Converting tempo values to BPM

[tatqoo]

Could you please recalculate tempo settings to BPM values for reference? It could help with setting up external sequencers / apps / drum apps, etc

Do you have access to a formula that I could convert the Tempo value to BPM?
Or do I have to figure it out on my own? :D

Maybe this page would help? https://guitargearfinder.com/guides/convert-ms-milliseconds-bpm-beats-per-minute-vice-versa/ Mono did it once for me for RMT but I forgot the formula. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Tempo is the duration of one TAB line expressed in the unit 1/50 of a second (for the TV-PAL system)

In SFXMM there is also a value, responsible for visualizing a beat. It is located in TAB->OPT->BEAT STEP

Only with these two values, you can calculate the BPM.

(remember, I'm not a musician and I may not use the right nomenclature)

Now. For SFXMM, the smallest possible tempo is 0 (although this is sometimes not clear in the settings) which is 1/50th of a second.

Let's assume we have a tempo of 5. This will be the value that describes how long one TAB line lasts (the shortest interval between notes). This is not yet a BPM.
To get the BPM value, we need to know how many notes are in a bar. This value is determined by the BEAT STEP.

This gives us:

(tempo) 5 * (notes per bar) 4 = 20 * 1/50s = 20/50s = 0.4s - bar duration.

Now. 1/50th of a second (or 0.02s) corresponds to 3000 BPM - an absurd value, but it will be a starting point.
This value is divided by the tempo increased by one, so

3000 BPM / 6 = 500 BPM

The result of 500 BPM is also absurd, because it means that the length of a beat is equal to one (one note per beat), so every one line we have a beat, but... if you divide it by the number of notes in a bar, you get

500 BPM / 4 = 125 BPM

So, for tempo 5 the BPM value will be 125.

Is this the right value? I think so.

Problems resulting from the above calculations.

A big problem can be rounding, which is not recommended when giving a converted value.

For example, let's take my song DROL SONG. Its tempo is set to 6, so:

3000 BPM / 7 = 428.5714285714286 BPM

is already a problem, and we have one more calculation

428.5714285714286 / 4 = 107.1428571428572 BPM

And this value is unacceptable, yet for such a tempo in SFXMM possible and closest to the original tempo from the DROL game.

I need to get serious about implementing a BPM indicator.

I'm not that fluent in English so I used the translator https://deepl.com :)

Fantastic!

Just remember, that people will be using it in NTSC too. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
