Can you automate the tempo??? (for example i want intro to start slow at 110 and speed up to 120 for song). Or do I just have to find a loophole to do this. I am sure their is another way, its just automating the tempo button would be much easier.

Yes there is a way to automate the tempo, i never did it exactly in reason but if you rewire to cubase or FL you can have limitless possibilities with aanything you want to do.

Yes, if you rewire into host program like cubase, protools, ableton, it should be pretty easy but I wonder if you can just do it straight up in Reason....sounds like a new challenge for today. If I figure it out, I'll place up a pic tutorial it seems to help alot.

yea i dont know how to do that stuff. so ill just speed up the notes with the note length rather than tempo of song.

bump anyone figure it out yet???

I've look and look numerous times, but I could never find a way to do this. This is really something that I'd love to have as well! But ya, as others said it, the only way I am aware of is rewire.

This excert is written by someone else, but as pointed out in reply's to this post, this doesn't compensate for any tempo dependant filters DDL'S and the like. But it's a neat trick.



OK, first of all, there is no way to automate tempo in Reason. It's the worst thing there is in Reason, but we have to live with it. So, we know what we don't have. But what do we have?

We can move and stretch notes without the magnet, that way we can adjust the right duration and position of every note. So theoretically it 'IS' possible to make tempo changes in the score by scaling the note durations.

This is not a nice solution, but it is the only one I could think of, and it actually works. My latest production (almost ready) had 3 tempo changes, and it sounds all great.

One thing to keep in mind, is that once we scale the notes, we have to forget the ruler, and forget the quantization.

I will explain a good trick on how to do a flawless tempo change in a song, making examples.

Say you want to have a first part in 125bpm, and a second part in 160bpm. You would start composing the first part in 125bpm. Later, you program reason's speed to 160bpm and start composing the second part (the first one should sound much more faster, but ignore that). Now this is important: complete your second part before doing the tempo change. You can switch the tempo back to 125 if you need to re-hear the first one.

Once you have both parts ready, here comes the trick. Select ALL Notes in all instruments from the second part, right click over one and click Change Events.

There is an option to scale the notes. Here comes a bit of math. You must calculate the percentage that should be multiplied to the note's position and duration. You do that by dividing in our case 125/160, and then multiplying by 100. That gives 78,13%.

If you now scale the complete second part with a value of 78,13%, and you set Reason's speed value back tot 125bpm, you will have the effect that you wanted. For the ears, the second part will be at 160bpm.

Hope that this helped you.

wow that sounds really helpful and in depth but i'll have to test it tomorrow. Thanks a ton.

for noobs like myself lowering the notes for a drum beat kinda gives a slower cool effect. Pretty noobie but its good for breakbeat songs

yeah, but there's a catch. all your tempo dependent efects (delays, verbs with tempo synced echo, lfo) will be screwed.

:shrug:

i think reason creators are hyping up tempo automation in the new 4.0 version
