Because the TOG can't produce equal 12th root of 2 temperaments at all its dividers, this offset resulted in dissimilar scaling offsets per semitone with both ranks engaged. With pitch modulation, it produced a richer string ensemble chorus effect and deviated the waveshapes of each rank. The cent difference of ranks when a key was depressed was not uniform between keys, the largest being ~3.3 cents. This gave the Polymoog an organic sound quality and probably prevented dividers from syncing up.</span></div></blockquote></div><br><div>Ha that is pure genius!</div><div><br></div><div>Non-uniformity of detuning between keys - that's a very real world "acoustic instrument" property.</div><div><br></div><div>Also non-uniformity of bend range between keys can sound interesting </div><div><br></div><div>(or terrible, as I'm discovering with this strange beast I've recently taken delivery of...)</div><div><br></div><div>A</div><div><br></div><div><br></div><div><div style="display: block;"><div style="-webkit-user-select: all; -webkit-user-drag: element; display: inline-block;" class="apple-rich-link" draggable="true" role="link" data-url="https://suzukimusic-global.com/products_single.php?parent_cate_cd=2&products_cate_cd=20&products_cd=178"><a style="border-radius:10px;font-family:-apple-system, Helvetica, Arial, sans-serif;display:block;-webkit-user-select:none;width:300px;user-select:none;-webkit-user-modify:read-only;user-modify:read-only;overflow:hidden;text-decoration:none;" class="lp-rich-link" rel="nofollow" href="https://suzukimusic-global.com/products_single.php?parent_cate_cd=2&products_cate_cd=20&products_cd=178" dir="ltr" role="button" draggable="false" width="300"><table style="table-layout:fixed;border-collapse:collapse;width:300px;background-color:#E5E6E9;font-family:-apple-system, Helvetica, Arial, sans-serif;" class="lp-rich-link-emailBaseTable" cellpadding="0" cellspacing="0" border="0" width="300"><tbody><tr><td vertical-align="center"><table bgcolor="#E5E6E9" cellpadding="0" cellspacing="0" width="300" style="font-family:-apple-system, Helvetica, Arial, sans-serif;table-layout:fixed;background-color:rgba(229, 230, 233, 1);" class="lp-rich-link-captionBar"><tbody><tr><td style="padding:8px 0px 8px 0px;" class="lp-rich-link-captionBar-textStackItem"><div style="max-width:100%;margin:0px 16px 0px 16px;overflow:hidden;" class="lp-rich-link-captionBar-textStack"><div style="word-wrap:break-word;font-weight:500;font-size:12px;overflow:hidden;text-overflow:ellipsis;text-align:left;" class="lp-rich-link-captionBar-textStack-topCaption-leading"><a rel="nofollow" href="https://suzukimusic-global.com/products_single.php?parent_cate_cd=2&products_cate_cd=20&products_cd=178" style="text-decoration: none" draggable="false"><font color="#272727" style="color: rgba(0, 0, 0, 0.847059);">Suzuki products | Suzuki Musical Inst.
