[Guest blog post by Robert Manzke<\/a> alias rma31<\/a>]<\/p>\n\n\n\n

Hi, my name is Robert, some 6 years back I have founded the academic working group “Creative Technologies AG”<\/a> (CTAG) at Kiel University of Applied Sciences in Germany<\/a>.
In the domain of Audio, we engage students and form international collaborations.
Our focus is music technology and production, sound synthesis and design and adjacent areas such as electronics, computer graphics, algorithms, related hard- and software, maker technologies, human machine interaction, immersive art and media and so forth…<\/p>\n\n\n\n

Also, I got my first Freesound t-shirt on June 2nd 2009 and have always been a great fan of the Freesound idea, to create a social and open platform for sounds and its use in science and education.<\/p>\n\n\n\n

Since the existence of CTAG, there have been several student teams involved with the Freesound API to interact with the sound data base. Most notable results include the Beaglebone single board computer based sampler “Beagle Boom” <\/a> and, very recently, the Eurorack sample streaming module “CTAG Str?mpler”<\/a>:<\/p>\n\n\n\n

CTAG Str?mpler<\/a> (half streamer, half sampler therefore “Str?mpler”, which is close to the German word “Strampler” meaning romper suit) is an electronic sound synthesis module designed for Eurorack modular synthesizers.
Most importantly, it has internet access with connectivity to the Freesound API, making the Freesound sound data base accessible through hardware. One can download sounds to the module’s SD-card and play them back as two separate voices.
Typical parameters such as pitch and amplitude can be influenced, just like one would do with a sampler. It includes a comprehensive control voltage (CV) matrix, where external CV signals can modulate various sound parameters. Some basic effects such as a stereo delay and low\/highpass filters are implemented as well. <\/p>\n\n\n\n

The firmware and the DIY hardware design are entirely open source and available on Github<\/a>. CTAG is currently looking for collaborators to further develop the Str?mpler. One highly desired feature would be the ability to sample your own sounds within your Eurorack setup with Str?mpler and share them instantly on Freesound, actively contributing to the sound data base. More details can be found on hackaday<\/a> and the projects web-page<\/a>. <\/p>\n\n\n\n
