@DieHardThe only software I found was the Roland ASIO Driver on their website, which does not install a fully working system 
Please correct me if you simply installed the posted web driver:

Correct, I used the Roland official drivers for OS9.
I did look at Archive.org and compare the drivers from the Edirol site.
Edirol Archive Drivers From Feb/2004 Edirol Archive Driver From May/2005 
The URL was an empty link, but it was:
http://download.edirol.com/drivers/mac/FA-101_Mac_OS_9_Driver_E.sitAnd after looking at Archive.org more, it didn't seem like Edirol ever made anything beyond a v.1.0 for the OS9 driver, but did update to 1.06 for Windows XP.
I'm thinking of setting up another older box to try up the drivers to see if there is a firmware change or any other options.
When using the FA-101 I did change a few of the hardware settings to get it working consistently:
-

- Direct Monitor, Soft CTRL was pushed in and selected.
- The Sample Rate at 192, which was recognized by LIVE as 96k and I believe Cubase did as well.
- Mix was set to 100 percent output and Mono Monitor is off.
The audio is routed out from the headphones to a USB mixer for my Mac M1.
With the inputs, all of them work - but the inputs on the front 1/2 come out hotter and punchy with either Line-In or XLR inputs.
The Levels monitor worked, no issues.
Ableton Live respected the inputs and I was able to connect the firewire post startup, just to see if the FA-101 needed to be connected at boot.




Cubase worked, but was picky about having the inputs disabled when I was doing anything with the audio, after recording.
No issues with Cubase recognizing all the inputs with stereo or mono pairs.
I don't know Cubase very well, but will take some time to learn more about how it works with audio.
Next on the list is to install Traktor DJ and see how the iPad with the midi control on TouchOSC work.
Ableton Live worked well when having multiple audio inputs streaming into the FA-101 and using Live VST Effects on the real-time audio.
@teroyk
Where you get OMS driver for that? Or did it work with usb mididriver of Freemidi only?
No driver, just did the basic install from Cubase and Live and followed the instructions from the forum here.
What I believe is the cable is recognized as USB-1 by other devices.
I noticed that on the iPad with Cubase and how it saw the midi output option.
No lag, no jitter, worked great inside of Ableton Live and will be testing it out with Traktor DJ.
