ULN-2 Quick Start Guide
83
DSP environment available to the public. Creative users have built custom stereo to 5.1 spatial up-
mix processors, analog tape noise reduction, and multi-layered FOH speaker array time delay and
acoustic correction tools, to name just a very few. Graphs can be very simple - just build a quick little
tool to do some one-off task not gracefully handled by a packaged plug-in… Graphs are especially
spectacular for creating new types of parallel processors because no matter how complex the pro-
cessing it is all fully internally latency-compensated.
• I/O: A basic signal path insert-within-an-insert, if you will. From within any strip, send to any hardware
output or the Host computer and return from any hardware input or the Host. I/O is very useful for an
extra Direct Out, as a sidechain source, or for mults to secondary systems (external backup recorder,
video truck feed...), etc.
Note: Since an I/O send/return insert sends audio to external systems outside the mixer DSP and
back, I/O loops can not be automatically latency-compensated.
As a reminder, all of the mixing, gain control and processing which is shown and accessed through the
MIOConsole3d is operating solely in the box(es) and not on the computer, even though the user interface
for the 3d Mixer is controlled from the computer display. This is an important distinction to keep in mind
so you can properly manage your sessions and take best advantage of the strengths of both the DAW
and the 3d hardware.
Now let's walk through adding the ULN-2's eight ADAT channels into the MIOConsole3d mixer and your
DAW. This procedure works with any kind of input from any box in the domain.
First hit command-shift-A to create a new input strip. In the routing window that pops up, select "Digital"
from the filter list on the left (to show only the digital inputs), select "ADAT 1", type "8" in the Cascade
box at the bottom of the routing window and hit Apply (or Return or Enter).
With these few clicks, you have instructed the Mixer to create eight new input strips assigned starting at
ADAT Input 1 (i.e.: ADAT inputs 1-8), and your mixer should now look like the one in the example above.
The Mixer defaults to automatically assign routes to the Host computer for each strip, starting with the
next available To Host channel... so, since the two analog input strips are already using To Host routes 1
and 2, these new strips will use To Host channels 3-10.
Now, go back to your DAW, create eight new input strips in your DAW mixer and assign them to input 3-10.
You have built a virtual patchbay routing audio between your DAW and the ULN-2. You can route pre- and
post-insert Direct Outs, Aux buses, Group buses and the Main bus back to the Host DAW in the same way.
To disable any route, just open the routing window and select "None" at the very top of the strip inputs list,
or mouse over the strip inputs button and click the "X" to delete that route and free it up for another task.
Mixer Strip Color Bars
Clicking on the Color Bar at the top or bottom brings up a macOS color selector, from which you may
choose a color for that Mixer strip. In the Appearance pane of the MIOConsole3d Preferences you may
select whether to color the entire mixer strip or just the top and bottom color bars.

The Bottom and Top Color Bars mirror each other, so what applies to one applies to the other. You may
show or hide the opt or bottom color bars independently with “Configure Mixer Strip Controls...” .
