Funny, what you can find on the web, when you are looking for something completely different:

Never hurts to get all the information available while it's still available.

They could move it or make it an on demand service or whatever tomorrow and the whole lot would disappear.

I think my "IP-police"-friend PT could get nuts with some of the free-ed IP-content like the tube-zipper or the tube-eq.... :twisted:

Hey, and the Tube-Blackfinger - where I didn´t waste my time to trace it - is also there..... :roll:

A real nice collection which helps to save a lot of time....

I was interested in a bunch of those, more recently the Pulsar. All are great but the non-dsp's are a little treasure trove.

:D

Stupid DSP. People are amazed at what the POG can do..... it's just a computer! I wonder what the "Hazarai" opcode is?
They're still cool-sounding effects, but the DSP thing kinda puts it in the same category as some kind of Digitech multi-effector, except it only does one effect. It's cool that they can do that now, but it's not exactly one for analog purists is it?

After all the IP protective discussions... and "don't post pictures" harrasment.

Damn. I've gotta change underwear. This is so cynical.... so awfully cynical.

Hmm... I think DSP chips are the ultimate in IP protection. You can't make a copy of the program running on the chip because it would be a clear case of copyright infringement. If people wanted to clone a DSP based effect, they'd have to start from scratch and write their own program to do the same thing.

I had a chance to discuss this matter with the guys of alesis about 20 years ago....:

"...You can´t get a copyright for mathematic algorithms...and at least a reverb programm is nothing else than a mathematic algorithm...."

now....to mod the glowing Blackfinger with glowing BLUE LEDs <sigh> LOL!!!!!!

Hey, what happened to the FlangerHoax schemo???
seems like it's the ONL(?)Y one missing(??)
ModZERO has about the only gut shots around(?)
GOT Hoax???
Send it here!! :-)

Oh...and if anyone finds the Hot Tubes schemo that would be nice too!! :-)
And, as mentioned previously the tube English Muff'n schemo.
I'm bettin' their all similar....hey, they ALL have 2 12AX7's ! ! !
