Op-1 recording at reducing speed no altering pitch


i am used to take advantage of lowering the speed of sequncer to get an improvement about timing, but on op1 this is results in an alteration of the pitch of recorded material.
I have tried to set tape speed at 0.5 and pitching instrument +1 octave but this is challenging.
any workaround to just slow down -30% and record without pitch alteration ?

Check your sync setting under the metronome button, unsend the tape from the sequencers.
