Playlist: 1. Patch of The Week: The Sonic XV's Wave Folder - So many tones from just 1 VCO's Triangle wave

'Sonic Arps': The Sonic XV Transistor Diode Ladder Filter has a built-in Wave Folder, and in this video I'm using an arpeggiator in random mode to show the many subtle flavours of sound it can achieve from just a simple triangle wave from a single VCO. I will also pull a huge variety of timbres from a sine wave in a similar fashion.
The filter is a re-creation and expansion of the VCF from the Musonics Sonic V (5) synth of the 1970's (predecessor of the Moog Sonic Six), and shares a similar character to that of the EMS Synthi and VCS3, also being early diode filters. Bearing that in mind you might expect it to produce aggressive tones and chaotic feedback, which it can do well enough, but you might not have expected that it can also be very subtle, organic and warm in character, particularly well-suited to melodic arps/patterns and percussive sounds. With the added wave shaping functionality that wasn't present on the original, along with 24dB and 6dB low pass modes, and band pass filtering, this module packs a lot of tone shaping into 14hp.

Patch notes:
Green dots show approximate pot and switch positions. Where a pot has two dots, this illustrates the range I move them during the video. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
I'm using the VCA as a mixer so that I can use the outputs from both the BP and 6dB outputs of the Sonic XV. Notice in the video they are set at different volumes at different points depending on the sound - you will need to adjust this too, as different combinations of IN LEVEL, IN MIX, IN WAVE, and filter settings can make a significant difference to volume levels.
Modules used from left to right: Vintage Transistor Core VCO, Sonic XV, Contour Generators, Discrete Cascaded VCA.

2. Patch of the Week: 'Schulze School' - Melodic Eurorack performance + 'how-to' guide & patch sheet

This week's patch makes use of the V-Shape wave shaper/wave folder to sculpt the great analogue tone of the MiniMod VCO to create some delicate timbres that reminds us of Klaus Schulze's mesmerising sounds created on his sequencer-driven Moog modular synth systems in the 1970's. It also makes particular use of the Ring SM as a sub oscillator generator, and the rich tones of the Sonic XV diode filter.

Check out the AJH Synth playlists for more 'Patch of The Week' videos, which will be either performances or 'how to' guides detailing a range of sounds, some familiar, some less so, and each containing a patch sheet at the end to show you how to construct it for yourself.

3. Patch of the Week: 'Singing Gemini' - Dual Analogue VCF as a Dual Sine Wave VCO How to & patch sheet

This patch uses each of the 2 analogue filters of the Gemini as a dual VCO, self-oscillating, so that they produce sine waves and can be sequenced melodically using the Korg SQ-1 or any analogue step sequencer. This guide shows you how to make this patch, along with a patch sheet at the end. It is one of the many ways you can use just a couple of Eurorack modules to make music, as modular synthesis can be rewarding even with a minimal gear list.

XILS-lab PolyM Polymoog Soft Synth Released

You can find a few videos previously posted here on the XILS-lab label (scroll down to previous posts).

via XILS-lab


"XILS-lab literally creates plug-in pleasure principal when recreating revolutionary polysynth

GRENOBLE, FRANCE: audio software company XILS-lab is proud to announce availability of PolyM — an authentic recreation of the pioneering Polymoog polysynth, dreamed up by American designer Dave Luce and produced by Moog Music between 1975-1980, but benefitting from finest French software skills to truly create a plug-in pleasure principal as arguably the best ‘virtual’ divide-down oscillator technology-toting soft synth available anywhere and teaching the old dog some new tricks in the process — as of July 3...

That’s today. Putting PolyM in its present-day context involves initially looking back. But back in the early-Seventies, setting out to create an analogue, functional voltage-controlled synthesizer that was polyphonic against a backdrop of monophonic mainstays proved problematic for many. Moog’s musical solution came quicker than most, making an appearance in 1975 in its extremely expensive ($5,295 USD), nine-preset original form as the Polymoog keyboard (model 203a). It included a front panel packed with an almost continuous row of slider pots (permitting presets to be fully modified into more individualised analogue sounds via various subtractive synthesis parameters, including a 24dB Moog ladder filter section — allowing modulation modulated from its own envelopes and low frequency oscillation — alongside a unique and flexible three-band resonant filter section with lowpass/bandpass/high-pass filter modes) before being joined in 1978 by a marginally more economically-viable ($3,995 USD), 14-preset stripped back version (with editing reduced to volume, tuning, high-pass filtering, and basic LFO — Low Frequency Oscillator — features), which was also (confusingly) called the Polymoog keyboard (model 280a), though the original fully-variable version was then rebadged, admittedly, as the Polymoog Synthesizer.

