Crackling sound in certain MIDI file
hoshipas.mid.zip -MIDI file, recording of a problem, and a bank file used for recording. Tried playing back this song with a few banks, results were different - some had just a very slight noise (Fat Man 2op), other crackle horribly (attached bank). Number of emulated chips dont matter. Neither does changing the emulation core. I see nothing suspicious with my bank. No idea what is wrong.
Let's check on real OPL3 chip, because there is a similar crap happens with Heretic title theme when playing in OPL3 mode using libADLMIDI even on real OPL3 chip (because of SynthString1 at DMX-family banks)
crackling happens on MIDI ch 0, 1, 2, (contrabass, fiddle, violin instrs. made by me), but who knows, analogous situation may occur here
In case if it turns out to be OPL3 bug, would it possible to add OPL2 mode support?
btw, I tried to play the thing at me (I used default settings), it didn't cause the same mess as you. Which program you had used to play the thing? Which settings mode you had used to play the thing?
SMF-DSP
Are you sure the latest libADLMIDI is bundled? Little note that some older versions of libADLMIDI had the bug because of modulation processing at the real-time API used by SMF-DSP.
BTW, Gonna add the auto-arpeggio flag into VLC plugin...
Are you sure the latest libADLMIDI is bundled?
Well, now checked... it's 9 months old. So, I guess, I must ping @jpcima to update the submodules, if this is the case..
@Wohlstand bad news - on libADLMIDIplay command line library utility, such crap is still there. Even on .wav dump! hoshipas.zip (listen, especially towards the end
Are you sure you played the file with the attached bank file from my zip? 2op Fatman seems to behave kinda properly, for some reason. try bank 72, alternatively (DMXOPL), or 59 (Fat Man 4op).
I still need to try to play the same on a real OPL3 chip, however, the required computer is at another flat yet, probably I'll try to take it on this week.
I recorded the thing using a real OPL3 chip, so, look at the result:

I guess, for the control test I should convert the bank into multiple formats (such as DMX OPL and ASS TMB and try to play the same song via demo tools)
