Save as .mptm not .it

[Abrimaal]

I started a new song.
New module, I imported samples, typed a few base notes.
Now I want to save the file as .mptm to use all features of the tracker.
I Select file type from the list - There is only .it format.

I do not want to save the file as .it

Once I saved a file as .it and it became degraded to 4 channels, many options unavailable.

I am afraid if I save the new music as .it, I will not be able to revert it to .mptm format.
I need help. I leave the computer turned on, MPT is open with an unsaved file, waiting for quick advice.

In OpenMPT, editing a module is already limited to the features supported by the currently used module format. You can select the module type when creating a new module, see https://wiki.openmpt.org/Manual:_Menus#File.

In order to save the module in a different format, you need to convert the module to the desired format first, and then save it. See https://wiki.openmpt.org/Manual:_Song_Properties#Track_Type and https://wiki.openmpt.org/Manual:_Saving_and_exporting#Saving_tracks.

Not sure how that would have happened.

Not sure how that would have happened.

I think I saved the file as .xm file (sorry, it was .xm, not .it)

This time the .it file was saved with all 32 channels, although only 2 are used now in that music sketch. 

I would like to know how to convert the older 4 channel .xm file to a full mpt module.
-------
SOME TIME AFTER
I converted the 4 channel .xm file using:
New MPTM > Append file.xm > Save as .mptm
All notes and sound settings have been preserved.
-------
but... the base of the music was a .med file (1 pattern only) - it contains different notes.
when I tried to append the song, the music was completely wrong.
Maybe I should try to change pattern numbers or sample names (?)
--------
Some time after
Additional question: Can I import tracker files for other computers (other than Amiga)?
Especially I am interested in ZX Spectrum Beepola tracker and Vortex Tracker.
The waveforms and sound settings may be lost, I need the patterns and notes only.
--------
Some time after
Certainly I cannot append these tracker files, but I can append a .wav file, that contains whole music.
Anyway it must be fine-tuned.
Is there any option of fine tuning (auto tuning) a .wav file (that can be treated as a long sample)?
--------
By the way:
I can help with introducing import of Beepola tracker files.
The structure is quite simple, 2 to 4 channels, 1 instrument (but a few samples are required, because of different fade out values).

I would like to know how to convert the older 4 channel .xm file to a full mpt module.

It doesn't matter what the source or target format is, the process is always the same as manx explained: You open the Song Properties dialog and change the track type.
Note that conversion between formats is usually lossy and the result will not sound 100% exactly the same.

OpenMPT can import about than 60 module formats, which are all listed on the feature overview page. Formats from computers that are not sample-based are not supported. That includes SID music and ZX Spectrum music. OpenMPT is first and foremost a sample-based tracker, and supporting different sound chips is not on our agenda. You'll have to find external conversion software if you are just interested in pattern data - OpenMPT generally only supports file formats that it can actually play.
