I usually start to play and mess around with knobs until i hit a wall or feel frustrated by not understanding in which conditions i should use which parameter or if i want to achieve something precise.
In these last cases i go to the manual.
When i still don’t get it, i ask people. The thread was not especially dedicated to Spatializer, that was one of the examples where i don’t understand one function. I used to have a H4n Pro recorder with this option of mid / side for the mics and i could really hear the differences. In the Spatializer i tried with stereo samples and if the Mid is « active », the SG don’t change nothing to the sound from my own experience. Mostly i would have wanted to widened some sounds, to push them on the sides so they can leave some space in the front stage.
The filter for instance is really praised and i found some nice tips in this thread: The OT Filter Is Awesome : Discuss Tips and i was calling for some other examples in context for all knd of Ot’s Fx, tsettingss you like to use for a special purpose.
