XaVCF Eurorack OB-Xa Filter Adaptation Now Available

The XaVCF is a faithful adaptation of the OB-Xa filter in Eurorack with added features. As with the original, the XaVCF has two filter circuits to choose from! The heart of both designs having each its own Alfa reissue AS3320 chip. The XaVCF has the original Modes: a 4-Pole standard Lowpass circuit, and a 2-Pole Lowpass derived from a State-Variable circuit. Additionally there are 1-Pole Bandpass and Lowpass modes not available on the original!

Caution! Aggressive resonant peaks ahead, watch your levels.

This module must be doing something right!

XaVCF Test Filter Circuit [Audio Only Demo]

I've been getting requests for demos of my upcoming XaVCF module.
It will be a eurorack adaptation of the OB-Xa filter.
More info at Modular Grid
You know this sound from Rush Tom Sawyer and Van Halen's album 1984.
While we're all eagerly awaiting the module prototype I thought
I would share a brief sampling from a mini-lab test circuit.
A more thorough overview of the module will happen when it gets built.
So be on the lookout for that one in the near future.

The XaVCF will sound pretty far out.
We're talking about full on intergalactic blast off here.
Headphones recommended. BUT!...
Watch your levels, thick resonant sweeps ahead!
Prepare for ignition...

Makeshift VHS Tape Ribbon Controller In 3-Minutes

Haven't had any synth repairs or DIY hacks in a while.
A buddy sent a FB video link and asked what's up with this.
Somebody was using a videotape as a makeshift ribbon controller.
Using the tape to send a control voltage to their modular gear.
You may have seen something like this, but wondered about the details required.

Does it actually work?
If so what are the necessary steps?
Let's find out.

Behringer VC340 Vocoder + 101-VCO [Demo #1]

Today the gorgeous sounds of the Behringer VC340 Vocoder
Strings and Choir paired with my 101-VCO on arpeggio.
101-VCO going to my 101-VCF for that classic SH-101 sound.
Future Retro Transient is going to the vocoder mic input.
Transient is modulated by Batumi to result in those
shifting vocoder effects - almost chanting/talking?
Arturia Drumbrute Impact is clocked to the Beatstep Pro.
Some Big Sky reverb and Timefactor Delay.

Recorded direct to Tascam DR-05.

Behringer Neutron First Patch [Demo #1]

Today a first patch soundscape/sequence on my new muse,
the Behringer Neutron. Listen that on headphones. No, really.

I haven't come across any compelling demos on the Neutron.
It has great specs, but not much attention was given.
Until I had a chance to play one last weekend at the Dallas Synth Meet.
HOLY SHNITZEL. This thing blew me away.
The analog BBD delay section is one of the nicest.
So responsive, expressive,
...and lovely thick feedback harmonics.
You can ride the feedback right up to pure chaos, then
back away. It will abide your every move.
And every time I tweaked something it got better and better.
I am really looking forward to getting more cutting edge
sound design with this one!

Sequencing: Beatstep Pro
Recorded Direct to Tascam DR-05.
Additional delay using Timefactor Delay.

SH2-VCF IS BACK! Version 2 using BA662 clones

I am happy to announce the SH2-VCF is available once again.
It was very important that Version 2 had all the same glory.
And the BA662 clones this one uses can definitely deliver the goods.
