Fl Studio Change Tempo Without Stretching
Addison Mauldin
For some reason, if I try to use an automation clip for the tempo the audio all glitches out randomly and I'm not sure how to fix this. Is there a way to change the tempo of the song and not have to resize the clips? I can't resize the clips to such a high tempo and this has turned out to be a problem.
I am aware of the stretch button in the playlist editor, but is there a way to lock clips to the grid and not move while changing tempo?
I have three different guitar lines all layered and I just want to bump up the tempo just slightly but this results in the stretching or at least moving of the clips and it no longer matches the drums or even other guitar lines.
Very useful feature on scenarios where you have a recorded midi data that doesn't fit into the tempo of the project. And you wanna change the tempo without altering the timing of midi data. There are different situations that lead to this and there are many threads on old forum where people request this feature for various reasons. This is still do able in CbB with complex procedures like stretching the midi clips post tempo change or using other methods like 'Set Measure/Beat At Now' or 'Fit to time'. The problem is not only that these procedures are bit complex they don't easy provide accurate result.
Recently figured out this is way too easy to do in Cubase and S1. In S1 just change the Time base in inspector from Beats to Seconds and change the tempo. Easy-peasy! Its just the same in cubase you have to change the Timebase from Musical to Linear.
What's more surprising is that CbB actually has the same feature for ages! In inspector change the Timebase from Musical to Absolute. Only it doesn't work! The manual states that it will work but it doesn't work. Either this feature was given up half way under development or it ended up not working due to bug.

The main context in which I would like to lock MIDI to absolute time is for deleting tempo changes that were set incorrectly or were inadvertently left in place while recording a new take without a click.
Apparently its a very important feature than some might assume. I read some old threads abt this feature and I could see some folks questioning
'Why would you record something without tempo?'
"Why would you have a diff tempo?" "Why don't you just rerecord everything" "Wow that's an old case scenario". But in truth I have seen this feature used regularly on day to day basis by composers in professional scoring environment.
For eg: I know this composer who just sits down on this Kawai VPC virtual piano controller starts improvising and starts creating melodies and motifs just like that he lays down diff kind of melodies one after another everything gets recorded as midi in his cubase running virtual piano libraries. Later he chops the midi file to separate each individual melodies and starts figuring out their tempo either by taping or simply using the grid likes. Then he changes the midi to Linear timebase and fix the tempo. He then rerecords if req or simply do some edits and finalize the melody. He says he does the same procedure from old times but using real piano and audio files and these days its handy that its possible with midi aswell.
And then here's another composer who like many likes to set the tempo prior to laying down something, but midway through he slows down the piece and there seems to be some accelerando and ritardando and may be some tempo change aswell. By the time he finished laying down the whole thing the tempo and metronome is no way in sync with what he played. I was curious how he is gonna handle that project grid. He said that's nothing he will just figure out the tempo changes by locking the midifile to linear time.
Provided this being the case I don't think this feature is a wanna be additional feature its a crucial must have core feature for midi centered scoring and music production.
If you say so I must spend more time with it and figure out everything SM/BAN can do. I also usually like the mouse free methods. Here is one of my project situation. Do guide me how to achieve the necessary. Its a 3min long cue starts with tempo of 79bpm. A minimalistic Rhodes riff with some melancholic effect. It stops around the end of 18th measure. Then there is a pause for about 10seconds (abt 3 measure in 79bpm) followed by the same riff now in fast tempo providing a cheerful transition(I figured out its around 102bpm) . Goes on for abt 2mins and ends with a rit. The project is set at 79bpm. So basically I need to change the tempo to 102 from somewhere around the 21st measure without changing the midi durations. How will I change the tempo to 102 from 21st measure without changing the tempo of 79bpm from Measure 1-20. The rest of the tempo changes like pause and rit. or rubato can be taken care with SM/BAN. But how to make a tempo change from 79 to 102 on 21st measure using SM/BAN.
