DOSBox patch now incorporates three new configuration options:
mt32reverb.mode, mt32reverb.time, mt32reverb.level
If mt32reverb.mode set to "auto", there is no changes in behavior.
One more note: the current implementation doesn't freezes reverb settings completely. When mode 3 is set and the game sets another mode itself, reverb mode will be changed in accordance. And vice versa. However, when you set mode, e.g. 2, and the game sets mode, e.g. 0, your settings will be preferred 😀 I think after we've cleaned up the reverb code, this problem will be gone, eventually...
Option mt32rate was finally deleted since you cannot get with it anything except the loss of quality and emulation accuracy 😀
