I would set this priority to low, for such exact fading I would rather recommend using a wave editor.

At some point I wish this feature. I would use a feature like this several times. Is not for a exact fading, I guess that is something like a (f.e.) "slight" fade-in/out instead of modyfing a sample.

I understad like this: http://paste2.org/p/1558747

In 1st & 2nd channel are applied a standard fade in/out, but I guess he means for a starting volume fading like the 4th channel and so for the fade out, start fade in from v48 (f.e.) and stop on fadeout on v16.

I consider this feature useful rather than assign a lower priority.

I would also like to add a secondary request -- linear or logarithmic fading, which would apply a calculation to how the fade approaches it's target value.

BTW, this is mostly for fading interpolated values in the PE, but can be applied to sample data values too.

Mmm... I guess that is in some way similar to http://bugs.openmpt.org/view.php?id=32 get those features also available at both vol & efx column.

Instead of starting a new thread, i'll think i'll just attach a further request to this one in case it gets worked on later.

I went back to work on an old piano suite, and found that the VSTi was being played too loudly, affecting the dynamics of each note. I had volume commands on every note, so i wanted to lessen these values. I found to my chagrin that there's not an Amplify function for all channels in all patterns. Even the Find/Replace dialog does not offer a percentage or value modifier in its functions. Of course i didn't want to reduce the volume per se, so using the volume sliders in the General tab wouldn't have been useful.

We could definitely use a modification to either the Amplify dialog or the Find/Replace dialog. If scripting is far away, perhaps we could incorporate such a feature...

Implemented in r8137 / OpenMPT 1.27.00.46.
