Each to their own here, I find the YM2149 absolutely horrific. Though, I was able to easily reproduced a YM2149 like sound using Logic Pro X's built in Retro Synth for a friend who does like the sound.
Back on topic, none of the Professional Music packages on the Atari wasted time with the Atari's internal audio hardware.
Also we can add Depeche Mode's Ultra to the list of Albums that used an Atari ST for sequencing, as I noticed in a 1997 copy of Future Music.
-edit- actually three STs! Two running Notator and one running Cubase, plus a Mac running logic Pro (which was developed from Natator).
Personally, I feel the same way about the C64s SID chip.
And the OPN2 has a lot of features that Paula lacks.
Later chips like that OPN3 are even more full featured.
But with Yamaha sound chips, it really comes down to which version you are using.
They produced several stripped down chips.
its interesting the bias here.
Yamaha sound chip produce "horrific" sound, but Commodore sound chips are somehow iconic, perfectly silly.
