Photon X25
Requirements/Setting up:
To use the Photon X25 with Reason version 4, you should select a “default” pre-
set (or the “Reason version 4,” preset, if that is included in the device).
If you have overwritten all default presets in the Photon X25, you can create a
Reason version 4 preset by making the following assignments for the Photon
controls:
About the controls:
The Photon X25 has ten knobs with three “layers”. This means that there are re-
ally 30 different knobs available for use in Reason version 4,. If you use Remote
Override mappings, the knobs are named “Knob 1-1”, “Knob 1-2” and so on up to
“Knob 3-10” (the first number denotes the layer and the second is the knob num-
ber).
For the AXYZ dome to be active, you need to press the button next to it.
About the default mapping:
D When controlling devices with few parameters, not all knob layers
will be used.
If nothing happens when you turn a knob, make sure layer 1 is selected on the
Photon X25!
D By default, the AXYZ dome is mapped to Breath (X axis), Channel
Pressure (Y axis) and Mod Wheel (Z axis).
Whether Breath and/or Channel Pressure is received depends on the set-
tings in the Reason version 4, devices. Remember that you can use Remote
Overrides to map the AXYZ dome to whatever parameter you like.
D For devices with patches, buttons 7 and 8 select the previous and
next patch, respectively.
D Buttons 9 and 10 are used for Target Previous/Next Track (move the
master keyboard input up or down in the track list).
D Pattern devices uses the following buttons:
When you select another bank, you need to select a pattern before the bank
select takes effect.
D Mixer 14:2
There are two keyboard shortcut variations: “Levels and Pan” and “Sends”.
When the “Levels and Pan” variation is selected, the upper row of knobs con-
trol pans, and the lower row controls levels, with knob 3-10 being the master
level.
When the “Sends” variation is selected, the upper and lower rows control Aux
sends 1 and 2, respectively. The Aux return levels are on knobs 3-5 and 3-10.
In both variations, you select which mixer channels to control by using the
Layers (channel 1-5, 6-10 or 11-14).

Buttons 1 and 2 control the Thor front panel buttons 1 & 2. The knobs in layer
1 control Rotaries 1 and 2 and filter parameters. Layer 2 control Osc and Amp
Env and layer 3 control LFO, Amp, Delay, Shaper and Portamento parameters.
