Setting up Korg’s logue SDK

At least during the last decade, Korg became a company which constantly generates “Products that customers love™”. From Legacy collection over Kronos to Minilogue, further to the famous Prologue and finally the Minilogue xd, Korg keeps the market busy.

The recent Minilogue xd borrows an outstanding feature from the Prologues. Users can write their very own custom oscillators and effets. To accomplish that, Korg provides the logue SDK via Github.

It is provided “as is”, with no further support, and is not easy to setup. Fortunately Grischa Ekart provides a couple of tutorial videos, the very first one sharing the essentials to get the SDK up and running. From his video, I’ve extracted the crucial steps:

  • Create a folder where you want to place your SDK. Open a terminal window there.
  • git clone
  • cd logue-sdk/
  • git submodule update –init
  • cd tools
  • cd gcc
  • ./

I got an error message, which did not harm the further process at the moment:
./ line 92: popd: directory stack empty

  • cd ..
  • cd logue-cli
  • ./

I got two error messages, which did not harn the further process at the moment:

./ line 35: pushd: /Users/ce/Development/Korg: No such file or directory
./ line 98: popd: directory stack empty

  • cd ./logue-cli-osx-0.07-2b/
  • ./logue-cli
    • The logue-cli is not necessarily required, since one can transfer the files to the minilogue xd via the graphical librarian.

  • cd ..
  • cd ..
  • cd ..
  • cd platform
  • cd minilogue-xd
  • cd demos
  • cd waves
  • make
  • ls waves.waves.mnlgxdunit

The resulting file waves.mnlgxdunit is a Zip-archive. In my case, the Minilogue xd did not accept this file:

I fixed this by lowering the API version in manifest.json:

  • Change “api” : “1.1-0” to “api” : “1.0-0”
  • Save and close
  • make

Now the file is accepted by the Minilogue xd and works as expected :) .

Thanks a whole bunch to Grischa Ekart for figuring the necessary steps out.

Diakritische Zeichen in Unicode

Auch in Unicode gibt es mehrere Möglichkeiten, diakritische Zeichen darzustellen. Stark vereinfacht ausgedrückt kann ein Zeichen als selbstständiges Zeichen (»Ich bin ein Ä«, Normalization Form C, abgekürzt NFC) oder als zusammengesetztes Zeichen (»Ich bin ein A mit zwei Punkten darüber«, Normalization Form D, abgekürzt NFD) ausgedrückt werden.

Ich nutze ein Python-Skript auf Mac OS X, um automatisiert aus Dateinamen Tags für Ogg-Vorbis-Dateien zu generieren. Im Dateinamen von OS X liegen die diakritischen Zeichen als NFD vor. Um die Zeichenkette in NFC zu überführen, nutze ich folgenden Aufruf:

filenameNFC = unicodedata.normalize("NFC", filenameNFD.decode("utf-8"))
