Many people asked me: "What software do you use?"
When I started mixing (1995) I needed software that was not expensive. I did not have the money to buy the pro stuff. So Magix Music Maker was there for fl 99,- (€ 50/60,- now).
For me this was the most complete software. It had all in it that I needed. The most important reason: I do not need an external program to do some pitch job or some other special jobs.
I used Music Maker from the very first start. In the first version you could only use wav files, but now you can drag and drop mp3 files in it. Sometimes I tried other programs to make the mixes, but mostly the other programs does not work like I am used to. And they are much expensive too.
MMM is a multi channel program so you can switch your songs or samples from channel to channel and make the perfect pass in the mix.
I often use some popular songs, selfmade loops and samples from songs to make my mix, but in the Music Maker package are also samples and different kinds of loops delivered.
The other stuff I use:
- Mixmeister BPM Analizer: to do the bpm stuff for each track;
- Excel: to sort the data;
- Sometimes Cool Edit: to make the loops. It can be done with MMM too, but I am used to this, so....
- Mixed in key, for some tonal searching;
- A lot of patience and a lovely patient wive who helps me when I need her. 

In 2020, after almost 25 years, I made the switch to Ableton Live 10. This is a more pro software with the same tools and maybe more than Magix Music Maker.
It is expensiver too, but it is worth it.
I started mixing for The Global Dance Charts in 2019, so more pro software is needed. I made some savings and I bought my own version of Ableton 10 ;-)

So, sorry Magix. After a very long time good work, giving demos and great contact with Magix itself, it is time to move on.
