About the Workshop Booklets
The EDIROL M-16DX 16-Channel Digital Mixer delivers the power of digital
mixing to musicians at an incredibly affordable price. This crystal-clear 24-bit
digital mixer supports sample rates up to 96 kHz, and it’s extremely flexible,
with a wide range of analog and digital inputs and outputs, and effects. The
M-16DX’s USB connectivity makes it an ideal partner for a computer-based
digital audio workstation, and features such its pro EQ and the innovative
Room Acoustic Control make it an excellent live mixer as well.
Each M-16DX Workshop Series booklet focuses on one M-16DX topic, and is
intended as a companion to the M-16DX Owner’s Manual.
The M-16DX Workshop booklets require M-16DX O.S. Version 1.22 or higher.
You can download the latest O.S. for free from www.RolandUS.com/EDIROL.
About This Booklet
The M-16DX makes an great companion to a digital audio workstation—or
“DAW”—on a personal computer. To learn the basics of using the M-16DX
with a DAW, see the Workshop booklet Using the M-16DX with a DAW. After
you’ve checked that out, come back here for specific instructions on using
the M-16DX with Apple’s GarageBand™.
We’ll assume you know how to operate GarageBand. To learn about using
GarageBand, consult the built-in documentation in its Help menu. We’ll also
assume the M-16DX is connected to your Mac, and that it’s powered-up.
Understanding the Symbols in This Booklet
Throughout this booklet, you’ll come across information that deserves
special attention—that’s the reason it’s labeled with one of the following
symbols.
A note is something that adds information about the topic at hand.
A tip offers suggestions for using the feature being discussed.
Warnings contain important information that can help you avoid
possible damage to your equipment, your data, or yourself.
Setting GarageBand Preferences
Since GarageBand records only at a sampling rate of 44.1 kHz, set the
M-16DX to 44.1 kHz as described in the Using the M-16DX with a DAW
Workshop booklet.
To configure GarageBand so it’s using the M-16DX for its inputs and
outputs:
From the GarageBand menu at the top of the
1
screen, select Preferences...
At the top of the Preferences window,
2
click Audio/MIDI to open the Audio/MIDI
preferences pane of the Preferences window.
Set both the Audio Output and Audio Input
3
parameters to EDIROL M-16DX 44.1 kHz.

Setting Up a Track for Recording
Selecting Audio to Record
Create a new real instrument track.1

a mono input channel to which a mic or
•
instrument is connected—select the desired
channel from Mono 1 to Mono 4.
a stereo input channel to which you’ve
•
connected a keyboard or some other stereo
device—select the desired channel from
Stereo 5/6 to Stereo 15/16.

All of the channels have “(EDIROL M-16DX 44.1KHZ)” at the end of
their name. We’ve left out this phrase here just to make things easier
to read.

Turning Off Software Monitoring
As we noted in the Using the M-16DX with a DAW Workshop booklet,
you do have the option of listening through GarageBand if you want to
hear its effects as you record. However, since you’ll encounter latency
doing this, we recommend listening directly through the M-16DX.
Set the Monitor popup below Input Source to1 Off.
Troubleshooting
If you experience problems recording or playing back audio, GarageBand’s
built-in Help provides steps you can take to solve your problem. Search in
Help for “optimize”—the page of steps is called “Optimizing GarageBand
Performance.” In addition to following these steps, raising the Audio Buffer
size in the M-16DX’s control panel may also help, though it may also increase
latency if you’re working with soft synths in GarageBand.
