[sharing] Gen.Sampler

    Hi ! My first steps into the darkness .
    Just wanted to share a Gen sample playback journey inspired by Roald Baudoux playback solution found here https://cycling74.com/forums/sharing-der-niebelungen-looper-with-gen/ . Which was very enlightening . Thank you Roald ! It get me started !
    Thanks to Peter McCulloch , for the presence on the forum . Many of your discoveries and elaborations are essential , i could gain and learn a lot with it , as most of the time your are penetrating the fields that im truly interested in.
    As well from others over the years . Thank you all for the input that is always inspiring .

    Sampler itself is a simplest sample playback engine , that has ability to loop sample region and crossfade within for more smooth and pleasant sonic results . Also provides looping forward and backward .
    No additional sample interpolation is implemented .
    Changing loop settings in realtime is not without artifacts , such avoidance would require much more CPU cycles . So i decided to make as much effort as i could to decease the amount of them instead of getting rid of them entirely . Overall efficiency is a compromise of that fact anyway ,so i decided not to add any redundant computations at this stage as the main goal was to make crossfade looping satisfying in terms of sound AND performance .
    There is a crossfading where equal power fade is computed , i did not find more efficient way than this .
    And to be fair ,im not happy with the performance of that circuit somehow . Its my first Gen patch anyway . Ive been forced to provide a few temporal clocks for index traversal while looping in crossfade, as well a phase for the cross part . i Could not find better solution for such things ,as to avoid artifacts this is only what i could do .
    I would be happy if some of you would be able to spot any weakness and maybe help to improve it as i really would love to use it on daily basis .
    And i hope some of you will find it useful as myself . This is also the reason why im posting it .

      thanks for this, it does nice sound! but the loop attribute doesn't work, i think. or did i not understand how it's supposed to happen ?

      Hello Vichug !
      im sorry , i should describe it :/ in order to use loop ,please drag loop selection on your UI waveform .
      patch updated witch description ! . also "sample drop" section will setup flonum range correctly in relation to newly dropped sample .
      Thanks !

      Hey! well i tried to drag loop selection afaik... will give it a retry !

      great do..while! if you could comment your gen code would be easier to learn !
