Who becomes silverware first? - 10 minute LFO filter sweep and semi-generative Eurorack jam

video upload by thesrabbit

"This sonic experiment was inspired by the Dreadbox Erebus LFO having a whopping 10-minute long cycle time. Therefore, I thought it might be fun to run that LFO into every single filter I have with a CV input, including big analog polys with a VCF control input on the back intended for expression pedals. The honorary VCFs include: 2x Roland System-500 521, G-Storm Electro SH-2 and SH-5, Dreadbox Erebus, Oberheim OB-X8 (OB-X SEM LP mode), Sequential/Oberheim OB-6, Roland Juno-6.

Interestingly the filters on the big polys don't open all the way. I assume this has something to do with the inputs being calibrated for expression pedals rather than Eurorack CV. According to my oscilloscope, the Erebus LFO range is -5v and +5v. This is pretty typical for Eurorack. I set the cutoff at about 50% for all the filter modules. This seemed to work perfectly. But I was not able to do that with the polys. With the cutoff at 50%, the filters would open up all the way, but they wouldn't close nearly enough. I had to bring the cutoff completely down, and as a result, the filters on the polys wouldn't open up all the way. I did alternate takes where I walked around and tried to smoothly nudge each one up in order to get the filters fully open, but that was a disaster. In retrospect, I could have set up a one-shot MIDI LFO to do this and triggered it once at the right moment, but I already had enough things to worry about.

One of my audio interfaces is dead or dying, and it keeps ruining takes and sometimes crashes Logic. I finally turned it off and went with my lone Focusrite Scarlett 8i6, which has always been solid. But now I had an extra synth without an input and I wanted to have the polys on their own tracks so that I could blend them in with the Eurorack stuff to taste. And there's no possible way I could overdub since the whole point is to have one LFO sweeping all of the filters at the same time. I ended up resorting to an old 1989 JVC cassette deck to record the OB-6. So that shot at the opening of the video is legit. There's such a big wall of sound here that it's impossible to tell if it ended up adding any saturation. It definitely added some hiss and crackles but that's fine in this context. The cassette itself is ancient, cheap consumer grade, 60 minutes per side. I ended up recording over some 90's black metal that had been there since, well, the 90's.

To add to the grit and grime, I intentionally ran the filters from the Eurorack straight into the audio interface, bypassing the typical flow through VCAs. Ok, fine, I totally forgot about the VCAs, but it sounded extra dirty, so I didn't stress out too much. I certainly wasn't going to power everything back on, tune everything up and do another take because of it.

Obviously when the filters are closed or nearly closed for several minutes, there needs to be something to fill that gap. That's where the generative stuff comes in. There's 3 different sample and hold circuits feeding different things, including back into themselves in one case. Some voltage is running through different logic gates in conjunction with other, steady LFOs. Since I'm out of filters, the sound consists of pink noise through a VCA, triggered at random by a very short decay envelope. This runs into a recovery tape delay module, that gives sort of a slapback effect.Then there's a single oscillator, pitch controlled by another S/H circuit run through a quantizer and then running into the spring reverb tank. It's also triggered by the same random voltages triggering the noise hits. Then there's the Mutable Instruments Plaits, making the plinky plonky sounds, again everything triggered at random. It's running into the majestic Calsynth Typhoon.

The last thing to note is that the Erebus LFO also acts like an automated fader to increase and decrease the level of the VCA where all the rhythmic sounds are running through. I simply inverted the signal of the LFO output to do this. As the filters open up, the VCA level diminishes. When the filters fully close, the VCA level increases to maximum.

Last last thing. That knob twisting near the beginning isn't for sci-fi FX, though that's an added bonus. I was simply trying to get the LFO back to its "starting position." I didn't quite succeed. I don't believe the Erebus has any sort of LFO triggering mechanism to help with this. All good though.

