Roland JUNO-6 with Tubbutec-66 Mod: Demo of some favorite features

video upload by thesrabbit

"A few months ago I had the Tubbutec-66 mod installed in my Roland JUNO-6. I did the full install, except for the CV input option. The basic install provides MIDI In/Out and some fun voice features like detune, different play modes with oscillator stacking, and portamento among other things. The full install adds three additional filter modulation sources: an audio rate triangle LFO, Sample and Hold (can be sync'd to MIDI clock), and a loopable global envelope. I think the loopable envelope is my favorite, just because the full ADSR (plus hold) makes it easier to dial in the modulation you want.

I used my favorite little effects box, the Audiothingies Doctor A for delay and reverb.

Some parts drag on a bit and may not be that pleasing to the ear. In that case, chapters are your friend.

0:00 Intro and epic slightly detuned stacked saws (3 voices, 2 oscs per voice)
3:13 Triangle LFO at audio rates (mostly annoying bells)
4:32 Arp with global filter envelope (in loop mode)
8:23 Poly portamento
12:02 Unison detune and sample and hold"

video upload by Perfect Circuit

"We've got something a little different for you this fine Friday!

Some of LA's grooviest musicians, Brandon Coleman and Ronald Bruner, stopped by the Burbank showroom a while back and laid down an impromptu jam session on the Nord Wave 2 & Drum 3P


Watch as these two lay down some of the most fun spontaneous improv we've heard at our shop in quite some time. Check out the linked Signal article above for a look at the long list of accolades these two have under their belts, and keep your eyes out for more...Coleman has a new project emerging soon from Brainfeeder, and no doubt we'll see both his and Bruner's names keep cropping up alongside other amazing and talented artists!

1982 Nuova Elettronica LX-520 Monophonic Analog Synth

video upload by Enzo Boldrini

via this auction

"Rare monophonic analogue synth LX-520, by Nuova Elettronica, made in Italy, in very good conditions."

This appears to be the first one featured on the site. Nuova Elettronica was an Italian DIY electronic magazine publication. You can find a few pics below and a couple of other projects, one of which was another synth, in previous posts here.

New BugBrand Drive VCA & Sequence Modules

Interesting side note: BugBrand is entering their 17th year this year, and so is MATRIXSYNTH. This verson of MATRIXSYNTH that is. The original launched in 97. That aside, the new modules:

via BugBrand

The Drive VCA combines most of the features of the Dual Amplifier module into a single space.

It can either be run in Clean (Cln) mode as a regular VCA or switched to a sweepable mix between Zener-Diode Saturation or harmonic Wave-Folding via the Type control.

Control level is a sum of the Initial (Manual) control combined with the two CV inputs – one has a depth control with polarity & mute switch, while the 2nd is full-range unattenuated.

The response can be swept from Exponential to Linear, altering how the VCA responds to control signals.

The VCA is DC-coupled with gain up to unity.

The Sequence module is a powerful sequencing & clocking module with some interestingly different functions that take it away from regular binary approaches. The core builds around a binary logic counter chip, with clocking, reset & direction input options, while on the eight output steps it offers two gate busses and a voltage output with variable Up/Down glide. The rear of the module features several expansion headers allowing it to tie ‘behind the scenes’ to other clocking modules to create an integrated sequencing system.

Have a check of the block diagram image above. Note that control inputs pass through comparators (threshold c.+1V) so can work with almost any signal.

Clocking – the onboard Clock Oscillator goes from approx 0.65Hz/40BPM up to c.140Hz (8400BPM!). The main clock source is switchable between Internal (Clock Osc) or External source, and can clock fine at audio rates (tested up to 20kHz!).

The Clock Output is switchable between Internal or Main – allowing you to send out the Clock Osc & divide it before sending it back in to the External Clocking input (thanks Palle for that suggestion!). The Main option for this switch can also be changed to output the Lengthened clock pulse via a rear header (MAIN_CLK_OUT) which is set to CLK as standard.

SUPERBOOTH22 Makes Adjustments for Ukraine Refugees


We hereby inform you about the revised room plan for SUPERBOOTH22 & SOOPERgrail – BeSOOPER. Parts of the FEZ-Berlin are in the potential control of the city of Berlin as an emergency residence for refugees from Ukraine. Out of consideration for this circumstance, we have partially rearranged our event. Please find all details in the attached press release. Thank you.

Press release follows:

„We have revised our space concept for beSOOPER and discovered the Badesee (Bathing Lake), now there is even more air and space for sound and visions of new music.“

Parts of FEZ-Berlin are in the potential access of the city as emergency accommoda- tion for refugees from Ukraine - which is of course appropriate and important. Against this background, it has been decided to develop further areas in the park grounds, to do without the use of the West Wing and to divide the Seebühne (Sea-side Stage) bet- ween two new locations. All artists announced for the Seebühne will be presented on the beach stage at the Badesee (Bathing Lake) and the new stage in the circus tent.

beSOOPER will thus be even bigger, with even more space and activities both outdoors and indoors: more than 150 booths with all kinds of electronic musical instruments and guitars of all known and unknown types, about twenty performances, concerts, presen- tations and workshops per day, including some late-night activities in the Bungalowdorf (Bungalow Village).

