uneven audio attributes among instruments for exactly same notes

[anytizer]

When you "export tracks" and check the time lengths for same notes, bpm and output format settings, you will find that the artifacts are with different play time lengths and other attributes.

Open the attached sample, export the tracks, and load all .ogg files in Audacity.
Then see the ending times. In my opinion, they should contain equal amount of playtimes.

How to reproduce? Please consider the project: exports.zip

Copy some notes, eg 2 bars long to some default instruments.

• Then apply same channel number to ensure they have common effects, if any.
• Export all tracks using the File > Export Tracks menu.
• Open all artifacts together in a stack using Audacity or MP3Tag

They have different play times! causing overlapping sounds.

Each instrument seems to have a different bitrate output

Wait.. are these

The same notes in exported tracks played by those instruments?
Have i marked them correctly??!
Thats.. insane..
Surely those cant be the same notes being played by those different instruments 😱
Only 3. and 4. are even similar -and those should be resp. lb302 and Bitinvader?!???
Totally different type of instruments
There is something i dont understand in this..

I need to clarify further in your markings, as I could not include all instruments' ending positions. The graph seems to be, starting as 10_Xpressive (left/right channels), 1_TrippleOscillator, 2_... .

They have stereo channels, and each 2 of them are from same instrument.

Confirmed that: Xpressive appears to have different outputs in different channels, and is the first 2 graphs in the picture above.
(May inspire to further check on its output)

This graph mentions the filenames.

Ok so stereo -I should have seen that -sorry
Neither Xpressive nor LB302 can be used for a thing like this, because they are default modulated, and special, and is the real reason for this misunderstanding, because it is a misunderstanding.
The length are the same, but the shape is different , because there are used different generators!
But look at the length in your second graphic, there the length are identical!
If you set set the same generator for these instruments,

3OSC
Nescaline
Freeboy
Default zynAddSubFX

witch are all default unmodulated both the shapes and the length will be the same.
Set all to Sine, because Default zynAddSubFX is Sine

The length are the same, but the shape is different ...

The problem is that the ending lengths are not same. The shapes can be different, though.

Oh.. i thought you showed me the whole shape for all, and that they all ended at this red line i have drawn, and they do not?
Please make screeny where all the shapes reach center0, just like this one:
