No it won't sell okay, because there are mixers on the market for under
70 Euros, which offer - though not CV controlled - much more (mic pre
amps, aux sends, level meter, pfl,...). And in the end of the day, the
people will buy the Behringer for 70 Euros instead of the Doepfer for
100 Euros (or even more (think e.g. of the A-129-3 as equivalent in the
production costs), which won't have all these features. No I fear you
will be the only customer to buy it.
