Hello buddies

Can you give me some advice on how to make this effect on the pad sound?
Is it X-Trem and/or Rotor?

It's already at the very beginning of the track.

Thanks and best regards

 

If you are using FLstudio then Grossbeat can do it. It already contains cool volume/time presets

 

It s s an lfo thats modulate a low pass filter. Every synth or sampler can do that. You can use your DAW automation to vary the frequency to get the effect you want if you can’t do that just with your synth.

 

it's a gating triggered by an LFO of some sort as stated, possibly with lowpass filter as stated
I dont know your daw many of the most popular has stock plugins that can make the job

anyhow here's an useful free plugin that can make a gate effect triggered by midi notes

it's very easy to use and works flawlessly

you insert it on the track you need, then open a midi track and point it to the plugin. Then open the pianoroll on the midi track and you can play with your keyboard or program notes roll.

you can add a lowpass filter if needed

 

If its that warble effect you mean then its a LFO on a varying speed. You just need to modulate LFO rate with ADSR envelope. And the LFO of course should be assigned to filter.

 

Steinberg has a plugin for this, which you could use in your daw of choice.
"Chopper" sounds like a tremelo which syncs & mix knob to your taste.https://archive.steinberg.help/cubase_plugin_reference/v9/en/_shared/topics/plug_ref/chopper_r.html
