L-1 Digital Tuner. Eurorack synthesizer.

Some info via L 1

8HP Digital tuner shows notes in the range 10 octaves .

I don't just srewed a guitar tuner to an Eurorack panel. I modified the circuit, replaced some parts to have correct range. Now it shows notes in the range 10 octaves.

Two sources selectable with switch. Multiples to use a signal further.
A4 button Select A4 frequency in the range 430-450Hz.
ON button. If to hold the button 1 sec, turn the screen off/on. Momentary press select tunning item: Chromatic, Guitar, Bass, Violin, Ukulele. Default position is Chromatic. No need to change.
If no wave at the input or a wave is out of the range, screen will turn off in two minutes. If it happened just press ON button 1 sec to turn the screen on.
Power consumption: V+ 7mA, V- 0mA.

Only assmebled module. No kits.

3x Microbraids Demo Test

Published on May 30, 2017 karlmarxstadt

"This is a quick stoic rythmic improvistation using 3 DIY 'Microbraids' oscillator modules.

The patch is very reduced, but shows some of the possibilities of using braids for percussion, chords and ... well... more percussion :)

Units in the patch:
-Verbos Multistage as Sequencer Triggering all three Modules,
as well as sequencing CV inputs on #1 and #2
-Slight attenuation of CV via Pittsburgh Mixer,
-Audio from all 3 Braids gets mixed into a L1 Mixer and then fed into the Schippmann filter, just to soften the timbre.

Line recording audio with no additional effects.

The module on the left uses a blue OLED display, the two on the right are in white.

I have a friends who builds these. Let him know what you think, if you have any questions, let me know."

L-1 Quad VC Resonant Equalizer

Published on Mar 7, 2017 Perfect Circuit Audio

"The Quad VC Resonant Equalizer from L-1 is a 4CH parametric EQ with full voltage control over each parameter. It can be used as a single quad EQ or as four independent filters. Each channel is complete with resonance switches as well as bandwidth controls. Channels 1 and 4 can be switched from Bandpass filters to Lowpass and Highpass, to provide a full spectrum EQ.

In this patch the output of the Mannequins Just Friends is filtered by the L-1 VC EQ. Each of the 4 bands from the VC EQ is mixed by the Verbos Scan and Pan, which is controlled by envelope generators Triggered by the Malekko Varigate 8+.

Smoke Panel L-1 Synthesizer Quad VCA Module by Paper Products Music

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

This is a eurorack module designed by L-1 Synthesizer and assembled by me. The panel is my own design, produced by Pro-Modular. If it's difficult to tell from the pictures, it's a "smoke" color and only slightly opaque. It is mostly transparent. I have many of these available.

The module itself is a very high quality VCA design based off the THAT2180 VCA. What's especially interesting about this design is it's also a voltage controlled mixer. Channels 1&2 mix, channels 3&4 mix, along with a total mix out and an inverted mix out. Of course, every channel has its own output as well.

More information on the design is here:

"Short sample. Any sequence here, just two LFOs modulate the filter. Frequency modulation gives rhythm, reso modulation gives accent. LP-BP-HP modes. No effects."


"Several saw waves through 2180VCF + bass drum."


"Perfect 5 octaves tracking at filter selfoscillation. Check the sample with a tuner!"
