Re: [LAU] half a tone upper than the reality [qsynth/jack]

Most probably. This is what's missed most of the time if the user doesn't understand the process of up/downsampling. During sequencing the audio files are upsampled live if the project is at a higher rate, and depending on hardware the results vary significantly (you can notice the waveform becoming narrower). Moreover, each application has its own settings for sample rate and they should all be reflecting the same numbers.
