Question for you

Notice the Google Search box on the right frame? Now take a look at it on SparkleTrain. Which do you prefer for this site? I figure the box on top could be useful, but I haven't done it up until now because I thought it looked a little bulky and took away from the site. Also the whole ads thing, but now I'm having second thoughts. Please post your comments via the comment link below. Thanks! : )

8 Famicons and a 606

Check out this shot of a Roland TR-606 controlling 8 Nintendo Famicons (Japanese version of the NES). Ran into this on this VSE thread. Title link takes you to a post on Kotaku with a link to 6955's site and MP3s. 6955 is a Canadian born Nintendo artist residing in Japan. Oddly, I couldn't find the shot on the 6955 site.

How to make an HPF from an LPF

No title link. Mike Kent sent this to AH. He gave me the ok to post this. I figured others not on AH might like to try it.

"You can probably get a High Pass Filter or Band Pass Filter type of effect
from a modular system that only has a Low Pass Filter. You may need to make
one special patch cable, with its wires crossed to switch the polarity, for
it if your modular doesn't have a way to get reverse polarity outputs.

If you send a signal into a low pass filter and then mix it back with the
original signal with reverse polarity, you can emulate a High Pass Filter.

______ ________
| |--Polarity Switch--->| |
|VCO | _______ | MIX |---------->
|____|---->| LPF |-------->|______|
|_____|

Or:

______ ______ ________
|VCO |--->| |--Polarity Switch--->| |
|____| |MIX | _______ | MIX |---------->
|VCO |--->|____|---->| LPF |-------->|______|
|____| |_____|

The mix levels after the filter are critical. This depends on phase
alignment to cancel frequencies below the LPF's cutoff point. Filters
generally mess with phase so this may not work well on some modules.
Resonance can mess things up, too. But it does work on many systems.

Add another LPF on the end of that chain to get a Band Pass Filter with
variable width (the difference between the cutoff of the 2 filters). Drive
both filters from a common EG to get typical BP sweep sounds.

______ ______ ________
|VCO |--->| |--Polarity Switch-->| | _______
|____| |MIX | _______ | MIX |--->| LPF |--->
|VCO |--->|____|---->| LPF |------->|______| |_____|
|____| |_____|


Regards,
Mike."

Yamaha SY-2 Demo

Via this thread on VSE. That is one thick sounding synth.

Corky Burger's Modular Mayhem Pt. 2

Update to Corky's Modular. If you missed my previous post on him, he's creating a Synthesizers.com modular and sharing the experience vie the ONE 40 FIVE store. Title link takes you to his latest updated including a nice sound sample.

Roland SH-101 - New Flickr Shot

It's interesting. I always wanted a Red SH-101 followed by a blue then grey, but the grey is beginning to look better to me every day. I wonder how the inspiration between colors would differ.

Moog Technical Manual and D.C. systems Mystery Module


A couple of shots in via this auction. Anyone know what that module is?
