Hello blog!


It has been at least about 4 years since I renovated my blog. The time has come to let the old wordpress blog (here) die away. This time, the content is more focused on my research in the music information retrieval field and my other work in software development, new technologies and music. If interested, my old blog is still available at…

The XB-2 Main Board

Fixing Hammond XB-2


A few weeks ago Dejan and I began our work on Hammond XB-2 again. The current problem can be heard here: We tracked the problem back to the static RAMs, which was also mentioned as a solution in one of the comments on this similar youtube video. We opened the keyboard and took out the main board. As you can…

Hammond XB-2 and Roland VK-7

Big boys … new toys: Roland VK-7 and Hammond XB-2


Last week I bought two aswesome instruments  – a Roland VK-7 and Hammond XB-2. The latter unfortunately has the MUSE chip failure. I tested it few months ago and shot this video. I still haven’t given up on it. I checked some options including the XB2-kit. The kit is however more expensive than a fully functional keyboard (and the XB-2…

Friction Drum - Lončeni Bas

MusicTechFest – Friction Drum


On Saturday Karmen and Miha presented the electric version of the Friction Drum instrument (a folk instrument well known in Slovenija, as well as other parts of the world) at Music Tech Fest in Ljubljana. The presentation was awesome, as well as the demo of them playing. I managed to make a few pics with my mobile phone (thus, the quality) and a…

MusicTechFest – Compositional hierarchical model


Today, Manca, Luka and I presented the Compositional hierarchical model at the Music of Science session at Music Tech Fest in Ljubljana. As a part of his undergraduate degree, Luka built an awesome transcription editor which uses the CHM as classifier. It will probably never reach version 1.0 since the “ideas” stack grows exponentially. However, we are planning on providing a freeware…

Crumar T1 Organiser

Crumar – we’re almost there!


Z Dejanom sva uspela identificirati še zadnji problem nedelovanja in šumenja orgel. Tokrat je bil problem v slabih kontaktih na ploščici, kjer se nahaja oscilator, kar je posledično vplivalo na več ali manj ves output. Najin zadnji podvig bo reševanje ene in edine nedelujoče tipke. Sama tipka niti ne moti, če je bas del vklopljen (v tem primeru se zvok…
