Tempo stretching

[tristancalvaire]

Within Logic, what are some ways I could transition from one tempo to another, without a jump?

 

For example, let's say I wanted to go from 160 BPM all the way down to 80 over ~ 16 bars of time.

Is it possible to:

1. Automate this?

2. Apply it to the entire song, including MIDI and Audio?

3. Do it linearly?

4. Do it with an acceleration?

 

If there isn't a feature like this, what are some theory ways I could make a smooth transition with the tempo slowly decreasing from 160 to 80, without a simple jump from full tempo to half-tempo?

 

Thanks!

here's how i'd do it,

but as you can see there are other options

let us know how you get on

 

p.s, this applies to midi and project tempo, but audio is a different thing entirely

Thank you el-bo! That's exactly what I needed... I really should read manuals more carefully >.>

 

As for audio, that shouldn't be too much of a problem. I mostly use virtual instruments nowadays, and as for vocals I can just splice them up into EXS24 and play them rhythmically, stutters/glitches etc.

IME, this kind of tempo change works really well with MIDI but has some downsides with audio.

 

Voices in particular will sound odd and glitchy if a tempo change is gradual over a held note. OTOH, if you can manage to insert tempo changes at pauses in the vocal or right on a consonant, then the change will be a lot smoother. But any audio that has a held note will sound strange with a gradual tempo change over it. That's just what I've encountered so YMMV!

sometimes people just need a nudge in the right direction

 

have a look into flex time for audio slicing and manipulation, for an alternative flavour

I'd also like to do really big audio stretches to get a nice, glitchy texture I can turn into an instrument of its own.

 

Would time manipulation akin to this be possible with Flex or another Logic feature?
