animated mesh of an icosphere

Nikolaus Gradwohl2018-10-31T02:18:35+00:00

I created a set of splines using the animation nodes vertices-to-spline node and then animated it with a builder modifier in blender

Arduino based Midi Trigger box for analog synths

Nikolaus Gradwohl2018-09-14T07:11:26+00:00

I usually control my volca and the Mother32 via midi and create sequences using Bitwig studio or Sonic Pi but I wanted to use the build in sequencers to create a more hands-on feeling and simplify loop creation while jamming but haven't found a satisfying what to synchronize the sequencers to each other and to my computer

I considered buying a bastl klick - but I would need several of them to control different synths at different clock-rates and I would have to sacrifice several audio outs to control them.

So I build a midi-trigger system using an arduino that allows me to send trigger signals to 4 devices using midi note-on signals. Now I can run the sequencers of my devices at different clock rates allowing me to use longer or shorter sequences or create different rhythms by sending trigger signals with different note lengths to the DFAM. Sort of like a clock-divider on steroids combined with a sequenceable trigger pulse.

Sonic Pi beatslicing livecoding session

Nikolaus Gradwohl2018-06-23T17:47:10+00:00

this is the recording of a SonicPi Livecoding session made from 2 sample loops sliced and rearranged in different ways

for the drum sounds I used a drumloop sliced it into 32 peaces each 1% the length of the original loop. Each click is chosen at random from the ring created by the line command.

n = 32
l = 0.01
s =  line(0, 1, steps: n+1).choose
f = [1,s + l].min

sample "drumloop.wav", beat_stretch: 16, start: s, finish: f

The samples are triggered at a given 16th slot with a changeable probability.

the e-piano loop is played back at different speeds chosen from an array using [1,-1,0.5, -0.5, 0.75, -0.75].choose and placed at a random position in the stereofield using a :pan fx

Welcome Lil Erebus

Nikolaus Gradwohl2018-06-11T19:33:30+00:00

I build the Erebus Lil DIY kit by dreadbox this weekend - after 6 hours of soldering estimated 100000 components on very very tiny solder pads on saturday, I spent 8 hours on sunday searching for the one cold solder joint :-/

But everything is working fine now and here is a first short jam with my new synth - enjoy!

AN Experiment 2018 Test 13 - create mesh

Nikolaus Gradwohl2018-06-04T06:45:42+00:00

For this animation node experiment I created a mesh from scratch only using Nodes. I made a spiral of vertices and projected them onto a sphere. I animated the length of the curve and the radius unsing AnimateFloat-Nodes. Then I added lists of edge- and face indices interating over the vertex list in some nested loops.

AN Experiment 2018 Test 11 - trace vertex

Nikolaus Gradwohl2018-05-29T06:38:55+00:00

For this animation nodes experiment I used a technique for tracing particles or vertices presented by Omar Ahmad on stackexchange that uses python script object to store a list of all the coordinates of the previous frames in a python object - I really like this idea.
