Not your average frequency shifter. This is a one off, custom built, nothing but tubes inside, and it sounds great. You may have heard about Mr. Sala's Mixtur-Trautonium, which is a really nice vintage synth, but his frequency shifter is just as interesting.
Here's a little trick for hardware synth owners who want to try out xenharmonics. Even if your synth doesn't have proper tuning capabilities, you might be able to get some EDO's (equal divisions of the octave, or equal temperaments) out of it. This trick works if your synth has an option called pitch slope or pitch keyfollow.
Philosophical history has not been kind to musical sensibilities. The orthodox history of Greek thought has been de-musicalised. Because of this, we have been tought all kinds of philosophical nonsense, especially when it comes to the Pre-Socratics. But the 'lost' musical heritage is restored by philosopher-musician Siemen Terpstra.
When the French one-man company Twisted Electrons shipped it's first batch of SID-based TherapSid synths in the fall of 2014, some users experienced 'stuck notes' and MIDI-trouble but Alex seemed to react swiftly and accurately. And so, by january 2015 the € 399,- for a TherapSid (with 6581 chip, or € 333,- without) seemed a justifiable investment. Long story short: the monster has matured quite a bit.
The Dubbhism blog uses a Google service, called Blogger.com. We also use Facebook, Google Search, some i-devices etc. The companies behind these products are ~ in Rastafarian speak ~ 100% Babylonian. Part of the international 'military-industrial complex'.
If you want to use analog synths/oscillators for xenharmonic music, there are MIDI-based options like the H-Pi Tuningbox, or the more advanced Silent Way soft/hardware. And there are modules like the Analogue Systems RS-130. Or you could also try a hack: maybe it's possible to hard sync your hardware with software-generated audio.
Transformer 1.0 is a new tool for xenharmonic experrymentation, developed by Dynamic Tonality. Explore tuning~timbre relations using powerful new tricks, based on Bill Sethares' theories. Features like morphing between tunings are not very mainstream, but the live input can retune an incoming signal to any tuning. A great new toy!
This looks like it's going to be a solid documentary about Don Buchla and his 'West-Coast' synth-design philosophy. Fully financed (with a grant and on Kickstarter), Oscar-nominated filmmaker Connie Field should be able to produce the documentary that is 'long overdue'.
