BPM Calculator revisited.

[Musart]

Hi to all.

I've almost finished my project. The challenge was :

I had to compose musical parts (midi and waves) for a vocal track (a capella). The difficulty was to sync the musical midi parts with the vocal part which i don't know the BPM.

I did it by composing and adjusting all the midi notes in the piano roll view to fit what i hear in the vocal track. It was long but effective. Great results. The inconvienent is all the notes are not aligned within beat and measures and BPM.

In one words, i fit the midi with the vocal.

But i will have more project like this ...

My question is :

I want to do the inverse of what i did. I want to fit the vocal track (a capella) to a constant BPM midi parts by stretching the vocal track. Is there any techniques or tutorial to do this easily ?

Remixes songs like (Elvis - A little les conversation and Janis Joplin - Mercedez Band) are good example of what i mean.

Thanks to all.

I can give some advice on the first part of your post. If you get Akoff composer you do not need to enter the vocals into midi notes. Akoff converts wavs to midi for you. The second part of your problem is of great interest to me.I.e. how to fit the midi to the vocals bpm. I tried every way in the book, the internet and everywhere else. The hard way is the only way that works.

Listen to the track over headphones and use a pen to click the beats while recording the clicks in an audio track. Then, go to audio, exttract timing and extract the timing from the audio track and select insert tempo changes. Preview your results first and play with the various setting.

Other ppl recommend to use a midi keayboard to record the clicks,and then use the midi fit to improvasation, but I never had good results with that method.

Thank for answering.

On the first part, i did not enter the vocal into midi notes. What i meant is i composed the bass and drum parts into midi and i had to enter them manually to get them in sync (aligned) with the vocal part. I am not a keyboard player so i have to do it manually.

For basic timing, i record my guitar for simulating a click and did an extract timing so i had a midi beat (that's great). Then i compose midi drum and bass based on the midi beat.

I am sure that exist a technic to work with streching wave to sync the midi beat. If I find something i'll let you know for sure !

Thank you
