Arp 2600: Jim Baker Crosses His Wires

click here for the video on Gearwire.
"Improviser Jim Baker uses the Arp 2600 to make unique sounds in his curious brand of "folk music." In this introductory video, Gearwire's Gretchen Hasse catches up with Baker late one Tuesday evening after his set at Chicago's Hotti Biscotti - actually a bar, not a coffeehouse - and he recollects how he came to use the Arp. We also have rare footage of Baker in performance with a sax, upright bass and drums. Check it out in the Gearwire video."

JoMoX M-Resonator Demos

Demos via Ookpikk - Ookpik

"The first demo goes through each different part of the M-Res, basically breaking it down into comprehensible chunks, the second and third are on a drum-loop and a whole track, and they're much more subtle than, say, REwire's Sonic Trio demo."


M-ResDemo1.mp3
"This demonstrates the individual parts of the M-Res, e.g. what the filters sound like, how the envelope follower reacts, what the phase-inverting feedbacks do. In many ways, this is the most informative of the three. The sounds are coming out of the Nord Modular first, sequence is a simple sawtooth except for the distortion demo, and the pad is something a little more complicated."

M-ResDemo2.mp3
"This is a MDUW drum track through the M-Res."

M-ResDemo3.mp3
"This is a full track (or a part thereof) through the M-Res to show how much more fun it is than filter-sweeping a track."

AFG (Audio Frequency Generator - VCO)

Via Mark Pulver on AH:
"Livewire is ready to release the AFG (Audio Frequency Generator - VCO). This is looking to be the hottest VCO on the market.

The the Chaos Computer first showed up at Musikmesse 2006, looks like the (next!) ultimate random voltage generating machine. Mike is saying that it _will_ be out before the end of the year.


Then there was an inference that there may be other goodies released before those.

Allen & Heath XONE:VF-1

"The XONE:VF-1 is a high quality, 1U rack analogue filter unit equipped with a wide range of input and output connectors, which features an enhanced version of the legendary XONE Filter circuits. An RIAA preamp version - the Xone VF-1R - enabling direct connection to turntables, is also available.

Live Perfomance
The VF-1 is designed with live performance in mind. It offers the artist control over the music and the creative experience. The valve overdrive option gives the “dirty” sound to bass and synthesized sounds giving added depth and “fattening” of the sound. The filters can be linked to another VF-1 for control of both VF-1 units by one control as well as the ability to link VF-1's to a Xone:92 and control the VF-1 filters from the Xone:92. As well as the valve overdrive there is an envelope follower giving added effects to a live performance. LFO is also included for an automated response of the filter cutoff, and many filter types are included. Superior sounding Filters associated with valve analogue circuits (e.g warmth, clarity and depth) with the features and control of digital equipment.

In the Studio
The VF-1 is an ideal addition for the studio, be it project or professional. The Filters can be used to remove unwanted sounds (e.g. low frequency rumble) or as an effects processor with tube (valve) front end for added warmth. MIDI implementation means that filter sweeps can be recorded and replayed from a sequencer. The VF-1 can be controlled from external MIDI equipment and can also manipulate MIDI equipment, offering exceptional flexibility from an analogue filter."

"Interfaces: 1 Audio out (mono) 1 MIDI In, 1 MIDI Out Synth capabilities: Digital Phase Distortion synthesis 8 Oscillators, up to 4 per sound Effective polyphony: 4 4-part Multi-timbral Keys: 49 mini, not velocity sensitive The Casio CZ101 was a popular entry point into the world of digital synthesis, putting a surprising amount of power into its home-keyboard style case. The unit's Phase Distortion technology is capable of some surprisingly complex sounds, including chunky bass, not least owing to the fact that up to 4 oscillators could be combined into one patch. This would reduce the polyphony to a mere 2 parts though! The 101 came with 16 presets and 16 user patches, which could be edited and stored via SysEx. Close siblings to the CZ101 included the CZ230s which came with a pattern-based sequencer, and the CZ1 which had a full size keyboard and double the number of oscillators. Bottom line is this is practically showroom perfect which is very difficult to find in this condition. It has a nice 80's synth feel and supports midi. Various patch editors out there allow easy patch transfers back and forth."

Yamaha CS15

images via this auction.

