Synth1 Triggering

This has probably been asked before, but I started using renoise a few days ago and didn’t find it on search, so:
How do I make the saturation for instance in synth1 to change during the song through automation or the effect commands or any possible way?
There must be some way to tweak the synth1 effects throughout the song to create some versatility, but I can’t seem to figure out how.

Thanks in advance, renoise sure seems promising. B)

use the MIDIccDevice or VTSAutomateDevice.

add one of tehm on a track and link it on synth1 instance.

If you don’t know about these Meta Devices, search for them on ReNoise help file.
