A patch to play with the Morphing Terrarium. The XY output is patched to the Linear FM input of the Fritz Teezer through-zero VCO through a VCA to get some dynamic linear FM action going. The Morph X and Morph Y VC inputs are each modulated by the sine wave from two MOTM-390 LFOs, the levels being controlled by external attenuators. A sample and hold varies the MT pitch, as well as controlling the LFO rates.

If this sounds a little like the “Start From Zero” patch, it is similar. Except I used the Teezer and the MT instead of the ZerOscillator and a cycling Serge VCS as the oscillators. The Teezer can be set to almost zero frequency, but there’s no linear fine tuning, so it winds up sitting at 1 or 2 HZ.
