Copying midi bass lines

  I am working on a project involving  10 midis I played using a piano sound. I want to copy only the bass parts of the files and use those to add another part...Would I copy the entire track and delete all but the bass parts or is there another way to thin the higher notes and retain the bass notes in midi?

    I think if you go inside the PRV, you can select the notes you wish to delete. Therefore, select all the notes above the bass-line and presto! (Mind you, I do this in another app, but it should work just the same)

    Okay, I just did it. (A long string of C chords with C in the bass.

    Hold down the Shift Key when selecting notes.

    I selected all above that string of notes and hit "Delete."

    I've done this many times, usually to split a piano MIDI track into separate tracks for left and right hand parts.

    Just clone the track and use Rus' method to delete half the notes from the original and half from the clone. To remove all but the low notes, drag your mouse down the keyboard in the PRV from the crossover note on down, then hit Del.

    I also recommend that you make a backup of the original MIDI track just in case. Just mute, archive and hide it. Just in case.


    All else is in doubt, so this is the truth I cling to.

    ^ My you make that sound so "complicated" bitflipper, I had initially written about cloning the track! This my be a very egregious generalization, but I wonder how many people no matter how seasoned do that?

    Seriously, as an alternative to his method. if you really want to take care of this problem: If your track is on the grand staff, modify the Middle C split point. (You have to be careful here, but it will also work)

    Start by finding your fundamental bass note and decide on the range. Once this decision is made, go into Layout in the Staff View and change the Split point < or > C5. Bass notes by default are B4 and > treble notes are C5 and <.

    This is also helpful when scoring where the 8va/b clefs are used respectively. No sense in performers seeing 8-12 ledger lines when the same result can occur seeing 0-4. (Unless the composer's uber-picky! lol)

    I'll stress again, be careful!

    When I record midi tracks, I generally have a piano track and a separate bass track that just does bass. Plus whatever other midi tracks happen to be in the song. 

    Normally, the bass line the piano is playing will not work as the bass line in the songs (for me anyway) so I really don't consider pulling them out to do something else with them. 

    I'm interested in hearing this tune when it done. I'd like to hear what you are doing.

     Thanks guys, I wanted to get a nice string background and the bass line seems to be the best way to place the part correctly. I like the technique bit uses to get a stereo part. I appreciate the advice guys!
      The timing in the music is intentionally varied to convey mood and so I didn't quantize. This seemed to be the best way to place low string parts. I will likey remove the bass piano parts after I get the other parts in place.

     Herb, I'll send you a link when I'm done.  10 seperate songs...about 20 minutes of material. Thanks!
