    Hi,

    Is there any way to select a specific part of a loop to playback in real time using midi? Right now I have only found that I can do it using the mouse pointer or by pre programming parts through Slicer. I got a response a few years ago through email that this could be solved via a makro. Is it possible for you to create an example macro for this?

    Thanks!

    Hi Daniel,

    I’m going to send you in separated answers 2 macro examples that could to the job.
    You’ll just have to create new macros in logelloop and to copy/paste the codes
    I hope it will be helpfull.

    Best regards

    Gwenole

    //This macro will recall a slicer step previously stored
    //by presing a midi note controller routed on the Macro Midi Variables.
    //You’ll just have to adress your midi keyboard to the midiv_ntv1, 2,3,…
    //in the project configuration menu > Midi > Variables for macro and to program your slicer steps with the desired
    //time selection.

    DoRepeat

    If {$midiv_ntv1$ > 0}

    SlicerStepLoad 1

    EndIf

    //Copy here up to 8 If to EndIf lines and just change the number of the midi ntv and the number of the slicer step load

    If {$midiv_ntv8$ > 0}

    SlicerStepLoad 8

    EndIf

    Sleep 100

    While true

    //This macro will recall a specific part of a loop via midi
    //by presing a midi note controller routed on the Macro Midi Variables
    //You’ll just have to :
    //- adress your midi keyboard to the midiv_ntv1, 2,3,… in
    // the project configuration menu > Midi > Variables for //macro
    // Set in the macro below the TrackLoopBeginAt and TrackLoopEndAt value, which means the beginning and the end
    // of the specific part you wanna recall.
    //You can duplicate this macro and assign other midi notes by changing
    //in the macro below the values of the $midiv_ntv $ value

    DoRepeat

    If {$midiv_ntv1$ > 0}

    TrackLoopBeginAt trk1 0

    TrackLoopEndAt trk1 20000

    EndIf

    Sleep 100

    While true

    Thank you Gwenole for your examples. They will be of great use when recalling specific predefined parts of the loop!

    Is there also a way of modifying TrackLoopBeginAt and TrackLoopEndAt in ‘real time’ using for example two rotary knobs if you want to enlarge/minimize the loop/slicer window in a live performance without predefined loop windows? Basically, the same way you can using the mouse pointer today. Thanks again!

    Regards

    Here is an example Macro I got from Philippe that solves my question above:

    DoRepeat

    MessageMain $midiv_cc1$
    TrackLoopBeginAt trk1 {scale($midiv_cc1$, 0, 127, 0, $current_loop_duration_samples$)}
    TrackLoopEndAt trk1 {scale($midiv_cc2$, 0, 127, 0, $current_loop_duration_samples$)}
    Sleep 50

    While true
