Amplitude modulation

Your Woovebox comes with one dedicated ADSR amplitude envelope generator and one dedicated amplitude LFO for each oscillator.

Amplitude page

The amplitude page controls amplitude-related settings for oscillator 1 and 2, such as their Attack, Decay, Sustain (ADSR) envelope timings/levels, as well as their amplitude LFOs.

1. AtK.1 Amplitude Envelope Generator Attack Oscillator 1

Attack defines the time it takes (in milliseconds) to ramp up from 0 full amplitude (attenuated by AEG.d).

2. dcy.1 Amplitude Envelope Generator Decay Oscillator 1

Decay defines the time it takes (in milliseconds) to ramp down from full amplitude (attenuated by AEG.d) to the sustain level.

3. SuS.1 Amplitude Envelope Generator Sustain Oscillator 1

Sustain defines the proportion (0-127) of full amplitude (attenuated by AEG.d) that should be sustained during note on.

4. rLS.1 Amplitude Envelope Generator Release Oscillator 1

Release defines the time it takes (in milliseconds) to ramp down from sustain level to 0. Release stage of the envelope generator is entered upon note off.

5. L1.Wv LFO 1 Waveform

Specifies the waveform for oscillator 1's amplitude LFO. Available waveforms are;

• 'nOiSE'; random noise
  
• 'SinE'; sine wave (starts at 0 / 90 degree phase, ramping up)
• 'tri'; triangle wave (starts at 0, ramping up)
• 'SaW'; saw wave (starts at 0, ramping up)
  
• 'Sqr'; square wave (starts at 1 for a half a cycle, then switches off for half a cycle)

6. L.1.de LFO1 depth

Specifies the strength by which the LFO should affect the filter.

Negative values invert the waveform, causing, for example, a square wave to be 0/"off" and then 1/"on", as opposed to the being 1/"on" and then 0/"off" (or similarly a sine, triangle or saw wave ramp down, rather than up).

7. L.1.rt rate for cutoff frequency LFO

Specifies the speed by which the LFO should oscillate. Speed is specified in steps and is thus synced to your song's BPM.

8. L.1.ho hold duration for cutoff frequency LFO

Specifies the hold duration in milliseconds for which the LFO should hold the LFO's sampled value. Combined with the LFO rate this can result in various interesting rhythmic patterns due to aliasing interactions.

9. AtK.2 Amplitude Envelope Generator Attack Oscillator 2

Attack defines the time it takes (in milliseconds) to ramp up from 0 full amplitude (attenuated by AEG.d).

10. dcy.2 Amplitude Envelope Generator Decay Oscillator 2

Decay defines the time it takes (in milliseconds) to ramp down from full amplitude (attenuated by AEG.d) to the sustain level.

11. SuS.1 Amplitude Envelope Generator Sustain Oscillator 2

Sustain defines the proportion (0-127) of full amplitude (attenuated by AEG.d) that should be sustained during note on.

12. rLS.2 Amplitude Envelope Generator Release Oscillator 2

Release defines the time it takes (in milliseconds) to ramp down from sustain level to 0. Release stage of the envelope generator is entered upon note off.

13. L2.Wv LFO 2 Waveform

Specifies the waveform for oscillator 2's amplitude LFO. Available waveforms are;

• 'nOiSE'; random noise
  
• 'SinE'; sine wave (starts at 0 / 90 degree phase, ramping up)
• 'tri'; triangle wave (starts at 0, ramping up)
• 'SaW'; saw wave (starts at 0, ramping up)
  
• 'Sqr'; square wave (starts at 1 for a half a cycle, then switches off for half a cycle)

14. L.1.de LFO2 depth

Specifies the strength by which the LFO should affect the filter.

Negative values invert the waveform, causing, for example, a square wave to be 0/"off" and then 1/"on", as opposed to the being 1/"on" and then 0/"off" (or similarly a sine, triangle or saw wave ramp down, rather than up).

15. L.2.rt rate for cutoff frequency LFO

Specifies the speed by which the LFO should oscillate. Speed is specified in steps and is thus synced to your song's BPM.

16. L.2.ho hold duration for cutoff frequency LFO

Specifies the hold duration in milliseconds for which the LFO should hold the LFO's sampled value. Combined with the LFO rate this can result in various interesting rhythmic patterns due to aliasing interactions.

Context menu

The following context menu options are available on a track's 'AMPL' page;

• 'Copy 1to2'; copies all oscillator 1 Amplitude Envelope Generator ('AEG') settings (including depth) to oscillator 2's AEG.
  

• 'Copy 2to1'; copies all oscillator 2 AEG settings (including depth) to oscillator 1's AEG.
