If you want to change the MIDI Channel on just one pad, use pad #11, Pad MIDI Channel. When you
tap on pad# 11, it will ask you to select the pad that you want to change the MIDI Channel.
There are 16 MIDI channels available in MIDI. Any pad can be assigned to it's own MIDI channel. If
you have a multi-timbrel sound module, very creative kits can be created! A different program sound
can be assigned to any MIDI channel, allowing the trapKAT to control many sounds at once.
KIT VELOCITY (Minimum, Maximum, Velocity Curves)
Pad #2,12, 3,13, 4 and 14
There are three settings that affect the response of each pad. They are called Minimum and Maximum
Velocity, and Velocity Curve. The Min and Max Velocity affect the range of how loud or soft an
individual sound can be. The Velocity Curve affects the feel or how fast the sound gets louder as you
smoothly play harder and harder.
The range for velocity is 00-127. If you set the Minimum to 00 and the Maximum to 127, you are
programing the pad to play the widest dynamic range possible. Counter to what you may first think,
this is not always the best choice. For example, most people find that the bass drum needs a narrower
range, say 32-127. If the softest hits are not heard, then you will need to raise the Minimum Velocity
Setting. If you want the same crack of a snare drum, you might want to raise the Minimum Velocity
even higher. If you hear a sound that is not balanced, i.e. too loud, you might want to lower the
Maximum Velocity.
After the range is set, the next factor to consider is the Velocity Curve. The curve tells the trapKAT how
fast to change from soft to loud. Usually folks like a linear or smooth response, and use the default
Curve #1. There are exponential and logarithmic curves that stay soft longer as you play harder or the
other way around.
It is possible to set one Minimum, Maximum and Curve Setting for the entire kit. Use pad 2 for the Kit
Minimum Velocity, pad 3 for the Kit Maximum Velocity. The range possible is 00-127. Use pad 4 to
Select a Kit Curve. There are 8 “normal” curves to choose from and then there are “special curves”
discussed below.
The normal curves are...
Velocity Curve 1 Linear-smooth from soft to loud
Velocity Curve 2 Stays soft longer than curve 1
Velocity Curve 3 Stays soft even longer than curve 2
Velocity Curve 4 Slow linear curve with an accent on the top end
Velocity Curve 5 High minimum, stays even then accent on top
Velocity Curve 6 moves from soft to loud much quicker than curve 1
Velocity Curve 7 another variation on the Linear Curve
Velocity Curve 8 and another variation of the Liner Curve
As you can see, these curves are very subjective. They will sound different depending on the sound, the
velocity ranges set and the curve factor built into the sound module. It is for this reason we recommend
that you stay with Curve 1 unless you want “more” or something different. Experiment.
