Setup Mode
The Setup Editor
The FX Page
Use the FX Page to distribute processing power (DSP units) for the effects of the zone(s) (or
track(s) in Song Mode) assigned to each MIDI channel. (See Channel on page 7‐7 and Track
Channels on page 10‐7 for details on setting the MIDI channel for each zone/track in Setup/Song
mode respectively.) Each Effect Chain is composed of an effect‐box or a series of effect‐boxes.
Each effect‐box uses a certain amount of the PC3LE's effects processing power. The amount of
processing power used by an effect‐box or Chain reflects how complex the effect's algorithm
is—more complex effects require more processing power. Accordingly, each Chain and effect‐
box uses a certain number of "DSP units"—you can have up to 10 DSP units used at a time in the
current setup or song. The number of DSP units required to load effects for the cursor‐
highlighted channel is shown at the top of the page, followed by the number of total DSP units
required to load all effects for the setup or song. If you attempt to use more than 10 DSP units,
the PC3LE will indicate that you have gone over the limit by displaying (Max 10) on the top line
of the page.
Effects are loaded for as many channels as is possible, until all of the DSP units are used up. In
Setup and Song Mode, the MIDI channel of the lowest used zone/track will have priority for
using DSP units. This zone/track will use as many DSP units as it need for its effects, then the
MIDI channel of the next highest used zone/track will use DSP units to load its effects, and this
continues until all of the DSP units are used up.
If you run out of available DSP units, there are a few methods you can use in order to manage
and free up additional DSP units. First, you can simply disable effects allocation for the MIDI
channels of less important zones/tracks. This is done on the FX page (in either Setup or Song
mode,) which provides per‐channel control over effects allocation (see below.)
Use the cursor buttons to select a channel number (only the channel numbers used in the current
setup/song are shown.) The selected channel will have its Y or N highlighted. The channel
number with a box around it is the specified Aux Effect channel in Setup and Song mode (see
Aux FX Channel on page 7‐64 for Setup mode and FX Track on page 10‐20 for Song mode.) Each
channel can be set to Y to allocate effects for the zone(s)/track(s) assigned to that MIDI channel,
or to N to not allocate effects for that channel. Use the Alpha Wheel or ‐ / + buttons to change
between Y and N. Some channels set to Y may be displayed as (Y). This means that there are not
enough effects resources available for that channel, and that channel's effects are not loaded. As
the cursor is moved from left to right, the ID# and name of the Insert and Aux Effects chains for
each selected channel are displayed on the bottom half of the page (the Aux chain is shown only
if the specified Aux Effects channel is selected.)
Alternatively, if you don't want to disable effects for any channels in order to free up DSP units,
you may want to edit some programs to use different effects that use fewer DSP units (see The
EFFECTS (FX) Page on page 6‐13.) You can enter the Program Editor for a zone's program from
within the Setup Editor. To do this, select the Program field on the CH/PROG page of the Setup
Editor and press the Edit button to the left of the display. When finished, exit the Program
Editor to return to the Setup Editor of the current setup. In song mode, you may wish to allocate
only one channel at a time when recording tracks one at a time to an external multi‐track
recorder. By recording each channel separately, each channel will be able to use 10 DSP units for
its effects.
