Processing and Blender Sound Visualizer for Magical Dreams

Nikolaus Gradwohl2017-09-29T07:51:40+02:00

I finally managed to finish a project where I could combine most of the tools I love and use. I created a processing sketch to visualize the stereo correlation of my song "Magical Dreams", exported the frames and used blender to create an animated highfield based on the brightness of the images. Then I rendered these frames and combined them to a video with the original track exported from bitwig.

Hmmm ... maybe a bit more complicated than needed, but that's one of advantage of a hobby project - you don't have to justify yourself for inefficient processes and toy around as long as you want to :-)

new Song: Still Awake

Nikolaus Gradwohl2017-09-27T07:14:31+02:00

I finally found the time to sit down and arrange and mix one of the song fragments that are waiting on my harddisk. I'm currenly very tired after a week full of nightshifts, overtime and bughunting but I'm still awake ... (ok not the best song title ever, but my thoughts are still a bit fuzzy - did I mention sleep deprivation?)

How to modulate Midi-CC values in Bitwig Studio

Nikolaus Gradwohl2017-09-15T06:26:53+02:00

to make a synth line played on a hardware synth more interesting you can modulate some parameters like filter cutoff, decay time, etc using a midi cc value. This can be done using bitwig studio by either using a automation lane sending the cc value or by using the cc device.

To use an automation lane simply click on the "Show automation lane" icon and select the controller value you want to send in the "midi" section

bitwig cc lfo modulation

then draw the cc values in the lane you just created. I used this technique in my latest song to create the filter cutoff of the highpass filter on my moog mother32 for example

bitwig cc lfo modulation

The second version uses the "Midi CC" device. With this device you can use bitwig's brilliant modulation sources to create the cc you want do send. You could combine several modulation sources like lfos step sequencers etc to influence your sounds.

blender denoiser experiment: subsurface shader

Nikolaus Gradwohl2017-09-11T06:05:41+02:00

I made a new Blender Experiment to explore the possibilities and limits of the new blender denoise function. This time I tested the denoiser on a material using a subsurface shader node in combination with a pretty low sample number, because the subsurface node in a material creates very noisy images and increases render time a lot

For this experiment I creatd a simple is-sphere and added a voronoi texture as the displacement texture to make the object a bit more interesting. The material was created using the new cycles Principled BSDF node.

microdisplacement denoise test

Nikolaus Gradwohl2017-09-05T05:54:43+02:00

I wanted to test the limits of the new blender denoise function so I used a very detailed texture with lots of sharp edges for microdisplacement.

SonicPI + Volca Jam - Behind the Scenes

Nikolaus Gradwohl2017-08-28T05:30:30+02:00

This weekend I posted a video of a SonicPi and Volca livecoding jam where I used the new midi functions of SonicPi 3 to control my synths. In this post I describe the setup I used and explain the code a little bit.

SonicPI + Volca Jam

Nikolaus Gradwohl2017-08-26T19:34:38+02:00

I recorded a SonicPI live jam exploring the new midi functionality. I used my Volca Keys, Volca Bass and Volca Sample for the recording.

blender 2.79 denoise test

Nikolaus Gradwohl2017-08-17T10:34:03+02:00

I used this render to test the new denoise function in blender - I rendered the animation with 24 samples.

you can download the blend file here - to run it you have to use a blender 2.79 build, the denoiser is not available in 2.78.

blender dynamicpaint displacement

Nikolaus Gradwohl2017-08-09T07:24:39+02:00

For this animation I added a dynamicpaint canvas to a plane and used an icosphere as a particle instance object and the dynamicpaint brush. I added a second inivisible plane below the canvas to act as a obstacle for the particles.

Texture cuts

I animated the turbulence and scale factors of a texture in blender and used it as a displacement map in cycles
