I dont think it sounds “flat” at all… but such non-descript adjectives in regards to music and sound design are almost purely personal in the first place, and therefore the most highly subjective - also as a sound engineer it really gets tiring dealing with this kind of thing when people are saying “it sounds too green” or “it sounds too bloobala” or whatever the fuck… so I usually tend to dismiss these kinds of statements immediately anyways
but in fact the DM12 sounds pretty unique IMO, in that most of the patches seem to really lather on all the effects and so forth, which is honestly a big part of the appeal to me as well - from all the routing options, there are a few that seem to feed the audio back through the filters, etc. - so there seems to be quite a lot possible from that kind of situation… its definitely more of a players synth, rather than a programmers synth tho - no multitimbral, heavy on the instant gratification buttons, etc.
honestly im pretty excited about it but i doubt everyone will love it - doesnt seem like a universal hit
but im probably going to get one asap… who knows
yeh, so “flat” is not how i would describe this, but like i said… lots of placebo and anti-placebo effects in this area
