Uploading sounds to the Volca Sample on the Commandline

Nikolaus Gradwohl2015-02-03T15:27:14+01:00

Korg released a SDK for the Volca Sample in november 2014. The SDK contains a bunch of libraries and header files to develop tools that comunicate with a Volca Sample. Besides all that it also contains an example program compiled for linux, macos and windows that can be used to upload samples to the Volca on the commandline.

Convert the sample you want to upload to a stereo, 16 bit, 31.25 kHz WAV-file using the sample editor of your choice (or convert it using sox)

download the volca sdk from their github repository (click on the source tab)

unzip the package and go to the example folder in the volca sdk. Enter the directory for your operating system (linux in my case)

now you can use the makesyro_gnulinux.sh script to convert the audio file and choose the slot on the Volca Sample

makesyro_gnulinux.sh -n 99 test.wav

connect the output of your soundcard to the sync-in socket of your Volca and start playing back the syro_stream.wav

the linux shell script also has an option to start the playback automatically

on macos or windows the provided scripts are a little less versatile that the linux version to change the sample or the slot to upload you have to edit the script and change the values in the header section of the file.

my volca trio just turned into a volca quartet

I think I know what I will do this weekend :-)

I've drawn a quick sketch of my volca synths while waiting for a download. Using black ink and Copic markers

new Song - Gap Between Idea and Action

Nikolaus Gradwohl2015-01-07T05:28:54+01:00

This track evolved from a recorded volca bass jam session. Except for the bass line all synths are softsynths from bitwig-studio

Volca Jam 2014-12-12

Nikolaus Gradwohl2014-12-12T20:59:38+01:00

I recorded a new jam session using my volcas, my kaospad mini, bitwig-studio and my launchpad.

The bass sequence was created using the stepsequencer in bitwig and is played on the volca keys. (dont let your self fool by the name, the keys can make really awesome basslines)

The arpegios are created using the volca bass and the kaospad mini. I used the bitwig arpeggio note effect and enter the notes using the launchpad.

Passive Mixer for mv Volcas

Nikolaus Gradwohl2014-12-05T06:26:54+01:00

I have added a new gadget to my studio - eeeehm - desk, a passive mini mixer with 3 inputs for my volca synths. I´ve soldered together 4 mini 3.5 cm stereo jacks, 3 stereo potentiometers and 6 10kOhm resistors. Unfortunately I only had potentiometers laying around that need to be soldered to a circuit board to gain stability and they where really wobbly with my rats-nest cabling. So I used some sugru to keep them in place.

I also noticed that components that are upside down have their left and right side inverted :-/ so my knobs turn in the wrong direction now ... (just as a warning to others)

volca+bitwig - stepdup

Nikolaus Gradwohl2014-10-10T20:44:44+02:00

For this session I used the novation launchpad step sequencer for bitwig to create sequences for my volca synths (hence the name)

broken metaballs

Nikolaus Gradwohl2014-09-15T06:01:38+02:00

For this animation I used the cell fracture addon on a mesh created from a bunch of metaballs.

To add a bit more drama, I created a soundtrack based on the "inception braam" sample I made using my volca bass

Sax Loop

Nikolaus Gradwohl2014-09-09T03:56:28+02:00

This is a recording of a bitwig/launchpad/volca jam session that evolved around a saxophone sample that comes with bitwig. I also intended to record a video of the session but unfortunately I forgot to check the batteries of my camera so I only recorded the first 2 seconds :-/
