New OCTOLFO, Multipass, & Resonator Eurorack Modules From Tiptop Audio

Also see Buchla & Tiptop Audio 248t and 230t Incoming for new details. As always, check with dealers on the right for availability.

Details on the OCTOLFO, Multipass, & Resonator follow.

OCTOLFO – Eight-Voice Voltage-Controlled LFOs

For all Eurorack users, here comes your mega LFO. And for those of you who have already joined us on our journey into polyphonic patching heaven, this is the one you've been waiting for. The Octolfo consists of eight fully independent LFOs with plenty of controls, lots of waveforms, and the ability to load your own waveshapes. Clock-sync it or let it free-run. Use one-shot cycles of waveforms to create unique envelopes, and reset LFO cycles from your notes. All eight LFOs are available simultaneously on regular jacks and Polytip jacks—both outputs and CV control inputs. CV is mappable to parameters, and the entire setup can be saved as a “preset.” This module brings polyphonic modulation into our new world of polyphonic patching.

Multipass – Eight-Voice Multimode Filter

Please welcome the second filter in our polyphonic series: the Multipass. This one carefully recreates the rare OB-X filter design (not the later CEM-based OB-Xa), delivering the sound of the ’80s and early techno.

It features extended signal levels on inputs and outputs for an even broader tone range. LP, BP, and HP modes are poly-voltage controlled and simultaneously available per voice through Polytip, and via a mixed output jack. Each filter mode has manual gain control via dedicated faders. Frequency control is polyphonic and can be over-modulated by a mono signal with adjustable scaling. With all its poly mod inputs, this filter goes far beyond its classic roots.

Where and how much?

The first batch is ready, and we expect to begin shipping to shops soon. Price will be in the $500–$600 range.

Resonator

An extended design based on the analog resonator from the 1975 Polymoog synthesizer. This classic beauty works with everything from drums to polyphonic audio, adding lush resonating swirls.

There are three resonators, each with a selectable band. Each has voltage control for every parameter, nine CV inputs in total. Multiple gain stages (master input, resonator gain, and mix output) allow fine control and help manage clipping. Emphasis CV range boundaries prevent runaway self-oscillation. A true-bypass switch makes it easy to compare processed and dry signals—perfect for leaving it patched in and engaging only when needed.

Where and how much?

The first batch is ready, and we expect to start shipping soon. Price will be about $245.

How to make a modular polysynth in 62HP: Suggested Systems 8

video upload by mylarmelodies

"In this tutorial/demo I'm going to patch a tiny but 'true' 4 voice modular polysynth step-by-step from scratch, tune it, make it stereo, animate and pan it to bring it to life. I'll also show how to do a paraphonic modular patch (two ways!) and create a bonus Polymoog-style resonator to finish. This one features Vostok Modules who sponsored this video and sent gear I could use! I wanted to see if I could squeeze a 'true' modular polysynth into the Intellijel Palette 62HP case. Turns out, you can."

Ambient Synthesizer Textures with the Moog Polymoog, Oberheim OB-X and Yamaha DX-7.

video upload by Remco Rones

"I first made a track with the Oberheim OB-X and Yamaha DX-7 synthesizers and recorded this on cassette. Then I processed the mixdown with lowpass and resonator filters of the mighty Polymoog. Live take, no programming."

LUMAMIX_Resonant_Mixer

video upload by LepLoop

"The new LUMAMIX it's the last addiction to the Lumanoise family, a four channel mixer with send\return and a resonant equalizer, inspired by the Polymoog resonator section.
Available also in euro rack format 8HP, audio from the camera, more infos: https://lumanoise.blogspot.com/2022/0..."

"Lumamix has four jack\mini jack audio input, jack\mini jack send\return, the send out it's pre the resonant equalizer and the return can be seen as 5° input.

The main output it's mono jack or stereo mini jack, all the channels go through the resonant equalizer where you can select the type of filter, low pass, band pass, high pass and the frequency range low, medium, high. The equalizer can resonate, and the cut-off can be controlled via the Light Dependent Resistor, the LDR can be activated with the switch.

The gain knob set the level before the equalizer.

We can also offer the Lumamix in Euro Rack format.

The Resomix 8HP with 3 input, send\return and cv control over the cutoff frequency."

"Resonator is a Polymoog inspired formant filter that is intended to emulate static resonances that are typical for acoustic instruments. Its three non-overlapping bands have frequency, gain and emphasis or resonance controls.

All three bands can be switched between Low pass, High pass and two Band pass modes (Band pass "notch").

All functions are working except the high frequency band when in BP2 mode."

You can find additional posts featuring the Polymoog Resonator here. The late Jurgen Haible designed the original clone.

"JSI Polymoog Resonator desktop module.

It's essentially the resonator section from a Moog Polymoog.

Here's some info from the JSI website:

'Resonator is a Polymoog inspired formant filter that is intended to emulate static resonances that are typical for acoustic instruments. Its three non-overlapping bands have frequency, gain, and emphasis or resonance controls.

All three bands can be switched between Low pass, High pass, and two Band pass modes (Band pass 'notch').'"

JSI also makes the PROGUE, Moog Rogue & Prodigy desktop synth. This is the first post to feature the JSI Resonator. Curious if it's based on the JH Resonator.

Polymode drone demo - Voltage Modular

boxoftextures

"Another excellent module for Voltage Modular, from Cherry Audio. Kind of a whole synth actually rather than just one module. It's based on the Polymoog, although it has a lot of added features because it's modular, which means you can throw half a dozen LFOs at the resonators, say, if you would ever feel like doing such a ridiculous thing. But who would ever think of doing something like that anyway?

