The Germans have invaded Moog!

"I took this photo of my LP calibration/QC station at Moog on a day when I was checking out my Waldorf Q's waves on the O'scope. I'll post photos of the Q's basic waveforms soon as they are not so standard. Is it Analog or digital envy? ;)"

Jupiter 8 Poly Vs. Dual

via Mok
"OK - here is a demo of the differences between Poly mode (8 voices, mono) and Dual mode (4 voices x 2 channels - stereo) on the Jupiter-8. There are eight different patches that I created - each goes for a couple of seconds on Poly, and then I set it for Dual with both upper and lower outputs on the same patch for a stacked four-voice stereo. Some of these sounds do well in both, while some just love the stacking. The slight differences in tuning over two sets of four voices, combined with the fact that the LFO's don't sync between 'stacks', creates a huge stereo field. I tried to play similar things on each pass (poly vs. dual) and also tried to balance the volumes afterward (as the dual pass was generally hotter). Yes, the JP is a little more difficult to play with "just four voices", but having owned the PEK for so long, I am used to that... I start out with a real basic patch, but each one is sufficiently different to hopefully maintain 'interest'."

Roland Paraphonic 505

Title link takes you to shots via this auction.
Details:
"Roland Paraphonic 505 Analog Synth with Strings, Bass and Synthesizer sections. The synth also includes an ensemble/chorus effect which was also offered under the name Roland Dimension D as a stand alone unit. The Dimension D is valued over $500 alone. Fortunately, this synth has external inputs to run through the chorus effect, which is outstanding. This synth has a very unique sound and the bass is surprisingly fat and warm. I included pictures of the entire front panel so those of you familiar with analog synths should have a pretty good idea what you are working with. The keyboard is split and it is fully polyphonic for strings and in the upper register of the keyboard. The bass sounds are monophonic.

This keyboard is built in a solid metal case, same case as vp-330 vocoder and is in excellent condition. There is one cosmetic and one functional problem worth noting. A thin strip of wood veneer is missing off the left side panel (pictured) and the vibrato slider does not function. The cap has been removed from that slider. Otherwise the synth is in top notch condition and totally functional without any noise or complications of any kind."
Update via the world of next tuesday in the comments: "Well the Dimension D angle sounds like internet hearsay. I had a 505 though I only have a Dimension C in the same place. There is some relationship and probably a plus is the 505 setting III (of 3 settings vs 4 settings on the rack unit) is a far stronger effect than the heaviest Dimension setting. On the downside, like the Dimension C and unlike the Dimension D the 505 is a mono in stereo out device. The D of course is balanced ins and outs, though I guess a lot of people mostly use it mono to stereo."

Multi-Touch for Windows?

Odd how this stuff comes in waves. Just below I read on Music Thing about the Loop Arena Multi Touch Console. We know about Reactable and the Lemur. Rumor has it that Microsoft might be announcing PlayTabe, "Microsoft’s 'Milan' multi-touch and gestural interface technology" tomorrow.

"'The idea is to take that (Milan) effort and move it into multiple different environments,' said one of my sources. 'It’s not just for the home. They want to see what kinds of commercial environments' might provide a good home for the multi-touch/gesture-recognition technology, as well."

Yep, I can see some uses for this alright.


Update: It's official. You can find more info here and here, with video, and to the left is an ihref="mage from Gizmodo.
