Each one of the stereo trigger in­
puts can send individual notes
numbers over individual MIDI chan­
nels for the pad and the rim. This
offers total flexibility to control a
large number of differen t sounds at
the same time. For example, you
could have each pad's surface
and/or rim trigger control a differ­
ent sampler inside of Reason 4. If
you want to go full bore, you could

While MIDI-Channel and MIDI­

majority of e-drumming situations,

textural drumming situations with­
out a lot of extra work. The iO
doesn't Include bells and whistles
such as alternate notes, stacked
notes, gate time controls, or con tin­
uous controller information. De­
pend ing on your software, though,
you might be able to create some
work-arounds that wou ld allow you
to take advantage of those features
if you really need them .
Setting individual values is pretty
easy. You simply strike the pad or
rim that you want to program and
the iO "chases" to display that In ­
put for your programming pleasure.
Once you've selected the proper
pad, simply select the MIDI chan­
nel and the note number. One of
th e trickier aspects of the operating
system is saving your changes to a
kit. Since there is no dedicated
"save" bullon, you save your
changes by using the func tion but­
tons to return to the "kit' function .
By doing this, any changes you've
made to your programming are au­
tomatically saved. If you don't want
to save your changes, you press

good reason to RYFM (read your
freakin' manual), no matter how
simple the OS might seem at firs t
glance. Believe It or not. the man­
ual to the Trigger iO is rea lly prelly
good. I found that It was easy to
read and clear to understand. And,
the included troubleshooting guide
could be very helpful if you run into
any problems.
One other programming issue:
While the iO chases triggers for
programming, the screen doesn't
indicate which of the triggers is
currently being programmed. If you
should accidentally bump into a
trigger dUring the programming
process, It's possible that you'll
jump to programming a different
trigger without realizing it.
As you might expect , global set­
tings are those that affect the trig­
ger inputs for all 21 kits. What
many manufacturers call "sensitiv­
ity" Alesis calls "gain:' By changi ng
the gain setting, you're making ad­
justments to how hard you'll need
to strike in order to get a maxim um
MIDI volume reading of 127. Th e
values of gain range from 0-20,
with lower values requiring more
powerful strokes.
It's rare to see so many velocity
curves available on a unit in this
price range. In all, there are 15 dif­
lerent curves you can call up to
SUit your playing style or a particu­
lar function. Curves include linear,
constant, and offset, as well as
four each of exponential, logarith­
mic, and spline curves. The refer­
ence manual contains nice graphic
illustrations of how the various
curves work.
A pad's thresh old may need to
be adjusted il you're gelling false
triggering from external vibrations.
This value is the minimum signal re­
quired for a trigger to send data.
Values here range from 3-64.
Crosstalk occurs when the strike
from one trigger causes another
trigger to vibrate and send a signal.
Unfortunately, crosstalk is some­
what common on stereo pads with
triggers on the head and rim. Oc­
casionally, crosstalk can occur
when pads are mounted on racks
that transfer vibrations between
separate pads. To cancel crosstalk,
weaker signals that arrive at nearfy
the same time as stronger sig nals
will be ignored. Crosstalk values on
the iO range from 0-7. When thiS
crosstalk value is set to higher
numbers, stronger crosstalk veloci­
ties will be ignored.
The ret rigger value determines
how the iO will react to successive
trigg ers from the same input. While
adjusting the retrigger time is criti­
cal when triggering from acoustic
drums, it can also be important
when working with pads. The faster
you play, the lower you'll want to
set these values .
The trigger iO offers a large se­
lection of trigger types to work ef­
fectively with a variety of pads. Six
different types are offered:
piezo/piezo, switch/switch,
piezo/switch, switch/piezo, switch
(as with a sustain pedal), and hi-hat
pedal. The Alesis web site contains
a pdf file that lists the compatibility
of various manufacturers' pads with
the Trigger iO. You may want to re­
fer to thi s chart to be sure that your
pads will operate as desired with
the unit. Al so on the site is another
pdf with a good explanation of
dual-zone pads that use both piezo
and switch triggers.
As an added bonus, the iO comes
with a copy of Fxpansion's
BFDlite. This is a terrific program.
Instal l the software and you'll be
up and playing in ju st a couple of
minutes. While the lite version
doesn't contain as many instru­
ments as the full-blown version
(9GB worth on two DVDs), it's got
enough sounds to get you going
and enough features to tease you
in to buy ing the whole ench ilada.
The iO also includes a 9-volt
power adapter for when you want
to use the unit without hooking up
the USB cable.
Unique to the Trigger iO is the
ability to upgrade its internal soft­
ware. While there are no upgrades
currently on the Alesis site, should
one become available, you'll be
able to download it to your com­
puter and dump it into the 10.
No matter what the features are,
the most important things about a
trigger interface are how well it
tracks you r dynamic subtleties and
how fast and cleanly it tracks your
strokes. I tried the iO with a vari­
ety of Yamaha pads, Roland pads,
and Alternate Mode pedals. I ran
the iO into Reason, Live, and the
BFDlite software that comes
shipped with the unit. I used both
the internal sound engine in my
Mac B ook Pro 2.6gHz Intel Core 2
Duo, and the M-Audio Firewire
410 dig ital audio interface.
In my tests, the Trigger iO
worked pretty much as you would
expect. It was relatively easy to
tweak the iO so that the pads
smoothly responded to my playing
style (more adjustments were nec­
essary for my older Yamaha pads).
As mentioned earlier, there are sev­
eral trigger settings that work in a
somewhat inter-connected way. If
you're not happy with the triggering
response right off the bat, don't
give up. It might take a little time,
but it's time well spent and you
only need to do it once.
The unit triggered fas t, but
wasn't absolutely instant. I really
didn't notice much of a difference
when using the Mac's engine or
the Firewire 410. In fact, depend­
ing on your playing style and the
type of music you practice and
perform, you might not even notice
this. Keep in mind that each
millisecond of latency is about the
time it takes for sound to travel
12". Latency shouldn't bother you
until it gets above 1Oms. If you're
using the iO with a PC and aren't
happy with the latency, you can try
downloading an ASIO (Audio
Stream Input/Output) driver from
the Internet. You may fin d that this
helps make the unit laster. •
The bottom line is that for this
price, there's no other device on
the market that does what the
Trigger iO can do. It's small,
simple, and effective_For all but
the most sophisticated users,
