MTU should look at that possibility?
There is in fact a Karaoke software that uses a very good sound engine and it does have the option of adding some reverb on the selected input like Line if your Mic is connected to a mixer.
Another excellent option is to use the EAX software that comes with most Sound Blaster product, believe me it does an excellent job & it could perform better than some external device.
The best option would be for Hoster to offer this reverb plug in so this way you don't depend on any other device!!
