Ducker Atten = 80dB
Ducker Thrshld = -54dB
Ducker Rel Time = 1.0ms
The problem is that between your chords, depending on your play, the ducker will release with that setting (as the release time is set to almost instant).
There's two ways to fix that:
Increase the release time or set the ducker treshold higher.
Try this setting; works pretty good for me:
Atten: 30dB (you don't want the attenuation too high, because then the ducker will have a 'blocky' fadein
Rel Time: 20ms
Trshld: -40dB
Also, you can manually create a ducking delay that is fed with an ADSR for the input gain of the delay.
This has some advantages over the ordinary ducking delay:
- When playing leadparts, your delay starts more early
- The delay is unaffected by any changes in volume or distortion
The best results can be achieved if you set the sustain time of your ADSR to the note value of your rhythm part. Attack almost instant, release almost instant.
Then map your ADSR to your delay input gain, but reverse it (start is 100%, end is 0%).
If you now play a note, the delay input will be muted for like an eigth note and then almost instantly kick in.
Remember than you need to set the retrigger mode to on and find a good value for the ADSR treshold.
You can basicly also use an envelope filter, but then I recommend feeding the delay with the dry guitar signal, so that the feeding signal decays faster.
