The PCM 'instruments' still don't properly mad any other soundfonts than the MSGS soundfonts. If I try a GM compatible soundfont on SPC700, it doesn't sound anything like I want it to.

And no, importing random SPC instruments into each instrument slot doesn't count, although I wish WAV support for SPC700 was a thing.

Basically, Soundfont ( and WAV too ) is not suitable for SPC700 spec. Just because it supports WAV does not make it good.
Please be sure the following.

・SPC700 is ADPCM. If the PCM data is not well for ADPCM, the sound will be dirty. And Looping will not work either.
・Loop point is force 16 bytes aligned.
・If BaseFrequency is other than 500hz , sound is not good.

I recommend using some kind of BRR PCM editor.
