flight of harmony Infernal Noise Machine, Manual

13/24

INM-Exp

The INM-Exp is an additional set of  five waveform 

outputs and three frequency controls for the Infernal Noise 

Machine. 

The toggle switch selects how it is controlled: When set 

to 

Exp

, the LFO output is controlled only by the expansion 

module and is isolated from the main unit, overriding and 

ignoring the CV+Mod source from the main INM-E. 

Tune

controls the frequency, just as the one on the main INM-E, 

and CV is the level control for the CV input jack. 

When set to 

INM

, the LFO tracks the CV + Mod 

signal in the main INM-E as per usual and the INM-Exp 

knobs and CV jack are disconnected from the system; 

they do nothing. The LFO works as normal, but with the 

LFO waveforms additionally available from the INM-Exp 

jacks.  This means the LFO tracks the 1V/octave VCO to 

some degree, but the LFO is not 1V/oct, so don’t expect 

flawless tracking.
In specific:

With INM-E VCO toggle set to 1V/oct and INM-Exp set to Exp:

•  INM-E VCO outputs are 1V/oct rate, tracking CV +Mod 

source as explained in original description.

•  INM-Exp outputs are LFO rate, tracking the INM-Exp Tune + 

CV jack, no modulation from the main INM.

With INM-E VCO toggle set to 1V/oct and INM-Exp set to INM:

•  INM-E VCO outputs are 1V/oct rate, tracking CV +Mod 

source as explained in original description.

•  INM-Exp outputs are LFO rate, tracking CV +Mod source 

as explained in original description, INM-Exp knobs and 

CV input are disabled.

With INM-E VCO toggle set to LFO and INM-Exp set to Exp:

•  INM-E VCO outputs are LFO rate, tracking the INM-Exp Tune + CV jack, no 

modulation.

•  INM-Exp outputs are LFO rate, tracking the Exp Tune + CV jack, no modulation 

from the main INM.

With INM-E VCO toggle set to LFO and INM-Exp set to INM:

•  INM-E VCO outputs are LFO rate, tracking CV +Mod source as explained in 

original description.

•  INM-Exp outputs are LFO rate, tracking CV +Mod source as explained in 

original description.
