Reversing a fade-out

[kenja]

Hi
I don't think this topic has been covered but if anyone can assist I would be grateful.
I use a Yamaha QY700 to edit midi files to my liking. (I am trying to produce from scratch but that is a long road and another story!).
Faced with a fade-out ending I thought that just applying the reverse i.e. a crescendo to the same measures would do it - apparently not. Increasing all the volumes in turn might work but is very long winded.
Am I missing something and should this be an easy thing to accomplish or not?
Any advice would be gratefully received.
many thanks
Ken

Hi Ken,

It is not always easy here to give a definitive answer because the fadeout could have been done in one of four ways.
There could have been a series of MIDI "master volume" messages applied over time in just one track (the least common).
There could have been a series of "channel volume" messages applied over time but they would usually be in every sounding track (common).
There could have been a series of "channel expression" messages applied over time but they would usually be in every sounding track (uncommon).
Lastly there could have been a series of "note velocity" changes applied over time, again in every sounding track (not uncommon).
Once you have identified which of these is being used (usually the 2nd or 4th) by looking at the "List View" then going to the piano roll and either deleting them all (no.2) in the graphics pane or ramping them back up to a "normal" value is usually quite straightforward.

Looks like the subject of another tutorial?

Does that help any?

Thanks for that John.

I think I have tried this before but I can't remember why I gave up on it. Perhaps it was the large number of alterations - up to 150 or so for a midi with up to 12 tracks - each with several key press operations to accomplish the required volume level.

The upside of this is that most of these repeats leading to the fade-out can be deleted as only about 4 or 6 will required to produce a proper ending.
A new downside will then be a bit of required editing, especially on drums, and ending with the proper chord and note length etc.

I'll let you know how (and if) I get on.

Hi Ken,

It is an edit that can be accomplished in a relatively straightforward way in, for example, CakeWalk. Yes, once for each track or channel, but even then, only a few minutes work once you have the procedure under your belt.

I suspect, re-reading your first post, and noting that you are trying to do it in the QY700, that it is considerably more long winded to do in hardware. I imagine you have to edit every note on event if it is a series of velocity changes. Or go through deleting all the channel volume changes.

I can't remember if these things are easy in the free Anvil sequencer.

Hi JohnG

Yes it is mainly volume changes to be reversed. I must admit I have not tried software programs. I do have a few free ones on my computer waiting to be installed and tested but it's just finding time right now.

Kenja,
Software editing is the only way to go. What you want to do would only take a few seconds per track to do in software.
I would never even attempt to do that in hardware. I'd die of old age before I completed it. <smile>
