Gyrinx VCF Uninhibited Functional Testing Audio [Demo #4]

Been short on time through the holidays, so I thought I would make a quick video while I work :D
This one is a functional testing routine I'm performing on another batch of Gyrinx VCF modules for sale.
It is very revealing as to the sound character as I quickly run through all of the functions of the filter without thought to sound design.
Sound source is Pittsburgh Modular Primary Oscillator saw and square.
Off camera I have a Batumi for LFO modulation.
Sequencing by Keystep Pro.
No added effects or processing, recorded direct.
Watch your levels using headphones, some harsh tones ahead.

Gyrinx VCF is a eurorack topology of the Synton Syrinx Filter section.

Sketchy Labs Freak Shift Eurorack Module [Demo #1]

Today I am auditioning the Sketchy Labs Freak Shift module.
The design is specially derived from the Bode Frequency Shifter.
There are literally sweet spots at every turn of the pots on this one.
In this video I'll briefly discuss this module and patch up some wierd sounds.
The focus is on demonstrating a range of evolving sounds of the frequency shifter.
I'll endeavor to make something more musical using the Freak Shift in a future video.
This video is not sponsored or endorsed by the Doc Sketchy.

0:00 Intro and brief discussion of patching
0:54 LFO as Mod input for phaser type sounds
1:24 Using 2 LFOs for Sine/Cosine modulation

Pittsburgh Modular Flamingo [Safari] Patching [Demo #1]

Just got the new Pittsburgh Modular Safari Flamingo module in.
It's a harmonic interpolation device using a previously unrealized method known as center clipping.
Flamingo can deform and undulate your audio sources in new and interesting ways.
In this video I'll discuss Flamingo and make some patches.
The last section will show how well Flamingo processes control voltages.

SH5-VCF: Beauty & Terror [Demo #3] (no jibber-jabber)

Some Darkscape Eurorack patches featuring the SH5-VCF.
Exploring some near-oscillation resonance sounds.
And frequency modulation of the VCF which this diode filter is so good at.
This time around using Big Sky Reverb and Timefactor Delay.
If you want to hear the naked filter alone the first two demos I made were bone dry no effects :D

I used different colored patch cables, so maybe you can glean what is going on.
If there are questions about that go ahead and pepper me in the comments.

SH5-VCF is all-analog eurorack adaptation of the Roland SH-5 Synthesizer Filter and Mixer.

Introducing SH5-VCF Dual Filter Eurorack Adaption (Roland SH-5) [Demo #1]

Introducing the SH5-VCF.
An all-analog eurorack adaptation of the Roland SH-5 Synthesizer Filter and Mixer.
The Lowpass filter is a diode ladder configuration using open-collector matched transistor pairs.
No filter-on-a-chip here :D
Similar Lowpass configuration was used in the Roland SH-1000 and the earlier System 100 (not 100m).
The dedicated Bandpass section introduces voltage control modulation not found on the original.
While the two filter sections are routed in parallel, that doesn't stop you from being able to re-route them in series configuration.
What you can expect from the SH5-VCF is the quintessential Roland modular filter experience.
These are all reasons I say it is time to get a little more serious.

Behringer RD-9 [User Review] Rhythm Designer Analog Drum Machine

Today I am giving a user review of the new Behringer RD-9 Analog Drum Machine. The RD-9 is an affordable re-issue of the Roland TR-909 all-analog circuitry. With some updated functionality. This is not another typical audio comparison video, nor tutorial. How does it sound? Whats the design, construction quality and workflow like? Do I like the features? How does it compare to other analog drum machines currently available? I'll break it all down for you right here, right now.

Behringer RD-9 Doing Slower Tempo

The Behringer RD-9 Rhythm Designer drum machine just rolled in the door. Today I'm showing 3 little vignettes of what it sounds like doing slower tempo stuff w/ SH-101, TD-3 and some eurorack stuff.

3 parts:
0:00 90 bpm w/ Roland SH-101 andfx processing on some of the individual outs. You might like headphones or monitors to get the full sound.
1:18 80 bpm w/ Eurorack + Keystep Pro. RD-9 through Big Sky then DBX 160A compressor
3:01 100 bpm w/ TD-3. RD-9 low tom getting lo-shelf at mixer then Reverb + Delay. Some use of Probability and note-repeat (ratchet) on the closed hats.

