 DM-24 version 2.0—Release notes—I/O setup changes
No assignment to a channel
When you are making assignments to the DM-24, as 
described in “Assigning inputs to channels” on 
page 40, a new “source” has been added to the list.This is a null assignment, indicated by four dashes on 
screen 
----; in other words, no input is assigned to the 
selected channel when this option is selected.
This null assignment applies to channel inputs, to 
return sources, and to return blocks.
Group switching
Also note that there is now an option that allows a 
whole group to be switched between input and return 
settings, rather than your having to make individual 
settings for each channel in the group, as described in 
“Assigning inputs to channels” on page 40.Move the cursor to the on-screen “patch cable” of the 
center box to the left of the channel list (as high-
lighted here), and use the dial and 
ENTER key to 
change between 
INPUT and RETURN, as for individual 
channels.
Mic/line routing to Aux 1-2
It is now possible to assign mic/line inputs to Aux 1 
and 2, which is a similar concept to the way in which 
aux 1 and 2 can be used for tape returns (1 through 
16) in a tracking environment.
Now, when mixing, you can have channels 1 through 
24 used as tape returns, 25 through 32 as effect 
returns, and the sixteen mic/line inputs assigned to 
aux 1 and 2. These two aux busses can then be stereo 
linked, and assigned using the 
ASSIGN BUSS page to 
the stereo buss outputs.When this is done, you now effectively have 16 extra 
channels with pan and level controls, making a total 
of 48 mixdown channels (as in the 
48ch MIXING snap-
shot 000). These “new” channels are perfect for use 
as MIDI instrument channels.

 DM-24 version 2.0—Release notes—I/O setup changes
If an optional IF-AN/DM analog card is fitted, (see 
“New output assignment options” on page 7), busses 
1 through 8 can be used like post-fader analog effect 
sends, with the analog returns fed through the mic/
line inputs and routed through aux 1 and 2 to the ste-
reo buss.
The assignment of a mic/line channel to the aux 1 
and 2 busses is made on the 
MODULE SETUP screen as 
well as the 
AUX SOURCE screens:
On the 
MODULE SETUP screen, the ADD. SOURCE 
(additional source) parameter for modules 1 through 
16 can be set to 
RETURN or M/L. This can be set indi-
vidually for each channel.
On the 
AUX SOURCE screens (aux 1 and 2 are linked 
on the screen here), the source for channels 1 through 
16 can be selected either from 
PRE/POST/RETURN or 
PRE/POST/M/L, depending on the ADD. SOURCE setting 
for the channel:At the bottom of this screen is a 
SETUP section which 
allows you to make a “master” assignment setting. 
Use POD 1 to set the parameter to
 M/L and POD 2 to 
set the scope of the assignment to 
ALL. When you 
highlight the 
SET button and press ENTER, channels 
1 through 16 will be set to 
M/L (17 through 32 remain 
unchanged).
Use the 
ASSIGN BUSS screen to highlight the AUX 1-
2 to stereo assignment section, and press the 
ST key 
(
CH ASSIGN section).
Link aux 1 and 2 using the 
LINK/GRP key to get to 
the 
ST LINK screen, move the cursor to aux 1, and 
press 
ENTER.
You can use the 
AUX 1-2 LEVEL and AUX 1-2 PAN/BAL 
screens to set the level and pan values for these M/L 
inputs, just as for any other channel. These level and 
pan settings affect the signals sent to the stereo mas-
ter buss.
Remember that the input level of these signals is 
determined by the analog 
TRIM controls.
Digital outputs and Aux sends
Previously, Aux sends had to be paired (1-2, etc.,) in 
order to output them from the digital outputs. 
						

							 TASCAM DM-24 2.0 release notes 13
 DM-24 version 2.0—Release notes—Surround mode
It is now possible to select individual (mono) Aux 
send busses for output in this way. In this case, the 
left channel of the digital output is used for the Aux 
send.
Assignable inserts
The assignable inserts can now be used with the L-R 
stereo buss.This allows any effect you are inserting 
to be “monitored” directly (this can be very useful 
when mixing to a digital recorder).It also allows you to send a compressed stereo signal 
to digital outputs 1 and 2.
Surround mode
LPF on the Boom channel
This allows you to send only those frequencies below 
those selected on the LPF to the boom (LFE) chan-
nel. The choices are 
80Hz, 120Hz or OFF.
Center channel percentage You can now set 
the amount of signal allowed into the center channel 
(set as a percentage). If this center channel is 
reserved for dialog, you may not want effects intrud-
ing into it, and you may want to reduce the level sent 
to this channel for these effect tracks (an on-screen 
switch is also provided).
The switch and percentage level are shown in the 
screen above.

