Channel, and the sound source receives on one. Check to see what MIDI channel you are transmitting
on in the trapKAT. Then check your sound source to make sure that it is receiving on the same channel.
To see what MIDI channel you are transmitting on your trapKAT, step on the KIT EDIT Footswitch,
and while held down, tap on pad 1. The MIDI channel will be displayed. You can change the channel
by hitting pad one repeatedly. If you want to have different MIDI channels on different pads, tap on pad
11. The screen will ask what pad you want to see the MIDI Channel.
THERE IS A BIG DELAY WHEN I USE MY COMPUTER
When any MIDI controller is plugged into a computer for the purpose of sound generation, latency
becomes an issue. What should be noted is that the delay heard is not coming from the trapKAT. The
trapKAT sends out data in about 1mS. (that's 1000
th
of second). Sound generation from a computer can
be 10 times that, and that can be very noticeable.
If you decide to use a computer for sound generation, consider getting the fastest computer you can
afford with plenty of RAM. Today computers are sold with SSDs (solid state drives). These are much
faster than traditional drives and they are truly road worthy.
The real culprit for latency is the sound card in the computer. It simply isn't fast enough for use as a
musical instrument. Of course it's fine for playing back music, but not for real time generation of
sound. To that end, manufacturer's have created external Audio/MIDI devices that use special drivers
(ASIO for example) that are designed for using your computer as a sound source. Using an audio/midi
interface is even more critical for drummers because we hear latency much better than other musicians.
Even when you get this device (there are many to choose from.. just type in AUDIO MIDI INTERACE
in GOOGLE) , there are settings that are crucial for dealing with latency issues. In the preference
screens on these devices you can control the Sample Rate and Buffer Rate. Raising the Sample Rate
and Lowering the Buffer Rate assures the lowest latency, but it puts the most demand on your
computer. Usually the preference screen also displays the latency in mS. You will need to find the
balance between CPU usage and latency.
WHAT'S A GROOVE, CAN I MAKE MY OWN
There are Grooves built into the trapKAT, but it is a feature that comes from the past. Remember that
the trapKAT was introduced back in 1995. It's intention was to have a groove ready to play when the
trapKAT was sitting in the stores. These grooves were built to work in the GENERAL MIDI format. If
you are plugged into a GM compatible sound source, the grooves will work fine, but they do not sound
correct when you are using the Kurzweil sound card. Perhaps with enough requests for an upgrade, we
will create new grooves to work especially for the Kurzweil. Unfortunately, the grooves are preset and
new grooves can not be created by the user. In the GLOBAL EDIT section, the operation of the grooves
will be described.
GET RID OF THE BEEPER SOUND
Turning the Beeper On or Off is done by stepping on the Global Edit Footswitch, and while held down,
tap on pad #19. The screen will display its current setting. To change it, tap on pad #20
