NAMM 2014: Waldorf 2-pole

Waldorf introduced a new analog filter, the 2-pole at this year’s NAMM show.


Those of us who spend time with analog synthesis are quite used to all sorts of complex filter topologies, most of which have at least four poles. So a two-pole filter seems a bit simple by comparison. But Waldorf is known for taking simple concepts and turning them into complete instruments. The 2-pole includes low-pass, band-pass, and high-pass elements, and also includes drive and rectify settings. It also includes its own envelope and LFO, as well as live triggering capabilities.

You can see a full demo of the Waldorf 2-pole in this video:

DSI Evolver legal again in Kansas public schools

After the recent electoral defeats of Creationists on the Kansas school board, students are now free again to use the Evolver synthesizer from Dave Smith Instruments. Was the Evolver an unintended victim of the continuing assault on the theory of evolution and scientific reason, or part of an orchestrated effort to eliminate all electronic music in Kansas except for the DX7 electric piano patch used by wedding and bar-mitzvah bands?

Speaking of music spawned by the devil, I have been experimenting a lot lately with the use of feedback as the primary sound source for the filters instead of the starndard oscillators. The instability combined with the filters and multiple conversions between analog and digital in the signal path make for some very interesting results. I have posted an example here for your listening pleasure. Be forwarned, there are a lot of harsh high frequencies in this example, though the MP3 compression does help soften them a bit. Enjoy!