 DM-24 version 2.0—Release notes—Surround mode
Circle and square patterns (using the dial)
Note that you can now use the dial to set the position 
of the pan cursor in the surround screen, allowing for 
very easy 360-degree panning.
The dial can be used to make diagonal moves, etc. 
(except when the cursor is highlighting the center 
channel percentage, as explained above)Select either a square or circle type pattern and a size. 
Now moving the dial will act as a surround pan con-
trol, moving the source around the pattern as selected 
in the 
SURROUND 2 screen.
Using the cursor keys
If you check the CURSOR MOVE box in the SURROUND 
2
 screen, you can use the cursor keys to move the pan 
cursor in the appropriate direction (holding down 
two keys together moves diagonally).
Jumping using the keypad
JUMP, as defined here, allows the 2ND F key to be 
used together with the number keys in the following 
way:
Note that these moves can be automated.

 DM-24 version 2.0—Release notes—Effects (TC Works reverb)
Effects (TC Works reverb)
A new setting has been added to the previous three 
settings (
4s, 16s and 64s) for the decay range for the 
TC Works reverb internal effector.This new setting is 
1s, changing the on-screen view-
ing of the decay time settings.
Also, the stereo imaging of the TC Works reverb has 
been greatly enhanced in 2.0.
Effects (tap delay)
The external switch (typically a footswitch) can now 
be used to set the timing of the delay by tapping in 
time with the desired delay interval. See “External switch (footswitch) functionality” on 
page 24 for details of how to set up the switch.
Library
New options are now available on all library man-
agement screens.
Deleting library entries
While before, it was only possible to recall entries, 
and to overwrite unwanted entries, the new 
DELETE 
button allows the data in the highlighted library entry 
to be deleted. A popup message appears when the 
DELETE button is pressed, asking for confirmation of 
the delete action (read-only data cannot be deleted, of 
course).
Library safe
In addition to the existing parameters that may be 
saved when a snapshot is changed, the library snap-
shot screen now includes options to preserve both 
effect settings and effect patching.
Checking the 
EFFECT Settings box means that the val-
ues chosen for the effects will remain when the new 
snapshot is loaded.Checking the 
EFFECT Patch box means that the effect 
patches and routing to and from the internal effects 
are preserved when the new snapshot is loaded.
Undo/redo In addition, there is now an UNDO/
REDO
 button, allowing the last library recall operation 
to be undone or redone.

 DM-24 version 2.0—Release notes—External machine control
Snapshot recall
When a snapshot is recalled, MIDI Control Change 
messages are output, which correspond to the new 
settings of the following:
•Faders
• Mute status
• Pan controlsAdditionally, when a snapshot is recalled using 
MIDI, that snapshot is now shown as the current 
snapshot in all screens.
External machine control
Play (MMC) When operating an external device 
controlled by an open MMC loop, the command sent 
when the 
PLAY key is pressed may now be selected 
between Deferred Play and True Play.
As a result, it is now possible to use the 
PLAY key to 
control a number of DAW applications and HDR 
machines using an open MMC connection.
Track arming On the MIDI/MC SETUP page, there is 
a new parameter at the top right of the 
MACHINE 
CONTROL
 section (RecFn).
Set this to either 
TRUE(40h) or MASKED(41h). Previ-
ously, only the 
TRUE(40h) command was used, but 
units such as the Mackie HDR-24/96 and MDR-24/
96 require the 
MASKED(41h) setting. The DM-24 is 
now fully compatible with the Mackie recorder 
family.
Transport Lock Pressing the 2ND F. and STOP 
keys together locks the transport keys. This is useful 
to stop accidental playback or recording when you 
are leaning over the DM-24 adjusting parameters.
Press this key combination again to unlock the trans-
port keys. The popup changes
Internal MIDI Time Code generator The 
DM-24 now has its own generator, which can be used 
with DAWs, etc. which do not respond to MMC 
commands. By slaving them to MTC from the DM-
24, you can use the transport keys of the DM-24 to 
control these DAWs. 
						

							 TASCAM DM-24 2.0 release notes 17
 DM-24 version 2.0—Release notes—GPI functionality
To use the internal MTC generator, the SYNC SOURCE 
must be set to 
INT (internal), and the appropriate 
frame rate and internal generator start time selected 
in the 
OPTION SYNC/TC screen. See pages 23 and 24 of 
the main manual for full details.
GPI functionality
This release of the software added GPI functionality 
to the DM-24. Use GPI for tasks where items (video 
switchers, etc.) must be switched on or off, etc. as 
simple switching is available using this facility. The 
GPI outputs can be switched either using keys and 
faders on the DM-24, or they can be time events, trig-
gered when the timecode source reaches a preset 
point.
The DM-24 is fitted with a 9-pin D-sub connector on 
the rear panel, marked 
GPI. Pin 5 of this connector is 
used as a frame ground, and the remaining eight pins 
are then used as GPI ports.The ports provide switching (either a high-to-low or 
a low-to-high transition, or a momentary high or 
momentary low pulse).
The low level is 0 V, and the high voltage level is 
+5 V.
The typical load presented to these switches is 
12 mA, and the maximum load permissible is 25 mA.
Switching is virtually instantaneous (3 ns) and the 
width of the momentary pulses is 150 ms.
Using GPI Enter the GPI screen from the UTILITY 
screen, and use soft key 3 to move to the 
GPI tab.
Set up the 
ITEMs of the eight available ports from the 
following list:
•
TIME EVENT—this is a special item which disables 
this port for any manual events. If this is set, the 
TYPE is set to --- and cannot be changed here (it is 
set in the time event list). Also note that the enable/
disable button is also set to a the 
OFF setting, which 
cannot be changed, showing that the port is not 
available from the manual events.
•

