Controls and Jacks
Each VCO has the following panel controls and CV inputs/audio output.
Pitch control: COARSE, FINE and 1V/OCT are internally summed together and presented to the VCO as a single CV
source.
FM: this is a separate CV Frequency Modulation input to each VCO. The panel control is a 0-100% attenuator for the
CV applied to the FM jack.
SYNC: this is used as a trigger function input. The action is based on the VCO mode.
CV X/CV Y: each VCO has 2 CV inputs. In the menu system, these are called X1/Y1 for VCO1, X2/Y2 for VCO2, etc.
The applied CV input at the jack is first attenuated by the associated MOD panel control, then summed with the
PARAM panel control. The functions change based on VCO mode.
OUT: the audio out, which is a mixture of all 4 VCOs as set in the Mixer page.

Voice Settings Page
The top level page (shown) is a view of how each VCO is set up. The VCO operating mode is
programmed by highlighting the desired VCO and clicking. This will take you to the settings
page, where the algorithm and CV assignments are set.
The screen shows the default setting when you received the E370.
It is important to note that all 16 CV inputs (1V/O, FM, PARM X and PARM Y for each VCO) and
the 4 SYNC inputs are
fully assignable
and can be used multiple times. Of example, if you
have only 1 pitch CV source available, you can assign it to all 4 VCOs, and it doesn’t HAVE to
be on VCO #1. Any of the CVs can be assigned to any of a VCO’s variable parameters. In fact,
you can for example assign all 4 VCOs to use PARAM X3 in different algorithms, so turning 1
panel knob affect all 4 VCOs in many different ways.
The default is “no sharing”, meaning X1/Y1 are only assigned to VCO1 variables and so on.
Some VCO algorithms have more than 2 variable CV parameters. If you ‘run out’ of assignable
CVs, you can select a fixed 0-99 value (like a static panel knob). For example, the Cloud Mode
has 4 parameters, and default uses the ‘static’ parameters for Chaos (C) and Chaos Bandwidth
(B). Of course, these can be over-written to be any CV source.
Mixer Page
Each VCO output is a mixture of all 4 VCOs. As seen here, the default setting is each VCO is
‘full on’ (a 0dB setting) while the other 3 are muted (‘off’).
If you want a different setting, use the encoder to select a VCO and click. This will take you to
the ‘Mixer Sliders’ page, were you can, in real-time, set the levels for each VCO to be summed
into that output. Use the encoder to highlight a VCO, then click to adjust the level up/down.
The gain structure is designed so that if all 4 VCOs are set to -12dB (second tick mark), that
output is at maximum non-clipping level (~11V pk-pk).
Here is an example for VCO3 having a mixture of several outputs. The numbers at the top of
each slider is that VCO’s mixed level in relative dB (0dB = full level).
Note the sliders have a finer resolution in the 0dB to -12dB range.
Having the slider all the way down mutes that VCO’s mixing. It does NOT mute that VCO’s
output overall: only for this particular mixed output.
