You know them, but what are some of the sonic differences?
Watch out, some skreechy resonance ahead. They're filters after all :D

Cascading Two Filters Tips/Tricks Delta VCF Eurorack Synth [Demo #4]

Today we've got a good one.
I'm going to show you some fun to be had running two filters in series and parallel.
You can do these things with any filters w/ lowpass and bandpass.
This time using two of my Delta VCF modules.

0:00 Opening
0:38 Cascading Filters (2 Filters in Series)
4:20 Parallel Filters

The Delta VCF is an adaptation of the Korg Delta/Poly-61 filter.
Per usual, my sound source will be the Pittsburgh Synthesizer Box.
LFOs are coming from Batumi.

Audio recorded direct to Tascam DR-05.
Some normalization, otherwise no effects.

The Wild Side of the Delta VCF 8HP Eurorack Synth Demo #3

This is my Delta VCF 8HP analog filter module.
It's an adaptation of the Korg Delta/Poly-61 filter.
The Delta VCF 8HP is exactly the same circuit as my previous versions.
Today I'm patching into the wilder side of this filter.
I bumped the resonance trimpot a bit for this one.
So be warned, there's a bit of wonderful resonant squaling ahead.
There's a variety of sound sources and CV modulations being fed in.

Arturia Drumbrute Impact, Pittsburgh Synthesizer Box, Synthesis Technology E352 Cloud Terrarium, CEM3340 VCO, Batumi, 2xVCA, 2xADSR, Basimilus Iteritas Alter, Varigate4, Temps Utile.

Audio recorded direct to Tascam DR-05, no effects.

101-VCF Red + Delta VCF 8HP Eurorack Modules

I am proud to introduce two Eurorack modules. The first is my 101-VCF now available in Red panel, and it looks as stunning as it sounds. And the other...the Delta VCF is back! Now in 8HP, draped in a space-age white aluminum panel.
Available exclusively in my Reverb Store.

Update from the Studio/Lab January 2019

January is normally D-E-D....dead. So slow. Not this year! So much happening: modules are getting sold out, a couple of great modules getting makeovers, and recently released a new and awesome module - but totally slipped under your radar. Shame on you, starting with that one then...

If you haven't seen it yet, be sure to check out my 6HP 2xVCA dual VCA in my Reverb store. It uses BA6110 chips just like those used in my amazing SH2-VCF filter. So many fun tricks to do w/ that one - I'll have to make a video of those things soon so keep an eye out for that one.

The Tonus VCF is sold out at the moment, as it very well should be - it's the MK1 infringement filter virtually plucked from an ARP 2600. I should have more of those ready to go very soon, just been a little tricky to keep up with the demand.

Lastly. TWO awesome things are getting a killer makeover and should be hitting the road in a week or two. The first is my 101-VCF coming soon in a RED Panel. It looks every bit as tough as the original synth. The other is my 8HP Delta VCF coming in a space-age White panel. Not to worry, I'm keeping those funky green LED sliders for extra vibe.

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.

Delta VCF is conjuring up a Max Graham style bass pad using waveforms by the Pittsburgh Synthesizer Box PWM and Saw.

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)

Cowbell - Future Retro Transient

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.

Happy Holidays from the studio

Quick update. Just added a couple more units of my Tonus VCF euro module adaptation of the ARP 2600 filter (4012 module) to my Reverb Store. They are now having the waterjet cut panels.

My Delta VCF module is sold out currently, I am taking this opportunity to re-visit the panel layout. I would like the jacks to be all at the bottom of the module like on the Tonus VCF. Using surface mount would make the builds go quicker as well. Hoping the Delta VCF will be available again before the year is out, we'll see. There will be a more official announcement and panel render when time comes.

Delta VCF Eurorack Filter Module Korg Clone Demo (Poly-61)

The Delta VCF is my faithful eurorack clone of the Korg Delta synthesizer filter. The lowpass filter circuit was also found in the Poly-61. In this video I demonstrate the features and sound of the filter by running various signals, control voltages, and sequencing through it.

Features: Illuminated Frequency and Resonance Slider pots. Mix together two different input oscillators at the input jacks w/ signal attenuation/gain pots. These inputs can overdrive the filter. Modulate the filter cutoff with two different input control voltages w/ signal attenuation pots. Two select-able filter slopes: original 4-pole, and 2-pole. Two select-able filter modes: lowpass or bandpass. The filter is all analog, using the same OTA chips and dual transistor design of the original Delta.

Listening w/ headphones or quality monitors is recommended. Watch your levels, some resonance and filter overdrive settings may cause discomfort or strain your monitors. This demo was recorded direct to Tascam DR-05 through a Mackie mixer. No effects, no EQ, just some normalization on video edit.

More details and availability can be found at Modular Grid.

Stay up-to-the-minute on all my endeavors.
