Micro Synth Signal Levels

[soffa]

Could anyone help me with what a reasonable signal level is coming out of the first stages of an EH Micro Synth? (Points 2,4,5 on the schematic.) I´ve almost got my clone working (filters sweep and everything  ) but the signal levels are very different coming out of the various sections. (octave, suboctave...) It seems like the sections that involve an OTA are much quieter than the others, which makes me think that I have the input gain trimmer up too high? I sure my problem is a lack of understanding of OTAs! Can someone help me with a reasonable signal level to be feeding to the filter stage?

Thanks!
