Navs' Modular Lab - Filters

Remember the VCO comparison tests? The next installment is up. Via Navs:
"As promised, it's filters this time: Doepfer + Plan B's Low Pass Gates, Plan B's Model 12 State Variable Vactrol Filter and the mighty Cwejman MMF-1. Doepfer's A-105 SSM makes a guest appearance as control from time to time. Download the zipped folders, have a listen, join the forum and tell us what you think!"

"Real Analog Powerhouse
The Andromedas fully analog signal path is controlled by a high-speed Motorola Coldfire microprocessor, offering 16-voice polyphony with 16-part multitimbral capability. Andromeda features two analog oscillators per voice, with standard waveforms (available simultaneously), suboscillators, hard and soft sync, and more. It provides two analog filters per voice: these 2-pole (multimode) and 4-pole (lowpass) resonating filters are classically-derived designs, and offer you an astounding range of sonic variability.

Andromeda also provides external audio inputs that allow you to route any signal through its filters. Andromeda has three LFOs, each with six waveforms and many powerful features. It also has three 7-stage, 3-level envelopes capable of functions never before found in any analog synthesizer. An extensive mod matrix offers you an enormous freedom in configuring Andromedas sonic firepower, adding to its monstrous capabilities.

In-Depth Control of Your Sound
Andromedas 61-note synth-weighted keypad features velocity and aftertouch sensitivity, and its ribbon controlled offers multiple, assignable functions. A distinctive, futuristic front panel features 72 knobs and 114 buttons (the majority are single function), optimally arranged for rapid-fire tweaking and in-depth experimentation. Andromedas large, backlit LCD display provides real-world values of parameters (time, frequency, BPM, etc.) and high-resolution graphics. No other synth has ever offered such a sophisticated, informative control panel for creating analog pyrotechnics.

Extensive features

In addition to its real analog synth engine and hands-on interface, Andromeda provides a wide range of performance features, including multiple keyboard modes, portamento with nine slopes, and legato functions. For added grins, Andromeda provides a built-in arpeggiator and analog-style sequencer with MIDI sync, high quality digital effects Z(reverb, chorus, echo and more), and a nasty little analog distortion circuit. Internal program memory features 256 preset and 128 user-defined programs. Andromeda also offers a PCMCIA-format memory card slot for additional programs and mixes.

(When I Was A) Kid - EMS Vocoder Track

via synchro1 on AH:
"If you are curious, I have a sample of the large EMS Vocoder. The track (When I Was A) Kid uses the EMS that was imported by EMSA and sold to Stevie Wonder; early 1979, I think. I had about 24 hours access to it before flying it from Boston to LA for delivery. I stayed up around the clock and ran anything I could think of through it."

New York Times Features the FM3 Buddha Machine

"A few years ago, an experimental music duo called FM3 toured Europe, playing a 40-minute set that the duo’s founder Christiaan Virant describes as “very reductionist, very minimalist, very sparse.” He and Zhang Jian, who are based in Beijing, performed on laptops. Some of these compositions were later released on a CD by Staalplaat, a specialty label based in Amsterdam; it sold about a thousand copies. In the context of avant-garde music, that’s not bad: “If someone can sell 2,000 CDs,” Virant says with a laugh, “they’re like a superstar.” So it’s hard to find the right superlative to describe what happened when some of that same sparse music was released again — not on CD but in a little plastic box called the Buddha Machine. Two years later, sales are approaching 50,000 units and still going strong."

JH Frequency Shifter PCB Update

Via JH on AH:

"I've soldered all components to the prototype board of the main FS-1A PCB, and made a quick demo in connection with an old Dome Filter board (that I had originally made for the FS-2). It's all hooked up with alligator clips, and connected to the insert path of my mixing console because I needed a microphone preamp. I think it's a quite stupid demo, but it shows that the new board works, and I think the sound is very clean for a frequency shifter!

New demo (boring, but showing off some of the sound quality):
http://electro-music.com/forum/download.php?id=8848
Older demos (more dramatic);
http://www.jhaible.de/mp3/jh_ber_1.mp3
http://www.jhaible.de/mp3/jh_ber_2.mp3

Unfortunately, I'll have to make a redesign of the main PCB. I noticed that some of the LM13600s I have in the drawer don't work properly, because their gm matching is too bad for that application. In my prototype, I've used a NE5517, and it works perfectly; but that doesn't mean every NE5517 would. So, I'm adding a gm balancing potentiometer to the new design, which will fix the problem, but which means extra investment in another prototype.

I also have ideas for the second board. I'll probably include an extra string of all pass filters, for a deeper Barberpole Phaser effect. And maybe an aread with veroboard-like structure, for everyone to experiment with additions of his/her own. More about the 2nd board later.

I think even though I expect considerably less demand for this project than for the Tau phaser (it's a more difficult project, after all!), the price per board could be similar, so expect something around 55 ... 60 Euro for the set of 2 boards.

JH."
