In fact, I've been hard at work through the holidays to bring you the best eurorack modules and more. Be sure to check them out in my Reverb Store. Fantastic new modules and content are planned for 2019, so be sure to check back often. Happy New Year!

Behringer Model D Patches #1

Today I am auditioning some original patches on the Behringer Model D Synthesizer.
Patches show the versatility of this intrument.
From basses, arpeggios, percussion, and more.
Recorded Direct to Tascam DR-05.
All auditions are heard dry, no effects.
Selected auditions are then used with the Timefactor Delay.

If you are interested in trying out some of these patches, I made the patch sheets available for download right here on this blog.
Look over on the sidebar where it says Featured Post Download Links, click it!
That will take you to my download page.
That is where I manage the patch downloads for various synthesizers.

Akai S900 Sampler Floppy Disk Drive Cleaning [No Soldering]

Floppy Drive on your S900 not working?
Does it take a while to warm up before the floppy starts working right?

You may be able to bring your disk drive back to life and/or improve its performance with a little cleaning and maintenance. In this video I show how the S900 floppy drive can be removed and cleaned with some simple tips.

Why would anyone want to mess w/ archaic floppy disk drives? While USB drive emulators are available which greatly increase the convenience and storage capacity of sample banks...
For me it's nostalgia. I just like floppies, you can still find boxes of blank floppies at thrift stores and garage sales. I also still use cassette tapes, some vinyl, and still buy CDs as well.

These tips may not guarantee results in every situation. The S950 and other samplers may differ in design/construction. However, these tips may possibly help you with other devices like E-mu, Ensoniq, Kawai, etc.

Beware! If you're not confident or experienced in electronic disassembly or repair, there's no shame in taking your sampler to a qualified technician. Floppy drives are delicate and have easily broken parts and bezels. You MUST unplug your sampler before attempting any service inside. Take all necessary precautions regarding static electricity discharge so as to not damage any sensitive electronics inside.

SH2-VCF Reporting For Duty! Eurorack Filter Module Demo #2

Following up on my prototype demo, the SH2-VCF is finished and reporting for duty. My SH2-VCF is a filter adaptation of the Roland SH-2 analog synthesizer filter using BA6110 op amps in place of the extinct BA662 chips of the original.

In this video I'll keep the talking to a minimum and explain how I resolved the BA6110 issue. And then put the filter through some paces including a massive kick drum, and an example track using TWO of these filters.

Be warned - some huge resonant kick drums ahead!
Audio recorded direct to Tascam DR-05 except the last part which has some delay.

Oberheim Matrix-12 Synthesizer Sounds Demo #10

Today it's snowing a bit early this year. Nothing better than being hunkered down with a lovely Matrix-12 synthesizer. Each of the patches are auditioned dry first, then I maybe activate either/or Timefactor and Big Sky - some patches don't need anything :)

Patches range from the super-dark horrorshow opener, thick airy pads, hyper-surreal soundscapes, the occasional bass, and the occasional Hans Zimmer plucky thing.

Recorded direct to Tascam DR-05, audio was normalized.
No other effects or processing.

SH2-VCF EURORACK PROTOTYPE AND STUDIO UPDATE AUDIO+TALKING

Today I wanted to make sure to update you what's been happening around the studio and my SH2-VCF prototype module. Been busy organizing a big garage sale, re-organinzing the studio, hanging synth shelves, trying to source a 4-foot wood table, and working for about 2 months on my SH-2 filter prototype.

This SH-2 filter came about as I had a few BA6110 chips laying around and wanted to do something with them. First I built the filter on a breadboard and it wasn't working. Turns out 1/2 my new old stock chips were not doing their job for some reason. No biggie, I designed/ordered some pcb/panels and some more BA6110 chips from ebay.

As luck would have it these chips would be the bane of my existence. I ordered some more BA6110 from activeparts and none of those worked. I also adapted my board to accept the different pinouts for some BA662 Open Labs clones...those caught fire. On the forums these clones are highly admired and used in X0XB0X apparently. It's all good, I just wasn't able to get them to work in this circuit.

