Maybe 1 or 2 are right, but they sound not SQ3's SysEx instruments. What are you using?
My MT-32 emulator is doing its best to interpret the MT-32's original SysEx parameters to make the identical sounds. Specific documentation on what those parameters mean is hard to come by. I mean, heck, I have 6 manuals that say stuff like "When the TVA Velosity Sensitivity is high the amplitude is greater for higher velocities. When the TVA Velos Sens is low, the amplitude is lower" Of course, nothing more specific than that. No actual formulas or degrees to how much things are affected. What this means in the long run is that slowly, ever so slowly, I am inching my way closer to the correct sounds as I tediously compare the output of my emulator with the output of my MT-32 and try to figure out what the MT-32 is doing differently.
2. Pitch is totally screwy.
No. The pitch is dead on. Getting the pitch right is one of the easiest things since all MIDI devices perform the same way in this department. What's making you think that the pitch is screwy, however, is the lowpass filter that's not interpreting the cutoff frequency and TVF parameters correctly. If I were to disable the lowpass filter (which I have done occasionally to verify other things) you would agree that everything is playing at the right pitch, only then all synthesized sounds would sound much brighter than they should.
Interesting. Nothing special at the moment, but interesting. Good luck with this, this sample's pretty 'interesting' at the moment but keep trying. I'm listening.
Thanks. I'm glad I still have people following my progress. For a little bit of humour, my real sounding board isn't this group, but my wife rather. She couldn't care less about this project and forces me to wear headphones when working on it. Occasionally, however, I'll force her to compare the real MT-32 Monkey Island theme with my version. Its very reassuring to hear even her say I'm getting closer but ultimately its still "too flat" and not quite right. When she says its correct I'll know I'm done. 😜
