Re: Need help to disect some Sysex Messages

this case seem to be easy - there is a simple algorithm that creates PatchTemporaryArea/Bender-range set msgs - and it seems that the calculation is just buggy - sometimes the msg size is wrong and the wrong value is also calculated inside - seem to be some sort of overflow of the logic Oh, yeah. …

time to understand why the game sends this wrong value and the incomplete message Not sure this is possible :) But a few common reasons do exist. Typically, the composer works with a different hardware that may send some bogus data. It may happily remain unnoticed unless it disturbs the audio …

Yes, I mean exactly having a single "init" recording with just SysExes. But that will work if the game only loads custom timbres once at startup, of course. Some games are known to send timbres per tune, and rarely, even while playing a tune.

Great, I'm glad you figured it out. BTW, I have one more tip on MIDI recording. When a game uploads new tones at the very startup only (which is a quite common case), you may make a recording of that timbre bank just once. To make other recordings sound "correct", you may merely prepend that SysEx …

Checked MIDI recorder on Windows and found no problems. Obviously, when I start recording after the initial bunch of SysExes has passed already, the captured MIDI sounds weird. But when I start recording before starting a game, everything is dandy. Maybe ScummVM sends the SysEx bank differently …

Well, if rolling back does not help, it seems that the problem lays in something different. The recordings attached suggest that they are missing SysEx messages that contain custom timbres/patches. I'll double-check if the new version records them correctly, but the old version surely did that.

Hi Mrdangerous, I assume you've missed one way to solve the problem you describe: downgrading the application. Munt version 2.4.0 incorporates a new implementation of the MIDI recording function, so regressions are well possible. To be honest, I only did no more than a smoke test of this particular …

Perhaps, there is a viable alternative already. Quite some time ago, VDMSound on Windows 9x was created, and it proves being workable at least (surely not perfect). Probably, some debugging can make it even better, and may appear faster than creating a new VxD driver from scratch (which is a lost …

Re: Test program for package manager

Yes, obviously every good library code needs testing, and autotests is a great answer to check regressions continuously (provided the tests cover enough corner cases of the library). There is a problem here: nearly every usage of the library involves adding the ROMs, except some pieces of support …
