This is straight out of the computer.

I am not getting any problems when using DAW apps. I can easily achieve realtime audio with a combined latency (input + output) of 3 ms.

So for example, playing a bass guitar into a DAW, using VST plugins for amplifier and cabinet simulation and monitoring the output via headphones with the built-in audio device of the iMac is possible without perceived latency.

This is what surprises my so much regarding my problem: In my case, BIAB doesn't have to react to real time input. I am not sending MIDI notes to the program or playing anything live. The program just plays back a sheet of chords. It can use an output buffer even as long as 5 seconds, since the audio and visual data is completely predictable. I would even be willing to wait 10 seconds to pre-render the whole song! This is not a high performance use case.
