"Deft Audio Luma 1 Drum Computer. This is from the first run of 100 units from Deft Audio. Serial number 073. An incredible and faithful reproduction of the Linn LM1 brought back to life by Joe Britt. It has the same DACs and filters, but has a few new features to make life easier such as the ability to load your own samples via USB. Absolutely beautifully built and sounds completely authentic as you would expect from Deft Audio. Also comes with a rather huge protective case that will survive anything."

Here's my rundown of Knobcon 2025 'Synthmania XIII', with coverage of performances, new gear and the experience of actually getting to play there with Cowboy Ben Alman a.k.a @TheEntireRobot . Thanks to Suite And Tie Guy for letting us play on Friday, and Daniel Kushner for getting us on Saturday afternoon’s festivities with support from the whole Golden Shrimp Guild. What a blast! Here are some handy links:
"Our friends at Deftaudio present the Lumaµ (Luma-mu), a single voice version of their Luma 1 LinnDrum recreation in Eurorack format. It uses the same discrete electronics and EEPROMs as the original, with various CV options that allow one to use it as a traditional drum-machine or go in different creative directions.
"This tutorial is on the latest integration of Luma-mu and Teensy 4.1 MIDI interface to drive Luma-mu clock input directly. This not only gives you the precise tuning of Luma-mu for perfect pitch stability but radically simplifies the integration in modular setup and makes it possible to use as a part of the polyphonic synth setup.
"Let's dive into the magic of Linn LM-1 Hi Hat. Will look on how it was created and make our own bank for Luma-mu. This continues a tutorial series of Luma-mu Eurorack module.
"The new version of http://luma.tools introduces direct support for reading and writing PicoROM EPROM emulator which makes it simple to use with Luma-mu for transferring sounds. You no longer need to install extra software for PicoROM, everything is running in Web browser (Chrome) and it's cross-platform."
"All drum sounds in this demo come straight from the Deft Audio Luma-mu module—a real Linn LM-1 voice in Eurorack form.
No samples, no microcontrollers—just direct hardware playback, multitracked and sequenced for maximum punch.
The Luma-mu delivers that classic ‘80s snap and swing, but with CV control and modular flexibility.
If you’re into vintage drum sounds with analog immediacy, this one’s worth checking out."
"Making your own sounds for Luma-mu with https://luma.tools/ - Web-based sound editor for Luma-1 and Luma-mu."
"After launching the successful Luma-1 project, which is a precise recreation of the legendary Linn LM-1 with extended feature set, we’re announcing the beginning of shipping Luma-mu.
Luma-mu is a 10HP Eurorack module, essentially a single drum channel of Luma-1 which holds multiple sounds in its ROM. It plays samples digitally without microcontroller or software used, which guarantees the lowest latency and highest response of its 8-bit mu-Law DAC. It’s perfect for Luma-1 expansion or standalone operation.
Luma-mu feature set:
8-bit mu-law EPROM playback, exact copy of LM-1/Luma-1 channel
Removable EPROMs with 8 sounds on each, 16KB each (~1.5sec/ea)
True digital playback with no microcontroller or software involved, order of nanoseconds response time to the first sample
CV control for sound select allows playing various sounds at each step
CV control for Pitch and Dynamics
Gate control for Reset, Pause and sample Trigger
Can be clocked externally
Ability to play one shot samples or looped sounds to use it with perfectly looped waveforms as a wave oscillator
Comes with a software to make your own EPROMs
EPROM is accessible from the front with optional Luma-mu Reacharound extender module
Eurorack 10HP, 50mm depth
Luma-mu is available at https://www.deftaudio.com/
MSRP is $279."
"A compact yet powerful MIDI and audio hub featuring 8x14 MIDI routing, 4 audio outs, 6 trigger/sync outputs, and USB connectivity. Built on the lightning-fast 600MHz Teensy 4.1 microcontroller, it supports standalone operation and deep customization through open-source hardware and software. Perfect for synth enthusiasts, modular setups, and custom audio projects.
Comes as a fully assembled 1U unit, DIY kit, enclosure, or just PCBs.
Available at www.deftaudio.com or https://www.tindie.com/stores/deftaudio/"
"Luma-1 is an authentic recreation of the iconic LM-1, originally designed by Roger Linn in 1979 and now brought back by Joe Britt (check the creation story at Roger’s site). Fully recreating the original design of the LM-1, it utilizes the same audio path with the original vintage DACs and filters, runs the original LM-1 software, and adds a secondary modern processor for adding highly desirable features like loadable sounds, USB connectivity(USB MIDI Client and Host), MIDI and more."
"An introduction to the Luma 1 from Deft Audio, a circuit-accurate reimplementation of Roger Linn's legendary LinnDrum. They are also introducing a Eurorack single-voice version of the Luma 1, the Luma μ ("Luma mu"). In addition to the original features of the LinnDrum, there are some enhancements including uploading ones own samples, and even editing via a online web app that connects directly to the instrument."
"At NAMM 2025, we caught up with Joe from Deft Audio, who shared insights into their latest product, the *LumaOne*. Joe explained that LumaOne is a meticulous recreation of the iconic LM-1 drum machine. Its original was notably influential in the '80s music scene, appearing in tracks by Human League and Prince. However, with only 500 units produced, it became difficult to find. Joe recounted his journey to revive its legacy, which began during the COVID period when a rare LM-1 came into his possession, allowing him to create an accurate clone using vintage components.
LumaOne combines the classic sound of the '80s with modern enhancements like LumaTools for custom sound editing and MIDI integration. Joe also introduced Luma-Mu, a Eurorack module derived from the LM-1's voice architecture, bringing its unique sound into the modular world. Both products offer hand-built craftsmanship with LumaOne retailing at $4,500."
"Big update on Luma-1 development status, new features added and enabled in the 0.943 firmware release. Also talking about Luma.tools - the online editor, and showing how to use it.
"Playing LM1 patterns on Luma-1 live, no post processing. Yamaha DMP11 used as the FX for delay and Gated Verb.
