Speed up a MIDI record

Recommended Posts

Hi, is there a way to speed up a midi record via px560?

Use case scenario:

1) record a midi at a low bpm

2) speed it up -> make its speed higher

3) record a WAV file while the midi is playing at a higher speed.

Thank you!

Sure-as long as you understand how to import a midi file into the PX560, if you are asking about an external midi file on your tablet, phone or computer. Once imported you can change the tempo in the usual way you set tempo in the midi recorder/song recorder of the PX560 if you wish to keep that tempo, its a little tricky because tempo will only be recorded in the system track. i think this is done automatically when you import a midi file but I'd have to check the manual again to refresh my memory. You don't need to record the tempo though-it will play back at whatever tempo it was originally playing from your computer or whatever source you are using. This isn't answering your question completely yet, but you must do this first if you want to convert it to a wav file recording. Otherwise all you have to do is change the tempo of the midi file with the PX560 tempo setting. The final answer-all you have to do now is hit play from the midi recorder of the PX560-after you put the audio recorder into record mode-this will now create a wav file recording from within the PX560's audio recorder, which is a separate recorder from the song/midi recorder. Again study the manual if you are not clear what the different recorders are and how to use those. This wav file will end up in the "musicdat" folder of your PX560 thumb drive, and you can take that wav file and save it to your computer. Another nice feature about this wav file-if you install "Audacity"-a free open source audio editor for Windows-you can load the wav file into that-and not only change its speed, you can change the pitch of the entire track or midi file you saved as a wav file, add effects etc. And-Audacity can export the wav file to an mp3, a smaller file than the wav file for playing on a smartphone, tablet or media player.

The easiest way is to start the WAV recording, pause the MIDI at the beginning, increase the tempo, and then touch on Play. But if the MIDI file has tempo changes I'm afraid this will not work, as that will override the tempo you just set... If the MIDI has tempo changes, maybe using a MIDI editor on the PC is your best option.

And about Audacity, it's a great tool, but nothing done on the wave file will be the same as playing at a faster speed, as of course each instrument will sound different when sped up (even keeping the pitch). Just like changing the pitch is not the same as transposing, although if the pitch change is small, the difference will be subtle.

For a MIDI recording made entirely on the PX-560, these are the options:

 

1.  Record a new system track again.

 

Tempo is stored in the system track as a MIDI event.  Unfortunately the 560 does not feature event level editing, so the only onboard option is to record the track again.  You would need to export the song as SMF format and edit the event on a computer.  In the export process, the system track is converted to solo tracks as long as the MIDI recording has empty solo tracks.
