Re: Considering building an ultimate looper...
A good log pot controller definitely gives more dynamic range than 7 bit
down at the bottom end. Todd had complained about the resolution on
some of the foot controllers. My OWN controller (2
dimensional...btw...) that I build for my korg wavestation years ago and
that I still use in my rig has CRAPPY low end control because indeed
it's controlling midi volume at 7 bits. The analog pots that I used are
certainly better resolution than that. I can see the continuum on a
meter. . So please people..drop the issue. Dont' major on the
minors. It's an issue that is nice to have better res on for certain
types of playing where you want an ominous control in real time. And
that's why I mentioned it. If you don't find any advantage in it yet,
just ignore it. But don't keep bringing it up like I said something
stupid because it's not stupid.
It's the same reason I prefer a prophet 5 over a Prophet 600. The 16
bit dac in the P600 gives a noticeable stone wall drop off at the end of
an envelope. It REMINDS THE LISTENER..that they are NOT hearing an
aspect of NATURE..BUT AN ASPECT OF SOMETHING ...hacked up by software :-)
Some people are picky about that kind of thing and it often relates to
the style of music they do...where they feel the essential nature of
having it feel totally connected with the natural realm and totally
separated from the reminder that software is at work. -Bob
