Dan zou ik zeggen dat je tussenstappen gewoon het probleem zijn. de route van synth-out -> speaker is korter als de route van synth-out -> audio file recording met zijn preferences/conversie -> speakers.
Gebruik je in je synths audiofile misschien de niet gewenste panninglaw of op je kaart een extra optie?
------------
Panning laws originated in the days of analog mixers. If there was a linear gain increase in one channel and a linear gain decrease in the other channel to change the stereo position, at the center position the sum of the two channels sounded louder than if the signal was panned full left or full right.
To compensate for this, it became common to use a logarithmic gain change response to drop the signal by ‑3dB RMS at the center. You could do this by using dual pots for panning with log/antilog tapers, but as those could be hard to find, you could do pretty much the same thing by adding tapering resistors to standard linear potentiometers. Thus, even though signals were being added together from the left and right channels, the apparent level was the same when centered because they had equal power.
But this "law" was not a standard. Some engineers preferred to drop the center level a bit more, either because they liked the signal to seem louder as it moved out of the main center zone, or because signals that "clumped up" around the center tended to "monoize" the signal. So, dropping their levels a little further created more of an illusion of stereo. And some of the people using analog consoles had their own little secret tweaks to change the panning characteristics.
