Bit Disable switches are to limit the range of the melody. with 4 bits
running, you get a 16 semintone range. 5 bits, a 32 semintone range and 6
bits a 64 semintone range out of the fixed outputs.

>and then the associated mix ins. Are those ins optional?

Those are for the 4th channel that is fed via pots instead of the fixed
networks. You can wire as many or few of the bits to pots as you wish. If
the switches are included, they will effect the bit 5 and 6 outputs to the
pots. On the other hand, you can simply install only 4 pots (or 3 etc) on
the lower bits.

>and if you decide to omit them, should the disable switches be closed or

open? >And and, what effects do they have on the final outputs?

If you omit the mix ins totally (i.e., dont use any pots) simply don't wire
them up. The bit 5 and 6 switches are still needed for the fixed networks.
If you don't use the switches you will need to short out their positions if
you want to permanently reduce the number of bits. Leave them open if you
want the full range.

I hope that's not too confusing!
