My SH5-VCF revision 2 is now here!


The SH5-VCF Eurorack filter is back baby! Revision 2 has all the phat, but none of the chaff. What's different than version 1? What's the same? How to use it, and oh - how does it sound? Let's go!

Akai VX600 Synthesizer Demo [no talking]


This is a six voice analog Akai VX600 synthesizer. Two oscillators per voice, and it takes minimum 30 minutes to stabilize tuning enough to play. Even so, it also wants 3 or 4 autotune sessions. Basses, pads, leads, arpeggios. Please enjoy. While this demo features my original patches, alas - there's no way to backup patches to computer or share them w/ others in that way. It only accepts Roland style Memory Cards. Be sure to check out my patches for other synths available at Gumroad. I also make Eurorack modules with mojo, available in my Reverb Store.

Recorded direct via EPM6 mixer to GO-Mixer Pro-X interface to iPhone, no added effects. The synth output is very hot, so any clipping you hear was overloading the input at the mixer.

Decadent Atmospheric Pads & Soundscapes on Roland XP-30


The Roland XP-30. Loaded w/ tons of decadent atmospheric pads and soundscape presets. Still relevant after all this time. Yes, yes, I hear using presets = bad. But sometimes you just want to kick back and let the imagination ride and give the left brain much needed rest. Headphones, dim lighting and candles recommended.

Behringer Wave Digital Synthesizer User Review [Demo 01]


Today I am giving a user review of the new Behringer Wave. My personal thoughts and opinions. I bought this synth with my own tax refund money. So nobody has input into what I'm posting here today. The Wave is promoted as a faithful reproduction of the PPG Wave 2.3 digital synthesizer in all its lo-fi glory. With a touch of some modern feature additions. While I have tried a friend's original PPG, this is not a comparison to the original. Nor is this an exhaustive how-to, nor covering all features.
Is the Behringer Wave right for you?
What makes the Wave stand out from other synths?
Is the Wave a good value for the money?
Can I recommend the Wave to others?

JU60-VCF Eurorack Filter Adaptation Roland Juno-6/60 Jupiter-8 Now Available



JU60-VCF is an analog 4-pole low pass filter adaptation of Roland Juno-6/60 using a vintage IR3109 chip with a BA662 OTA chip in the resonance feedback loop. This topology was also used on the Jupiter-8, with a switch for tapping the 2-pole mode. Resonance will self-oscillate and produces a nice sine wave alone. JU60-VCF won’t turn your system into a polyphonic synth, but it has a classic sound at a sweet price. Time to get out your favorite stereo chorus modules and pedals!

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


Today it's the battle of the 8HP filter modules!
Six of 'em, says the squinty-eyed man with no name.
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

0:00 Intro
0:40 Bassline sequenced
3:24 Arpeggio sequenced + Reverb + Delay
6:09 Bass Sweeps, various res settings

Details
Osc | 101-VCO square + saw + sub
Buffered Multiple | My one-off Buffy Bot is used in 1-into-6 config.
The buffered osc signal is going to each of the 6 filters.
Envelope | 2xADSR is stack-cabled to the various CV inputs.
The CVs are zero'd out until each filter gets dialed up.
Delay | Timefactor
Reverb | Big Sky

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.

Feed External VCOs into the Korg MS-20 Synth using KVP [Quick Tip]

Quick Tip using the KVP to send external VCOs into the MS-20.
KVP stands for Korg Voltage Processor, and is derived from the vintage
MS-02 voltage processor no longer in production. As you're already aware, you can use KVP to convert eurorack pitch (v/oct) to the Korg standard (hz/v). And use your sequencer to control the MS-20....

But what about the other (Korg hz/v)-to-(Euro v/oct) pitch converter?
Sure! Use the MS-20 to control your eurorack VCOs.
Take it only one step further to send the external VCO output INTO the MS-20 external input.
To add more VCOs to the MS-20 oscillators for big fat sound.
I will show you how to patch it up.
It works for the vintage MS-20, the MS-20 Mini reissue as well as the Behringer K-2.
And any manufacturer synth using the Hz/v standard.

Some shaky cam footage, I threw this one together in haste...but don't hate :D Hit that LIKE, COMMENT & SUBSCRIBE now.

Some fx added
Delay: Timefactor
Reverb: Big Sky

KVP and many other cool eurorack modules are available in my Reverb Store
Recorded direct to Tascam DR-05.