Roland Juno Chorus eurorack comparison

video upload by John Schussler

"I'm a big chorus fan, and am continually surprised there aren't more of them as stand alone modules in Eurorack. The most famous chorus was originally shipped in the Roland Juno line (6, 60, and 106), and is what's replicated in these two modules I'm looking at today.

The Feedback Chorus 106 has been out for a while, and is now discontinued because they can no longer get some of the NOS (new old stock) parts they use.

The SoundForce uChorus is brand new, and has substituted an STM and some other new bits to make up for the MN3101 driver IC that's no longer available.

Both are following the original circuit behavior as closely as possible.

I compare them here to see if one is better than the other.
Spoiler: I can't hear the difference. Can you? Let me know in the comments.

SEM vs SEM - November 2023 edition

video upload by John Schussler

"The G-Storm Electro SEM VCF arrived the other day, and I figured I'd give it a listen in comparison to what, up to this point, I think is the best SEM eurorack module: the Studio Electronics SEM VCF.

(Spoiler alert: The G-Storm gives the SE a serious run for its money)

I've also thrown in the Bubblesound SEM20 and an AMSynths Obie XA. The Bubblesound is mostly SEM, but with some MS-10 bits grafted on that makes it more aggro. The Obie XA isn't a SEM at all, different chip, but is also modeled after an Oberheim filter so I figured I'd toss it in for contrast.

VCO is a Befaco Pony, first on saw then on square. Sequencer is a Clank Chaos. Envelope is Zadar.

Be forewarned: a lot of this video is me going back, and forth, and back, and forth, and back and forth between modules. Don't get seasick.

Sequential Drumtraks Drum Machine Repair

"Audio + Video by G-Storm Electro c. 2023

Today I'm investigating issues with a Sequential Drumtraks. While it is making sounds, the display is glitching out and the control functions are not working. In the end it was only incidental I was able to get it working again, for reasons I don't fully understand. The same phenomenon happens with my Drumulator, that's how I knew what to check for. It's my hope posting this video, that someone more knowledgable will be able to comment about this phenomenon.

This video is posted for general information about my experiences. Always observe safety working on electronics, and never tinker around inside power supplies without first unplugging the power cord. If you're not sure about anything, there's no shame in taking your instrument to a qualified service technician.

Since filming the video, I've discovered the batteries are still made in Japan. Also, the numbers on the battery may or may not necessarily be a date code. My new battery says 2132, so maybe it was made in 2021? Since the manufacture date and date installed may differ by a couple of years, I now write a date on the battery with a sharpie when I install it."

CHOOSING A TANK

GROUNDING CONNECTORS (5TH character in tank model #) Type A or C is best. SIZE & NUMBER OF SPRINGS | Short length and Medium Length is best. Long length (approx. 16”) may need resistor R8 decreased to 100-ohms for a boost in power. I am happy to switch the resistor for you based on your needs, just let me know before I ship your order out. 2 or 3 number of springs are known to work well. INPUT IMPEDANCE | (2ND character in tank model #) | any except “F” (1475 ohms, has not been tested). OUTPUT IMPEDANCE | (3RD character in tank model #) |“B” known to work best, all others untested. TANKS THAT WERE TESTED AND KNOWN TO WORK WELL | Vintage Folded Line, Medium size, 3-spring, as those used in a Roland Space Echo | Accutronics BAB3C1B Medium size, as taken from a Fender Sidekick Amp | Accutronics 4AB3C1B Long size 16”, 2-spring (R8 to be changed to 100-ohms for best performance). MOST RECOMMENDED | Ruby Tubes 2EB2C1B short size 9”, 2-spring, has plenty of drip and feedback with a size to fit many different case scenarios.

SPECs

Module Depth: 50mm | Current Demand: +12V 39mA, -12V 34mA, 5V not used

Note: due to RCA jack placement and chunkiness of some RCA plugs, it may not be feasible to mount this module on the bottom row of your system rack. Please refer photos. A workaround that might work is to try a cable with 90-degree RCA plug ends."