The daily cultural program will start at the latest with the workshop presentation of the
SOOPERGrail Modular Synthesizer Ensemble at 1:30 pm and will continue outdoors at full intensity and
volume until at least 10 pm.

Most of the booths and activities for guitar enthusiasts are concentrated on the upper floor of FEZ-Berlin, while the SOOPERgrail concerts will take place in the circus tent. Many of the countless synthesizer and modular manufacturers can be found and expe- rienced in the now expanded tent village - as already very successfully realized in 2021. The well-known and popular catering partners for food and drinks can be found at all outdoor locations.

In the foyer of the FEZ-Berlin there is the general info desk again, as well as the familiar ticket entrance for all visitors and artists, exhibitors and press partners. Guests arriving by public transport via the S-Bahn station Wuhlheide can get their wristband already at the bungalow village, upon presentation of their digital or printed ticket.
SUPERBOOTH22 // 12.-14. May 22:
One-day Ticket 35 EUR, discounted 25 EUR (THU, FRI, SAT)
Three-day Ticket 90 EUR, discounted 70 EUR (THU, FRI & SAT)

SOOPERgrail // 13. Und 14. May 2022:
One-day Ticket 18 EUR, discounted 15 EUR (FRI or SAT)
Two-day Ticket 30 EUR, discounted 25 EUR (FRI & SAT)

• The aforementioned discounts apply to the unemployed, students, pupils, physically or mentally impaired upon presentation of the appropriate proof at the entrance to the event.
• Until further notice, access is subject to compliance with the usual Corona rules, it is as sumed that there will also be a mask requirement on the premises. In case of non-compli ance, we reserve the right to expel guests from the premises without refunding the ticket price after issuing an appropriate warning.
• All tickets will be personal and subject to compliance with the applicable regulations.
• Until further notice, tickets will only be sold in advance and online.
• In the event of a pandemic-related postponement or necessary cancellation of the event,
tickets will remain valid until the last planned alternative date in September 2023.

The war of aggression on Ukraine leaves us speechless.

We sympathize and stand in solidarity with the suffering and struggling people in Ukraine and with the refugees who are being forced to leave their homes.

Our donation goes to CADUS e.V. which helps war refugees in Ukraine and worldwide. We would like to thank all those who do the same, if possible!

Random Sequence Lengths

video upload by boxoftextures

Follow-up to this post.

"So I was minding my business the other day and checking out, as one does, and came across a post about a video from OZ Hall. He had patched up a Eurorack version of a 960 sequencer so it would vary the sequence lengths. I hadn't even watched the video yet but just from what was in the description I was able to see the whole setup laid out before my eyes. I could make this work in Voltage Modular with randomized sequence lengths picked automatically each time through the sequence. So I set to work and an hour late I had this patch, and in this video I go through it step by step to show how it all works.

The major difference between my version and what OZ Hall did is that I added a Random Task module and a couple of switcher modules so it could switch sequence length on its own without me having to manually do it. Could totally be done in hardware given the proper modules, of course.

To make this work what I've done is to connect each sequencer step's trigger output jack to an input on a switching module. Then, every time the sequencer hits step 1 it sends a clock to the Random Task module, which makes it pick a random voltage. That gets sent to the 1x8 Switch module which picks the output based on the voltage level. That voltage gets sent to the switching module which sends a voltage for the chosen step into the buss module and then on to the trigger input of the sequencer, forcing it to start over from step 1.

So every time the sequencer hits step 1 it essentially picks the step which triggers the reset to step 1 and you get random sequence lengths, picked by the Random Task.

So I'd like to thank both Matrix and OZ Hall, and there are links below to both the post on and to the YouTube video that set all the bells off in my head.

From Cherry Audio
960 Sequential Controller
962 Sequential Switch
Random Task
1x8 Switch
Mini LFO
Stereo Delay

From Andrew Macaulay
Micro MixBus
Fixed DC

From Playertron

From haslo

Lastly, just to make this super clear as I don't explicitly bring it up in the video, say you want to have a four step sequence. In that case, you'd want to patch the output jack of step 5 to the input jack of step one, What we're doing with the switching mechanism is having *all* the output jacks connected at once through the buss but we're letting the Random Task module choose which switch it closes on the switching module to let one of those signals through. So in a sense we're using a module to repatch the bottom row of jacks on the sequencer on the fly.

GRP R24 Sequencer - Performance Rig #shorts

video upload by O.Z. Hall

"This is a demo of the R24 sequencer. I wanted a portable sequencing solution that was fun to play. I mounted the GRP R24 sequencer in a QCP22 Portable Cabinet. I have a number of modules, including the new Q169 and Q168 Oscillator++ Combo, providing oscillator/env/amp as well as raw noise. I've also got two Z506 Swiss Daisy DSP modules, a well as bandpass filter, VCA, mixers, etc.

