Alfa AS3109 VS IR3109N Quick Comparison

Many have commented about my last video why I fool around w/ reclaiming the old chips when Alfa has some remakes on the market. So here's a quick comparison of the Alfa AS3109 remakes vs. IR3109N OTA chips in my 101-VCF tester module. For me the Alfa behaves quite differently with regard to signal clipping and output magnitude. Enough as to not recommend them as a 1-to-1 replacement in vintage synths and the reason I don't use them in my own modules. It's too bad, I enjoy using other kinds of Alfa chips 3320/3340/3350 in other filters and my 101-VCO.

Granular Synthesis - Pulse Synthesizers Load Runner Module Demo

Today I am checking out the Load Runner Granular Synthesizer Module by Pulse Synthesizers.
Back in 2018, Youtube user John Crombie was uploading these prototype videos of a sampler in development.
It started out life as a 4-channel sampler
And evolved into the granular processor we now know
How does it differ from Mutable Clouds, Akai S612, and Erica Sample Drum?
Let's take it for a spin and see how it sounds.

Recorded direct, no other mastering or effects.

G-Storm Electro Patches for Roland Jupiter-6 [Demo #4]

Auditioning some original Roland Jupiter-6 patches available for download. I had the good fortune of getting another Jupe in the studio. The previous one that had Europa was sold. This one is an earlier model, and was purchased dead. After bringing it back to life and calibration... Soon I had quickly re-programmed all my favorite sounds.

This video is un-rehearsed, so lots of noodling. Not dwelling too long on any one sound, to save your time. So if you skip around, you might miss something. Just sayin' :D Chord stabs, sweeps, bass, apreggio, sound fx, leads. Patch F7 is my template (default, or blank) patch. Patch F8 is my scratch patch, for when I can't remember what location I wanted to over-write.

The Roland Jupiter-6 has only rudimentary midi capability: simple note on/off and patch change midi message only. So, these patches can only be dumped all at once using the cassette interface. BE SURE TO BACK UP YOUR OWN PATCHES BEFORE OVER-WRITING THEM!

Download the patches as an mp3 audio file on my DOWNLOAD PAGE. I have used the JP-6 VERIFY function and confirm the audio file is good.

No additional effects or processing was used, aside from some normalization. Video was made in great haste - so it's un-edited, some audio levels are clipping. And sometimes scratchy volume pot.

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!

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.

Jupiter-6 VCF Eurorack Filter In-Depth Demo Roland Clone

In this video I do a more in-depth demo with my Jupiter-6 VCF multi-mode filter clone eurorack module. It's a very colorful filter that gets more interesting with more complex signals you feed into it. It also has an aggressive nature that comes out when the inputs are overdriven.

Two different oscillators can then be mixed together. A sawtooth oscillator is used, a square/PWM wave is used. Different filter modes can be selected: 4-pole lowpass, 2-pole bandpass, 4-pole highpass. Also, two different control voltage modulations can be mixed together to change the frequency. I run a decay envelope from the Bastl Skis along with a triangle LFO, then I use Sample-and-hold. The oscillators are coming from my Pittsburgh Modular Synthesizer Box. Recorded direct to Tascam DR-05 from my Mackie mixer, no effects, no normalization. Beware some low and high frequencies, so watch your levels while listening to the demo.

More information about this module can be found at https://www.modulargrid.net/e/other-unknown-jupiter-6-vcf

Basimilus x Disting x Juno-1 x Synth Box x JV-2080

In this video the Eurorack is patched for a noir future tech workout. Think Blade Runner meets Air Liquide meets Blue Room Project. Basimilus and Disting team up for filthy glitch beat detail under command of the Varigate 4. Then darkened up by the JP-6 VCF. Disting is loaded w/ TR-606 sounds, but mangled by pitch modulation. Bastl Little Nerd is spitting out gates in all directions. Pittsburgh Modular Synthbox simmers a nice PWM bass pad. Ere there be JV-2080 Mellotron Choir getting the chop-chop from Bastl Skis. Soaring leads and swells are the Juno-1, my Aurora Pad 1 patch. Timefactor Delay on the Juno-1. Mixed on a Mackie 802-VLZ3, recorded direct to Tascam DR-05.

Eurorack Synthesizer ft. Mutable Rings Roland TR-8 [Barricade]

In this video I'm having a go with Mutable Instruments Rings with the Roland TR-8. Rings is getting signal from Synth Box, V/Oct from Beatstep Pro and going through Timefactor Delay. DRUMS. Okay the TR-8 is getting Big Sky Reverb and gated by the Bastl Skis, rhythmic trigger by Bastl Little Nerd. I'm really liking these Bastl modules! No, really. Bass sounds a little funky. The DNA is feeding the JP-6 VCF but gets lost underneath the percussion. So, yeah there's no mastering or EQ here. Recorded direct to Tascam DR-5.

Evolving Chords Eurorack Synthesizer Performance Demo

Performance using evolving chord changes with my custom DRE4MTR4CK Euro module. It has 4 independent tracks of polyphonic pitch control:
Track 1: Pittsburgh Synth Box, internal filter
Track 2: DNA Symbiotic Waves, JP-6 Filter clone
Track 3: Disting MK3, Doepfer SEM filter
Track 4: Rings, no filter.

Clocking direct to envelopes, triggering pitch changes manually. Track 1 pitch CV is going through a PM Toolbox slew limiter. Mix is going to Timefactor delay. Recorded direct through a Mackie 802 to a Tascam DR-05.

Roland Jupiter-6 Synthesizer Filter VCF Build - Demo 01

This video demos a Roland Jupiter-6 synthesizer clone filter VCF. This breadboard build took two days, and for me is the largest one I've built yet. Does this circuit sound as good as the original? You be the judge. Anyway, I really wanted to hear what it sounded like before deciding about building my own module.

I came across schematics for the Roland Jupiter-6 at amsynths.co.uk. They actually sell completed modules and PCBs, however they seem to be perpetually out of stock. This will be a nice companion multi-mode filter to go next to my SEM module. IMHO the SEM sounds buttery and creamy, and the Jupiter-6 is a complete savage with outrageous low end.

The details: The sound source is the Pittsburgh Modular Synthesizer Box. I like to use a pulse wave w/ variable pulse controlled by LFO. The Synth Box filter is wide open, its envelope is passed to the JP-6 CV input #1. I don't have switches hooked up to the filter modes, so I'm pulling/resetting jumpers on the breadboard to achieve that. In this video I also crank the VCO to overdrive the pre-filter INPUT on the filter clone. I don't think you can do this on the original Jupiter-6, but you CAN push the post-filter VCA level into distortion much of the time.
