Tempo change and effects

[Theso]

I've looked around and cannot find a clear answer, so...

How can I change the tempo of certain patterns, and how does one use/input the Zxx effects (I think they are called...)?

[Rakib]

In impulse tracker format (it), or modplug module it is effectnote Axx for tempo.

Zxx can be used for many things, but I primarily use it for cut off filters in modplug modules.

If you want to learn more I suggest the manual found here.

Tempo as in BPM is actually changed using the Txx command in IT/MPTM files, Axx is "speed" which is a bit more coarse way of setting the playback speed (and it won't affect playback speed in modern tempo modes)...
