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.

Pittsburgh Synth Box - 101-VCF #1
DNA Symbiotic Waves - 101-VCF #2
Rozendall CEM3340 VCO - 101-VCF #3
Bass - Behringer Model D
Pads - Roland Juno-1
Envelope Contours - 2xADSR dual envelope
Sequencing - Arturia Beatstep Pro Pitch CV and clock
Kick - Future Retro Transient
Hats - Tiptop Hats909
Additional percussion - Roland TR-606
Delay - Timefactor
Small amount of Reverb - Strymon Big Sky

Recorded live in one shot.
Some post-processing in Cubase 7.

[Roland 909 Day Demo] Juno-1 / TR-8 / RE-20 / 101-VCF / JP6-VCF


Today a special setup for 909 Day!
Featuring some classic Roland circuits.
The highly underrated Alpha Juno-1 on pads and leads.
Getting a dose of cloudy reverb from Strymon Big Sky.
A TR-8 deploying the 909 kit in floor-thumping action.
Smashed to extra crunchy bits in the DBX 166A compressor/limiter.
My RE-20 Space Echo pedal on delay.
The 101-VCF has its input overdriven by Pittsburgh Synthesizer Box.
And the Rozendal CEM3340 VCO going into the JP6-VCF.
Having its resonant arse kicked around my Spring Tank Reverb.
Beatstep Pro on sequencing duty.


Some audio post-processing in Cubase 7.

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
Bandpass Meyhem 2:52
Note: in the video I use high pass mode but still good results.
Bass Pad 3:45
Note Flurry 4:44
Arpeggio Phrase 5:32

More info on my modules
JP6-VCF
2xADSR Dual Envelope

Modules: Bastl Skis, Pittsburgh Synthesizer Box and DNA Symbiotic Waves
Other Gear: Strymon Big Sky, Eventide Time Factor, Arturia Beatstep Pro

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.

EDIT: I posted a video how I produced the chords on my Venom HERE.

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!

Oscillators - Pittsburgh Synth Box, Timo Rozendal CEM3340 VCO
Envelope Contours - Bastl Skis
Other Modulation - Pittburgh Toolbox S/H
Sequencing - Arturia Beatstep Pro Pitch CV + gate

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.
Click for more information on the Delta VCF
Delta VCF is conjuring up a Max Graham style bass pad using waveforms by the Pittsburgh Synthesizer Box PWM and Saw.
Stereo Widening using Eventide Timefactor

Synth Lead - Roland Juno-1, Big Sky reverb
Kick/Snare - Basimilus Iteritas Alter
Reverb-y Snare - Noise into Bastl Skis for a noise burst...
then my Reverb Tank Driver, then uBurst (MI Clouds)
Hats - Tiptop Hats909
Cowbell - Future Retro Transient
Sequencing - Arturia Beatstep Pro

Recorded direct to Tascam DR-05, some post processing in Cubase.

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!

Oscillators - Pittsburgh Synth Box PWM + Saw, CEM3340 VCO Saw
Envelope Contours - 2xADSR dual envelope
Sequencing - Arturia Beatstep Pro Pitch CV + gate
Kick - Noise Engineering Basimilus Iteritas Alter
Hats - Tiptop Hats909
Delay - Timefactor
Small amount of Reverb - Strymon Big Sky

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.

Oscillators - Pittsburgh Synth Box Square, PWM, Sub Envelope Contours - 2xADSR dual envelope, Bastl Skis Sequencing - Arturia Beatstep Pro Pitch CV + gate
