Choosing base note for a temperament is a feature that is missing from Pianoteq interface [users later in this thread pointed out this is only true up until version 6]. The standard way is to use keyboard mapping files - that is "Scala KBM files" - and load them to Pianoteq in the "Keymap" field in the "Tuning" section. You have to make twelve files - one for each note. The only difference between them is one line.
Here is a mapping file for tuning from C - which is the default:
! Size of map. The pattern repeats every so many keys:
12
! First MIDI note number to retune:
0
! Last MIDI note number to retune:
127
! Middle note where the first entry of the mapping is mapped to :
! Change this to change the base note! (60 is C in the middle of a standard size keyboard)
60
! Reference note for which frequency is given (69 is A in the middle of a standard size keyboard):
69
! Frequency to tune the above note to (floating point e.g. 440.0):
440.0
! Scale degree to consider as formal octave (determines difference in pitch
! between adjacent mapping patterns):
12
! Mapping.
! The numbers represent scale degrees mapped to keys. The first entry is for
! the given middle note, the next for subsequent higher keys.

And here is a mapping file for tuning from C# - notice that the only difference is the 9th line:
! Size of map. The pattern repeats every so many keys:
12
! First MIDI note number to retune:
0
! Last MIDI note number to retune:
127
! Middle note where the first entry of the mapping is mapped to:
! Change this to change the base note! (61 is C# in the middle of a standard size keyboard)
61
! Reference note for which frequency is given (69 is A in the middle of a standard size keyboard):
69
! Frequency to tune the above note to (floating point e.g. 440.0):
440.0
! Scale degree to consider as formal octave (determines difference in pitch
! between adjacent mapping patterns):
12
! Mapping.
! The numbers represent scale degrees mapped to keys. The first entry is for
! the given middle note, the next for subsequent higher keys.

To get a mapping file for tuning from D, just change line 9 to 62, and for tuning from D# change line 9 to 63, etc. etc. etc.
Unfortunately this locks in your diapason frequency - so if you want to be able to change the base note in both 440 and 442 you have to make 24 files! If you need to change your diapason a lot you might be better off having just one file and edit it on the fly (although you'd need to restart pianoteq in between edits).
