I wish the reverb effect was more dense with more options to control it, but it is currently not at this stage of the app so I must find a way around it; and well I have.
Using an old trick I used with my older Korg workstations..... add a vco modulation to your sound be it a pad or quick stab or percussion sound. By vco i mean pitch modulation.
In Caustic wether using pcm synth or subsynth, set up a vco mod with the second lowest notch on the Rate dial and the second lowest notch on the Depth dial.
You may not hear the pitch modulate but your delay or reverb effect will and greatly enhance your sound and stereo field
Try it for yourself...
