The stereo version of an eects block will use roughly twice as much DSP as
a mono version of the same block. Therefore, there is no sense to adding a
stereo block before an IR or other mono type block (since the signal will be
summed to mono anyway - see "Block Order and Stereo Imaging").
Some model categories have “Simple” blocks, which utilize less DSP than
others.
Instead of toggling between two of the same eects blocks (with dierent
settings), use controllers or snapshots to instantly adjust parameters within a
single block.
Block Order and Stereo Imaging
The HX Eects device signal path is stereo, carrying two channels of audio. When the
device is fed a stereo input source (i.e. - when discrete left & right signals are con-
nected into the device's Left and Right input jacks), the source audio is processed
discretely in stereo, wherever stereo blocks are used within the path. Whenever a
mono block is added within a path, both channels of audio are combined and sent out
of the block as mono.
Most eects models have both Mono and Stereo versions. The stereo imaging is
highly dependent on the type of blocks you add, and in what order.
Legacy eects models vary in behavior, just as on the classic Line 6 eects from
where these models originated.
Legacy Distortion, Dynamics & Pitch/Synth eects are mono.
Legacy Modulation & Delay eects vary in that some are mono, some stereo,
and some mono-in/stereo-out, where adjusting the eect's Mix parameter
can narrow the stereo image that is fed into them. It is best to experiment
with these eects and tweak the Mix parameter to achieve the desired stereo
output results.
Legacy Filter and Reverb eects are stereo.
