MALSTRÖM SYNTHESIZER

Sequencer Control
The Sequencer Control CV and Gate inputs allow you to play the Malström from an-
other CV/Gate device (typically a Matrix or a Redrum). The signal to the CV input con-
trols the note pitch, while the signal to the Gate input delivers note on/off along with
velocity.
! For best results, you should use the Sequencer Control inputs with
monophonic sounds.
Gate Input
These inputs can receive a CV signal to trigger the following envelopes:
• Amp Envelope
• Filter Envelope
! Note that connecting to these inputs will override the normal triggering
of the envelopes. For example, if you connected a Modulation output to
the Gate Amp in-put, you would not trigger the amp envelope by playing
notes, as this is now controlled by the Modulator. In addition you would
only hear the Modulator triggering the envelope for the notes that you
hold down.
Modulation Input
These control voltage (CV) inputs (with associated voltage trim pots and A/B selector
switches), can modulate various Malström parameters from other devices, or from the
modulation outputs of the same Malström device. These inputs can control the follow-
ing parameters:
• Oscillator Pitch
• Filter Frequency
• Oscillator Index offset
• Oscillator Shift
• Amp Level
• Mod Amount
• Mod Wheel
Modulation Output
The Modulation outputs can be used to voltage control other devices, or other param-
eters in the same Malström device.
The Modulation Outputs are:
• Mod:A
• Mod:B
• Filter Envelope
Routing external audio to
the filters
The audio inputs on the back of the Malström allows you to connect any audio signal
to the filters and Shaper.
To use this feature, it’s important to understand the following background:
Normally the Malström behaves like any regular polyphonic synthesizer, in that each
voice has its own filter. The filter settings are the same, but each filter envelope is trig-
gered individually when you play a note.
However, when you connect a signal to the audio inputs, it is routed to an “extra” filter.
The envelope for this filter is triggered each time any of the other filter envelopes is
triggered. In other words, the “extra” filter envelope is triggered each time you play a
note on the Malström.
There are two different uses for the audio inputs:
Connecting an external signal source
Connecting an audio signal from another device in the rack to the audio input allows
you to process the signal through the filters and/or Shaper of the Malström. The pro-
cessed signal will then be mixed with the Malström’s “own” voices (if activated) and
sent to the outputs.
The result depends on the following:
• To which jack you connect the signal.
• Whether the filters and/or Shaper are activated on the front panel.
• The routing button for filter:B.
If this is activated and you connect a signal to the Filter:B input, the signal will be
processed in filter:B and then sent to the Shaper and filter:A (just as when routing
Malströms own oscillators on the front panel).
Note again that the filter envelope is triggered by all voices. To make use of the filter
envelope, you either need to play the Malström or use gate signals to trigger it or the
filter envelope, separately.
