You might remember the stand alone version of OVUM from previous posts here. OVUM has now been ported to eurorack.

Introducing OVUM for Eurorack - analog oscillator bank

August 6, 2025 - Crows Electromusic, a small synth company fromVancouver, Canada, is thrilled to introduce OVUM for Eurorack, a modular adaptation of our standalone synth OVUM. OVUM for Eurorack is a powerful, all-analog, drone and modulation source designed for exploratory sound synthesis, ambient, drone, and noise music. With five individually controllable and individually routable triangle-core oscillators, OVUM for Eurorack gives you a bank of raw material ready for use in your modular system - as droning dissonance, thick chords, or slow swelling modulation signals.

Features:

• 100% analog circuitry
• Five triangle-core oscillators
• Crossfade between triangle and square waves
• Switch each oscillator to audio-rate or LFO rate
• 4 individual outputs, normalled to 1 main output
• One-control-per-function interface
• 20hp, 3U eurorack standard
• Handmade in Canada

OVUM for Eurorack is our third release, and our first Eurorack module.

It builds on what we’ve learned making standalone products; the palm-sized FM drone box Lore, and the original OVUM. The main challenge of adapting a standalone synth to modular is: how does this fit into a modular context? Five more oscillators is always useful, but with OVUM for Eurorack we’ve built something that can be more than that - an instrument with space available to interact with, either as the voice of your composition, or as the control center for your modulations. We hope OVUM for eurorack will be the place your hands go first when you’re performing a patch.

While it’s designed with ambient, experimental, noise and drone music in mind - we think OVUM for Eurorack is going to be at home in virtually any type of modular system.

OVUM for Eurorack is available now for $150 USD / $200 CAD.

Crows Electromusic is a small synth company based in Vancouver, Canada. Started by Cory Alder in 2023. Crows’ goal is to develop new hardware instruments that challenge the established ways we interact with sound and music creation. Their first product, OVUM, was released in 2023, and their second product, Lore, was released in early 2025.

Introducing Lore - FM oscillator pair by Crows Electromusic

Press release via Crows Electromusic:


March 26, 2025 - Crows Electromusic, a small synth company from Vancouver, Canada, is thrilled to introduce Lore, a standalone all-analog tool for exploratory sound synthesis, ambient, drone, and noise music. With individual controls for each function, Lore gives direct control of two independent triangle-core oscillators and can be switched to an FM synthesis mode to unlock a wide range of complex tones. The instrument’s unique un-quantized interface is perfect for exploring pure tones, drones, and FM sound textures.

Features:

• 100% analog circuitry
• Two triangle-core oscillators
• Crossfade between triangle and square waves
• One-control-per-function interface
• Fully standalone, just add headphones
• Transparent bioplastic enclosure
• USB powered
• Handmade in Canada

Lore is our second release, building on what we’ve learned making our first product OVUM analog sound explorer. We had two goals in mind during development: first we wanted to make something that could create a harsher and more aggressive sound, and second, we wanted to see how small a synth we could make. On both fronts we think Lore is a success - it measures under 3 x 3 inches, and the FM mode gives you access to a whole range of shimmering, grinding, and metallic sounds. Just like with OVUM, we prioritized immediate control and ease of exploration. No understanding of oscillators, wave shapes, or FM synthesis is required to pick it up and start creating interesting and inspiring sound. We think people of all ages, musical abilities, and experience levels are going to love this instrument.

Lore is available now for $79 CAD / $59 USD.

Lep Lumanoise / Crows Electromusic Ovum / Magpie Pedals Wet - A Study of Cronch

video upload by Oscillator Sink

"I'm working on a video about these neat Lep Lumanoise devices, but while I was getting to know them, I ended up with this small set-up that I was finding quite inspiring, so I thought I would record a short performance.

The percussive element is the Lep Monocassa, and I'm routing its internal trigger through a delay to get additional rhythms when required. The drones are the Lep Lumanoise v4 and the Crows Elecromusic Ovum. The Lep Lumamix is bringing everything together, gluing and smooshing the signals in a way that makes each instrument feel interactive with the others as they dance and fight for dominance at the edge of distortion. The Magpie Pedals Wet is on the send of the Lumamix and is vibrating, clanging and resonating along with the other signals - it really is glorious in this setup.

I'll be speaking more about most of the things on the desk soon, but for this one, I'll shut up and let them do the talking.

Adventures in Thyme! - Episode 2 - Transforming Ambience and Drones with the Bastl Thyme+

video upload by Oscillator Sink

Adventures in Thyme!

"It's time for episode 2 of ADVENTURES IN THYME! A short series on the channel where we'll be exploring Bastl's stereo digital tape loop machine through a few different lenses. In this episode we take a look at how we can use Thyme+ to completely transform, re-contextualize and animate a drone (coming from the Crows Electromusic Ovum).

Transparency Notice: Bastl kindly provided the Thyme+ to me for free for the purposes of making video on it. I wasn't otherwise paid, and they have not asked for, nor have they been given any editorial oversight of the content I create."

What is Ovum? (And how might one use it?)

video upload by Oscillator Sink

"Ovum, from Crows Electromusic is an analog oscillator bank containing 5 freely tuneable oscillators. It is a simple instrument suited to drones and ambient, but becomes most interesting (in my opinion) when paired with other instruments. So join me on this calm voyage of discovery as we get to know Ovum and how you might pair it with other instruments.

During development of OVUM we’ve had the pleasure of handing the instrument to people who’ve never touched a synth in their life - and then watch their eyes light up as they discover how easy it is to make strange and beautiful sounds when they’re unconstrained by conventional time signatures and musical scales. We think people of all ages, musical abilities, and experience levels are going to love this instrument.

OVUM is available now for $129 USD.