"It's basically a 2 oscillator (VCO) synth with almost two of everything. It has 2 multimode filters (Low, Band and High Pass), 2 mixers, 2 VCA's and 2 Envelope Generators. It also has an LFO with three selectable waveforms and it goes from super-slow to super-fast. It actually reaches audio speed so you can do basic filter FM and get pseudo ring modulator type sounds.

There's also selectable Noise and External Input, so you can plug in your guitar, other synths, whatever and play it through the filters of the CS-15. I've put my guitar through it many times and get an excellent analog tone out of it. From nice clean filter sweeps through to classic 70's overdrive. Very nice!

The filter is 12db so it won't self-oscillate on it's own but I discovered that by plugging the Output into the Input, you effectively have a filter that self-oscillates for screaming effects and sub-bass. Don't worry, it doesn't hurt the synth!

It really is a thoroughly flexible synth with 38 knobs and 10 sliders for manipulation of your sounds. It does very convincing Moog type leads, basses etc but I had much fun doing experimental music with it. By doing the aforementioned output-to-input plug, and modulating the oscillators with the 'sample and hold' LFO and hooking it up to a cheap reverb, much weird fun was had!"

MIDI 9 - Add MIDI to Any Keyboard Instrument

"MIDI 9 liberates your acoustic piano by allowing you to connect your piano to a computer based synthesizer.

MIDI 9 has discontinued its KS MIDI systems. MIDI 9 is now shipping our new MIDI 9 designed QRS PNOscan all optical sensor strip.

The PNOscan will easily fit in any piano. It has no moving parts and has a much lower profile then our previous KS systems had.

The lower sensor strip height now greatly simplifies installation in Rhodes pianos and organs, including tone wheel Hammonds. When installing in double manual organs, one control box can now handle two 61 note sensor strips, saving space and cost.

See what our products can do for you today."

From the Syntar to the MMM Phoenix

In case you missed it, click here for a letter from George Mattson on the MMM Phoenix series analog modular synth. I thought I'd pull some highlights from the letter below, but please do read the full letter. You can also find a detailed spec list for each module available for the system here, and you can find more info on the Syntar here and here.


"My name is George Mattson.
30 years ago I developed and manufactured a performance oriented analog synthesizer I called a Syntar. The synthesizer was innovative at the time, met with limited success and has recently become a topic of conversation in a variety of synthesizer forums.

Due to the growing abundance of new, analog synthesizer enthusiasts, I have been asked to return to manufacturing.

I took the core circuits of the Syntar (thus, the Phoenix Series) and designed a new format; a portable, true analog modular synthesizer specifically budgeted for the new market."
[Matrix: note the analog of the Phoenix rising out of the ashes of the Syntar.]

Some highlights on some unique modules to the system.

"Signal distribution: I do have one major design philosophy quirk. I don’t like passive multiples-period. Using a passive multiple for signal distribution degrades the signal. Using a passive multiple as a “mixer” sums the signals together and can lead to overloading the input of the destination module. I designed two new modules to replace these functions:
The 4X-1X2 buffer: Sort of a buffered “splitter”. It can take 4 different input signals and split them into two output signals for each channel. Each signal is buffered so, the signal is rejuvenated and doesn’t degrade. I took the liberty of cascading the channel outputs into the input of the next channel. So, if a signal is patched into channel 1, it is available on all 8 outputs until the chain is broken with a subsequent channel input. Then, the original signal is available on the preceding outputs while the new signal is available on all of the remaining outputs. It sounds weird but, once you’ve used it, you wonder how you were able to get by without it.

The 4X Mixer: The “other function” replacement of a passive multiple. The mixer has four inputs and actually two outputs, an inverting and a non-inverting output. I designed the mixer to be used for either audio or control voltage signals. This allows for precise adjustment of an audio mix or, a real nifty way to build complex control voltages by using multiple CV sources. In order to add a bit of excitement, my audio mixing days came back to me and I added a “punch-in” pushbutton on each channel to allow for an abrupt addition or elimination of the channel signal into or out of the mix. This is usually a subliminal function but, makes a big difference in audio or CV real-time control.

