What players (except ModPlugPlayer - very inconvenient) support a format mptm?
Can be eat plug-ins for WinAMP or AIMP?
In AIMP the excellent plug-in for mod-music reproduction (it, s3m, mod etc.) But mptm in it is not supported... :(
You can try XMPlay, Winamp, or foobar2000 with OpenMPT plugin:

https://www.foobar2000.org/components/view/foo_openmpt54
Any player based on libopenmpt will play MPTM (except for VST plugins and non-default DMO plugins, for security reasons).
See https://wiki.openmpt.org/Libopenmpt#Software_using_libopenmpt (https://wiki.openmpt.org/Libopenmpt#Software_using_libopenmpt) for a list of player eithers directly shipping with libopenmpt playback, or plugins for other players and media frameworks).
Also note that MPTM is a superset of IT, thus players supporting IT may, to a varying degree, also support MPTM.
