The big deal was latency and jitter the Amiga could not provide that good as the Atari this way with the serial interface. I remember such discussion back in the days. Also the multitasking capabilities of the AmigaOS were to good! Yes, this hindered precise jitter. That is why Steinberg and other sequencer software producers bet on the built in and rock solid Atari Midi implementation. Which meant also a lack of good software for the Amiga then on top of it.