Filter: The Syntar utilized the SSM 2040 filter. They’re not available anymore at any kind of reasonable price or in guaranteed quantity. Since I had plenty to do with the rest of the system, I was able to get a custom filter designed specifically for this system kindly and graciously by Synth DIY guru Jim Patchell. He designed a 4-Pole 24dB/Octave state-variable multi-mode filter for this. That’s synth-speak for WOW. It sounds great. Thanks Jim. Way to kick a--!

Keyboard control: OK, I had to make some concessions here. Rather than designing an analog keyboard input module and trying to find and stock keyboards (they’re hard to find anymore in small quantities), I went digital and provided a MIDI-CV input module. It’s actually integrated into the power supply module, which makes this a double-wide module and isn’t available as a stand-alone module. I originally designed the system using a commercially-available MIDI-CV controller but, it had limited function, the manufacturer was hard to communicate with and they didn’t want to give me any reasonable OEM pricing. Sooooooo, I had a MIDI-CV controller designed to my specifications by Scott Rise of Division 6. This turned into one of the coolest modules. (even if it is d*g*tal) Read the module descriptions for a full description. This allows the owner to use any MIDI generating keyboard they desire, or any MIDI generating sequencer control. Mmmm- 16 systems, each utilizing a different MIDI channel. Yes, it blows the “Basic and inexpensive” philosophy out the door. But, it was actually less expensive to design and manufacture than pay the “not-so-OEM” pricing offer’s I was quoted for something less versatile. We all win. I’m negotiating with Scott (a nicer way of saying “convincing”) to produce versions of this in other formats or stand-alone units and allow me to offer them for sale on the web site." [Read this thread for more]. via Scott in that thread: "The rumors are true; I will be coming out with a standalone version of the MIDI-CV converter. As far as an exact time frame, I'm not entirely sure yet. I need to get through the MMM launch stuff first.

I also want to get some input from people like you who might possibly have a need for such a converter or are already using one. What would you like to see it do? Now is your chance to help shape it and make it useful. The initial version is going to be based on the one I designed for the MMM but some things will need to be different. For example, should the mod wheel continue to drive a separate 0-5v output or should it modulate the main CV? Does it need an S-Trig output?

Later down the road I will be making a multi-out version that has even more features, so even if your suggestions don't make it in this version they would probably make it into the next one."

Wiard 300 Series VCO

via this auction

"The Classic VCO is the highest quality analog oscillator module ever made. It produces the standard classic analog waveshapes -- sine, triangle, sawtooth and pulse with pulse width modulation. It also has a unique random voltage output which provides 64 random voltage levels. In the audio range, this sounds like "noise" of various colors depending on the tuning of the oscillator. In the "low" range, it can be used in the same way as a noise generator feeding a sample and hold. The Classic VCO has three exponential control inputs, one with attenuator. It also has an AC coupled linear input with attenuator and a propotional sychronization control with attenuator. In addition, this module contains a simple attack-release envelope generator (which can also be used as an envelope follower or lag processor) and a voltage controlled amplifier (VCA) with two mixing inputs. The VCA is intended to be used with the "Velocity" output of a MIDI to CV convertor but can be used as a general purpose VCA. The modulated pulse output is normalized to one VCA input while the output of the envelope generator is normalized to the VCA control input. Red and Green Bicolor LEDs monitor three of the waveform outputs and the voltage output of the envelope generator is displayed by the brightness of a fourth LED. The output level of the VCA is displayed on a four LED VU meter. The Classic VCO module contains: A five waveform pure analog oscillator An Attack-Release Envelope Generator. The envelope is set by an internal jumper for either exponential or linear envelopes. A Voltage Controlled Amplifier (VCA) A jack multiple"

Roland 100m 175 Triple Vactrol Filter

via Ryk:
"The module has three separate Bandpass Filters controlled by Vactrols, based partially on the famous Korg PS3100 resonator circuit, with additional individual resonance circuits and mix section.

They are internally patched in parallel with linked audio inputs, and mod buses, to act as a traditional resonater type filter setup.
When jacks are inserted into the audio inputs and mod inputs they break the routing and the filters can be used separately with individual inputs, freq. modulation, and individual resonance controls.

The same is true of the outputs, where they are internally patched to be mixed to one output via individual level faders, or routed to separate outs, by inserting a jack in the relevant output socket."
