Nermal is a destructive distortion Eurorack module that has some unique sonic qualities. There are 3 levels of distortion ranging from subtle saturation to utter destruction. An integrated modulator can switch or even blend between these modes, with the modulation frequency going well into the audio range, in which case, interesting harmonics and artefacts can be created on top of the incoming audio. Nermal rewards experimentation and unexpected sweetspots can often be discovered along the way. In addition to the onboard modulator, there are external modulation options via control voltages (CV) for the most commonly used parameters. LFOs and envelopes work great, but audio signals are accepted as well and make for the most interesting patches.
Nermal is available from May 2021 as a full DIY kit from retailers. It's fairly easy to complete, with a moderate component count and no SMD or other tricky parts.
"#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."
"In this video, I build the new pale-faced Neutral Labs @nyppy Elmyra 2 and take it for a test drive with my MPC One acting as a sequencer. See https://neutral-labs.com/elmyra2
This is a 4 voice polyphonic semi modular synth advertised for "microtonal exploration", but it can also be used chromatically if you so choose, as demonstrated in this video. Table of contents:

"Scrooge is a sequenced malfunction generator, available as a 42 HP Eurorack module or semi-modular desktop synth. While you can convince it to deliver boomy kick drum sounds, clicky hi-hats or metallic snares, it would much rather be making glitchy artifacts, hollow crackles and horribly distorted growls. It contains a sophisticated and performance-oriented step sequencer with parameter locking and the possibility to control all steps across multiple tracks at once. Its 5 distinct and fully analog voices are made up of special circuits that work without dedicated power supplies, scrounging power from the sequencer control signals instead, which gives them an organic and unstable quality. As a bonus, it means you won’t have to power the unit itself if you sequence it from external gear.
5 distinct analog voices device can work passively without a power supply if sequenced from external gear each voice can be routed to either of 2 main outputs (headphone compatible) individual voice outputs individual voice CV inputs that respond well to audio signals 2 modulation tracks, individually routable to voices 2 modulation CV inputs onboard step sequencer parameter locking per step "control all" mode (change parameters for several steps and tracks at once), great for interactive playing arbitrary step length per track (up to 64 steps) generative algorithm builds random variations on patterns (available while performing), or creates random patterns from scratch pattern chaining (up to 32 patterns) stores up to 128 patterns in 16 banks microtiming CV slew limiter per track can sequence external gear sync output sync and reset inputs MIDI input (TRS type A)"
This is a demonstration of the wide sonic palette possible with Elmyra. I'm using two of them in combination with various other synthesizers and effects units, such as Soma Lyra-8, Make Noise 0-coast, Tasty Chips GR-1, Moog DFAM and Mother-32, Elektron Digitakt and Analog Four, Mooer Ocean Machine, Jomox M-Resonator and a bunch of Eurorack modules.
If you're interested in a panel + PCB set, kit or build, let me know."
"Not a lot of videos about this peculiar synth around, so I recorded this one and focused a bit on the weird side of it, which is where it shines. If you can't be bothered to watch all of it, skip to the last two minutes. And if you have any questions, just leave a comment, I'm happy to help."
Scrat is an aggressive sounding multimode Steiner-Parker filter with a twist: You can change the resonance flavour by plugging in components like diodes, capacitors or resistors (even LEDs and/or light-dependent resistors) directly to the front panel. A set of preset cartridges is also available, which gives you instant access to a variety of filter sounds. You could even make your own. Or go all in and connect some jumper wires to a breadboard for pretty much endless possibilities.
The 2-pole filter (12 dB/octave) supports both high-pass and low-pass mode. Even without external components or cartridges, the resonance behaviour can be changed in various ways via switches on the front panel. Both resonance and cutoff can be fully CV controlled, and the cutoff CV sensitivity can be adjusted as well.
The module contains an adjustable pre-filter drive circuit, which pairs very well with the Steiner-Parker design.
Scrat is available from July 2022 as a full DIY kit from retailers. It's a relatively easy build to complete, with a low component count and no SMD or other tricky parts. A set of 4 preset cards called Nuts (Acorn, Almond, Cashew and Pecan) is also available.
"@nyppy Neutral Labs Scrooge and Elmyra2 are a couple of unique modules - Scrooge is a Sequenced Malfunction Generator capable of producing glitchy and broken electronic rhythms and sequences. Elmyra 2 is a 4-voice digital/analog hybrid drone synthesizer and platform for microtonal sonic exploration.
@matthsmatthsmatths takes them on to create a Track From Scratch using samples and recordings made using only these instruments."

"I've heard people refer to the Nyborg as 'the better Moog', and using both of them almost daily, I thought I'd put up a short video comparing the two. This is not meant to be a full review of either. It's mainly about the sound, specifically oscillators and filters. Both user interfaces and modulation capabilities are vastly different, and you can find reviews and tech specs elsewhere.
In my opinion, there is no clear winner in terms of sound (otherwise I wouldn't still own both). The Moog's oscillators sound warmer, but it can get more aggressive with the filter and overdrive. The Nyborg has a very pleasant sound for arpeggios and is easier to fit in a mix. Without any resonance, both filters sound very close to each other.
Do you have a favourite? Or got anything to ask? Let me know in the comments.
"This is just a quick demo of my Elmyra prototype. You can easily build this synth yourself. I will share the schematics, PCB and code in a few days. A video detailing all the features is also coming up. Just watch this space or drop me a message.
This is obviously inspired by the Soma Lyra-8, which I love, but it's not a clone at all.
Reverb provided by Eventide Space. Next video will have the dry sound as well. The Elmyra delay can get pretty reverb-y on its own.
