Example of Synthesizer's Parameter Use

 

  • Legato Mode: When you play a note before releasing the previous note, the ADSR does not activate.
  • Portamento: When you play notes legato, the synthesizer glides through all frequencies before settling on the next note. Portamento was used extensively in West Coast Rap. Listen to "Ain't nothin' but a G Thang".
  • Polyphony: How many notes you can play at the same time. My song should be set to 1 note polyphony. We would describe this sound as monophonic. Portamento only really works well on monophonic sounds.
  • Waveforms: Square for my song. Emphasizes odd harmonics. Creates a hollow sound.
  • Octave: What octave the oscillators sound in. My song is set to 4.
  • Cent: "Cent detune" - There are 100 cents per half-step. This is used to detune one oscillator from the other. Having two oscillators playing slightly out of tune makes a natural chorus effect.
  • LFO: Low Frequency Oscillator.
  • Filter Frequency: This is an adjustable low-pass filter on my song. I am cutting the highest part of the spectrum slightly to smooth out the edge of the square wave.
  • Resonance: This sends the output of the filter back into the filter. The result is a steep peaking EQ that makes the sound "wet" like it were bubbling through water. Resonance makes the patch "funky". I want my song to be only slightly funky.
  • Filter Envelope: Opens and closes the filter automatically every time a note is retriggered.
  • Amp Envelope: Amplitude Envelope. Otherwise known as acoustic envelope or ADSR. Note that my song has a moderately slow release so the sound hangs on for a moment after I release the key.
  • Velocity: I set all knobs to the "12:00" detent position. This means that my synth will not respond to velocity information. Press the key hard or soft, it will sound the same.
