<div>But you need only one. Vintage TOG organs used 2 or 4MHz clock and it was enough. Use one clock and constant dividers for each of 12 notes. Pushing it a bit you can achieve smaller tuning errors at higher clock frequency. I made some calculations last year and found pretty good divider ratios that have really small errors and they are not bigger than 1000 AFAIR.<br></div><div><br></div><div>Roman<br></div><div class="nh_extra"><p>Dnia 6 maja 2016 20:21 Tim Ressel <timr@circuitabbey.com> napisaĆ(a):
