If you have Cubase Pro 14 it can be done.
Let’s use the Low Cut filter from a channel’s Pre section.
You will also need to create a MIDI track for sending the MIDI data.
- load the modulator “ModScripter” onto your audio channel, where you want to perform the low cut.
- In ModScripter load the preset “MIDI Note Play Frequency”
- switch on the Low Cut filter in the channels’ Pre section.
- connect the ModScripter to the frequency setting of the Low Cut; set the connection to uni-polar, the value knob to the minimum position (here 20 Hz) and the depth to 100%
- create a MIDI track; set the track’s output to the ModScripter
Now the frequency of the low cut filter will follow what you play or send on the MIDI track.
