Introducing the JP4 Chorus - Dual BBD Ensemble for Eurorack

Introducing my JP4 Chorus: a eurorack adaptation of the Roland Jupiter-4 Ensemble effect.
Using dual bucket brigade delay lines.
Headphones recommended :D
Check my Reverb store for module availability http://reverb.com/shop/gstormelectro

In this video I will be auditioning basic waveforms from my 101-VCO thru the JP4 Chorus.
Then adding some reverb from FX aid.
Roland Juno-1 basic sawtooth patch thru the JP4 Chorus with the help of a homemade preamp.
Note: while the JP4 Chorus is designed primarily for eurorack signals, you will want an instrument/line preamp module for use w/ external gear like guitars and synthesizers.

Feedback 106 Chorus Demo DIY SMD Version X-Vive Eurorack

Here it is. My fully assembled 106 Chorus by Feedback electronics.
I am not affiliated w/ Feedback or this project.
Just here to give a demo.
And to give some 'feedback' from my build of the surface mount version.

How difficult is the SMD version to build from a bare circuit board?
What are some pitfalls on this build?
How does it sound with the re-issue X-Vive chips?

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

[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.

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

Reverb-y Snare - Noise into Bastl Skis for a noise burst...

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.

Eurorack + Juno-1 + MS-20 "Harp-y"

Downtempo Lo-Fi track I threw together today. Juno-1 'Harp-y' patch, MS-20 bass, Eurorack for all else.

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.

Acid Tech House MS-20 Juno-1 Eurorack Modular [Heavy Duty]

In this video I jam the MS-20 going through the DBX 160A on kick, Juno-1 on synth sequence and eurorack modular for all else. That kick! I tweak the MS-20 release time for those massive booms and Env2 to LP amount for more crunch. I'm pretty happy w/ those hats too - hats were synthesized using DNA Symbiotic Waves and Deflector Shield Ring Mod. The cracking snare is coming from a Disting sample of the Linndrum clap, with the initial transient clipped off. Bass is a square wave from the Synth Box going through the JP-6 VCF module. Juno-1 uses the classic factory patch 1-1 PolySynth1, has some Timefactor delay. Beatstep Pro sequences the kick, bass + synth. Varigate 4 + sequential switch + Little Nerd gates other percussion. Mixed on a Mackie 802-VLZ recorded direct to Tascam DR-5.

Ibanez Bi-Mode Chorus Pedal Demo w/ Synthesizers #9 [Roland Juno-1]

In this video I demonstrate the Ibanez Bi-Mode Chorus with a Roland Alpha Juno-1 synthesizer. This is a vintage analog chorus from the 80s that uses Panasonic BBD Chips. It has only one chorus line like most pedals. However it is modulated by two LFOs w/ corresponding width (amount) knobs on each! How does it sound with a synthesizer? You be the judge.

Roland Alpha Juno-1 Synthesizer Demo #2 New Patches

Rolling out some new patches for the Juno-1/2 available on my download post for this blog. A full bank of patches including the sounds from Demo #1. In this video I have selected a few of my personal favorites: bass, arpeggios, and soundscapes/pads. There are copious amounts of Big Sky reverb, a couple of sounds use the Timefactor delay. Basses don't usually need anything. Sounds were programmed using the indispensable Stereoping synth controller, also used briefly in this demo. Recorded direct through a Mackie 802-VLZ mixer to a Tascam DR-05.

Intro to Creative Mid-Side Audio Processing in Eurorack Modular

What is Mid-Side Processing? How can you use Mid-Side in your Eurorack musical endeavors? In this video I'll show you how. Using the Worng LRMSMSLR module I provide some interesting patch examples of Mid-Side in action.

HEADPHONES OR A SET OF QUALITY AUDIO MONITORS ARE REQUIRED to hear the full effect of Mid-Side processing of stereo audio. My sound source today is a Roland Alpha Juno-1 w/ the chorus turned on. Remember, if the chorus is turned off, the synth only provides a monaural signal which is no bueno for Mid-Side processing. The Roland VP-03 Boutique Vocoder also provides an interesting ensemble choir sound that is useful.

Audio was recorded direct to Tascam DR-05 through a Mackie Mixer. No other effects were added to the sound other than the modules explained in this demo.

Other modules used in this video:
- Pittsburgh Synthesizer Box, MIDI3 module (clock)
- Pittsburgh Mix Mult (attenuators), Toolbox (S&H), Outs
- 4MS Rotating Clock Divider RCD
- Doepfer A-106-5 SEM Filter
