Specifications

For maximum track count, the G4 requires the use of a qualified SCSI HBA
card. Optional SCSI HBA cards bundled (by Apple) with Power Macintosh
computers are not compatible with this configuration due to the lack of NV
RAM to store Pro Tools desired SCSI transfer rate. The following SCSI HBA
cards are qualified with the G4s listed at the top of this page:
ATTO ExpressPCI SCSI HBA Card EPCI-DC (ExpressPCI Dual Channel
Ultra/WIDE HBA) only, with the following requirements:
● ATTO ExpressPCI Firmware v1.4.4 f1
● ExpressPro-Tools v2.3.2 or higher with Synch Transfer Rate set to
20 (10) and PCI Burst Rate set to 32 bytes
● ATTO ExpressPCI Firmware v1.4.4 f1 is available at:

MIDI: Both USB and serial MIDI interfaces work effectively with Pro Tools.
Digidesign recommends using a serial MIDI interface, as they offer the
tightest possible MIDI timing. Serial MIDI interfaces require either a Mac
serial port or a qualified modem-to-serial port adapter. Digidesign
currently supports the GeeThree Stealth Port and Griffin gPort installed in
the modem port (thereby not using a PCI slot).
When using the GeeThree products with OS 9.0.4 the latest version of the
Stealth Port extension (v1.0.3) is required. It is available here:

DSP Farm and SampleCell II Support: The PCI Matchmaker chip on a
DSP Farm must be rev QC or QE (check the end of the line directly below
“PCI Matchmaker” on the chip) to be compatible. Cards with rev Q chips
can be upgraded.
