I don't want to fan the flames here, especially as I do not have any horse in this race, but perhaps for future events I think this thought might be worth throwing in the mix, it certainly reflects my preferences ...
It's a good idea, obviously if you don't have a retired box you can't participate, but to level the playing field i'd have said that the rules should take this sorta shape
One device (even if you have two, this makes it fairer to those that don't and forces creativity)
Recorded direct from main outs
Performance should theoretically* be replicable exactly and performable by anyone with the same device using a submitted midi dump (i.e. this completely precludes non standard imported samples but allows internal re-sampling) - *(what cannot be submitted in a midi file is live performance tweaking)
normalisation performed by organiser, if needed, nothing else IMHO
this seems purest/fairest to me, if you start to lean on samples and daw magic enhancements then you blur what the device truly is doing
as I said, I can't join in and these are ideas no doubt endlessly mulled over in the other thread so sorry for stirring it up after the fact
