### How do I change the speed of each individual frame?

- Quote

Post by j0h00 » Mon Jan 25, 2016 2:39 pm

So i was listening to some of the demo-songs that you get when downloading famitracker, to get some ideas. I saw that some of them had certain frames speed up, while others remained the same speed. I have tried to find out how to do this, but despite my searching I have not found anything about this. Can anyone help?

Use the Fxx (Or whatever it's called) effect that change the speed.
Edit 1 : like Dr. Merio said, you can watch help, Wiki, etc to know what effect does do what.

Like Sky Yoshi said, use the Fxx effect to achieve this. If I recall correctly, values between 00 and 1F will change the speed value, while values equal or higher than 20 will change the tempo.
As a side note, the help file included with FT has an effect list which you can use when you need to know what a certain thing does.

The default split point is 32, but pressing Ctrl+Shift+S changes this split point to 21 so that F15 or above changes the tempo while F14 or below changes the speed.
The split point is stored as the last integer of the PARAMS block, and editing the FTM in a hex editor (or using the SPLIT command for the text importer) allows split points other than those values; in particular, setting the split point to exactly zero turns all Fxx effects into tempo effects, and similarly setting it to 0x100 or above will produce speed effects only (note that text importer only allows 255). The split point will affect the editing of the speed and tempo fields.
F00 is always interpreted as F01. The tempo split point is a concept in the tracker only; the NSF exporter compiles tempo and speed effect commands separately.

Nice, I didn't know about this before.
