GODSPEar | Oxford OSCar Eurorack Filter Translation [Demo #1]

Today I am introducing GODSPEar, my homage to the Oxford OSCar filter in Eurorack format. GODSPEar is the only filter used in these audio recordings. Detailed explanation of the module and patch examples will be in a forthcoming Demo #2. Audio recorded direct to Tascam DR-05, some additional compression and normalization used in the making of this audio.

Pittsburgh Modular Taiga [Sounds Only Demo] |No Talking|

The anticipated new Pittsburgh Modular Taiga synth just rolled in the door. I knew I was going to be messing with it all day, so I figured may as well film it and share some curated noise with you. Patched some bass sounds and one clip making weird sound effects. Sounds really good, looking forward to using it in some new tracks.

This video was not sponsored by Pittsburgh Modular, nor Cre8audio. Paid for this unit with my own money. After all, I'm just another synth enthusiast just like you :D

A small amount of delay coming from Behringer DD400 for stereo widening only. Otherwise recorded direct to Tascam DR-05, no additional mastering or effects.

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.

Modbap Per4mer Performance FX [USER REVIEW + Demos] Eurorack

Today I am giving a user review of the Per4mer FX module by Modbap Modular.
The Per4mer is a DJ-Style Quad FX module designed with Hip-Hop, Trip-Hop, and Glitch music in mind.
But it also dishes up well for Trap, experiemental, and ambient excursions for sure.
But is Per4mer worth the coin?
Is it the right module for you?
I will be giving some quick thoughts about the build, and dig into some beat and loop mangling.
At the end I give some concluding remarks weighing the pros and cons.
My videos are not sponsored by anyone.
I purchased this product with my own moolah.
So you can expect my own objective opinions and observations.

Behringer RD-6 [USER REVIEW] Analog Drum Machine

Today I am giving a user review of the new Behringer RD-6 Analog Drum Machine.
The RD-6 is an affordable re-issue of the Roland TR-606 all-analog circuitry.
With some updated functionality.
While I have a TR-606, this is not another typical audio comparison video.
Is the RD-6 a good value and sound for the money?
How well does it really work for eurorack modular systems?
Has anything been improved over the original?
How does it compare to other analog drum machines available?
I'll break it all down for you right here, right now.

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.

SH2-VCF Reporting For Duty! Eurorack Filter Module Demo #2

Following up on my prototype demo, the SH2-VCF is finished and reporting for duty. My SH2-VCF is a filter adaptation of the Roland SH-2 analog synthesizer filter using BA6110 op amps in place of the extinct BA662 chips of the original.

In this video I'll keep the talking to a minimum and explain how I resolved the BA6110 issue. And then put the filter through some paces including a massive kick drum, and an example track using TWO of these filters.

Be warned - some huge resonant kick drums ahead!
Audio recorded direct to Tascam DR-05 except the last part which has some delay.

RM&S Ring Mod + Sub-Octave Generator now available

My Ring Modulation + Sub-Octave Generator module is now available at Reverb dot com!

RM&S is a 4HP Ring Modulator and Sub-Octave generator. The Ring Modulator is an active, CMOS-based circuit adapted from the ARP Odyssey. Ring Mod is usually generated from inserting square wave VCOs to Input 1 & 2. But that shouldn't stop you from sending sawtooth, wavetables and noise sources through this.

The Sub-Octave Generator circuit is derived from the Roland SH-101 and provides -1 and -2 octaves from a square wave plugged into Input 1. Many VCOs put out varying degrees of signal amplitude, a trim pot is provided to adjust input impedance of VCOs for the Sub-Octave Generator circuit.

Output jacks include: Ring Mod, summed Ring Mod + Sub-1, Sub-1, and Sub-2. The RM&S is hand-crafted in the USA.

Measured Current Draw: 2mA on -12V, 5mA on +12V, 5V not used

RM&S Ring Mod & Sub-Octave Generator Eurorack

Square waves and Pulse Width Modulation are among my favorite synth things. However, CMOS Ring Mod to me is like PWM on steroids. Today I am demonstrating my prototype module RM&S. It takes two square wave inputs and derives CMOS Ring Modulation based on the ARP Odyssey. Square wave Input 1 is used to generate -1 and -2 octave Sub-Oscillators. But this module has another trick up its sleeve. An additional output is provided which sums both Sub-1 and the Ring Modulation for a super-fat synth tone!
