Pad-X, Pad-Y These modulation sources allow you to define the axes of the Square, for use with the selected modulation target. The cursor can be moved to any position in the Square, either manually or controlled by the vector envelope. See “The Square” on page 291 and “The Vector Envelope” on page 293. Max If you select Max as a source, the value of this source will permanently be set to +1. This offers interesting options in conjunction with via, as the possible values available for via control the modulation intensity. Kybd Kybd (Keyboard) outputs the keyboard position (the MIDI note number). The center point is C3 (an output value of 0). Five octaves below and above, an output value of –1 or +1, respectively is sent. Note: This could be used to control the Cutoff frequencies of the filters in parallel with the keyboard position—as you played up and down the keyboard, the Cutoff frequencies would change. Modulate the Cut 1+2 target with the Keyboard source to do so. At a modulation intensity of 0.5, the Cutoff frequencies scale proportionally with the pitches played on the keyboard. Velo If you select Velo (Velocity), velocity sensitivity serves as modulation source. Bender The pitch bender serves as a bipolar modulation source, if Bender is selected. This is also true when the Oscillators’ Bend Range parameter is set to 0. ModWhl The modulation wheel serves as an unipolar modulation source, if ModWhl is selected. Note: For most standard applications, you’ll probably use the wheel as the via controller. Traditionally, it can be (and is) used for control over the intensity of periodic LFO modulations. Used here, it can be employed for direct, static modulations, such as controlling the Cutoff frequencies of the filters (Target = Cut 1+2). Note: The Least Significant Byte (LSB) controller for the modulation wheel is recognized correctly, as well. Touch Aftertouch serves as modulation source. The ES2 reacts to poly pressure (polyphonic aftertouch). It uses the sum of channel pressure and the note-specific poly pressure value. Note: If you set the target to Cut 1+2, the cutoff frequencies will rise and fall, dependent on how firmly you press a key on your touch-sensitive MIDI keyboard after the initial keystrike.
