Look at the demo songs that came with MMM to see how Magix did it. See the start up screen and select Demo songs.
There are 7 chords in the soundpools, usually. That's it. Outside of that, you can use Pitchshift to get a bit more, but basically you would have to make your own, especially if you want other majors and minors.
Click on the Pitch number beside the soundpool. The key shows up on the table to the right. See below.
What you see in the Arranger is one of the Demo songs.You can learn a lot by observing how it was put together.
After Struggling for a whole day and ignoring family affection. God Bless music and my Family. I managed to work around the pitch shift chord thingy problem>>>>>
Okay, whatever version of magix music studio you are using, they have provided you with numbers that represent chords either major or a minor. ( you can find the numbers on top of your soundpool.
1 is a C major chrod.
2 is a D minor chord.
3 is a E minor chord.
4 is a F major chord.
5 is a G major chord.
6 is a A minor chord.
7 is a A sharp major chord.
Now let us say your song starts with C minor, go to the soundpool click on the sound you like, (do not drag it to the empty track yet) then select on the number that is closes to C minor let us say number 2 since it is D minor, drag and put it in your track. double click on it to open or use ctrl and O.
once object editor is open use the pitch shift wheel to adjust the chord until it sounds like a C minor. or you can count in half steps going backwards(I think). remember if you want a to change to a major chord repeat the same process and select a major sound this time.
You did very well - learn by doing.....and reading the manual. Try everything you can to help learn. Look at all of the menus and submenus, including those by right-clicking an object. I usually use F1 and look up whatever I think I want or I have the pdf manual open and do the same. There is a lot to learn about this program. You are just getting started.
One thing about the keys, 1 is not always C major. I was sure that I saw some that were different and I found one, Electro Lounge, in which 1 = C minor, 2 = D minor, etc.... and there is no 7.
Best of Techno Vol. 1, 1 = C minor
Everything else that I have is C major.
Note on the bottom of hte Soundpool screen that there are filters. You have audio loops and midi loops. Of course the midi loops can be easily transposed.
I know about the family part, my wife reminds me often to get off of the computer.
