Vermona fourMulator - quad modulation engine - Manual (Page 8)

A fourMulator – what is it?
Simply described, Vermona's fourMulator is a quadruple LFO, with all
LFO units (modulators) being able to run freely or synchronized to each
other. All four LFOs are equipped equally with one exception: LFO 1 can
only act as sync reference to the other three LFOs, while these may act as
sync reference or being synced to their left counterparts.
In addition, fourMulator offers a clock/trigger section. Using this, the
unit can be synced to other clock sources, e.g. an analogue sequencer, or
may act as a sync reference. Furthermore, the unit's user definable and
editable trigger-sequence is a perfect partner to a variety of gate depen-
dent modules.
Technical data
The fourMulator has been designed to work with almost any available
module. For those with deeper interest, here are a few specifications for
newcomers and experts.
fourMulator outputs CV-voltages with a range between +5 and -5 volts, a
total range of 10 volts. Note that some modules are not designed to han-
dle negative voltages. In this case, only the positive voltage will affect the
controlled function. There are also CV-inputs, e.g. for cutoff control of
certain filters, that work within a range of 0 to 10 volts. Although the
total range is identical, the fourMulator's LFOs cannot sweep the full
range. In these cases, using an offset generator is helpful, such as
Doepfer's A-183-2.
Triggers and clock impulses are output with 12 volts with positive slope
and 50ms duration. This specification is accepted by almost all available
modules that accept gate signals, e.g. envelopes, switches, reset-inputs
for LFOs, start/stop inputs for sequencers etc.
The reset and clock inputs accept signals ranging between 3,5 and 12
volts.
