11.10 Pro Tools MIDI Compatibility (Pt)

Default: Off
Available settings: On, Off
The Micstasy is MIDI remote compatible to Digidesign's Pro Tools system. The extended func-
tionality of the Micstasy (e.g. much smaller gain steps) is not available here, because the
Digidesign protocol does not support those features.
The Pro Tools micpre MIDI protocol uses simple controller messages and is therefore unpro-
tected. Other MIDI devices like keyboards etc. shall not be active on the same MIDI line, other-
wise certain values within the Micstasy will most probably be changed randomly. Because of
this, the Pro Tools compatibility is switched off by default.

11.11 Digital Output (do)

Default: An
Available settings: An, oP
This option relates to the use of the I64 MADI Card. In default state (An) the analog input signal
is available at all three digital outputs. Selecting oP (Option) an eight-channel group of the
MADI input signal is sent to the ADAT/AES outputs. With this the MADI connection can also be
used as return path. Sending audio via MADI to the Micstasy, the audio becomes available at
the Micstasy's digital outputs ADAT/AES. The MADI output continues to carry the analog input
signals and the fed-through input data.
Note: The 8-channel group sent to ADAT/AES is defined by the currently chosen ID.

11.12 Word Clock Out (Co)

Default: FS
Available settings: Si, FS
Si stands for Always Single Speed, FS for the current sample rate or Follow Sample rate. In
default state (FS) the word clock output follows the current sample rate up to 192 kHz. Selecting
Si causes the word clock output to always stay within the range of 32 kHz to 48 kHz. So at 96
kHz and 192 kHz sample rate, the output word clock is 48 kHz.
Note: A reliable sample-accurate synchronicity between multiple devices having digital inter-
faces in S/MUX technology (ADAT and MADI*) at sample rates in the Double Speed and Quad
Speed range is only possible when all units are synced by Single Speed word clock. Because of
the S/MUX method the device else can not know which of the incoming 2 (DS) or 4 (QS) word
clock edges is the right one.
* With the Micstasy this limitation is also valid for the AES output, as the device internally handles all the data streams in
S/MUX mode.
