@saxmonica – i created the following backing track using
the “IReal Pro” ap on my iPad. It’s just 12 lines,
one line for each major scale, and each line is 8 bars long,
There’s only one chord played in each bar of the backing track.

in each line (ie Major Scale) the
(II) minor7th chord is the 1st bar (Dorian)
(V) dominant7th chord is the 2nd bar (Mixolydian)
(I) major7th chord is in the 3rd and 4th bars (Ionian)
bars 5,6,7,8 are a repeat of bars 1,2,3,4.

The 12 scales follow the circle of 4ths,
so it’s fairly easy to recall the sequence of chords.

I use it for practicing improvisation to the 12 major scales,
and you can improvise using
notes in the Dorian scale (1st bar)
notes in the Mixolydian scale (2nd bar)
notes in the Ionian scale (3 and 4 th bars).

for ex i’ve spent the last 3 months playing the notes
1 2 1 2 for each bar..
in line 1 – 1st bar play the 4 notes B C# B C#
in line 1 – 2nd bar play the 4 notes E F# E F#
in line 1 – 3rd and 4th bar play the 4 notes A B A B
in line 1 – 5th bar play the 4 notes B C# B C#
in line 1 – 6th bar play the 4 notes E F# E F#
in line 1 – 7th and 8th bar play the 4 notes A B A B

Where
B is middle B,
C# is middle C#
E is middle E
F# is middle F#
A is low A

So it’s taught me to remember where the 1st and 2nd notes of all 12 major scales are.

This week i’ve started practicing the 1 2 3 1 for each bar
in line 1 – 1st bar play the 4 notes B C# D B (its a minor chord, dont play D#)
in line 1 – 2nd bar play the 4 notes E F# G# E
in line 1 – 3rd and 4th bar play the 4 notes A B C# A

So this is learning me to remember where the 3rd and 3rd(flat) is for all 12 major
scales..

You get the drift , later i’ll practice 1 2 5 1, lots of different combinations
