How many miliseconds is one bar?

Having trouble with LMMS? Ask about it here.
This is a very specific question but I was wondering. Does anyone know how long a bar is (at the standard 140 BPM?)

If it's one second, I suppose that would mean it's 1,000 miliseconds and 1/16 of a bar would be 62.5 miliseconds.

Just wondering because you can't manually set notes in arpeggio in LMMS, so I thought I'd try playing around with emulating this effect in Piano Roll.

Sorry for my OCD lol. :-)
It varies, but you should be able to check alignment within piano roll itself, or with Song Editor.
At 140 bpm, a bar is 1.714 seconds.

It is really not the best way to go, in respect to note-positions in arpeggios.
The reason is that LMMS does not have 'free' placement of notes.
The highest granularity is 1/192 of a bar, so placement calculations depends on multiplum of 1/192. It means that 1/192 is LMMS' minimum-spacing!
So 2 * minimum-spacing would be 1/96, witch also is the 2. finest granular snap or Quantification.
You could at least in theory suppress the snap of 1/192 with holding ALT, but no such luck, the note would still not be placed at a finer granulation. LMMS-file-structure simply dont support it!
So msekd is irrelevant in respect to note positions. You can still use msecd in envelopes and in sample-slices, but not in note-arpeggios.

I see, thank you Musicbear. This was just a little beyond my vocabulary. So essentially LMMS doesn't support extremely short notes for an arpeggio effect? I suppose my best bet is to clone and layer synths playing arp at different notes and sequence the timing (perhaps with just a little delay). I think it'd be neat to modulate the speed too. There are so many interesting things to tinker with!

I have a very long way to go but I'm glad I found this website. It's the best resource there is for learning LMMS!

Thanks again. :-)
You can use short notes for arpeggio effect. In the piano roll, near zoom option, there should be something saying "Q: 1/16," drop-down which allows you to work with varying levels of note placing precision, and the drop-down box next to it that allows you to change note length as and when needed.

OOoooh Nooo That is not so. Just as Monospace says the spacing in LMMS is controlled by the Quantification-choice (Q), but the actual note-length is determined by the choice in the dropdown that default has the option Last-Note
You can use 1/48 std-notes, but if you want even shorter just
* magnify piano-roll
* Grab the edge of any note and make sure you can scale in current Q-value
* Hold ALT
* Drag the note without snap to any size larger that 1/192

1/192 is the general limit of all LMMS size-settings
Nothing in LMMS can be smaller that 1/192 of a bar, but that is also extremely tiny!

If you found this hard to understand let us know, I can make a tutor-video for it

I'm sorry I totally misunderstood you earlier. This was very helpful. I found the big "Q" and it does go down to 1/192. That is extremely tiny! I can definitely get any size note I need this way. I figured out how to zoom in too (Ctrl+scroll wheel). This makes perfect sense and thank you for helping me out there.

I was mostly wondering how you would convert BPM to seconds in one bar (or full note).

I found a calculator that does it but it's too complex. You get too many decimals... (Eg: 140 BPM = 1.7143 seconds in a bar).
https://toolstud.io/music/song-length.p ... _unit=bars

I'm mostly wondering about this so that I can match effects like delay (in miliseconds) with instruments in the song editor. At that point I think I should keep going by ear and do what sounds right. This always works good for me. Trying to be "exact" (within 1/100th of a second) on everything is probably unnecessary.

Thanks again Musicbear and sorry for my OCD. ^_^
You can check in LMMS itself. Calculate the difference of timeline position.

Again, LMMS is one step ahead : D
All dials that logically can use timing, has in their context-menu the option: Synch-to-note.
You do not need to synch anything manually in f.i. Arpeggiator, because you can synch perfectly to all common note-lengths.
Though In AFP there is no option for making a selection of a specific note-length, perhaps we should look at that..
