38.3 Limitations and Important Notes
The media must be formatted as FAT32, primary type. Logical partitions are not supported. With
volumes having more than one partition, a different partition than default partition 1 can be se-
lected in Rec/Play Settings, USB Media.
A recording is always stopped when the sample rate changes.
Changing the record configuration (armed channels) is not possible during an ongoing record-
ing. Channels are recorded without placeholders and without labelling, in straight ascending
order. For a playback on the exact same channels, the playback channels have to be selected
accordingly in TM FX or the unit.
The recording is done at the current sample rate as 24 bit WAV file. A file can be up to 2 GB in
size and includes all (up to 40) channels in interleaved format. The filename is UFX01_00.wav.
After reaching the 2 GB limit a new file is automatically written, with an incremental file number
(UFX01_01.wav). The UFX will write up to 100 files consecutively (UFX_01_99.wav). After that,
a new recording has to be started (UFX02_00.wav).
At a sample rate of 48 kHz, up to 40 channels (all inputs and outputs), at 96 kHz 32 channels, at
192 kHz 16 channels can be selected. Therefore at 48 kHz and 96 kHz all available inputs and
outputs can be recorded simultaneously. The actual number of channels that can be used error-
free depends on the media, see chapter 38.5.
The playback from a storage device does not change the current sample rate. To match pitch
and speed, the sample rate has to be set manually to the correct value. Playback can be as-
signed to multiple outputs.
The UFX can play back externally recorded WAV files, as long as these have 16 or 24 bit resolu-
tion.
The recording signal is taken before EQ and Dynamics, on both inputs and outputs. To record
with EQ/Dyn, activate REC on an output and route a signal processed by the input EQ/Dyn to
that output. The insert point of playback is at the same place.
