For the OPN S by the way, what Richnfamus1 suggested can also be achieved by turning on the OpenSound Booster feature on the ON app. Some folks don’t seem to notice much difference using OSB, but maybe you can. It’s worth a try at least. It’s probably even more aggressive than the “Full Directional” setting.
And Richnfamus1 is right, the volume control is your friend. Beside being in the correct program, if you’re uncomfortable, turn down the volume. If you need more help, turn up the volume. Using the right volume in the Default program for the OPN is probably more helpful than using the wrong volume in a dedicated program. After all, the OPN is designed such that the Default program should work most of the times for you without having to flip around to different various dedicated programs every time you transition to a different environment.
