Couldnt find it as a stand alone. Any thoughts where it might be, or would I need to install the version of Cubase to get that plug-in ?

???

Also in the realm of computer ideas, check out a free VST applet called: "KT Drum trigger" Its available at a variety of places on the web. Google. Its a VST which looks at an incoming audio file just as a compressor would (with tons of adjustable parameters) and then generates MIDI messages accordi...

Heya, Here's my first guess at how a system could be pulled together to accomplish whats been discussed so far. G code is normally used to run a CNC, and I am trying to avoid that by using more garden variety ideas. 1) Preview capability 2) Variable pitch based on amplitude 3) Automation assist of c...

Heya, Via my very limited understanding of such things... A stepper motor receives a series of pulses to run. Feed it 1000 pulses and it has moved a certain amount in its rotation. If for some reason it skips over some of these pulses, it will not correct. A servo system senses the position of the r...

Heya, I "have this friend" who has built two CNC machines from scratch. He used the first machine to build higher quality parts for the second. The whole affair is run from a somewhat clunky bit of software on a PC, it was a shareware thing. His brain can be picked. Automating the cutter dropping an...

Yup. LPI for 1k is the same out or in, but doesnt the "land" between grooves need to change for amplitude or frequency ? To avoid cutting over ? That was kind of where I was thinking, as the Neumann system seemed to optimize the available total time on the disk by compacting or expanding the LPI as ...

Heya, "just a delay in the signal to cutter amp so the motor can do its stuff?" Guessing here, purely speculative... while the rpm remains constant, the linear distance the cutter travels per revolution decreases as the cutter nears the center. A static delay would work, but it seems to me that posi...

Heya, It was said: "My 8N has vari pitch from one lead screw 83 to 302 lines per inch" Now this is something that I've been thinking about for a few weeks. The Neumann Lathe had a computer which based variable pitch off of a preview head. as the amplitude or low end content changed, the computer mod...

1000 years from now... someone could use a nail attached to a paper cup and retrieve data off an album. 1000 years from now that same fellow could wrap wire around the same nail (bent back on itself) creating a coarse gap and retrieve data off of magnetic tape (which hasnt been erased) by connecting...

Also of note. Our ears are analog. They convert compression/expansion of air into electrical impules which our brains can process. As an analogy... we "heard" the sabre tooth tiger long before we "saw" it. Often times if we saw it, it was too late and we were dinner. So those cave creatures we used ...

Heya, It was said previously: That is why I said, focus on getting a flat overall midrange response, prefrably by _cutting peaks_ with the eq, moving the sliders below zero. Be very careful about applying compensating boost (above zero) especially at the extreme ends of the spectrum. I would like to...

Greetz, You said: "Yes we can hear the limitations but we can somehow listen through those as opposed to something like a low bit rate MP3 file which is very hard for me to tolerate." Its the swirl which kills it for me. What a low bit rate file does in the top end. It may well do a similar lossy th...

And as a side bar... for better or worse I just won an auction on Ebay for a Presto 6N Lathe (with what appears to be a diameter EQ unit) with pedestal, a 90A amplifier mixer, and another large footprint item to try and find room for. In all... I think its a good thing. Guess this means I'm gonna tr...

Yup.... and Yup. With a properly calibrated and aligned recording system, its goal is that the output should be equal to its input. Not "warmer", "phatter", "more distorted", "more brash or strident", but an accurate representation of its input source. Those who love the "warm and wooly" sound of a ...

Systems vs components

Heya, Todays mini rant, or pet peeve... Maybe its just fueled by economics, but this is something that used to bug the poop out of me. From long association with the Ampex List, and watching perfectly good recording *systems* being parted out as components... the electronics modules being yanked, re...

arcane supplies

Heya, We had the same fears when Ampex bailed their audio tape division. That was a sad day. We speculated that boutique smaller companies would probably buy up the slitting and machining tools needed for creating tape... slury formula and the proper oxide mixes. But it was a dark day when analog ta...

cutting supplies...

Heya, Yes, that makes sense... I will muddle through in the meantime. I do know that my attempt at creating a stylus (version one) was a good learning experience. Took an Edison needle, ground a cutting face with my dremel, ground a couple of facets... and it carved its way through my first ever bla...
