Hi,

It is not obvious at first and takes a bit of learning, but you can create the sections in MMM as you did with your Yamaha. I still don't quite understand how to make it work 100% but I am getting there, so this is also for me to remember how I did it. If anyone has anything to add or correct, please do so. This was the first time I tried this. I am using MMM2014 Premium, a Casio keyboard connected to USB input and a ASIO4All driver.

Preliminary steps:

1. Turn on keyboard and set it to Midi, Local off;
2. Open MMM;
3. Program settings load ASIO driver;
4. Make sure that sound comes out speakers or earphones by testing a soundpool;
5. Set up the BPM;
6. Turn on the metronome.

Midi recording:

1. Add instrument, say drums to track 1 and click on the track record button to arm MIDI REC (probably have to click twice);
2. Right click on the yellow bar line at 4 bars;
3. Right click on the empty track 1 and select create new midi object, give it a 4 bar length. It will be created on the track;
4. Double-click on this empty midi object to open the Midi Editor;
5. Depending on what you want to do, and since I want drums first, click on Overdub and Cycle at the bottom of the screen. Metronome should already be on;
6. Press REC. I let it go through the 4 bars and then start with bass drum and do the 4 bars;
7. Keep recording, the bass drum will be heard when the first bar comes around;
8. Do something else, like a snare drum, go through the 4 bars;
9. Then add cymbals through the 4 bars, etc. keep going until all percussions are there;
10. Stop recording. It doesn't matter when as the midi just keeps looping through the 4 bars;
11. Verify recording in Midi Editor;
12. Close the Midi Editor (may be a good time to save the project);
13. Add instrument to track 2, say bass, and click on the track record button to arm MIDI REC;
14. Right-click in empty area of track 2 and select create new midi object, give it a 4 bar length. It will be created on the track;
15. Double-click on this empty midi object to open the Midi Editor;
16. The same set up should be there, 4 bars at the top, Overdub, Cycle and Metronome at the bottom;
17. Press REC, go through 4 bars and start playing for 4 bars;
18. Stop recording;
19. Repeat steps 11 to to 18 by adding another instrument to track 3;
20. Close the Midi Editor;
21. Ready for next part;
22. Right click on yellow bar line the end of the next section, say at the end of bar 12 and drag the left end of the yellow bar to the beginning of bar 5;
23. Arm track 1 for drums;
24. Go to step to 3, but select 8 bars this time if that is what you want to record;
25. Continue with step 4 as before;
26. Repeat from step 22 for more parts of the song. Instead of an instrument already there, you can add one to track 4, then 5, etc., and record where you want, just move the yellow bar marker to get the looping.

Notes:

1. There are sometimes problems with recording and everything or almost everything comes at the beginning of the recording. If so, stop, select anywhere on the Midi editor screen, Ctrl+A to select all, then Delete. Start the recording again.
2. Note that the notes do not come up in the midi editor right away, but that they will be played during the next loop.
3. You can keep the Recording loop going and jump in if you missed a bar.
4. Sometimes the Arranger will show 5 bars instead of 4 or 9 bars instead of 8 after recording and closing the Midi Editor. Simply drag the right end to the left by one bar. Nothing should have been recorded there anyway, but sometimes it is and you have to go back and fix it in the Midi Editor.
5. I did not cover Grid quantization and Length quantization value. You should look these up and set them correctly before recording.
6. Save the project often and occasionally do a Save As and change or append something at the end of the file name like adding r1 for revision 1, then 2, 3 etc. in case something bad happens, like a crash. You don't want to lose all of your work.

Below is a screen shot of my test. Note that I went back and added an instrument on track 6 and recorded it after doing the other parts.

Below is the Midi Editor screen showing the instrument on track 6.

Good luck!
