Shifting pitch in a MIDI file?

2010-12-13 Thread Angel de Vicente
Hi all, yesterday I was trying to find a way to shift the pitch in a MIDI file but couldn't figure out a way to do it, so I'm looking for advice here... My situation is as follows. I have a MIDI file of a piece (for four guitars), and I just want to mute one of the tracks and play along with

Nice that you found a solution, but it seems to me that you could have some problem with sample rates. maybe you are playing a 44.1ks/s in 48kS/s this could pitch up or the reverse pitchdown. This is often overlook. maybe someone more experienced on this matter can contribute some ideas in here.

You are right, the midi file doesn't carry audio data. but what I was saying is on the sampler/synth side. If the synth is working at 48 Ksamples/s and then played back at 44.1 it will pitch down. If there is no resampling this is the result. Now i don't understand why the output isn't resampled.

I have had similar problems in the past with Qsynth and the remedy was - as indicated by others in this thread - to make sure that the sampling setting in Qsynth matches that of Jack (44100 or 48000). In case you are unsure how to set it up properly, press the Setup button of Qsynth, then select
