Are you using the reset on the a160?
take the last pulse you want in your rythmic cycle and send it to the reset
input,this should keep
everything in sync...(also with the lfo are you using the rising edge or
falling edge of wave X
you can also rest the lfo duty cycle on the a145 this will tightn thongs up
also...
I have been using the 160/161 dividers for months now and have no timing
problems
sxcept for a few micro-volts of bleed between adj. outputt sof the 160....
