The Banks

McDSP associates The Banks with:

FilterBank 1.1.1
CompressorBank 1.1.1

Both:

Mac OS 8.1
NuBus — Limited Support

Key installer package for a period NuBus McDSP system.


Analog Channel — NuBus

McDSP compatibility archive:

Analog Channel 1.0 — NuBus*
Analog Channel 1.0.1 — NuBus*

Mac OS 9.0.4 generation.

AC1 — analog channel / preamp / saturation
AC2 — tape modelling

Contemporary AudioTechnology review:

Component	NuBus	Capacity
AC1	YES	2 mono instances
AC2	NO	—

MIX DSP — 24 mono / 16 stereo
PCI III — 9 instances
NuBus — 2 mono AC1 instances

Analog Channel NuBus = AC1 only.


NEW — Analog Channel 2.2 Installer Evidence

Original:

AC_Installer_2_2_1_OS9.hqx

Filename version: 2.2.1
Embedded ReadMe: 2.2
ReadMe date: 10/15/2003

McDSP's embedded ReadMe states:

Nubus support has been removed as of version 1.1.

Therefore:

1.0.x — NuBus generation
1.1+ — no NuBus support

This independently confirms the transition shown in McDSP's compatibility database.

The same ReadMe lists:

d24
MIX
MIX-plus
HD
HD Accel
Digi 001
Toolbox
PowerMix

OS 9
OS X

Minimum Pro Tools 3.2
Pro Tools 4.0+ for control automation


2003 Mac OS 9 Installer Forensics

Six original McDSP HQX installers examined:

Product	Installer	ReadMe	Date
Analog Channel	2.2.1	2.2	10/15/2003
CompressorBank	3.2.1	3.2	10/15/2003
Chrome Tone	1.0.1	1.0	10/15/2003
FilterBank	3.2.1	3.2	10/15/2003
MC2000	2.2.1	2.2	10/15/2003
Synthesizer One	3.0	3.0	10/15/2003

Common installer facts:

Classic Mac APPL
Creator: VIS3
Installer VISE 8.2.1
PowerPC PEF present
McDSP Authorizer resources present
iLok / iLok.com resources present
DAE / Plug-Ins / TDM installation resources present

Important: current forensic pass covers the HQX + Installer VISE resource/documentation layer. The compressed VISE payload has not yet been unpacked into the final installed DAE plug-in binaries.

These 2003 installers document the later Mac OS 9 generation; they do not establish NuBus compatibility by themselves.


MC2000 — NO NuBus

McDSP documentation discusses:

ProTools|24, Nubus, and MIX DSP hardware

MC2000 exceeds the processing capability of the classic Pro Tools|24 / NuBus DSP hardware.

MC2000 — NO NuBus


Chrome Tone — NO NuBus

McDSP documentation states its processing requirements exceed the capability of classic Pro Tools|24 / NuBus DSP hardware.

Chrome Tone — NO NuBus


Other McDSP Products

No documented NuBus path found for:

Channel G
Chrome Tone
MC2000
Revolver
Synthesizer One

Documented NuBus McDSP family:

FilterBank
CompressorBank
Analog Channel AC1


Digidesign NuBus Host Limit

1994-11-28 — Pro Tools 3.0 — Pro Tools III NuBus

1997-03-21 — Pro Tools 4.0 — NuBus + PCI; AudioSuite

1998-06-23 — Pro Tools 4.2

1998-09-25 — Pro Tools 4.3 — MIX introduced; NuBus dropped

Digidesign Technical Support:

Pro Tools 4.2 is the last Pro Tools version supporting NuBus hardware on a PowerPC Macintosh.


DAE Limit

Pro Tools 4.2 = DAE 3.3

Sweetwater's preserved DAE compatibility information:

DAE 3.3 is the highest DAE version supporting NuBus machines.

Last officially supported Digidesign NuBus stack:

Pro Tools 4.2
DAE 3.3


Cleanest Documented NuBus Setup

PowerPC NuBus Macintosh
Pro Tools III NuBus
Pro Tools 4.2
DAE 3.3
Mac OS 8.1

FilterBank 1.0.4 or 1.1.1
CompressorBank 1.1.1

McDSP explicitly lists these releases for Mac OS 8.1 with NuBus limited support.


Mac OS 9 / Late NuBus McDSP

McDSP's matrix lists:

FilterBank 2.0 — NuBus* — Mac OS 9.0.4
CompressorBank 2.0 — NuBus* — Mac OS 9.0.4
Analog Channel 1.0 / 1.0.1 — NuBus* — Mac OS 9.0.4

Sweetwater still documented FilterBank / CompressorBank NuBus support in 2000.

Confirmed:

McDSP retained NuBus support through FilterBank 2.0.
McDSP retained NuBus support through CompressorBank 2.0.
Analog Channel 1.0.x AC1 supports NuBus.
Analog Channel 1.1 removed NuBus support.
Digidesign's official NuBus host line ends at PT 4.2 / DAE 3.3.

Not proven:

An officially qualified combination of:

Pro Tools 4.2
DAE 3.3
Mac OS 9.0.4
FilterBank 2.0 / CompressorBank 2.0 / Analog Channel 1.0.x

McDSP's matrix documents these compatibility dimensions; it does not prove every possible combination was officially qualified together.
