Ah, great! Was gonna try and find what that "Aug '09" project mentioned above might have accomplished (only found this thread here:
https://forum.xentax.com/viewtopic.php?t=3627 - the discussion stops after a first semi-success), and then found this.
Think that's even more than had been expected back then, an external tool with this level of control/options?
A couple questions about this:
1) Is it possible to use this sgt-reading software to compile audio files?
Or export audio files from MxO Music Player somehow (e.g. the sequence selected during a session)?
Recording it from the screen is of course also possible, though right now I'm not quite sure that my OBS Studio (or others I'd tried) records audio without any quality loss - at times it seemed like it did lose quality, so idk.
All the uploads I've found online (2 on youtube, and 1 on soundcloud) use the MxoArchive versions, which contain some errors - would be good to have the correct versions available online as well.
(I.e. they're obviously available via this emu and music tool, but I mean quickly and easily on stream.)
With some of the tracks I'd probably do several ending versions incl. double cuts (since some of these tracks don't have real endings and only really work as loops) - if I'd get around to it that is lol
2) Noticed some occasional mini-breaks in the file/segment transitions with Character, LoadingH, and MisNiobeM - or LoadingH does a clicking sound instead of breaks.
They're relatively rare and irregular, i.e. don't happen on the same spots; sometimes 2/3 times in a row and then nothing for a while etc.
Not sure if it's my system or the app, but thought I'd report on it either way.
The Character, Loading and MisZion/Machines/Merv/Niobe tracks are all without fade-outs of course - so not sure if maybe all the others are also affected by this but it's less noticeable due to the fade-outs masking the slight delays?
Though I didn't notice any rhythmic delays elsewhere.
If any of this ground is already covered by the additional info and links in the OP (the fmod site and the DirectMusic downloads etc.), I was obviously too noob to have understood or noticed lol.