The wave designer features were not used.
No mastering or post processing. This recording could have used some. The RD-9 definitely has punchy transients, I kept turning my record level down but still peaking my Tascam DR-05. So the average level sounds kinda low to me.

GSE Six 8HP Filter Modules Shoot-Out [comparison] [vs]

101-VCF, SH2-VCF, JP6-VCF, Delta VCF, Pro VCF, and 4023 VCF.
You know them, but what are some of the sonic differences?
Watch out, some skreechy resonance ahead. They're filters after all :D

G-Storm Electro Patches for Roland Jupiter-6 [Demo #4]

Auditioning some original Roland Jupiter-6 patches available for download. I had the good fortune of getting another Jupe in the studio. The previous one that had Europa was sold. This one is an earlier model, and was purchased dead. After bringing it back to life and calibration... Soon I had quickly re-programmed all my favorite sounds.

This video is un-rehearsed, so lots of noodling. Not dwelling too long on any one sound, to save your time. So if you skip around, you might miss something. Just sayin' :D Chord stabs, sweeps, bass, apreggio, sound fx, leads. Patch F7 is my template (default, or blank) patch. Patch F8 is my scratch patch, for when I can't remember what location I wanted to over-write.

The Roland Jupiter-6 has only rudimentary midi capability: simple note on/off and patch change midi message only. So, these patches can only be dumped all at once using the cassette interface. BE SURE TO BACK UP YOUR OWN PATCHES BEFORE OVER-WRITING THEM!

Download the patches as an mp3 audio file on my DOWNLOAD PAGE. I have used the JP-6 VERIFY function and confirm the audio file is good.

No additional effects or processing was used, aside from some normalization. Video was made in great haste - so it's un-edited, some audio levels are clipping. And sometimes scratchy volume pot.

Gyrinx VCF + Pittsburgh Primary Oscillator Audio [Demo #3]

Today I am running the Pittsburgh Modular Primary Oscillator through the Gyrinx VCF.
And throwing a bunch of LFOs and short triggers at them.
Expect more saturated noise and a few harsh tones in this one.
As well as strange bass sounds and fx bleeps.
The sequenced stuff is going through my 2xVCA

GSE 101-VCO vs SH-101 + 101-VCO Tuning Mod [Demo 4]

Today, I am comparing my 101-VCO to the original Roland SH-101 synthesizer.
How close to the original is my 101-VCO?
Saw, Pulse, Pulse Width Modulation, Sub, and Noise waveforms.
The SH-101 did not have the Triangle waveform.
At the end of the video I'll play both of them together, just for fun.

I'll also show you an easy mod for the 101-VCO so that it's pitch CV can
match the tuning of the original SH-101.
It involves adding a 1206 470K resistor to R19 previously denoted "DNP".
All 101-VCOs I make and sell henceforth will have the resistor already installed.
And tuned to match the SH-101 as it should be.

Left Channel = 101-VCO
Right Channel = SH-101

GSE KVP Pitch Calibration Procedure w/ Korg MS-20 + Keystep Pro

In this video I will be showing how to calibrate my KVP (Korg Voltage Processor) module.
While I test and calibrate the tuning of all modules, re-calibration may become necessary when the settings get too far out of whack.
I will give some helpful tips as well as a detailed step-by-step explanation of the calibration process.

This video is of a technical nature.
If you're wanting basic information about the KVP and its uses, be sure to check out my other video
and on ModularGrid

Timestamps
0:00 Intro, Helpful Tips, Setting Up the Keystep Pro
KEYSTEP PRO: Global Setting CV Base Note = C-2
2:28 V/OCT to Hz/V Calibration
Be sure to trim FREQ with the "low C" note
And trim WIDTH with the "high C" note.
7:01 Hz/V to V/OCT Calibration
Be sure to trim FREQ with the 'A' note
And trim WIDTH with the "high C" note

Keep in mind the KVP is an analog signal converter, controlling an analog MS-20 synthesizer. And when converting Hz/V to V/OCT, we may be also using the MS-20 to control yet another analog VCO device. Given these things, the pitch won't be absolutely perfect - but the base frequency and tracking should be well within musically acceptable margins.
