Modulation Matrix Parameters

Modulation Sources and Modulation Modifiers

The following options are available as modulation sources and as modulation modifiers.

LFO A/B: The LFOs A and B produce cyclic modulation signals.
Amp Envelope: The amplifier envelope. The shape of the envelope determines the modulation signal.
Filter Envelope: The filter envelope. The shape of the envelope determines the modulation signal.
Env 3: A freely assignable envelope. It is suitable for pan or pitch modulation, for example.
Key Follow: This produces an exponential modulation signal derived from the MIDI note number. Exponential means this source works with destinations such as Pitch or Cutoff.
Note-on Velocity: Note-on velocity can be used as modulation signal.
Note-on Vel Squared: The squared version of Note-on Velocity. The harder you press the key, the higher the modulation values.
Pitchbend: The position of the pitchbend wheel can be used as modulation signal.
Modulation Wheel: The position of the modulation wheel can be used as modulation signal.
Aftertouch: Aftertouch can be used as modulation signal. Some MIDI keyboards cannot send aftertouch messages. However, most sequencer software is able to produce such messages.
Arp Controller 1–3: The 3 controllers available on this submenu correspond to the three controller lanes on the Arp page.
Bus 1–8: Modulations that are sent to one of the eight busses can be reused as sources. This way, you can combine several modulations to produce more complex signals.
Quick Control 1–8: The quick controls can be used as modulation signal.

Unipolar vs. Bipolar Sources

The polarity of a modulation source specifies the value range that it produces. Unipolar sources modulate between 0 and +1. Bipolar sources modulate between -1 and +1.

To change the polarity of a modulation source or modifier from unipolar to bipolar, activate its Bipolar button.

Modulation Destinations

Pitch

Modulates the pitch. For example, assign one of the LFOs to create a vibrato effect. If Pitch is selected, the modulation depth is set in semitones.

Cutoff

Modulates the filter cutoff.

Resonance

Modulates the filter resonance. Resonance changes the character of the filter.

For example, to accent the filter the harder you hit a key, assign Velocity to Resonance.

Distortion

Modulates the filter distortion.

Level

This modulation adds to the level setting. It can be used to create level offsets using the mod wheel, for example.

Volume

Modulates the gain. The volume modulation multiplies with the level.

Pan

Modulates the position of the sound in the panorama.

Amp Env Attack

Modulates the attack time of the amplitude envelope. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.

Amp Env Decay

Modulates the decay time of the amplitude envelope. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.

Amp Env Sustain

Modulates the sustain level of the amplitude envelope. This modulation destination cannot be modulated continuously. The level is updated only when the segment starts.

Amp Env Release

Modulates the release time of the amplitude envelope. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.

Filter Env Attack

Modulates the attack time of the filter envelope. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.

Filter Env Decay

Modulates the decay time of the filter envelope. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.

Filter Env Sustain

Modulates the sustain level of the filter envelope. This modulation destination cannot be modulated continuously. The level is updated only when the segment starts.

Filter Env Release

Modulates the release time of the filter envelope. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.

Env 3 Start Level

Modulates the start level of the user-definable envelope 3, that is, the level of the first envelope node. This modulation destination cannot be modulated continuously. The level is updated only when the segment starts.

Env 3 Attack

Modulates the attack time of the user-definable envelope 3. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.

Env 3 Attack Level

Modulates the attack level of the user-definable envelope 3, that is, the level of the second envelope node. This modulation destination cannot be modulated continuously. The level is updated only when the segment starts.

Env 3 Decay: Modulates the decay time of the user-definable envelope 3. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.
Env 3 Sustain: Modulates the sustain level of the user-definable envelope 3. This modulation destination cannot be modulated continuously. The level is updated only when the segment starts.
Env 3 Release: Modulates the release time of the user-definable envelope 3. This modulation destination cannot be modulated continuously. The time is updated only when the segment starts.
Env 3 Release Level: Modulates the release level of the user-definable envelope 3, that is, the last user envelope node. This modulation destination cannot be modulated continuously. The level is updated only when the segment starts.
Bus 1-8: You can send any modulation to one of the 8 busses, for example, to produce more complex modulation signals. Select the bus that you want to send the signals to as a destination. To use the modulation that was sent to a bus, assign the corresponding bus as a modulation source.
