With the HD500 it can change the DT amp / cab etc but does not send any info to change the reverb. This remains as-is and  the mix value used by the reverb knob is retained until it is changed.

Now with V2.0 and the great DtEditor the reverb can be changed to Echo, Spring etc along with the decay, predelay.

So if I set the reverb to Spring 73 using the editor, then I do not need to have a DSP using reverb in my presets...?

Of course if another reverb is required then it needs to be changed.

So now I can use reverb Spring 73 via the amp. Delays and Screamer etc using the M9 and FXLoop so that means a lot of DSP for whatever.
