I created a moving drone sound in a Combi as follows (writing it off by heart, am not close to my Kronos):
Using 3 programs with a smooth sound on mono (not poly in any case), Hold is switched on. let's call them Drone 1 to 3. Why 3 I tell you further down.
These have a very slow LFO on the Amp and Filter, just very subtle. I used the Guitar waveform for the LFO so no negative values are created and the sound completely disappears.
All three have slightly different LFO speeds to keep the whole thing as organic as possible.
These 3 are put in a Combi with different transposition, 0, 2 and 5 semitones (or was it 0, 2 and 7?). Anyway, it is supposed to form a moving Csus2 chord for example when hitting the C. Am not so good in music theory...

Key range is the last octave of your keyboard.
Especially the sound program for the 2 semitone (the "sus") comes and goes more than the 1 and 5.
With the mono and Hold funtion above you can start a chord and automatically stop and start the next one if you change key.
IFX for the drone have a long delay and reverb setting in order to smoothen out the chord change.
The volume of these 3 is controlled by the verctor stick x-axis, 50% in the centre.
Maybe a better explanation is here:

Piano is the Italian or German Dark. Especially with a strong negative setting on Velocity Intensity (probably -80 or so) and a slight negative on Velocity Bias, probably around -20. With this the pianos sound less harsh and the volume stays loud even if you play quieter parts. As you play harder the sound simply gets brighter.
Then an additional normal pad sound layered with the piano. The volume is controlled by the y-axis of the vector stick, again 50% in the centre.
This pad however is also split into three sounds over 3 key zones (the same sound programs). Each zone is transposed so that there are no "extremes", meaning the lowest pad zone is probably tranposed +2 octaves up, the middle one not transposed, and the highest 1 or 2 octaves down.
In this way it just sounds much smoother when playing in the highest and lowest ranges.

Now happy worshipping
