Hello Group, i'm new here. I need full calibration instructions for my Zero, please. unfortunately i got never an answer from Cynthia. Is there no Trimmer to calibrate the Morph ? thanks, H.C.

Howdy! Sorry I missed your email, I'm bouncing back and forth a lot lately between a Mac and a Windows machine, and in this odd process, I occasionally miss a message now and then. > Is there no Trimmer to calibrate the Morph ? Yes, in the FILES section of this user Yahoo Group: The Cyndustries List, you will find Zeroscillator Calibration Procedures listed as a free pdf file. http://launch.groups.yahoo.com/group/The_Cyndustries_List/files/ You Mention "Morph" Calibration specifically, and while there is no Morph Calibration per se, I suggest that with the Range, Bias, and Thru-Zero switches in the up position, you first take the big ZO Tuning Knob down to rock bottom and leave it there for 20 minutes before adjusting the low frequency symmetry. This is always the first thing to do - because all the other adjustments are based on it. Next check your Sawtooth waves for phase error and remove the kink in the sawtooth. If the RIGHT side of the module Morph Outputs are acting strange, (but the LEFT) are ok, then adjust the QUADRATURE Trimpot and play, "pin the top on the mountain". Please Note: The Morph Scale (tick marks) shown surrounding the pot are iconically different than the actual oscilloscope waveforms obtained. (In other words, the front panel legends printed around the morph knobs do not show exactly where the morphing occurs throughout the rotation of the knob). The morphing occurs, but not at the points in the knobs rotation as shown on the panel... We tried and tried to bend the nonlinearity of the morph function to our will in order to more closely match the knob graphics, but the universe just laughed back at us silly humans and told us we were lucky to have such a smooth continuous three wave morph function in the first place, so we listened!

Thanks for answers Berni and Cynthia, Cynthia i will mail you from this mailaccount: modulardudeldidum1[at]hispeed[dot][ch] there is some unclarity i better mail direct to you.
