Tiptop Bus Mix.
The Bus Mix is a technology we have developed to mix signals coming from
modules without the use of patch cables to physically connect them to the mixer.
This is done by sending the signal through the bus board and picking them up
by the MIXZ. At this moment this manual is being written the modules that have
Bus Mix are all of the Tiptop drum modules. You can decide which modules
you want to connect to the Bus Mix and which not, at the back of each of the
drum modules there is a 2 or 3 pin header, enabling this header by placing the
jumper to cover both pins will connect this output to the bus. The Bus Mix lets
you turn on and off a mix of drum sounds with a flip of a switch.

To enable your drum
modules for Bus Mix
look for the header
located on the back of
each module and place
the header on both pins.
You can enable some and
disable others to decide
which ones you want to be
mixed by the MIXZ.
Remember, you can always
add them later to the mix
through the front panel
Mixer A and B.
Example patch
Here is an example patch showing how versatile the MIXZ is. In this example the
MIXZ mixes two Z3000 on Mixer A, going into the Z2040 to make a thick bass
line. The output of the Z2040 then goes to Mixer B, Mixer B also takes in the
HATS909, SD808 and CP909 from the Bus Mix, the mix of all those voices then
goes into the Z-DSP for spatial processing using some stereo delay. In this patch
the BD909 was not enabled so it won’t mix with the other drums, (a good idea if
you run the mix through a delay). And there are still many channels left open on
the MIXZ to add addtional voices into the mix.

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