Ah, libprolooks. I guess it could use some updates from CALF again, so
try to get hold of hansfbaier or kfoltman (both hang around in #lad on
freenode)

I agree with almost everything except the vumeter. They are for analog
equipment, but we're talking digital domain here.

The usual criticism applies: unclear headroom, something like 50% of the
meter for the upmost 3dB, multiple definitions for the needle's attack
and release, just to name a few.

VUmeters are no more than eye candy, if possible, stick to digital bar
meters. It's also worth to have a look at the K metering system, i.e.
K14, K12 and K10.


Unlike Ralf, I support the idea of an inspiring GUI. It's sometimes half
of the creative process to have a GUI which invites you to play around
as long as usability isn't completely ruined.

Also note that sampo is working on some GUI stuff, too, so you could
jump that band waggon:

Especially the last one looks pretty decent to me.