There are 4 voices total. Here are the voices in order of 'introduction':
1) Z506 Swiss Daisy DSP in voice/delay mode. CV/Gate from R24 Row 1.
2) The Q169 oscillator 1 processed through the Swiss Daisy DSP for VCF/VCA/ADSR. CV/Gate from R24 Row 2.
3) The Q169 oscillator 2 set to a noise waveform and processed through the Q169 VCA 2/AD envelope. Gate from R24 Row 2.
4) The noise from the Q168 is processed through a VCA/ADSR. The timbre is modulated by a multimode filter (mostly bandpass). Filter CV/Gate from R24 Row 3.

I hope you enjoy watching this as much as I enjoyed making the video!"

"get the pack here-
Check out Jessie's band here

This was a fun pack to make! A friend of mine named Jessie, who's in a band called Sugarskull Piledriver/Choosy Moms, has been playing the saw for a little while. I requested at one of their gigs that he bring his saw with him, so I could sample it. We went to the basement of the club and got a few quick samples, and I was able to make some pretty crazy sounding Ableton instruments out of it, that range from haunting to plucky. I dont know if you would always think it was the saw as you hear them, but its definitely a unique quality nonetheless. Hope you enjoy it! I've been having fun playing around with them and creating some atmospheric ethereal sounds. This jam was whipped up using only the Ableton Saw instruments and a drum rack."

Moog Source SN 3696 w/ Encore MIDI

via this auction

"To me this sounds better than most late 70s minimoogs Ive used and you can save 256 patches on this! This Source is the one you want and will save you a TON of headache in the future. This source has been serviced in 2021 by the best in the business right now, Rosen Sound, and sounds absolutely fantastic. The fine folks at Rosen sound rebuilt the power supply to help future proof the rest of the components and increase stability. They also installed a new Encore Midi which adds midi sync ability, midi in and out, and expands the memory 16 times the original, these are 325 new plus installation. Please research the encore midi system before purchasing. They also replaced the two light sensors for the control knob with NOS parts and calibrated to factory specs. These all will go and these parts are getting harder to find, like damn near impossible, and very hard to install/calibrate. It took Rosen Sound months to source these parts alone and they probably own the last remaining available for these. This control knob is now ready for another 30 years of use and this synth is impossible to control without it. As it is the membrane works perfectly but it also comes with a spare membrane panel from which is supposed to be the best replace panel available for when the membrane experiences problems in the future (they all go bad eventually). Parts and labor for all of this future proofing on a once very finicky synth was about 1500 dollars. If you buy a different source and want to keep it alive I would expect to pay the same in the near future."

Oberheim OB-X voice boards compared to OP-X PRO-II

video upload by SonicProjects

"Oberheim OB-X voice boards tuning trimpots and the autotune function compared to the tuning features of the SonicProjects OP-X PRO-II software VST AU synthesizer.

This is an addition to the 'Voice management and detuning' chapter in the official Tutorial: [posted here]

For this comparison we are having a look at the electronics under the belt of an Oberheim OB-X Rev. 2 with 6 voice cards installed.

OP-X PRO-II internally works exactly the same as a real voltage controlled polyphonic analog synth including separate independent voices, voice-based tuning trimpots, slightly deviating voices caused by device tolerances and temperature drift, and autotune.

The autotune options in OP-X PRO-II however not only cover pitch (as in OB-X) but also filter cutoff (as in Matrix-12), filter envelopes and portamento, and autotune also can be applied seamlessly on demand, so achieving any state between tuned and detuned.

Other than in real voltage controlled polyphonic analog synths OP-X PRO-II can save the state of detunings with the patch and so allows a different sate of detuning for every patch, which was impossible to do in the originals.

SonicProjects invited this engine already back in 2006 with the first version of OP-X PRO (in fact already its precedessor OP-X had it, but not yet offerig user-accessible trimports - only autotune) and was the first plugin manufaturer in the world offering this feature.

In OP-X PRO-II this detuning engine has was extended and refined with a seamless autotune option and quick calibration features."

Animal Factory Amplification - Three new modules

video upload by John Schussler

"Animal Factory Amplification consistently turns out some of the best distortion modules available. I have, well, all of them.

Today I got a shipment of the three latest modules: two are upgrades of existing models, and one is brand new. At the time of this video's creation the manuals weren't yet available, so I'm having to guess a bit as to functionality. Take my commentary with a grain of salt.

Baron Samedi and Pit Viper have both been reworked as surface mount rather than through hole point-to-point wired PCBs. I tried them side by side, and hear no significant difference between the older and newer modules in terms of the quality of sound.

The newer versions do, however, have some new tricks up their sleeve, which you'll see shortly.

And then there's the entirely new module: Bonesaw, a filter with built in FM and drive so as to properly fit in to the nasty, grimy, tear it up, huge tone sound AFA is famous for.
