To summarize:
• The Matrix is where you route sources to destinations. It's also the place where
you mix several sources together to control one common destination.
• The encoder is bipolar; you can set up positive or negative modulation and set
modulation strength.
5.3. Freaky ideas
It's mostly not good practice to modulate a destination at full force. The right amount of
modulation adds subtleness and expression to your patches. If you get this right, the Matrix
is a treasure trove of unusual finds. Some ideas below:
Change pitch scope:
Without making any connections on the Matrix the keyboard or a sequence will already
modulate the pitch of the oscillator with 1v per octave. If you take a sequence and add
that already existing modulation on the Matrix (route Key/Arp to Pitch), you can drastically
change the pitch scope of the sequence. Steps that were one semitone in the original
sequence will now be 2 or even four semitones. When you apply negative modulation, the
step distance will shrink to microtonal proportions.
Summing modulation signals:
Both envelopes: the Standard Envelope and the Cycling Envelope are sources for modulation
in the Matrix. You take advantage of that by mixing their output to control the same
destination. Why would you do that? By mixing the control voltages, you create a complex
envelope that can control the filter or arpeggio rate in unexpected ways.
Another summing idea:
When you sum two modulations to control one destination the result will usually be
unexpected and surprising, like when you mix the Cycling Envelope and the LFO that you
are using to modulate the Filter Cutoff frequency. You're using the Matrix as a modulation
mixer in this type of patch.
Modulating the Digital Oscillator:
This will probably become one of the most used techniques on the MicroFreak: modulate
Wave, Timbre and Shape of the Digital Oscillator with the (unsynced) LFO and Cycling
Envelope. By letting them control different aspects of the Digital Oscillator with different
speeds you can create ever-changing timbre patterns that never repeat.
Regular automatic transpositions:
For automatic transpositions of a sequence modulate Pitch with the Random wave of the
LFO, or with a slow-moving square wave if you need more regular automatic transpositions.
The square-wave technique will also work with a sequence.
Modulating Modulation:
As mentioned before you can modulate the amount of modulation of a connection point on
the Matrix with the Sequencer modulation tracks. You assign a matrix point by holding any
assign button, then move the matrix encoder. The moment you release the assign button,
the matrix point will be set as a destination. Again the LFO and Cycling Envelope are ideal
means to modulate these points.
