I have recently found a problem with my Photon25 and Live where it only recognises keys from my keyboard and not the knob controls. It was working fine until a few days ago. The same problem also occurs with Reason 3, again with only keys being recognised.

Thanks in advance.

The knobs can be set to send on different midi-channels as well as different control change numbers. You might want to check that.

I have tried changing the midi channel, but this just affects the keys. I am using auto detection and still only the keys are registering.
It's as if the controls have been disabled.
Is there anyway of resetting the keyboard?

Take a look at this bit from the manual. Knobs can be assigned to individual Midi channels. That might be your problem.

Assigning Knobs
Use the LAYER button to choose the layer you want to edit. Press EDIT
PRESET then wiggle a knob to select that knob for editing.
? Press the PAGE RIGHT button.
? Turn VALUE/ENTER to change the MIDI continuous control (CC)
number associated to the knob.
? At this point, the knob is assigned and ready to use—You can push the
RECALL PRESET button to return to the main menu and start twiddling
the knob. However, you can access additional MIDI options by pressing the
PAGE RIGHT button. These options include:
- The MIDI channel of the knob. The default setting is Comn which
sends out the CC information on the common channel (see below) but
you can set the knob to send MIDI out on a channel from 1 to 16.
- The Common MIDI channel. All of the knobs set to Comn will be sent
on this channel.
- The name of your preset. Use the PAGE LEFT and PAGE RIGHT
buttons to move the cursor forward and back and the
VALUE/ENTER knob to select letters, numbers, and spaces.
