Understanding Modulation Sources and Destinations in Synthesis

If you're delving into the world of keyboard music and synthesis, comprehending modulation sources and destinations is crucial. UrbanPro.com's keyboard music tutors are here to guide you through this fundamental aspect of music synthesis.

Modulation Sources:

1. LFO (Low-Frequency Oscillator):

   • Description: An LFO generates low-frequency waveforms (often below the audible range) to modulate various parameters.
   • Use: LFOs are commonly used to add vibrato, tremolo, or other rhythmic effects to the sound.

2. Envelope Generators:

   • Description: Envelopes control the evolution of a sound's amplitude over time.
   • Use: They shape how a sound starts, sustains, and decays, affecting its tonal characteristics.

3. Aftertouch:

   • Description: Aftertouch is pressure applied to a key after it's initially struck.
   • Use: It can modulate various parameters in real-time, such as vibrato depth or filter cutoff.

4. Velocity:

   • Description: Velocity refers to how fast a key is struck.
   • Use: It's commonly used to modulate loudness, filter cutoff, or other sound properties, adding expressiveness to the playing.

5. Modulation Wheel:

   • Description: The modulation wheel on a keyboard allows real-time control of modulation depth.
   • Use: Musicians often assign it to modulate parameters like vibrato, filter, or pitch.

Modulation Destinations:

1. Pitch:

   • Description: Modulating pitch can introduce pitch bends, vibrato, or other pitch-based effects.
   • Use: It adds expressiveness and dynamic changes to the notes played.

2. Filter Cutoff:

   • Description: Modulating the filter cutoff changes the timbre of the sound.
   • Use: It's commonly used to shape the brightness or darkness of a sound.

3. Amplitude (Volume):

   • Description: Modulating amplitude affects the loudness or volume of the sound.
   • Use: It creates dynamic variations in volume, like fading in or out.

4. Pan (Stereo Position):

   • Description: Modulating pan adjusts the stereo position of a sound.
   • Use: It can move a sound from left to right or add a stereo-widening effect.

5. Effects Parameters:

   • Description: Various effects parameters, such as reverb or delay, can be modulated.
   • Use: Modulation can create evolving soundscapes by changing effects settings over time.
