Right!
However, the easiest way would be to use one of these:
Please notice that Steve is only shipping to the UK for time being – but the Behringer can be bought elsewhere….just do a search for it.
And…..if you want to connect more than one device, you’d need some kind of switch too.
As for the 2nd question – I remember back in the days, that I had a stock external USB drive connected….so yes that should work!
I would however, not recommend it – it will be much easier to use a PC/Mac for this, because you will have to tag the files properly in order to have these searchable and showing coverpics etc on the BS5.
