In the backward position, "dogs" attached to the upper surface of the lower manual engage the lower surface of the upper manual's keys. Depending on choice of keyboard and coupler position, the player can select any of the sets of jacks labeled in "figure 4" as A, or B and C, or all three.</span></div><div><font color="#202122" face="-apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Lato, Helvetica, Arial, sans-serif"><span style="font-size:17.882352828979492px"><br></span></font></div><div><font color="#202122" face="-apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Lato, Helvetica, Arial, sans-serif"><span style="font-size:17.882352828979492px"><br></span></font></div><div><font color="#202122" face="-apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Lato, Helvetica, Arial, sans-serif"><span style="font-size:17.882352828979492px">Kylee<br></span></font><br>On Thursday, April 27, 2023, cheater cheater via Synth-diy <<a href="mailto:synth-diy@synth-diy.org">synth-diy@synth-diy.org</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">As in subject, has anyone seen a keyboard where you can grab the keys<br>