So until I get this BA6110/662 issue figured out I won't be able to build any more modules to sell. Time to move on to some other projects and, forbid, make any music :)

Be warned - some harsh resonance acid house squealing ahead!

Three 101-VCF Modules Polyphonic Filter Demo 03 (Roland SH-101)

Today I deploy THREE 101-VCF modules for some polyphonic synth music.
The three filters are getting their CVs round-robin much like a polyphonic synthesizer distributes their voices.
To do this I use the sequential switch to rotate the firing of envelope contours going to each 101-VCF.

Breaking Down Jupiter-6 Sounds w/ JP6-VCF Eurorack Module Demo 3

Today I'm breaking down some of the sounds from my Jupiter-6 Synthesizer demo Critical Mass.
Time was, I had a real Jupiter-6 but later sold it.
So today I will be showing you how to do these sounds on my JP6-VCF Eurorack module.

Big Bass Stab 0:42

Downtempo Electro w/ JP6-VCF Eurorack Module [Roland Jupiter-6 Filter] Demo 2

For more info on my JP6-VCF

Today I'm doing a little electro jam with my JP6-VCF module.
A bit of a deep house vibe, what I call the poor mans Jupiter-6 trick...
On the M-Audio Venom I've made a filter-bypassed polyphonic sawtooth patch.
The Venom dry output goes into the JP6-VCF.
JP6-VCF gets CV from the 2xADSR, going to the VCA on Bastl Skis.
The 2xADSR gets its trigger from Varigate4.

Arturia Beatstep Pro is providing the Bass Pitch CV + gate.
As well as the master clock for Varigate4.
The bass is the Pittsburgh Synth Box going to 101-VCF module.
101-VCF gets CV from the other channel of Bastl Skis.
And processed by the Skis VCA.

Hats are coming from Basimilus Iteritas Alter.
Also triggered by Varigate4.
At first it is dry, then mixed through my Spring Tank Reverb Driver.
Tank Reverb picks up a CV signal from the other channel of 2xADSR.
To keep it interesting the Tank Reverb out goes to EMW VC Pan module.
Which is having pan modulated by the Pittburgh Toolbox S/H.

Kick sounds mighty fine coming from Future Retro Transient+, no effects.
Going directly to the Mackie mixer, kick muting happens there.

All euro stuff is going through the Timefactor Delay.
Audio recorded direct to Tascam DR-05, no post processing.

JP6-VCF Eurorack Adaptation [Roland Jupiter-6 Filter] Demo 1

This is no emulation, this is the JP6- VCF:
A faithful adaptation of the Roland Jupiter-6 synthesizer filter circuit in a slim, skiff/boat-friendly, 8HP Eurorack format module.
Great care was taken to keep the JP6-VCF fully analog circuit as close to the original as possible including 2 rare OTA filter chips and and thermistor frequency stabilization.

Mode switches are configured to give 4-pole LP, 4-pole HP, and 2-pole BP.
The JP6-VCF wields two audio INPUT jacks with a MIX pot.
Two CV IN jacks w/ signal attenuation pots allow you to modulate frequency with any two polar/bi-polar signals, low Hz up to audio rates.
Every module is hand-assembled and ready to rock your world.

Be warned - some sharp resonance sounds ahead!

CRUMAR PERFORMER: Noise Reduction Mod and Sustain Mod

Today I am looking at a friend's Crumar Performer.
We noticed a considerable hiss noise when activating the String sections.
The hiss goes away when using only Brass.
I investigate where the noise is coming from, and what's to be done about it.
I discover a simple way to boost the strings signal without affecting the noise floor.

Another strange deal, by design, the brass button defeats the strings sustain.
I explore the sustain mod to restore the strings decay while using brass.

DELTA VCF + JUNO-1 (Progressive House) [Fair Weather]

Today I'm performing a Progressive House jam featuring my Delta VCF Eurorack Module.
The Delta VCF is a eurorack adaptation of the Korg Delta/Poly-61 synthesizers, and it's excellent for resonant bass pads!
And with resonance it will not dilute your bass frequencies like some filters do.

