Speed up entire project, easily, in TW12?

[Ally007]

Hi all... In Waveform12, how can I increase the tempo of an entire project, easily, and without changing the pitch? I set all clips to "remap on tempo change", but no remapping happens, when I change the project tempo. The only thing that changes, is the speed of the metronome and the spacing of the bar markers. Thanks for any help.

PS.. Are audio tracks supposed to remap themselves when the tempo is changed? Mine don't. Sometimes midi drum clips do, but not always.

I think that audio clips only adjust to tempo changes if they have Auto-Tempo turned on. For some audio clips, you wouldn't want the tempo to change, eg. individual drum hits.

Sorry, I think this would be a very daunting task with a lot of possibility for chipmunking. Some tracks would need stretching, others need slicing and moving, others Melodyned, and you'd still wind up re-recording a lot. I don't think any level of mixing or mastering would hide some of the efforts--you'd hear it.

The only thing that ever works is a pure MIDI clip, since that's not audio-based. MIDI drum clips might, but if you've imported them with the "disregard tempo changes" dialogue, they won't.

You're going to have to weigh the amount of time it takes to re-do an entire project versus just re-recording your audio.

For audio, you can render every track to stems and then note what bar marks the end of the track, change tempo and then alt/drag every stem to end at the correct bar. Then select your algorithm (elastique or melodyne)
Then re render the stems. Not saying it will sound good or is a good idea, but it is the basic idea behind countless remixes. You could try it (on a copy of the project, not the original)

Thank you for the suggestion. Actually this project has various speed changes within it. Right now I just want to get the various speed changes sounding ideal, and then I might re-record the whole project with the desired speed changes. OR, I might record the whole project at one speed and then reload the rendered file into a new project and tweak the speeds in it. What do you think?

That might be what I was missing! I must look for that setting. Thank you!

Thank you. I actually want to make several speed changes to the project. I think what I may do is record the whole thing at a constant speed and then load the rendered file into a new project and then tweak the parts than need a slight speed change, using elastique pro - and see how that works out. The speed changes I need are speed increases, so much less chance of unwanted artifacts occurring, I guess. But they are only minor speed changes of no more than +5 bpm.

You might not hear a 5bpm bump at all. Consider rendering the whole project as is and bumping the speed up of the render by 5bpm. Radio stations did more than 5bpm all the time in the 1980s to shorten longer songs and you didn't notice it very often.
