8.3.1. Connecting knobs
To send a data stream from one knob to another the CC number of the knob transmitting
the data must match the CC number of the knob receiving it.
Let say you want to change the amount of Glide on the Microfreak with knob 4 on the
KeyStep 37.
By default knob 4 transmits as CC# 77. To be able to send data to the Glide knob on the
Microfreak which receives data as CC# 5 we have to change the CC# number of knob 4.
Fortunately changing that CC# number is easy:
So If you know the CC# of a synth's knob, you can use that CC# to control that parameter.
The trick is to find out to which controllers your synth responds. You can usually find
information about this in the manual of your synth.
Controlling software synths is usually a lot easier, they will often have a MIDI learn function.
In the example below, we'll assign the Filter Cutoff slider of the DX7 V.
• Open the DX7 V or any other synth of the V series
• Click on the MIDI learn icon in the top right corner. Knobs and sliders that can be
controlled using CC# values will turn purple.