Yes, apparently what I requested was doable. I had to set a tempo node of 79bpm at 21st measure then I placed the Now Time at the point where the cue ends (62nd measure in this case) and set SM/BAN to various different values until I figure out where it would give be a tempo change of 102bpm. So after trying different incremental and detrimental values I figured out by setting the 62nd measure to 74th measure I was able to get the bpm of 102.12(Not precise yet but that will need a little more fiddling). So although doable its a lot of work and much more work compared to being able to lock the midi to absolute time.
This I think is actually a fairly simple scenario. Lets say there are multiple tempo changes, lets say this cue again changes to its original tempo from 62nd measure, that now looks a lot more complex. I tried doing that by setting a 79bpm node at 62 and then using the SM/BAN at 62 that now messes up things setting 62 to 74 at 79bpm. I tried setting a node of 79bpm at 62 and set SM/BAN from 63th measure and perhaps that didn't work. If I tried to change from 61st measure it shows error. Might be an easy task for a mathematical genius. One way to achieve this would be to do the steps I did to change everything after 21st measure to 102bpm and then make a new SM/BAN at where the cue again slows down and ofcourse again try different values and figure out. Or set a node exactly where the tempo change would put the region where the cue slows down prior to making the change itself. Its too complex isn't it for a fairly simple process.
I don't usually have a need to achieve a specific tempo. I usually just want to align the timeline to a live performance without altering it, and the tempo is whatever i played. But once the timeline is aligned, the tempos can be altered as needed. I most often just smooth out any excessive/unintended variation, but one could just as easily change the average tempo of the whole piece or sections of it which seems to be your goal.
Dealing with audio is a customary practice in music production and knowing how to manipulate clips is no different. Time stretching allows us to lengthen or shorten an audio clip without affecting its pitch. This is useful when you want to change or automate the tempo of a project without affecting or stretching the audio.
Stretch modes enable you to change or maintain the pitch and timing of a sample as the tempo changes. They control how the audio clip changes as it is affected by the tempo. FL Studio comes with four different types of stretch modes. Depending on the contents of the audio clip, there are different options that you can use.
Choosing the right stretch mode depends on the type of tempo change, as well as the contents of the audio, and whether the tempo change persists or varies throughout the song. In the next section, we will go over this in detail.
Tempo variations are becoming easier to implement in FL Studio with every release. For example, you may want a beat to start at 120 BPM, change to 140 BPM in the next section, and then end slower at 100 BPM. To do this, first, you have to prepare the audio clips used for the tempo change to be assured that they keep the same pitch and timing. If the tempo changes at different points in the song, use this quick fix to prepare your audio clips for the tempo change.
import an instrumental, then add a tempo meter to detect tempo... then change tempo of project... but OOOPS, that stretches the audio file... how can I change the tempo without affecting the audio file? Thanks!
2) Or, you do the same thing and all that happens is that the audio files are displayed at a different length, but they still play back at their "normal" pitch. That is not a problem, that is the natural behaviour. The audio file will retain its length (in time, i.e. minutes and seconds), whereas the number of beats it covers will change, as the beats not have a different length in time after you changed the project tempo
I can guarantee you that nothing is happening to your audio file, it'll sound the same at any tempo. The only thing that changes is the visual representation, because altering the tempo means you are altering the duration of the bars. The actual length of the audio file stays exactly the same. You can see this if you enable the (secondary) time ruler. Look at this 30 second long audio region for instance, it stays 30 seconds long:
This article explores how we can alter the tempo/BPM of an FL Studio session without changing its pitch. You can do this faster than you may imagine. There are two methods to do so, which we will talk about in detail in this article and also discuss how we can change the BPM of individual samples.
To change the BPM/Tempo of an FL Studio session without affecting its pitch and timings, go to Tools > Macros > Switch all clips to > Realtime stretching. That will change the stretch mode of all the audio clips (loops & samples) in FL Studio to the real-time stretch algorithm.
