Well, theoretically, since we now know the format of the dynamic data parition (where the EQ settings are stored), it should be possible to achieve this through hijack. I'm a bit wary of doing it immediately;

1) IIRC, There's already some EQ jiggery-pokery going on within hijack when we change sources because of the current Bass/Treble implementation. Since re-implementing Bass/Treble to use the DSP's inbuilt tone controls is next on my to-do list, this issue (if it does exist) will go away.
2) I'm very conciously aware of the existence of 3.0a1 amongst the alpha team, which promises 'exciting new functionality'. Not being on the alpha team means that I don't have any visibility into what they are, and I doubt that anyone on the alpha team could tell me (NDA). I wouldn't want to implement this if it's already in the pipeline. If Rob (or any other Empeg official) wants to confirm that it's not a feature in 3.0 then I'll put it on my list.
