Smog/Knot ETA

Post by toneburst » Tue Oct 16, 2018 10:24 am

Any clues on when the new redesigned MI modules, Smog and Knots might see a PCB + Panel release?

They look great!

Hey, they are available now on www.pushermanproductions.com, there are buttons to the store page for every module on the www.antumbra.eu website too.

I just picked up Antumbra Smog. It's great fun. I appreciate the build quality, as well as its compact size because my rack is tiny.

Here's a quick 60 second demo. In the video, Smog's pitch is controlled by the contour output of the 0-Coast (by way of a VCA, triggered by Monome Earthsea). Increasing the 0-Coast's delay causes the contour to change and brings interesting reverb effects.

Hi antumbra, hi pwenzel :)

is there a build guide online? Any programing skills necessary?

btw: i have ordered one on pusherman!

@Radium I bought mine pre-built on Reverb. I found some build documentation here:

The documentation on the site tells not enough :/ only part list! maybe antumbra can tell me more how to do :)

Cheers ;)

Programming the Arm device

Post by merlin » Mon Jan 21, 2019 7:25 am

I'm interested in building this module but not sure how you would programme the Arm device. Do you follow the instructions on the Mutable Instruments site (see below) and does this method work for the initial device programming?

"Firmware update procedure

Unplug all CV inputs/outputs from the module. Connect the output of your audio interface/sound card to the IN L input. Power on your modular system with the FREEZE push-button pressed. The FREEZE LED will blink.

Make sure that no additional sound (such as email notification sounds, background music etc.) from your computer will be played during the procedure. Make sure that your speakers/monitors are not connected to your audio interface - the noises emitted during the procedure are aggressive and can harm your hearing. On non-studio audio equipment (for example the line output from a desktop computer), you might have to turn up the gain to the maximum.

When you are all set, play the firmware update file into the module. While the module receives data, the bargraph will show the signal level. Signal reception is optimal when two or three LEDs are lit. You can use the IN GAIN knob to boost or reduce the gain. When the end of the audio file is reached, the module automatically restarts - if it is not the case, please retry the procedure.

In case the signal level is too weak, the LEDs will blink in red. Press the FREEZE push-button and retry with a higher gain. If this does not help, please retry the procedure from another computer/audio interface, and make sure that no piece of equipment (equalizer, FX processor) is inserted in the signal chain.
"

Regards,

Karl

No - not on a bare board with no bootloader. You would need a programmer eg stlinkv2. Try googling how to program stm32 MCUs. (If you look in the hacking resources section of the mutable website for each module it also tells you)

Just thought - I’ve written up how to do it on my blog along with my guitar and modular builds

DIY Guitars

Look under modular->notes and modular->diy modules

Hello All

I've been lurking for a while - putting together a mini rack, and think I could populate it with mostly Antumbra modules.

Looking at the BOM for Smog, there seems to be a Murata capacitor that is EOL - GRM188R71E104JA01J - can anyone suggest a replacement?

Does anyone know where Smog can be bought prebuilt or in a kit in the EU?

How about GCM188R91E104JA37D for alternative ?
They are different only on Maximum Operating Temperature, so it should be replaced.
