Yes the key of A major has 3 minor chords Bmin, C#min and F#min plus G#dim along with A maj, Dmaj and E7. However, the scale for solos often isn’t a straight major scale. Sometimes you find A pentatonic or A Dorian or A Mixolodian being used for a solo in a Major key with the “wrong” notes giving it tensing or bluesyness. You just need to figure out what the harmonies are and choose the right scale.
Wheresthedug: Your contribution is really great, but you're losing me at this point, unfortunately. I'm totally not familiar with this stuff. I'm just a listening by ear and autodidact playing guy....without theoretical knowledge in this matter. I only know chords and can't tell anything about scales .
There is a really good thread on how to use user scales, you could see if that (User scale) could work for the minor / major chords in your case:

Too early for me to start making noise but will check if the key scale knob really does not do anything for me either.
ToneDeaf: I owe you also for your reply but I don't understand the matter (BTW it's all in English and that's an extra handicap in reading and understanding this technical stuff for someone like me from The Netherlands...)
So I studied videos of demonstrating a Boss PS-6 Harmonist Pitch Shifter. https://www.youtube.com/watch?v=LzpXFHqujfY In this video it's clear to me that I indeed have to pick a key first and after that set for a minor or major scale.
But how to determine that? I would love to learn this. So we're talking about the song If you can't give me love from Suzie Quattro. This song is in the key of A major (right?) I start with my solo: B15 to17 then B14 to again 15-17 The second harmony
is B12-14 then B10 and again B12 -14
The interval is 3 semitones (right?)
How to set this in Kemper's Harmony stomp?
