Tempo Map/Grid "Warp"
Simple idea really, the ability to click and drag markers/gridlines to essentially "warp" the grid. See http://forum.cockos.com/showpost.php?p=36768&postcount=22

Simple idea really, requesting over 3 years ago, the ability to click and drag markers/gridlines to essentially "warp" the grid.

Something like this:

See: http://forum.cockos.com/showpost.php?p=36768

It should be possible to do on any tempo marker, no matter if it's on the measure, beat, or anywhere in-between. It would just adjust the previous tempo value so that the following tempo changes stay at the same time value. Of course, movement would be restricted to normal tempo ranges (like 40-280 BPM)

I promise I'm not grumpy that this feature has not yet been implemented :) but I just wanted to show a demo of exactly kind of behavior I was initially envisioning:

Something along these lines would be incredibly helpful when trying to map a project to a "live" solo performance (e.g., an acoustic guitarist/singer recorded without a click).

So far as I can tell, the best ways to tempo-map a project in REAPER currently involve create tons of markers and then slicing the track item into measures (examples):


These methods are fairly easy and doable when you are working with 4/4 material that has consistent and audible measure-divisions. The problem is threefold:

1. It is extremely difficult to "adjust" the resulting tempo map if you guessed your measure-divisions incorrectly (e.g. a "free-time" solo or mixed-tempo/mixed time-signature project where the best measure divisions are not always obvious until you start adding other tracks)

2. It severely restricts overall functionality with regards to project markers, take-management, item-divisions, etc. I.e., the kinds of material where this would be most useful are also often the kinds of things where markers, take-splits, etc are also common.

3. It makes for really ugly and difficult-to-manage projects when you have to set markers and split takes at every measure division/tempo change.

I suspect that there is already an easier and more elegant way to do this with REAPER's current capabilities, but I haven't been able to figure it out.

3. It's a really ugly and inelegant
