Ahh, I see the problem now. Thanks... Essentially, the PCM samples(similar to a WAV file) are static(non-updatable), while loadable patches are actually instructions regarding length. frequency, depth,waveform type, etc... to apply to a specific PCM sample... correct?
so in effect, sysex patches do not contain samples themselves, only modifications to existing samples. Hence the word patch... This explains why I can't get WAV output from any Sysex librarian/editor. Essentially, someone needs an MT-32 (or emulator WITH a ROM) in order to make patches, because you are essentially hacking apart a WAV which is not on your computer.
Now, the legal and technical questions that come to mind... I'll understand if all or part of this post gets deleted... But they are questions from someone who does not own an MT-32, and is not willing to obtain a PCM ROM through illegal means...
In theory, if it's just mathematics applied to PCM Waveforms, if someone took a sysex patch, and a recording of a corresponding note of a patch being played, you could obtain the original PCM by reversing the mathematical process... even if the Sysex patch is third party, and in the public domain?
If this is the case, would it not be legal to create the PCM waveforms as a derivitave work of a song created with currently available freeware sysex patches? Or is that entering the realm of unfair usage and reverse engineering?
In other words, is it illegal to release a song containing nothing but unmodified PCM waveforms (through the use of Public Domain sysex patches), regardless of how horrible it sounds? because that is essentially a PCM ROM dump, correct?
As far as I know, users are given the right to distribute music made with an MT-32, without paying royalty to Roland....correct? and I, as a copyright holder am allowed to distribute my music, and allow other users to modify my work as they see fit... Who is the onus on, to make sure that my song doesn't get used as a ROM sample?