I put together a fizzing and buzzing and moving around drone patch today. It uses the Polymode module, far too many LFOs, and a reverb. Everything's internal to the Voltage Modular app, with nothing external except for an Arturia Keystep, on which I pressed only two keys for the whole thing. You can of course make much more than drones with the Polymode but as soon as I saw all those control voltage jacks on the resonator I knew what I had to do.

The Polymode module sounds great, is quite useful, and is surprisingly inexpensive. Not many of us will ever get our hands on a Polymoog but the Polymode synth module is certainly within the reach of far more of us.

Polymoog undergoing restoration

Published on Jun 12, 2019 SynthDan1

"In April 2019, against my better judgement, my friend Martin and I purchased a broken Polymoog (but aren't they all?). We've fixed issues with the power supply, octave divider chips, and a multiplexer chip in the resonator section. We've replaced all the LEDs and dismantled, cleaned, and lubricated every single slider. There are still a few minor issues (aren't there always?) but the Polymoog has roared back to life, and you can see and hear how great this instrument has become."

Yamaha CS80 Strings - processed through 3 band Resonator...

Published on Feb 4, 2017 noddyspuncture

"Here I have processed my CS80 (#2) through a three band 'Resonator'. Very much like the Korg PS-3100 & PS-3300 resonators and also the one in the Polymoog - but with a lot more control over parameters..! I am only using the CS80's preset string patches with some slight after touch on the oscillators and later on I add the ring modulator."

via this auction

"This Polymoog is the Synthesizer version, not the preset keyboard version. ( you can dial up those sounds as well with this one) In all honesty, it is in exemplary condition! Once owned by Larry Fast of Synergy Serial # 3348. He also owned a prototype Polymoog too. I had $800 exactly worth of service done to it by a qualified synth tech who used to work for Moog in the 70s to get it to where it is now, roughly 95-98% which is uncommonly good for these synthesizers if you know anything about these guys! :) Also, this is a later model, one of the last production runs, which is good because they ironed out most of the bugs by then. I will provide the receipt I received for the repair work. I have not had any problems with this synth, since the work was completed 4 years ago! I will provide at first a rough video demo, followed by a more detailed one which will go over all the Waveforms, notes, VCF section, Resonator section, Trigger in/outs ( you can run another synth or drum machine through its filter)
Variation Mode ( sound building ) Mixing, splitting keyboard, Sample and Hold, A D S R, Pitch shift, tunings, multiple and individual volume controls, ribbon controller, Cutoff, Modulation, and so forth and so on. All of these functions listed above work! A couple of the LEDS do not light up! All 71 keys sound cleanly on all waveforms with the exception of one note, which does not sound on the sawtooth waveform. However, you can combine waveforms and then it resonates at an equal volume. Lastly, however beautiful sounding and iconic these synthesizers are, they are also notorious for not liking to be moved! When for example I move mine from the first floor to the 3rd floor I have to turn it at an angle, when this occurs most times the polycards become somewhat dislodged. I usually only have to apply a small amount of pressure to the roof of the keyboard, to get the synth back to normal! Really funny actually, and it never fails to kick it back in gear. This being said, I would MUCH Prefer not to ship this synthesizer due to its delicate nature. Pick up is most welcomed, and you could even demo it for as long as you want and then afterwards press the magic "buy it now" button! Absolutely NO SHIPPING OVER SEAS!!! Sold As/Is NO RETURNS"

Moog Polymoog Keyboard Synthesizer 203a Prototype Museum Piece

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

via this auction

via the seller: "Well here it folks. I have been holding onto this bad boy for awhile now. Its time for the world to see it. This is one of a few early and prototype Polymoogs I acquired from the estate of Anthony Marchese. He was instrumental in the development of the Polymoog. As well as the X-1 fighter jet. But that's a different story. You may remember the "Polypreset" I sold a while back. This is from the same collection. This appears to be an early mock up of the 203A. It has allot of fully developed parts in it. That are common to just about all 280a's and 203a's. However. The center resonator board is completely hand built. There is also a second hand built board behind the output bank. The other thing unique about this machine is the interface. The left side of the interface is not the same as the production units. This unit does work. Although it does need work. I was able to sound out of all but 3 keys. All voices work. Though they need the 'keyboard response' section switched to variable. In preset mode less than half the voices work. The sound from the machine is less than perfect. But hey its a Polymoog that has not been serviced. Cosmetically the piece shows its age. It can be restored or left as is for collector value. Please check the pics closely for condition. This really belongs in a synth museum somewhere..."

Polymoog 203a Vintage Analog Synthesizer

YouTube Published on Oct 3, 2012 by Sjobeck7

"Recorded / improvised with my Roland CR-68 (Compu Rhythm) on minimal setting.
From the Polymoog I had the direct output and resonator outputs fed into my Behringer mixer while the VCF output was fed into my Ibanez UE 305 with Analog Chorus,Delay and Compressor all engaged and output back into my cruddy mixer.
I was obviously tweaking the sound in spots... Most notably the VCF Cutoff and sometimes S/H rate etc. Towards the end, or somewhere in the middle I brought down the release for a more plucky sound while the lower half of the Polymoog had a bit more sustain... Unfortunately I recorded this to digital (Tascam DP01FX) It sounded much nicer through my Tascam 688 Cassette 8-track but then I couldn't transfer it to this media from there. Also, my Polymoog is only offering out Square waves at this time or else it would have sounded even way more complex and OTHERWORLDLY!!!
I have a feeling the Blondie and Gary Numan mostly used just Squarewaves anyway for their string sound... Though ealy 70's Ultravox relied more heavily on the deeper and fat sounding Polymoog sawtooth waveforms..."
