fourMulator - overview and functions
Simply described, the fourMulator is a quadruple LFO, with all LFO units (herein after referred to as Modulators)
being able to run freely or synchronized to each other. All four Modulators are equipped equally with one
exception: Modulator qcan only act as sync reference to the other three Modulators, 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. our qMI 2 - quad MIDI interface's clock outputs, 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 dependent modules.
The fourMulator has been designed to work with almost any available module. It 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 handle
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 Modulators cannot sweep the full range. In these cases modules with the
possibility of generating offset such as our Dual Buffered Multipe/Inverter or twinVCAmp will help.
Triggers and clock impulses are output with 12 volts with positive slope and 10 ms duration. This specification is
accepted by almost all available modules that accept trigger or 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.
