A Bitwig-Studio Controller Script for Yamaha MX49 and MX61 (Version2)

Nikolaus Gradwohl2016-10-20T07:51:25+02:00

I made an update to my bitwig mx49/61 controller script. I finally worked out how the cubase plugin controlls the text that is displayed on the lcd by tracing through huge piles of captured systex messages using a hex editor.

The new version can be Downloaded on my github page

to install it unzip the files to the "Bitwig Studio/Controller Script"-Folder

Now the script displays the name of the current device when you switch it.

Then the labels of the macro knobs are shown in the display. If a macro is unassigned the knob is shown as "disabled" on the display

bitwig device

mx61 display

bitwig device

mx61 display

as in the previous version I have

mapped the 4 knobs to macro 1-4 on page 1

to macro 5-8 on page 2

and to volume, pan, send1 and send2 of the selected channel on page 3

"AddInst Track" creates a new Instrument Track

and "VSTi Window" opens the device browser.

Have fun!

DNA Nucleotides

I finally found the time to install and test blender 2.78. To test it I modeled the DNA nucleotides adenine, tyhmine, guanine and cytosine

Volca Beat Snare Mod

Nikolaus Gradwohl2016-10-10T05:04:59+02:00

After considering it for ages I finally dared to mod my volca beat and solder a capacitor on the (in)famous C78 solder point, to fix the snare sound.

volca snare mod

The solder pads are REALLY tiny and solding smd stuff is WAAAAY outside my comfort-zone, but it was totaly worth it. The snare sounds a lot more 808-ty and I really like it.

Unfortunately I forgot to shorten the wires on the capacitor as you can see in the photo, so I used a bit of tape to prevent the wires from shorting something on the board (and I will absolutely not unsolder and resolder it :-) )

A detailed description how to mod the volca beat can be found on hackaday at

blockchain link-collection

Nikolaus Gradwohl2016-10-06T06:43:27+02:00


Here is another link collection I have created. This time I collected some links, articles and examples about crypto currencies and other blockchain based technologies.



Bitcoin is the mother of all blockchain based currencies and was invented in 2009 by someone who is using the pseudonym Satoshi Nakatomo


Some introductional articles about bitcoin can be found where https://bitcoin.org/en/bitcoin-for-individuals http://www.coindesk.com/information/

To use bitcoins you need a bitcoin wallet. There is a list of wallets on bitcoin.org that might help you choose the right one https://bitcoin.org/en/choose-your-wallet

And here is a link to the Original paper from 2009 written by Satoshi Nakatomo that started it all https://bitcoin.org/bitcoin.pdf

Javascript and Typescript link-collection

Nikolaus Gradwohl2016-09-13T05:30:56+02:00

javascript link collection

I have used javascript a lot on the client side as an addition for various backend frameworks but I never used it for full stack development. In the last few monthts I used angular2, node.js and express in some POCs and and smaller pirvate web applications - Here are some of the links I found helpful.


I used mainly angular2 and typescript for my frontends. I looked at various other frameworks, but this is what I liked the most.



I really like the hero tutorial by the angular2 team. https://angular.io/docs/ts/latest/tutorial/


since angular2 recommends typescript I started learning it - if you have used an object oriented language like java before, you will feel at home very fast. https://www.typescriptlang.org/

a nice tutorial on how to wirte an angular2 component in typescript https://toddmotto.com/creating-your-first-angular-2-component

How to write a tab-bar in angular2 using typescript http://blog.thoughtram.io/angular/2015/04/09/developing-a-tabs-component-in-angular-2.html


Angular uses rxjs components like Observable in some components

https://reactcommunity.org/ https://gist.github.com/staltz/868e7e9bc2a7b8c1f754


I used bootstrap 3 to style my frontend. I really like this framework, it surely doesn't solve all your designers need but it helps to get a decent looking frontend fast http://getbootstrap.com/

You can also style file-upload buttons https://www.abeautifulsite.net/whipping-file-inputs-into-shape-with-bootstrap-3

Prism is a nice framework for code highlighting in javascript http://prismjs.com/index.html

On creating and collecting phases

Nikolaus Gradwohl2016-09-08T05:25:37+02:00

As you might have noticed, I haven' t written many blog posts in the last few weeks. I usually write posts when I have created something and want to share what ever I have created or explored, how I did it and sometimes even what materials I used and how I did it. But lately I didn't feel like creating at all - hence no blog posts. This situation started to frustrate me and so I started to analyze what has changed and I came to the conclusion that in fact nothing has changed - I am still trying to learn stuff about new topics. What has changed is that I do collect information, material, impressions, references, ideas currently instead of using them up. I always have cycled through phases of creating and collecting - the only thing that really has changed is that I forgot to balance these phases and I got further into the collection than usual.

So to keep this blog from drying up and to bootstrap myself into a more creating mode I will start write posts with collections of links, books I've read, references I collected, topics that interest me and short random thoughts on topics I want to explore further.

In a way this is similar to the experiment series I've done for blender or processing in the past

animation node cube cluster

Nikolaus Gradwohl2016-07-27T07:16:36+02:00

For this experiment I morphed a cluster of random locations into the mesh of a cube using the animation node addon for blender. The mesh of the cube is then turned into a group of splines using the "find close vertices node" and the "Splines from Edges" node.

animation node rotation

Nikolaus Gradwohl2016-07-19T06:56:24+02:00

For this animation I played with the rotation-wiggle node of the AN-addon in blender. To fade the wiggling rotation in and out I used an animation rotation node and a delay
