siderealxxx Posted November 27, 2013 Share Posted November 27, 2013 Hi - I have another MIDI transform question… I've never been able to get this function to perform correctly (sometimes only by luck). I have a MIDI region in which I wish to perform a relative diminuendo, so that the first note is 127 and the last is 0, but that everything in between diminuendos relatively. You can see the region here: I have the transform set close to what I think it should be, but no matter what settings I try everything just goes flat to 127, or something random happens or nothing at all. I'd like to learn this once and for all because I've been trying to do it for years!!!! Help appreciated Link to comment Share on other sites More sharing options...
siderealxxx Posted November 27, 2013 Author Share Posted November 27, 2013 That velocity perameter goes up to 8191… WHAT ON EARTH DOES THAT RELATE TO?!?!?!?!?!?!?! Link to comment Share on other sites More sharing options...
Eriksimon Posted November 27, 2013 Share Posted November 27, 2013 Keep in mind that the position parameter is relative to the region start! Also: why not just use "crescendo"? At least it has the normal range (0-127) for velocity... Link to comment Share on other sites More sharing options...
siderealxxx Posted November 27, 2013 Author Share Posted November 27, 2013 EricS, yes I realised the position relates to the region start, not the project start but that still didn't help anyway. And the reason I can't use straight crescendo is because as you can see there are notes which are at a higher velocity and I need to preserve the relative levels as it diminuendos. Can someone confirm if this feature actually works because I've never had much luck with it and I need it quite a lot.... It's either too complicated or buggy (or I'm being a doofus) - please enlighten!!! ?????? Link to comment Share on other sites More sharing options...
Eriksimon Posted November 27, 2013 Share Posted November 27, 2013 Yeah, I've played briefly with it and I also find it strange that it works with a 14 bits value, but it does appear to yield results... if I were you I'd experiment with a copy of that region, just to observe the behaviour using different ranges. So lots of operate-see-undo... The manual is really uninsightful and unspecific and uselessly shallow: • Rel.Cres: This only works if the Inside Position selection condition is selected. The effect is similar to that achieved by Crescendo*), but the previous values of the parameters being altered are taken into account when the crescendo is created, preserving the relative feel of the original. *) • Crescendo creates a smooth alteration of the current parameters, between the set value boundaries. http://help.apple.com/logicpro/mac/10/#lgcp21584fd3 Link to comment Share on other sites More sharing options...
siderealxxx Posted November 27, 2013 Author Share Posted November 27, 2013 Yeh, I've tried all sorts of variations and still can't get it to behave correctly... disappointing. I'm sure I've had it work in the past on occasion but it's always been random but now I'm getting nothing. Link to comment Share on other sites More sharing options...
Jordi Torres Posted November 27, 2013 Share Posted November 27, 2013 Seems to be working fine here: J. Link to comment Share on other sites More sharing options...
siderealxxx Posted November 27, 2013 Author Share Posted November 27, 2013 Ah... You left the top figure at 0 and the bottom figure as a minus figure... I was working with positive values! I'll check this tomorrow but you might've just cracked it. Thanks! Link to comment Share on other sites More sharing options...

Jordi Torres Posted November 27, 2013 Share Posted November 27, 2013 The way this works reminds me of Pitch Bend wheel where you have zero in the middle then 8191 up or down from there (Erik already mentioned the 14bit deal and you yourself noticed it went up to 8191). So the way it works for diminuendos is like this: Higher positive values in the upper field will give you a diminuendo that starts off louder, and lower negative values in the lower field will give you a diminuendo that ends quieter.
