Things important to know about Bus Mix
Enough said, now go make music.

If you have more than one MIXZ module in a row make sure that only one Bus Mix
switch is turned on at a time. You can not mix Bus Mix signals on two or more
MIXZ simultaneously. Also, the MIXZ cannot be placed on any row that uses the
Doepfer CV/GATE bus unless the Bus Mix switch is off.
The maximum amount of channels that can be mixed through the Bus Mix are yet
to be decided, from experiments we performed at the lab we mixed 16 channels of
drum sounds with no problems or limits in headroom. In theory this makes the MIXZ
the largest mixer available in Eurorack today, and only at 10HP and the lowest cost
per channel..
The Bus Mix is not a clean mixing method, it will pick up more noise than standard
mixers like the MIXZ panel Mixers A and B. However, the convenience of the
Bus Mix makes it worth experimenting with. Please note that the Bus Mix is a new
technology that we have tested in systems that use the various Tiptop Eurorack
power supplies with great results. We can not guarantee the same noise
performance using power supplies that are noisy.
Some modules will be noiser than others on the Bus Mix, for example the CP909
has a built-in noise generator: This noise will be picked up by the bus board
and heard if the volume of your sound system is set very high.
In most cases the level of noise on the Bus Mix is not noticeable, we are only
bringing this up in the manual for awareness of it not being low noise.
