Audio Damage Mangleverb - Manual (Page 11)

In the MIDI mode, the SENSE knob acts as a threshold control. If the velocity of a note is below the
setting of the SENSE knob, the note is ignored. If you leave the SENSE knob at its full anti-clockwise
setting, all notes generate gate signals for the envelope generator. Turning the SENSE knob up raises
the threshold, blocking notes with low velocities and passing notes with high velocities.
In order for this mode to work, you’ll have to route MIDI data to Mangleverb. How exactly you do this
depends on your host software so we’ll have to leave this part to you to figure out.
 SIDECHAIN – In this mode, a signal other than the plug-in’s input drives the envelope follower. This
other signal can be any other signal present in your host’s mixer—another track, a send buss,
whatever. Hence you can use the sidechain input to do fun things like open and close the filter with a
kick drum, create reverb that blooms between vocal phrases, and so on. The SENSE knob acts as a
gain control for the signal; turning it up boosts the level of the signal before it enters the envelope
follower.
Support for sidechain inputs in plug-ins varies significantly between different host programs. It may
take some experimentation with your host to figure out how (or if) it supports auxiliary connections to
plug-ins. To cite two popular hosts as examples: In Ableton Live, the sidechain input will appear as a
destination on the lower “Audio To” popup menu once you select a track containing Mangleverb with
the upper “Audio To” popup menu. In Steinberg Cubase, Mangleverb shows up as an LCR surround-
capable plug-in; its Center input is the sidechain input. Hence you can insert it on a LCR surround
group track, create a child buss for that track, and route signals to the Center child buss to feed the
sidechain input.
 LFO – The LFO mode sends a signal derived from the LFO to the envelope follower. The signal is a
pulse wave that’s either off or on. If the LFO’s output is at half of its maximum value or greater (i.e.
above the middle of its display), the signal sent to the envelope follower turns on. If the LFO’s output
is below the halfway point, the signal turns off. This happens regardless of the setting of the LFO’s
WAVEFORM switch. If you just figured out that the signal sent to the envelope generator will be the
same as the LFO’s output when the WAVEFORM switch is set to SQUARE, you get a gold star by your
name today. While the envelope follower always receives a square-cornered wave from the LFO, you
can use the ATTACK and DECAY knobs to turn it into something smoother, thus producing a
modulation signal that is synchronized with, but different from, the LFO.
The knob labeled HPF controls a high-pass filter positioned before the envelope follower’s input. Turning this
knob up cuts low frequencies from the signal, making the envelope follower respond only to high-frequency
portions of the signal. For instance, if the signal is a drum loop, turning up the HPF knob will tend to make the
