I have been wondering about the word "Eigentakt" Purifi uses and searched for it on the web. This came up.

Beforehand I thought the Danes borrowed this German name for marketing purposes. It has robust ring to it, well at least it sounds very high-tech to me. But after reading the explanation I almost hit my head because I should have understood it right away. Eignentakt in Icelandic would be Eigin-taktur. Smilar eh? And once I saw this it's very transparent and self explanatory. Eigin means "own" and takt or taktur means "beat" own-beat, self oscillating ...
Now after making this totally off topic comment I need another beer! Cheers!
Ps; I agree with the OP, Purifi Eigentakt is on the bucket list, but we NEED big VU meters to go with it!