101-VCF Filter Higher Pitch Sequence Demo 02 (Roland SH-101)

In my last demo of the 101-VCF 8HP Eurorack module we heard some big phat bass sounds.
So what does higher-pitch sequences sound like going through it?
Answer: Sugary sweet, like a dream.
Take my word for it but watch the video anyway it's a bit repetitious but fun.
Be warned - some delicious high-end pitch resonance ahead!

Introducing My 101-VCF Euroack Adaptation Roland SH-101 Filter

Today I am proud to show you my 101-VCF - my adaptation of the Roland SH-101 lowpass resonant filter in a slim 8HP Eurorack module. A filter described as somewhere between a Juno and a 303. Every effort has been taken to preseve the original analog circuit as much as possible. Be warned - some harsh resonance squealing ahead! Recorded direct via Mackie mixer to Tascam DR-05, no effects or post-processing.

Oberheim Matrix-12 Synthesizer Percussion Demo

OMG that Snare sounds familiar. No drum machines or samplers were used in this demo. No, today you're getting a full dose of Oberheim Matrix-12 percussion sounds. Watch as I corral a group of freshly programmed percussion sounds together using MIDI assignments in multi-mode. The Beatstep Pro is in full trigger control. Muting tracks is done on the M12 channel volume page. Recorded direct to Tascam DR-05 via Mackie mixer. No effects mucking about whatsoever. I should be making the patches available sometime soon. Thanks for watching!

UNIVOX MINIKORG SYNTHESIZER REDUX

Today a follow-up demo of my Uniox Minikorg w/ a Pitch CV + Gate mod controlled by the Arturia Beatstep, this time sans the annoying percussion. This synth is one big continuous sweet spot! Some delay by Timefactor, a touch of Big Sky reverb, recorded directly via Mackie mixer to a Tascam DR-05. Press play, kick back and let it ride.

2xADSR Dual Envelope DIY Project

And here it is...a dual 4-Stage envelope generator 8HP Eurorack. 2xADSR is a dual envelope module in 8HP Eurorack format based on the Arturia Minibrute. The schematics are openly published on the internet, so it would seem reasonable to have adapted a fun DIY panel/pcb project for educational purposes under fair use. Each envelope is an independent Attack-Decay-Sustain-Release linear contour. Each envelope takes a gate input, puts out a positive-voltage contour and a buffered negative-voltage (DC inverted) contour.

This is a DIY project, just a pcb/panel only, with surface-mount soldering required. You supply the parts components (not included), but it uses all very affordable and easy-to-find parts. I would not recommend this as your very first SMT build, maybe your 2nd or 3rd SMT build though. The BOM and Schematics for this project can be found on muffwiggler
PCB/panel are available in my Reverb Store

Testing Univox Minikorg CV+Gate Analog Synthesizer Mod

Testing out a Pitch CV + Gate mod for the Univox Minikorg, AKA Korg 700/700S. The arpeggio gets faster and ends up sounding inspired by Pink Floyd On The Run. The circuit one the breadboard is from E-Labs, Japan as shared by Cykong.com. I added a buffer on the gate since the Beatstep Pro trigger did not push enough current to make it happen. Strangely, the gate does work w/ the original MS-20. Beatstep Pro can do Hz/Volt, this setting can be made in the Arturia Midi Control Center software. Recorded direct to Tascam DR-05, no additional processing. Here's the lowdown:
Synth - Minikorg
Percussion - Basilimus Iteritas Alter
Percussion Trigger - Varigate4
Delay - Timefactor
Reverb - Big Sky, Hall setting

Spring Tank Reverb Eurorack Prototype Module

Today I am showing my prototype Spring Tank Reverb module. It's a driver for old school spring tanks like those found in vintage mixers and guitar amplifiers. The driver module has controls for Drive, Tone brightness and darkness, wet/dry mix, and an input for sending CVs to control the wet/dry mix. I'm using an envelope for CV, Beatstep Pro for trigger sequencing, and beats are coming from the Future Retro Transient. I also run the signal through my dual channel compressor, using a trick where both channels are cascaded for additional compression. I also briefly punch in some delay from Timefactor. Audio was recorded direct to Tascam through a Mackie mixer. EDIT: I noticed some users are connecting this to things that are not eurorack systems. To assist you w/ your efforts here are the active pins on the power input.

