An Eprom is, I believe, an
Eraseable,
Programmable,
Read
Only
Memory chip.
They state, "
If you do not have the means to write this datafile to a blank EPROM, then you can order a pre-programmed EPROM from your nearest BEHRINGER authorised service centre."
If you haven't the means to write data to one of these chips, I'd leave well alone to be honest mate. There's one available for my Bass V-Amp, but when you weigh up the pros & cons of buying a chip, the chance of it not working or completely trashing the unit, against the sounds that we already have, I think I'll give it a miss.
I'm going to follow your progress on Midi automation and see how you get on with it before taking the plunge.
