Tip: Do NOT use TMIDI Player, especially if you want to align tracks, even if it supports it. Was forced to realign an audio render section-by-section earlier today. A new reason to dislike TMIDI Player apart from looking atrocious.
Falcosoft MIDI Player is great, but it can only handle a single port well. DearHoney uses MIDITrail as well for multi-port SMFs, maybe that's the answer for that use case... Octavia Dirigere soon™.
