Using Pressure (Aftertouch) As An Arpeggiator Controller; Using The Arpeggiator With A Sequencer Or External Controller - Kurzweil PC2KBD Musician's Manual

4. Press > to select the Zone Enable parameter. This enables you to arpeggiate one or more
setup zones, and play others normally. Several of the preset setups do this.

Using Pressure (Aftertouch) as an Arpeggiator Controller

In this example, weÕll use pressure to control the volume of arpeggiated notes.
First, make sure that keyboard aftertouch is sending the Pressure Controller message. Hold the
Controllers button, strike any key and press down on it. The display will change to show
Zone:1 Mpressure, Ctrl Num: Pressure. If it doesnÕt, press 132, then Enter to assign the
MPressure controller (your keyboard aftertouch) to send Pressure.
Aftertouch is somewhat similar to the Pitch Wheel, in that it functions like a spring; it returns to
0 as you let go of the key. Like the sliders, wheels, and continuous control pedals, you can assign
aftertouch to send any MIDI controller number. However typically, aftertouch is assigned to
Pressure, which is a separate MIDI message.
One Þnal thing to understand: There are actually two different types of aftertouch: Mono
Pressure and Poly Pressure. Mono Pressure has a single strip running across the keyboard, so
pressing down on any note will generate controller info that will affect all the notes played on
that MIDI channel. Poly Pressure has a separate sensor for each key so pressing down on a key
only affects that key. The PC2 uses Mono Pressure.
Press the Arpeggiator button, then press > until you see the Vel Mode parameter. Set its value to
Pressure. Now when you hold down keys, the volume of each arpeggiated note is controlled by
how hard you press on the keys.

Using the Arpeggiator with a Sequencer or External Controller

If you are sequencing and create a setup that uses the arpeggiator, the PC2 will send the actual
notes that were generated by the arpeggiator to the sequencer. When you play back the
sequence, it simply sends back those notes and does not actually play the arpeggiator itself.
But if, for some reason, you need to have the sequencer or other external controller send notes to
the arpeggiator itself, you must use the Remap function. To do this, press the Global button,
then press > until you see the MIDI In parameter. If you set this to Remap, then all incoming
MIDI note messages will be treated as if you played those notes on the keyboard of the PC2
itself.
The MIDI channel info on the incoming data is ignored; The PC2 simply takes the note numbers
and sends them to each zone based on the note range settings for that zone. ItÕs the same as
playing that note on the keyboard itself. So you probably wouldnÕt want to send more than one
channel of MIDI information from an external controller, since the note messages will get mixed
together.
Another thing to be aware of is that all controller messages will be sent to all zones. So, for
example, if you have a setup with zones assigned to Channels 1, 2, 3, & 4, then a sustain message
coming in would be sent to all four MIDI channels.
