Thank you for answers.
Differences:
"GS standart" - #121 Fl. Key Click, no Breath Noise tone, cannot initialize GM mode via the front panel, has capital tone fallback
"GS" Control ROM 1.10 - #121 Fl. Key Click, no Breath Noise tone, cannot initialize GM mode via the front panel, has capital tone fallback
"GS" Control ROM 1.20 1.21 2.00 - #121 Breath Noise, Fl. Key Click as a variation tone, cannot initialize GM mode via the front panel, has capital tone fallback
"GS/GM" - #121 Breath Noise, Fl. Key Click as a variation tone, cannot initialize GM mode via the front panel, has capital tone fallback
"mkii" - #121 Breath Noise, Fl. Key Click as a variation tone, can initialize GM mode via the front panel, no capital tone fallback
1. These differences are right?
2. Are any other differences exists?
3. How to test: "Fl. Key Click", "Breath Noise", "reset GS", "reset GM", "Rx GS Reset", "capital tone fallback" ?
4. Are any hardware differences? (yes) Or only Control ROM version? (no) Anybody dumped Control ROM*.bin? Anybody uploaded another Control ROM by yourself? If I will take "GS/GM" version and will upload Control ROM 1.00 into him, then will it become "GS standart"?
