What emkay means is you can play the 16-bit notes well, but RMT doesn't support any vibrato or portamento, that's all. A machine language bypass can be used to add vibrato and portamento as well.
To check your FF3 tune I don't get it why you used 16-bit mode, but no 1.79 MHz mode. In fact the HSB values in voice 2 and 4 were put to zero. Normally voice 2 and 4 should be turned on.
No, that's not correct.
Sorry, but ''Overview Orchestra'' should already give much help.

This shows that the FF3 song can be played with Patch 8 without any problem. You don't even need 16-bit notes. A single 8-bit version is possible already. You can use the full 9 octave scale.
It is no problem if you just ask more detailed questions about Patch 8.
