Phat Santa

Damn. Via Create Digital Music. Title link takes you there.

ASMx-Genie, the Teisco S-110F, and Elby-Designs

Ready for another convoluted post? Here goes... I saw this thread on VSE by piRoN posting some 3DS Max models of his ASM2 design. Go to the thread for another shot.

piRoN's ASM2 Model


So, what's an ASM2. At first I wondered if it was an Analog Solutions or Analog Systems kit, but a little search brought me to the ASMx-Genie page (title link) with the following bit on it:

"The ASM1-Genie is a semi-patched synthesiser offering the user the benefits of a ready-patched normalised synthesiser that is ready-to-run the moment the power is turned on with the benefits of patching options that allow the user to customise the module interconnections for a greater variety of sounds. The ASM1-Genie, in its normalised mode, closely follows the Teisco S-110F although the ASM1-Genie does not include a Ring Modulator or Sample & Hold circuit. Any of the normalised connections may be overriden through the patch connectors and in this mode of operation the ASM1-Genie more resembles a modular synthesiser."

Teisco S-110F? Interesting. The Teisco S-110F falls into the exotic synth list for me. Never seen one in person and don't think I have ever even heard one, but I like the way they look. BTW, if anyone knows where to find samples, please feel free to comment. You can find more info on the Teisco S-110F on the one and only Teisco Synthesizers Webpage.

Teisco S-110F


So three links, two shots, two modular synth manufacturers, a few synths and some nice 3D modeling counts as a pretty convoluted post, right? No? Ok, make sure to also check out Laurie Biddulph's Elby-Designs, home of the Teisco site, the ASMx site and more. : )

Update: Some samples of the S-110F on Bluesynths via the comments below.

Future Retro 777 Shots

Title link takes you to some nice shots sent my way via Ales Toevs. BTW, check out his site for some really nice mp3s of the 777 and more. Thanks Alex!

Blacet Bar Graph



Interesting module from Blacet. Via Synthtopia News.

"The BG is a 20 element LED bar graph display module. It's designed to take some of the mystery out of what is going on with control voltages and audio levels in your modular setup.

The BG 2520 covers -10V to +10V from DC to audio. A "multiple" of three jacks allows signals to be monitored at the same time that they are being used elswhere in the system."

Pro-One Modifications Page

Title link takes you to a page on some nice mods for the SCI Pro-One. There are more shots, details and some pretty impressive samples. Make sure to check them out.



Modification Summary:

  • Replaced the white noise source with a new circuit that provides white, pink, red, and infra-red noise. A rotary switch selects the noise colour.

  • The new noise source can act as a modulation source in addition to its role as an audio signal. A pot sets the noise level fed to the buses. A rotary switch selects whether the noise signal feeds the Direct or Wheel modulation buses.

  • Added a Sample & Hold circuit. The new noise source is the signal input to the Sample & Hold. The LFO square wave is the clock. The Sample & Hold output can be used as a modulation source.

  • The pulse width of the LFO signal can be adjusted from 0% to 100% with a pot.

  • The LFO signal can be inverted. A rotary switch selects LFO non-inverted, LFO inverted, or Sample & Hold as a modulation source.

  • Added a triangle wave for oscillator A. A pot allows manually mixing between the triangle and sawtooth waves.

  • Filter resonance can now be used as a modulation destination. A rotary switch selects from either the Direct or Wheel modulation buses as a source.

  • The filter envelope can be inverted. Inverted and non-inverted envelopes can be applied to filter frequency and the Direct or Wheel modulation buses via two slide switches.

  • The filter frequency signal from the Kenton MIDI interface can be assigned to the Direct modulation bus. A pot sets the signal level fed to the bus.



The circuitry fits on one tiny Rat Shack board. The pots, rotary switches, and slide switches are mounted on the plastic casing between the main panel and the keyboard.

Minimoog Gear P*rn

Title link takes you to a nice Minimoog Gear P*rn thread on VSE. Includes shots of the Moog Mini A, Mini B, Mini C and Mini D. Note the first shots in the thread are from the Moog Archives site, but there are some after that. What's interesting are a couple of shots from Micke of Sun Ra using the Model B prototype (it was never released to production). Also note the Sequential Circuits looking outlines around the different editing sections. After the hop make sure to note the Mini C and Mini D shots with slider for pitch and mod controllers instead of wheels.