Spring Tank Reverb Breadboard Eurorack Demo

Try not to let your heads explode when this sickness fondles your eardrums. Got my hands on an O.C. Electronics Spring Tank Reverb. On the breadboard I've built a driver circuit with voltage control of the wet/dry crossfader. Who does that???!!....

I do that. And today's demo shows you why. The Future Retro Transient+ is going through the spring tank. The mix is set mostly dry, but I'm using a short envelope to send a burst of reverb wet mix when the snare hits. Using the Beatstep Pro for that. That's what I'm talking about. That. Is what it's all about.

How did I do this? I've frankenstein'd a couple of circuits/ideas together to make this happen. At its core is a Tombolas DIY Spring Reverb Circuit w/ EQ and Drive Control to accommodate a wide variety of tanks. It worked very well, but I was not yet satisfied. For the Voltage Control, I've slapped away the final amp mix stage and replaced it w/ the VC Crossfader circuit by Thomas Henry. I dumped his VCA control, that's another project for another day, and to made some minor changes so it would play nice w/ the Tombolas circuit.

My DC571 Dual Compressor for Eurorack is Now Available

My DC571 Dual Compressor for Eurorack is now available in my Reverb Store. To operate the DC571:
1) plug in the audio input and output, making sure some sounds are present
2) set the switch up (compress) to activate the effect
3) turn the input knob until you hear clicks/pops (clipping) and then back it down a little
4) set the switch down (bypass) to compare the volume of the original signal
5) set the switch back up and turn the output make-up gain knob until the volume is the same as when you started. You may need to repeat steps 4 & 5, and it’s definitely ok to increase the output a little bit more if so desired! For even more compression, the channels can be cascaded in series. Do this by patching the output of channel 1 into the input of channel 2.

RM&S Ring Mod + Sub-Octave Generator now available

My Ring Modulation + Sub-Octave Generator module is now available at Reverb dot com!

RM&S is a 4HP Ring Modulator and Sub-Octave generator. The Ring Modulator is an active, CMOS-based circuit adapted from the ARP Odyssey. Ring Mod is usually generated from inserting square wave VCOs to Input 1 & 2. But that shouldn't stop you from sending sawtooth, wavetables and noise sources through this.

The Sub-Octave Generator circuit is derived from the Roland SH-101 and provides -1 and -2 octaves from a square wave plugged into Input 1. Many VCOs put out varying degrees of signal amplitude, a trim pot is provided to adjust input impedance of VCOs for the Sub-Octave Generator circuit.

Output jacks include: Ring Mod, summed Ring Mod + Sub-1, Sub-1, and Sub-2. The RM&S is hand-crafted in the USA.

Measured Current Draw: 2mA on -12V, 5mA on +12V, 5V not used

Three Machines = MS-20 + Juno-1 + Eurorack Synthesizers

Feelin' a good 100-bpm chill vibe today. Three Machines are: Korg MS-20, Roland Alpha Juno-1, and the Eurorack system. Future Retro Transient+ is swinging a nice CR-78 groove thanks to mapping some CVs from the Beatstep Pro, running through the Delta VCF to take the edge off the highs. The CEM3340 VCO doing the arpeggio thing using quantization from Ornament & Crime, running through the Tonus VCF. Euclidian triggers from Temps Utile. Bass from the Synthesizer Box. Playing a delightfully mindless riff on the MS-20. Some Timefactor Delay, some Big Sky Reverb. Recorded in one shot, some post-work done in Cubase.

Future Retro Transient+ Eurorack Demo 01

I just got my Transient module back from Future Retro, they have upgraded it to the Transient Plus! The turnaround on this was super-fast! I made a Linndrum-based instrument w/ kick/stick/hihat w/ some modulations including pitch changes. This demo also uses Basimilus and Hats909 as well. Enjoy.

RM&S Ring Mod & Sub-Octave Generator Eurorack

Square waves and Pulse Width Modulation are among my favorite synth things. However, CMOS Ring Mod to me is like PWM on steroids. Today I am demonstrating my prototype module RM&S. It takes two square wave inputs and derives CMOS Ring Modulation based on the ARP Odyssey. Square wave Input 1 is used to generate -1 and -2 octave Sub-Oscillators. But this module has another trick up its sleeve. An additional output is provided which sums both Sub-1 and the Ring Modulation for a super-fat synth tone!

