<!-- SC_OFF --><div class="md"><p>Anybody have success performing the Poly D <a href="https://mediadl.musictribe.com/media/PLM/data/docs/P0D9J/User-Support-Bulletin_POLY-D_Oscillator-Calibration.pdf">calibration procedure</a>? I noticed the the tuning was a little off on the lower and higher octaves of my Poly D so I tried it, but now just the OSC 4 range is off.</p> <p>​</p> <p>C3 when played with OSC 1 - 3 each have a ± 5 ct difference across the octave range from 32' to 2' while OSC 4 is ± 15 ct.</p> <p>​</p> <p>All seems fine during the procedure up until the last two steps where it becomes increasingly difficult to hear the offset between the two OSC octave ranges when increasing the distance between the two oscillators (e. g. OSC 1 Range = 2', OSC 2 Range = 16'
. At this point I just adjust the OSC SCALE while observing the tuner until the pitch of OSC 2 matches OSC 1. I'm assuming this is the issue?</p> <p>​</p> <p>Any advice?</p> </div><!-- SC_ON --> submitted by <a href="https://www.reddit.com/user/Raynoldo"> /u/Raynoldo </a> <br/> <span><a href="https://www.reddit.com/r/synthesizers/comments/11n92vo/poly_d_trouble_calibrating_osc_4_range/">[link]</a></span> <span><a href="https://www.reddit.com/r/synthesizers/comments/11n92vo/poly_d_trouble_calibrating_osc_4_range/">[comments]</a></span>
