I/O Buses Explained; Input Strip Types; Internal Return Buses - Merging Pyramix User Manual

Checking the Connect automatically as many inputs and outputs as possible check-box will cre-
ate the same number and types of Tracks as there are Input Strips and connect as many as possible
to the available physical inputs in ascending order and output Buses to the physical I/O attached to
the Mykerinos board(s) and Track outputs to Mixer Input Strips, although you can easily reconfigure
this later. If the box is not ticked, the tracks will be created in the same way with Track outputs con-
nected to Mixer strips but no physical Inputs or Outputs will be connected.
Clicking Cancel opens the new Project with a Blank Mixer Window (See below)

I/O Buses Explained

The total number of available output buses, regardless of the number of Mykerinos cards, is 64 in HDTDM Mode
and 128 in XDTDM Mode. The maximum number of logical inputs and outputs to Pyramix is also 64 and 128
respectively. However, it is perfectly possible, and permissible, to have more than 128 physical inputs and outputs
connected to a Pyramix system. Routing to assign physical inputs and outputs to Pyramix logical inputs and out-
puts is made in the Settings > Hardware > HDTDM Routing or XDTDM pages. For example: a system containing
three Mykerinos boards, with MADI daughterboards has a total of 192. In HDTDM mode any 128 of these may be
routed to Pyramix logical inputs and any 128 Pyramix logical outputs (less the number of assigned Internal
Return Buses; see below), can be routed to physical outputs.
Note: In a MassCore system these limits are massively increased. In fact the only limita-
tion is the available power. For now the maximum number of buses is artificially limited
in code to 512 (at 1FS, 256@2FS, 128@4FS, 64@8FS).

Input Strip Types

To make is easier to work with a variety of source Formats Pyramix offers a number of different types of Input
Strip. These can control from one to 8 channels from a single set of controls. Please see: Input Strips on
page 160

Internal Return Buses

Some of the time slots on the HDTDM/XDTDM bus or within MassCore can be reserved to convey Aux Send or
Master Output Buses back to input strips. In effect, these are internal send/return paths. To change the number of
available Internal Return Buses, close all open Projects (if any) and go to:
Settings > All Settings > HDTDM Routing or HSR-HTDM if using HTDM mode.
