Tips 'n Tricks

 

 

!

 

For optimal sonic performance, make sure the input level is high enough. This also makes 
the envelope generated from the input signal more useful. 

!

 

If the saturation LED starts blinking red all the time, turn the input level down a notch so the 
filter core is not overloaded whith the saturation control turned down – that way there will 
be maximum control over distortion. 

!

 

Tapping only once resets the start of the LFO. This way the tempo can also be set by using 
the rate control and retriggering from time to time with the tap. Beware that if the tap is 
pressed again within 1.2 seconds of the previous tap, the tempo will jump to a new value 
defined by the time between those two taps. 

!

 

When the cutoff is controlled by the LFO, the filter can create phaser-like effects when 
setting the MIX control somewhere between wet and dry. 

!

 

If the saturation is turned up, the corresponding ENV control can be turned left to counter 
the distortion. This will create the unique effect of having less distortion when the input 
signal level rises. 

!

 

This in combination with selecting the FAST A/R envelope can make percussive peaks in 
the audio no more distorted than the overall level. 

!

 

The high sensitivity setting on the envelope generater can be very usefull on more quiet 
audio tracks with rhythmic or percussive elements. This way a full envelope gets triggered 
on each peak which can be shaped with the attack/release controls. 

!

 

The EXTERNAL SOURCE input on the envelope generator is a great way to control the 
filtering of an audio track with a completely different audio signal. For example filtering a 
synth track rhythmically with a drum track (or vocal track...) 

!

 

Setting one or more of the ENV-LFO link switches can create very dynamic filter wobbles, 
especially when the envelope filter switch is set to low- or hipass. Setting the sensitivity to 
high may prove more effective in this setup. 

!

 

When controlling the filter externally with MIDI, don't forget to turn the main filter controls 
to the left. Because these are all analog controls, the MIDI CC data is added to their values. 

!

 

The LFO level knob allways controls the final depth of cutoff modulation. To control the 
LFO level with MIDI, this means the knob has to be turned to the right ('full' setting). To 
reset the MIDI value of the LFO level, toggle the Env-LFO link switch.
