About the three modulation routing types
As described in the tutorial, the principal operators of the Modulation bus routing system are as follows:
• You have Modulation Source, Modulation Destination and Modulation Amount parameters.
• Optionally, you have a Scale parameter controlling the Modulation Amount, and a Scale Amount that governs
how much the Scale parameter controls the Modulation Amount.
There are three different types of modulation routing busses available in Thor:
D You have seven “Source –> Destination –> Scale” routing busses.
These are the seven rows in the left half of the Modulation section, as covered in the tutorial.
D There are four “Source –> Destination 1 –> Destination 2 –> Scale” busses.
These are the four top rows in the right half of the Modulation section. This works after the same principle but the
Source parameter can affect two different Destination parameters (with variable Amount settings) and a Scale pa-
rameter that affects the relative modulation Amount for both Destinations.
D Lastly, there are two “Source –> Destination –> Scale 1 –> Scale 2” busses.
This means that a modulation Amount can use two Scale parameters.
An example: You have the Mod Envelope as Source and Oscillator Pitch as the Destination (Amount set whatever
you like). As the first Scale parameter we use the Mod Wheel (Amount set to 100 so that no modulation is applied
when the Mod wheel is at zero), and LFO 1 as the second Scale parameter (Amount set to whatever you like).
When you move the Mod wheel, the pitch modulation amount will be modulated by both the Mod Envelope and
LFO 1 simultaneously.
