Shorthand

• SER = Macintosh SERial MIDI path · SMI = OMS Standard MIDI Interface
• OMS = Opcode Music System · FM = MOTU FreeMIDI · MTP = MOTU MIDI Time Piece
• MTS = MOTU MIDI Time Stamping · AMT = Emagic Active MIDI Transmission · LTB = Steinberg Linear Time Base
• MTC = MIDI Time Code · DTL = MOTU Direct Time Lock · FSK = Frequency-Shift Keying
• LTC = Linear Time Code · VITC = Vertical-Interval Time Code · WC = Word Clock · MMC = MIDI Machine Control
• MTS / AMT / LTB · compatible software required · OMS alone ≠ proprietary timestamp scheduling
• USB / Classic Mac OS · no modern generic class-compliant path · vendor driver + OMS / FreeMIDI / vendor layer normally required

Appendix A — Macintosh serial-port restoration / host adapters

Year	Manufacturer	Model	Connection	Ports	MIDI relevance
1999	Keyspan	SX PRO Serial Card	PCI → RS-422	4× Mini-DIN-8	1 Mbps/port; manufacturer explicitly advertised support for selected MIDI peripherals
1999-01	Griffin Technology	gPort	internal modem connection → Mac serial	1× serial	Announced for the blue-and-white Power Mac G3; maker explicitly included MIDI devices. Distinct from iPort and from USB-to-serial adapters.
1999/2000	Keyspan	USA-28X / Twin Serial Adapter	USB → serial	2× Mini-DIN-8	works with some serial MIDI systems but compatibility is device-specific; forum reports MTP AV better than Studio 5
1999	GeeThree	Stealth Serial Port	internal modem slot → RS-422	1× Mini-DIN-8	restores a native-like externally-clockable serial port on supported B&W G3/G4/iMac models; useful for legacy MIDI
1999/2000	MegaWolf	Remus/2 · Romulus/4 · Rufus/8	PCI → serial	2 / 4 / 8 ports	PCI serial expansion used for legacy MIDI; forum warns some MegaWolf configurations are FreeMIDI-oriented rather than universal OMS replacements

USB/PCI serial adapters are device-specific. Emagic Unitor-family serial operation requires external clocking; Keyspan USB Serial Adapter and Griffin iPort are not substitutes for the Unitor serial connection. Original Unitor8 has no USB host port.

Appendix B — FireWire / mLAN: MIDI inside multifunction audio/network hardware

Year	Manufacturer	Model	Host	MIDI	Classic Mac OS	Notes
~2000	Yamaha	mLAN8P	IEEE-1394 / mLAN	MIDI + audio over mLAN; physical MIDI I/O	8.6–9.2.2 forum report; mLAN driver ≤1.04 + mLAN Mixer	first-generation mLAN; not a MIDI-only interface
2004	Yamaha	i88X	IEEE-1394 S400 / mLAN	mLAN MIDI ports + physical MIDI I/O	9.2; OMS 2.3.8 + mLAN Tools	Yamaha installation guide specifies OS 9.2 + OMS; its MY16-mLAN section excludes OS9. Requirements differ by mLAN generation; do not substitute another generation’s driver. Yamaha installation guide
