Turismo - Environment Sound Design

video upload by ALM TV

"Our Eurorack modular workstation the 'Turismo' is well suited for sequencing beats and groove box style patching but the versatile system can fit equally well into less structured environments. In this patch we explored using the Turismo for realistic environmental sound design, making use of it's plethora of utilites and interesting sound shaping capabilities to create a custom environment with realistic rain and thunder sounds entirely synthesized by the system.

For a more detailed description of this patch, please see our full writeup on the Busy Circuits blog: https://busycircuits.com/blogs/latest..."

Antonus Step Brother with Elektor Formant by Erica Synths improvisation

video upload by Antonus

"Testing the finished Elektor Formant DIY KIT from Erica Synths.
Improvising using the Antonus Step Brother for play the Formant. Very special and particular sound and behaviour in the Formant, but the Step Brother connects in a very powerful way. I love how also they match in dimensions, Step Brother fits perfect on bottom of the Formant. Very fun and powerful combo!"

The Queen of Industrial Grunge Got an Upgrade — Sophisticated Dirt!

video upload by Cinematic Laboratory

"#Elmyra2 v2.4 — What’s New and Improved Sound Engine

Higher sample rate and improved wavetable resolution → noticeably cleaner top end. New wavetables added. Overall mix saturation refined, with “soft” (122) now default. Knob value stability and tuning precision improved.

Filters
New comb filter (codes 3321/3322). RESO = damping, CUTOFF = delay time, with optional pitch tracking. Ladder filter reworked — now true multimode (LP/BP/HP) with higher quality. Ladder LP (331) is the new default filter. State-variable filter retains LP/BP/HP modes (341–343) but with improved gain staging, resonance, and cutoff ranges.

Delay & Reverb
Delay fully re-implemented → cleaner feedback, no lock-ups.
Added proper reverb engine controllable with delay knobs.
Code 441 = delay (default), 442 = new reverb, 4411 = legacy lo-fi reverb.
TIME = decay, FDBK = color, MIX = blend.
Dry/wet crossfade curve improved for smoother transitions.

Modulation
New MODP: oscillator hard-sync (orange LED, position 5).
MOD controls the synced oscillator pitch.
LFO1 knob-motion recording (code 2413) — record live movement of LFO rate. Sequencer output to LFO1 possible (243v).
Per-voice sequencer clock divider (11sv).
Digitally controlled envelopes in multiple short modes (221v → very short … 224v → disable). Detune MODP range expanded.

Scales & Chromatic Mode
New musical scales for chromatic mode: major, minor, major pentatonic, minor pentatonic (CHRM + 11–14). Scale selection now unified under the CHRM button. Knob-to-pitch mapping in chromatic mode is now linear and exact.

User Interface & Workflow

LED feedback overhaul — REC and PLAY flash to confirm code entry, sequence record, mute, and drone states. Quick mute/unmute voice (MODP + PG long press). Quick octave switch (MODP + double-tap PG).
Pink MODP LED at startup identifies firmware 2.4.
Touchpad LEDs more reliable during operation.
Drone and mute response feels snappier.

Under-the-hood Fixes
State-variable filter crash fixed (previously triggered by fast cutoff modulation).
Improved detune, filter, and delay behaviors under modulation load.
Sequencer timing more consistent with internal clock."

ODD-1 Overview 05: LFOs, Macros, Patching

video upload by Oddment

"This is the fifth in a series of videos to show all of the ODD-1's functions in more detail. In this one we show off the LFOs, Macros and how to create modulation connections. There are 4 LFOs, 3 Envelopes, 4 Macros (assignable knobs), 4 Control inputs and MIDI information that can all act as modulation sources. Any parameter on the device is a parameter destination. Unlimited connections are made by holding down a destination parameter and then pressing or twisting a modulation source."

Notes from the .txt
ART SPRINGER STRIKES AGAIN (free)
Reviewed by Mike Metlay

All right, gang, I know what you're expecting in this space, so I'll oblige you and get it over with. Ready? Here goes: "WAHOOLAZUMA! Everybody's favorite twisted puppy is back from the audio torture chamber, and he's brewed up the most brain-slashing package of monstrous elektronoyze EVER! This stuff's great for warping your brain patterns, killing your cat, etc..."

Okay. Happy now? Good, now let's get serious. I heard from Art recently that he didn't get a terribly good response to his first mailing, and that few, if any, XUG members looked him up for his second set of patches

He seemed in a pretty good humor about it, but I couldn't help wondering if my presentation of his patch set didn't scare a lot of people away just by the wording. So, with a new patch set from Art (more diverse than the first two) in hand, I'd like to try again.

One of the most unhealthy trends I see in today's patch-editing software is the patch randomizer, that cute but overused utility that generates random patches at the click of a mouse. Literally thousands of these random patches are being sold by unscrupulous hackers as "original sounds," and a whole new generation of MIDI morons is springing up (pardon the pun) whose idea of "good programming chops" is the ability to tweak a randomly generated sound into something that (almost) works. No program of this type exists yet for the xpander, and I'm glad of it: the lack of computer-generated garbage on the market forces the user community to seek one another for new ideas, rather than some electronic I Ching. We come together in this Group to share ideas and learn from one another and I believe that studying another human being's work beats watching a computer coughing up random numbers. Which brings us to the music of Art Springer.

In my opinion, these patches are important. VERY important. I get so enthused about Art's work because I see in him a reflection of my college days, when I puttered about with ARP and Buchla modular monsters creating sounds for the sheer joy of it, putting together tonalities never before heard on Earth rather than trying to make a realistic shakuhachi. This was, and often still is, the meat and potatoes of electronic music to me. And when I hear Art telling me that people- Xpander users!-are returning his work because it's "too weird," I know something's wrong. The Xpander isn't a sampler or a digital piano. It's not an imitative instrument by nature. It's a powerful, multiply interfaceable modular synthesizer with a great deal of flexibility. Art Springer takes a stance on its use that no other Group member has had the courage to try: using its Power as a CV percussion device to enhance the sounds of his more traditionally oriented synths. (By the way, Lionel and I are big fans of his music ... it's not as inaccessible as you might think, and the odd tonalities make his dance pieces a lot of fun.) This is a new idea to a lot of you, and I don't blame you for being frightened. But it's better to learn from someone whose ideas differ from yours than to convince a computer to feed you something safe. I'd like to suggest something simple to start with: get one of Art's sound sets, trigger your Xpander with your drumbox, and try writing music with these sounds as part of the atmosphere rather than conventional drum noises. Or do something completely different. The important thing is to try to expand (hm) your horizons to something new. These sounds of Art's do take getting used to, but I think you'll learn a lot from them. Trust me."

Video in the listing for another mod previously posted here. "One-of-a-kind modified Yamaha RX 17 1987 12-bit programmable drum machine featuring two ROM modulation patch bays, a joystick for performance control of four pre-set effects (which may also be combined on the diagonal axes) and pitch control. These modifications generate an array of bit crushed, flanging, glitching, distorted, delayed, tonal effects, flams and digital noise. Five patch cables included- these can be 'stacked' for even deeper audio manipulation. The unit functions as normal when the patch bay is not in use. Only one available.
