<p>I hear you. Its a good idea, I'm just reacting to it doubling the
cost of the board. The clock gennie chips are $2 each and I need
2, so $4. The cheapest DDS is $7. I am hoping the clock gennie
design works because it allows me to do fun stuff like multiply
the outputs to compensate for downstream dividers, and create
other ratios like Hammond or just intonation. I'm still playing
with stuff so we'll see. I don't know if the clock gennie chips
will tolerate bending at all. I guess we'll see.</p>

<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>

<p>I have now ;-) Problem is they are expensive.
Cheapest one I can find that can put out >= 10 MHz
is $7<br>