"The 101-VCO has been re-tooled in 12HP! Version 2 continues its authentic realization of the Roland SH-101 Oscillator adapted to Eurorack: that lovely Sub-Octave Generator, that snowy Noise Generator, an integrated Mixer section to bring all the waves together.

Now in revision 2: Improved tuning stability using power rail voltage references. Simplified tuning via coarse/fine tune knobs. Individual waveform outputs without need for any expander module.

101-VCO expands the original SH-101 features to reveal more potential of the 3340 chip: Triangle wave and exponential FM. And 2 flavors of Linear FM: Lo Range to find those vibrato sweet spots, and Hi Range for full-on Linear FM madness. Expand the palette of original sounds using an external CV signal for Pulse Width Modulation that is summed against the initial Pulse Width amount. While the initial PW amount can go right up to the edge of vanishing, PWM can take the Width right down to 0% up to 100% for complete cancellation.

Great care was taken to keep the 101-VCO fully analog circuit as close to the original as possible. Featuring an Alfa AS3340 re-issue chip at the core of the design, surrounded by eight 20mm slide pot controls. With the conventional coarse/fine tuning knobs it will provide full audio range, whether using the v/oct input or not.

Every 101-VCO is meticulously hand-crafted in limited quantities, not mass-produced, and ready to rock your modular world. Includes 16-pin-to-10-pin power connector cable.

Coarse Tune Knob | Initial oscillator frequency

Fine Tune Knob | Initial oscillator frequency, +/-6 semitones range

FM Slider | Amount that an external signal will modulate the frequency

FM TYPE Switch | LO for vibrato, HI/EXP for more dramatic frequency modulation

PULSE WIDTH Slider | initial Pulse Width amount

PULSE WIDTH MODULATION Slider | The amount that an external signal will affect pulse width

SOURCE MIXER Sliders | Adjusts the amplitude amount of each waveform going to the MIX output

SUB-OCTAVE Switch | Select between -1 octave Square, -2 octave Squrare, -2 octave Narrow Pulse

V/Oct Jack | Pitch Initial Frequency input for connecting keyboard controllers or sequencers

FM Jack | Plug in external signals to modulate Pitch here, such as LFO or envelopes

PWM Jack | Plug in external signals to modulate the Pulse Width here, again LFOs are typical

Individual Waveform Output Jacks | These jacks always output their buffered, DC-coupled signals regardless of Source Mixer settings

Eurorack Formant Filter Comparison

video upload by John Schussler

"I now find myself with 3 separate filters that do "formant" filtering, so clearly it's time for a comparison. I'm literally getting my ya-yas out. And my yi-yis, and sometimes my wa-was. Just depends on where you turn the knob....

There are other formant filters out there, this isn't all of them, but it's all the ones I have, so don't assume this is the exhaustive comparison.

Formants are fun. And though I don't get into it much in this video, using formant filters for "regular" duties with only mild formant effects can be quite interesting.

Actually, using formants sparingly should probably be the rule. There's definitely too much of a good thing possible here....

E-MU ESI-32 for Pure Lofi Sampler Bliss [Demo]

video upload by gstormelectro

"Video and audio by G-Storm Electro c. 2022

Today I'm exploiting the ESI-32 rack sampler for lofi/crunchy/funky sound in multi-timbral mode. Drums were sampled at mono 22K then downsampled to 12K bandwidth, everything else down to 8K. All you're hearing is the ESI-32 sampler including built-in chorus, and internal LFO applied to autopan/vibrato. The audio was recorded direct to Tascam DR-05, no additional effects or mastering.

ESI-32: bit of an underdog, in that early 90s era when samplers started to overcome their limitations of memory, bandwidth, storage media, and processing capabilities. At a fraction of the current selling price for other vintage samplers of the late 80s that preceded it."
