GSE 4023-VCF Filter Demo #3 Saturated Drums

In a previous video I showed how the 4023-VCF has some lovely saturation with synthesizer sounds.
Today I will be running some percussion though the filter. In most cases, when the input slider is above 60% the filter input will start to become overdriven. Resulting in a warm and fuzzy distortion.
I'll be using control voltages to use the saturated filter as a gate,which can change-up the grooves.

Audio recorded direct to Tascam DR-05.
No additional effects other than what you see.

SH2-VCF Temporarily Unavailable

I have pulled the SH2-VCF to resolve a known bug w/ the resonance section. It was very important to me to make the module as close to the same circuit as the original. However, adapting circuits to eurorack isn't always simple. Most likely, because of the difference in operating voltages. If all goes well, the resonance response will be much better in the end. Stay tuned, the SH2-VCF will be returning.

GSE 4023-VCF Demo #2 Lovely Saturation

Darkwave, deep house, tribal and Carpenter-esque sounds ahead.
Of the filters I'm offering, 4023-VCF has the most lovely saturation to me.
In most cases, when the input slider is above 60% the filter input will start to become overdriven.
Resulting in a warm and fuzzy distortion.
Audio recorded direct to Tascam DR-05.
Some use of the Timefactor Delay and Big Sky Reverb.

SH2-VCF Eurorack Filter Module Demo #3

Today I demo my SH2-VCF with more basslines, melodic leads, and a few arpeggios.
I'll keep the talking to a minimum, but explain how I'm setting up the sounds in general.
Audio recorded direct to Tascam DR-05.
I've kept the Timefactor Delay and Big Sky Reverb to a bare minimum.
But you'll hear them from time to time.

Behringer VC340 Vocoder USER REVIEW Synthesizer

Today I am giving a user review of the new Behringer VC340.
The VC340 is billed as a complete reproduction of the Roland VP-330 all-analog circuitry.
I have some experience having owned an original VP-330 MK1.
And previously reviewed the Roland Boutique VP-03 which had an Achilles heel IMHO.
How does the VC340 measure up?

Roland Juno-106 w/ Gravitational Slingshot Chips Overview + Demo

Today I got a special package from Syntaur, the USA distributor of Analogue Renaissance products. It's a set of six 80017A-GS VCF/VCA replacement upgrade chips for the Roland Juno-106 synthesizer. What's involved to install them? How do they sound? I'll demonstrate - but you be the judge!

0:00 Talking
- What are the Gravitational Slingshots?
- What I did to prepare for installation.
- A word on testing/calibration: it's absolutely required
- A minor caveat about my particular synth.

Roland Juno-106 + Eurorack DEMO [Tesla Coil]

The Juno-106 has landed once again in the studio. I put together a little sequence on the BSP. And a warm saturation bassline in Eurorack.

Juno-106 | Timefactor | Big Sky: Arpeggio and swells
2xADSR | 4023 VCF (self resonance): Kick
Synth Box | JP6-VCF | 2xVCA | 106 Chorus module: bass line
Transistor-82 | Spring Tank Reverb | EMW VC Pan: Percussion
Modulations/Triggers: Batumi, Varigate4

Recorded live in 1 shot to Tascam DR-05
Some post processing in Cubase 7.

Announcing 4023 VCF - an ARP Odyssey MK-I Filter Eurorack Adaptation

Here it is - the mystery module presented yesterday at the Dallas Synth Party.

The 4023 VCF is a no-compromises Eurorack filter adaptation of the MKI ARP Odyssey synthesizers that boasted the colorful 4023 module. Slim. 8HP. Elegant beauty. Don’t be fooled by this early 2-pole 70s design, it retains bass power at higher resonance very well, and can self-oscillate with a robust sine wave when you top out the Resonance.

This 4023 VCF adaptation as close to the original as possible including Rochester re-issue CA3080 OTAs struck from the Intersil masks, matched discrete TO-92 transistors, 2N5459 FETs, a temperature compensation resistor for frequency stability, and six 20mm Alpha slide potentiometers inspired by look of the original. Per usual, when the input sliders are above 75% it will overdrive the filter input for some lovely saturation. 4023 VCF has the classic ARP vibe you’re seeking in spades.

Transistor-82 Lo-Fi Analog Percussion Synthesizer Overview Demo #1

Today I am proud to introduce my Transistor-82:
a low tech analog percussion synthesizer Eurorack module.
It's been in the works over a year.
Circuit testing has been well...quite addictive!
First I explain the concept of Transistor-82 and how it came about.
Then take a quick tour of the front panel features/controls.
And close out with some audio demos.
