SFZ to Multisample converter

Nikolaus Gradwohl2014-11-06T06:11:40+01:00

I have a lot of sfz samples on my harddisk but unfortunately the only sample format the internal sampler from bitwig studio can use is the built in multisample format. I played a bit with the fileformat and found that it´s a zip-container with all the wav-files and a xml file that describes how to map the samples to keyboard regions. Thats very similar to the structure of a sfz sample so I wrote a simple converter script in java that can be used to convert sfz to multisamples.

The program is far from perfect and I consider it more as a prototype than a final program - so be warned. I also haven´t implemented more advanced features like velocity zones or groups yet.

You can download the sourcecode from my github repository at


or a compiled version here: Sfz2Multisample-1.0-SNAPSHOT.jar

to use it open a terminal and start the program with the filename of the sfz file as a parameter

java -jar Sfz2Multisample-1.0-SNAPSHOT.jar sfzfilename.sfz

the program then creates a multisample with the same name.

I made a new version of my metabubbles animation this time in red/orange/yellow - becaus helloween

growing along an animated curve

Nikolaus Gradwohl2014-10-30T06:22:58+01:00

For this animation I used an array modifier and made it follow a curve. To make things more interesting I added some shapekeys to the curve and added a noise modifier to the animation

I've been drawing again



Nikolaus Gradwohl2014-10-28T05:57:29+01:00

For this animation I used a particle system that uses a metaball as particle object. The metaball system has a material with an SSS shader. The only light source is placed above the particle emitter

I created a new playlist on soundcloud today, featuring some of my songs.

black particles

Nikolaus Gradwohl2014-10-24T06:50:16+02:00

I made a new simple animation using the blender particle system. I animated the particle emitter along a bezier curve, added a no physics particle set and also clicked the show dead particles to prevent them from dissapearing. For the light setup I used a sky node for the "world" and a plane with an emission material on the upper right.

diffuse freeze

Nikolaus Gradwohl2014-10-13T07:39:15+02:00

For this animation I used an animated material that changes the diffuse parameter of a glass material in cycles