DC571 Dual Channel Audio Compressor Eurorack Prototype

Headphones or quality audio monitors recommended. In this video I demonstrate a prototype of my new DC571 Analog Dual Channel Eurorack Audio Compressor. It will make your bass lines a little punchier, and your percussion grooves a bit more groovy. The way to operate it is simple - the stronger the input signal, the more it compresses. Use the output make-up gain knob to bring the level back up. Both channels are completely independent of one another - so use it for stereo purposes or for two different instruments if you desire. These will be hand-crafted in limited quantities for sale soon, it will have a black front panel w/ white silkscreen lettering. More details on price and availability to be announced later.

Testing A Ring Mod + Sub-Oscillator Circuit

In these quick videos I am testing a DIY Ring Mod + Sub Oscillator circuit through my Tonus VCF (ARP 2600 clone of the 4012 filter). The first video is through a Timefactor Delay. The second video I am punching into freeze mode on the Strymon Big Sky for a colossal wall of sound! The Ring Mod + Sub will become a eurorack module, I will give more info on that soon. Sequenced on Arturia Beatstep Pro. Thanks for watching!

Analog Audio Compressor - 1 Minute Demo w/ Eurorack

Today I am testing out an analog audio compressor circuit on the breadboard with a nice percussion groove from Basimilus Iteritas Alter. This analog compressor will eventually become my next Eurorack module. More to be announced when design is finished.
Today's signal path is dead simple:
Basimilus / Delta VCF / Big Sky (Hall Reverb) / Compressor / Out
Clock and Trigger:
Beatstep Pro / Varigate 4 / Basimilus

Artwork ft Oberheim Matrix-12 + Eurorack Synthesizers

Oberheim Matrix-12 synthesizer + Eurorack = match made in heaven. Glitch beats + melodic pads/strings. Everything performed live, recorded on-the-fly. Reverb on Matrix-12: Strymon Big Sky. Delay: Eventide Timefactor. Some post-processing including compression + eq.

Euro modules: CEM3340 VCO going through my Jupiter-6 VCF module - bass, Noise Engineering Basimilus Iteritas Alter - Kick/Snare, Pittsburgh Modular DNA Symbiotic Waves going through my Tonus VCF - other percussion, Tiptop Hats909 - closed hat, G-Storm Infusor - percussion sub-mixer, Mutable Instruments Clouds - percussion granular mangling, Malekko Varigate4 - percussion triggers.

G-Storm Jupiter-6 VCF vs. Jove vs. SE 8106 modules

I get asked quite a bit what makes the Jupiter-6 VCF different from modules like the Jove by System-80, and the the Studio Electronics 8106. The Jove and 8106 circuits are a similar topology using readily available OTA chips, their PCBs are mass-produced, their boards are probably automated assembly for SMT parts. Mine uses the expensive/rare/original Roland OTAs, my PCBs are currently copper etched and tinned by hand, and fully assembled by hand as well. I'd love to build a Jove for myself, alas - no time (and PCBs are currently sold out). The demos of the Jove sound nice. I haven't checked out any demos of the 8106 yet, but everything SE makes is fantastic. I also suppose this is as good a time to announce my Jupiter-6 VCF is also undergoing a front panel re-design and will be very similar to my Delta VCF version 2.

My Delta VCF Version 2 is Here!

My first video of 2018, I know it's been a while. I have been busy working on this little beauty! Today I introduce my Delta VCF version #2. You will remember the Delta VCF is my fully analog filter adaptation of the Korg Delta/Poly-61 synthesizers with the addition of a 2-Pole mode. My version #2 is exactly the same sound, functionality, and circuit as the version #1. It has a revised panel layout that makes the trimmers available from the front, is 12HP, and is now skiff-friendly. While we're at it, I audition some sound examples - starting with some PWM bass sweeps. I have trimmed the resonance for the module I am showing today so that it could self-resonate, I modulate that with an LFO. Audio recorded direct to Tascam DR-05, no effects or EQ added.