•PLAY (pressing the transport PLAY key will trigger 
the event)
•
STOP (pressing the transport STOP key will trigger 
the event)
•
REC (pressing the transport RECORD key will trig-
ger the event)
•
FFWD (pressing the transport fast-forward key will 
trigger the event)
•
REW (pressing the transport rewind key will trigger 
the event)
•
INPUT ALL (pressing the DM-24’s ALL INPUT key 
will trigger the event).
The events triggered by these key presses can be any 
of the following:
Select the type depending on the unit (active high or 
active low). Press 
ENTER to confirm both the ITEM 
and the 
TYPE settings.
NOTE
For all keys triggering GPI events, the event is triggered 
when the key is active (the indicator lights), except in 
the case of 
MUTE keys which are being used to un-
mute a channel. In this last case, it is the key 
release 
that triggers the GPI event.
Faders The FADER types (the 32 channel faders, the 
aux and buss faders, and the master fader may also be 
used to trigger events) are slightly more complex. 
The illustration below shows the fader options (when 
the fader is pulled up from the minimum position, 
and then when it is pulled down to the minimum 
position):
Fader movement in either direction can also be used 
to trigger pulse events (as shown in the illustration 
below):
Time events When a port type has been set as a 
TIME EVENT on the SETUP half of the screen, it can be 
added to an event list as shown on the right of the 
screen. 
GPI time events can be entered on the fly for future 
replay by pressing the 
CAPTURE TC on-screen button 
when timecode is running. Alternatively, the dial can 
be used for setting and editing time values.

A port (defined in the SETUP part of the screen has to 
be selected for each event). Use the dial and 
ENTER 
key for this. Ports which have not been selected as 
time event ports produce a warning popup message.
Choose a type, as for the key manual events (either a 
transition or a pulse). 
NOTE
Note that the same port can output different types of 
event at different times. You should be careful when setting up a sequence of events from the same port to 
make sure that there is no conflict or contradiction. 
The event types can be changed even when timecode 
is running.
The events can be sorted by time (
SORT TIME) or by 
port (
SORT PORT) for easy checking.
Individual events in the list can be deleted by high-
lighting them and using the on-screen 
DELETE button.
MIDI fader layer
A new MIDI mixer layer has been added.
Previously, the audio faders, mutes and pan controls 
could be assigned to any MIDI channel and control-
ler number. While this capability has been retained, 
another MIDI layer with the same attributes that does 
not affect the audio faders has been added.
This new MIDI mixer layer is set from the external 
control screen. When this is active, the mute keys, 
faders, and the soft panpots send out MIDI Control 
messages.
Use the MIDI 
CTRL.CHANGE screens to determine 
what messages are sent by each DM-24 control. This 
screen shows the faders and pan settings:And this one shows the mute settings:, 
The default setting is for DM-24 channels 1 through 
16 to transmit on the corresponding MIDI channels, 
with the fader being controller 7, the pan controls 
(shown below) being controller 10 and the mute 
being controller 11.
NOTE
The following MIDI controllers may not be assigned to 
DM-24 controls: 0, 6, 32, 38, and 96 through 127. Warn-
ing messages are shown if duplicate assignments are 
attempted. 
						

							20 TASCAM DM-24 2.0 release notes
 DM-24 version 2.0—Release notes—GPI functionality
On the MIDI/MC SETUP page, the filtering of MIDI 
Control Change messages can now be carried out 
independently for external control (
EXT.CTRL) and 
Mix parameters (
Mix Parm). These can be set inde-
pendently for In and Out for both types of Control 
Change message.
HUI emulation
The DM-24 is now able to emulate the Mackie 
HUI™ device, and can therefore act as a controller 
(pans, sends, faders and mutes) for various DAW 
applications (e.g. ProTools, Digital Performer and 
Nuendo) via MIDI.
NOTE
This is not a 100% emulation of every one of the 
Mackie HUI functions, and there is no guarantee, 
despite our best efforts, that an external unit that is 
controlled by a Mackie HUI will behave identically in 
every circumstance as the same unit controlled by the 
DM-24’s HUI emulation.
The HUI “device” is a closed loop MIDI device, and 
is selected from the machine control list (if the closed 
loop is not detected, the display shows a cross for the 
device type, rather than the double-headed arrow 
usually used to denote a closed loop device. There is 
one parameter which may be set here—the MIDI 
channel (from 
1 through 16).
The setup enables MIDI to be received by the HUI 
emulation as well as setting the ID of the device. 
HUI transport emulation, etc. can be enabled or dis-
abled in this screen and the external control screen 
(described below) enables other functions.
As with other machine control devices, the 
SCREEN 
button jumps to the special screen from which the 
HUI is controlled:
