Modulators
Tip:
When editing any parameter that has a center value (+00), there is an easy way to reach that
value. While holding down the Down Arrow button, press the Up Arrow button, then quickly
release both buttons.
Modulation Sources
The 15 Modulation Sources available on the ASR-10 are as follows:
• LFO - Low Frequency Oscillator
• KBD - Keyboard Tracking
• NOISE - Noise Generator
• PITCH - Pitch Bend Wheel
• ENV 1 - Envelope 1
• WHEEL - Modulation Wheel
• ENV 2 - Envelope 2
• PEDAL - Voltage Control Foot Pedal
• PR+VL - Pr Velocity
• XCTRL - External Controller (MIDI)
• VEL 1 - Convex Velocity Curve
• PRESS - Pressure (After-touch)
• VEL - Linear Velocity Curve
• WL+PR - Mod Wheel + Pressure
• VEL 2 - Concave Velocity Curve
• OFF - No Mod Source selected
• LFO — Low Frequency Oscillator
The Low Frequency Oscillator generates only very low frequency waves below the audio
spectrum, which can produce vibrato, tremolo, and many other effects, depending on the LFO
wave selected, and where it is applied as a modulator. There are seven possible waveshapes
for the LFO.
• NOISE — Noise Generator
The Noise Generator produces a randomly changing level. It is useful for modulating, among
other things, the pitch of a WaveSample (Edit/Pitch page). Applied to pitch with large
modulation amounts it tends to create strange “computer sound” effects. Small modulation
amounts (2 to +4) can create a subtle random movement in the sound, which can
impart a more natural quality.
When STEREO LAYER LINK= ON, the NOISE modulation source in the right layer will be
synchronized with the NOISE modulation source in WaveSamples assigned to the same or
overlapping key zones in the left layer.
• ENV 1, ENV 2
The ASR-10 has three complex Envelopes. Envelopes are used to create changes over time in
brightness, pitch, volume, etc.
• ENV 1 is permanently routed to the pitch of the WaveSample, though it can be assigned as
modulator elsewhere if you wish.
• ENV 2 is permanently routed to the filter cutoff frequency. It also can be assigned as a
modulator elsewhere.
• ENV 3 is a special case. ENV 3 always controls the volume of the WaveSample, and cannot be
selected as a modulator.
• PR+VL — Keyboard Pr Velocity
This is one of two “combination” modulators. When this modulator is selected, both pressure
and velocity will affect the modulation destination. After the note-on velocity has modulated
the note played, pressing into the keyboard will change the modulator output set by velocity.
After pressure has been exerted on the keyboard, pressure becomes the modulator until the
note is released.
