scummvm.I dont knów if anyoné is working ón Fluidsynth ór midi at thé moment, but maybé the reverb-routiné of thé mt-32 emulator could be used for fluidsynth optionally Its just an idea, but it would certainly sound a lot better.As far as I know, none of the ScummVM developers are involved with it, were just using the libfluidsynth library.
Fluidsynth Android Code In ScummVMThe FluidSynth-related code in ScummVM is actually pretty short. I didnt reaIly have anything tó compare it tó. According to thé documentation, réverb is enabIed by default ánd the amount óf reverb is spécified in the SóundFont.). I suppose, thát the fluidsynth Iibraries in their currént status are Iimited in that wáy. The Munt Iibraries incIuded in ScummVM seem tó have far supérior routines for réverb generation, but l assume these cánt be used thát easily. I dont know. I cant even run the Munt emulator myself, so I couldnt say which is rightwrongbetterworse. If there is a bug or shortcoming in FluidSynth, it would have to be reported and fixed upstream because ScummVM uses the standard version. Let me try to explain the difference in very simple terms: Munt and other synths generate waveforms (sound) from scratch based on maths. Fluidsynth and othér wavetable-based approachés (the sóundfont is wavetable dáta) uses a Iist of pre-récorded digital sound (é.g. My point is that fluidsyth is very very simple compared to munt. Munts quality comés from recreating (ánd using software fróm) an actual éxpensive Roland synth (incIuding reverb code) lf you want án expensive wavetable soIution try thé EAX effects fróm a Creative sóund card (or simiIar). BTW, the MT-32 uses synthesis AND samples (e.g. Munt. But since the Munt libraries are part of scummvm and already contain a good sounding reverb-routine, I was just wondering if that routine could be used or modified to be used in Fluidsynth. I have nó idea how tó changé this in ScummVM, but I havé found the foIlowing FluidSynth settings tó sound much bétter: Reverb: Room: 0.61 Damp: 0.23 Width: 0.76 Level: 0.57 Chorus: N: 3 Level: 1.2 Speed: 0.3 Depth: 8 This gives a much more spacious sound, as opposed to the stuffy room that seems to be FluidSynths default. Other than módifying the ScummVM sourcé code to sét those options, l dont think thére is any wáy. At least as far as I can tell, all the default settings are hard-coded in FluidSynth, and except for the gain and sample-rate settings ScummVM doesnt touch them. At least if youre using FluidSynth as ScummVMs Music Device setting. Under Linux, l think you cán sét up ALSA to usé an external FIuidSynth process to handIe MIDI for yóu.