Polymoog 203a Keyboard Synthesizer with original 285 Dual Pedal Controller SN 3040

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Polymoog 203a model with 285 controller pedals and legs completely rebuilt by New England Analog in March 2013. Serial number 3040.The rebuild cost $4500 over and above the $2500 I paid for the synth. You can search New England Analog's website and go to service and photo gallery to see the 80 photos illustrating the rebuild. NEA also installed a custom formant filter circuit ( see photo of board with green connecting wires, you can also see the SMPS in gold )built into the organ patch to simulate the Vox Humana patch. NEA also has a YouTube demo of this you can search. Not perfect but if you set the saw and square wave LFOs at different rates using a narrow pulse wave at 2-15% duty cycle and run through a flanger, you can get it to 90% of the Vox Humana patch sound found on the 280 model.

The NEA rebuild includes the following:
Power supply replaced by SMPS which greatly improved the stability. Switched Mode power supplies incorporate a switching regulator to convert electrical power more efficiently than the original Polymoog PSUs. The SMPS generates almost no heat which is a godsend to the delicate internal circuitry in the Polymoog.
Replaced all switch indicators to blue LEDs.
Rebuilt Pratt Reed keyboard with new bushings and lubrication. Polished busbars.
Repaired and calibrated all velocity sensors.
Repaired faulty VCF envelope generator.
Repaired faulty capacitances in middle D modulator, changed several polycom chips to temper voices between notes
Replaced all polarized capacitors
Replaced all analog opamps, analog switches, multiplexers, and all CA 3080 OTA chips.
Repaired faulty Pass Mode switch on front panel.
Lubricated 285 controller pedals( the pedals alone have sold for upwards of $500
The modifications made by NEA with this rebuild added quite a lot of stability to the unit . A few caveats however- if you have never owned a Polymoog, each key has a Polycom card which snaps into a holder.They can vibrate loose during shipping or transport so the new owner must feel comfortable reseating these cards if any were to shift. All you need is a screwdriver to take off the cover and unscrew a PCB , pull off a few ribbon or pin connectors and reseat a card.(see last photo). I've had this Polymoog for three years, moved it four times and only once had to reseat a card. You will be able to tell if a card has shifted. A Polycom card that is loose will typically sound brighter or louder as though the filter is wide open or sound duller like the filter is closed on all patches. You also need to be selective about where you will use the Polymoog. It should be in a room that does not have any ground loop issues and you need to keep your iPad and mobile phone or any other wireless device at least 5 feet away. The Polymoog is susceptible to electromagnetic RF interference and there are some good stories on the Internet about musicians on stage hearing broadcasts coming out of their Moogs during concerts. If you have ground loop issues or a lot of RF interference , you have the option of using the balanced mix output jack which has special shielding to prevent interference. You also need to set the pitch wheel on the pedals at no more than 60% of max when you use it. Yet another poor Moog design that if you use the pitch wheel on the back of the pedals at max wheel setting, the pitch will change so drastically that the tuner on the front Polymoog control panel can't bring it back completely in tune. It can be off as much as a semitone which is the case with this Polymoog."

Polymoog 203a with Vox Humana Program testing (by Synthpro)

Published on Feb 21, 2015 synthpro

"Hello Everyone,

This was a fast video I made showing off the programming changes I made to a 203a, I went by the 280a schematics plus some tweaking of my own to make this 203a blast Vox Humana. I replaced Preset 7 Vibes to be VH and I am very happy with the results. Still have some fine tuning to do before I am 100% satisfied but am extremely close to having it right on.

I was comparing directly between my 280a, (keyboard model/Vox Humana) and a 203a, (synthesizer model)

Thanks for watching and as always I great appreacite all the support, you guys are the reason I make these videos.

Take care,
Jareth"

Andy Baker's Polymoog 203a with Vox Humana preset, (by Synthpro)

Published on Feb 17, 2015 synthpro

"Hello everyone,

I have been working on a polymoog for a friend and decided to try my hand at programming one of these beasts to have Vox Humana. It is still in the rough programming stages and will keep playing with it until I get it matched perfectly.

Ignore the keyboard damage, this is my polymoog chassis that I am currently rebuilding, I stuck Andy's Boards in it so I could troubleshoot/ modify/repair.

Appreciate all the support my friends and thanks for watching!

via the seller: "This synth is really something special. It's received rave reviews in all the magazines and they are completely justified. I was lucky enough to contribute to the sound library and I had a great time working on this synth. They've really covered all vintage bases with this synth. It does an outstanding job of sounding like the great analogues from the 70's and 80's. Arp, SCI, Moog, Roland et al. It can also sound thoroughly modern thanks to the great selection of digital wavetables. Add to that the lovely sounding filters, then on top of that it's awesome FX section. The Perfomance mode is where this thing really comes to life. It's basically 4 stacked synthesizers. So any oscillator configuration is covered from all those classic synths. Here's an example of how I programmed the Vox Humana sound from the great Moog Polymoog 203a. On Program 1 I got a bit of PWM going with the LFO modulating the square waveshape, then added a bit of vibrato so the pitch modulates. On Program 2 I added a saw wave and modulated the pitch slightly with a slightly different rate to the LFO in Program One. Then I whacked on the Ensemble effect and Bam! Instant Numan!"
