    GrandOrgue ODF attack/release questions

    Can anyone help explain to me the following section of a GrandOrgue ODF?


    Pipe001=Rorflojt8\036-C.wav
    Pipe001LoadRelease=N


    (So is this the sustained sound sample?)


    Pipe001AttackVelocity=86
    Pipe001AttackCount=2


    (What is the relationship of Pipe999AttackVelocity to Pipe999Attack999AttackVelocity?)


    Pipe001Attack001=Rorflojt8\036-C__1.wav
    Pipe001Attack001LoadRelease=N
    Pipe001Attack001AttackVelocity=42


    Pipe001Attack002=Rorflojt8\036-C__2.wav
    Pipe001Attack002LoadRelease=N
    Pipe001Attack002AttackVelocity=0


    (What is the effect of Pipe001Attack002AttackVelocity=0?)




    Pipe001ReleaseCount=5
    Pipe001Release001=Rorflojt8\rel99999\036-C.wav
    Pipe001Release001MaxKeyPressTime=-1


    Pipe001Release002=Rorflojt8\rel99999\036-C__1.wav
    Pipe001Release002MaxKeyPressTime=-1


    Pipe001Release003=Rorflojt8\rel99999\036-C__2.wav
    Pipe001Release003MaxKeyPressTime=-1


    (I assume Pipe999Release999MaxKeyPressTime=-1 is infinity? Does this section indicate that one of the three releases will be selected at random on a "long" keypress?)


    Pipe001Release004=Rorflojt8\rel00200\036-C.wav
    Pipe001Release004MaxKeyPressTime=200


    Pipe001Release005=Rorflojt8\rel00400\036-C.wav
    Pipe001Release005MaxKeyPressTime=400


    If for some reason I wanted to eliminate the attack and release variability which samples would I use? How would the ODF look?

    Hi Tom,
    I didnt use the velocity parameters in GO myself, but I might still give you en explanation referring to the GO-Helpfile:

    What is the relationship of Pipe999AttackVelocity to Pipe999Attack999AttackVelocity?
    => the first one decides whether that pipe used at all, if you press the key very soft, that pipe might not be in use. This is my be usefull if you have a special rank, like a drum or so, and you don't want to play the drum every keystroke, only the very hard ones. I once read about "second touch" and this must be the implementation parameter. The second thing (Pipe999Attack999AttackVelocity) decides which of multiple attack samples shall be used. Your example has got attack samples.
    By the way: There ist rare use of multiple attack sample, I've only found them in teh green positive by P. Grabowski.

    What is the effect of Pipe001Attack002AttackVelocity=0?
    => this is the minimum velocity to use this attack sample. 0 is the lowest number, so this attack sample is used even with the lightest touch...

    I assume Pipe999Release999MaxKeyPressTime=-1 is infinity? Does this section indicate that one of the three releases will be selected at random on a "long" keypress?
    => You are right!

    If for some reason I wanted to eliminate the attack and release variability which samples would I use?
    => You could use any of the "infinite" release sample and have no attack sample at all. Longer release samples are of better use as the short ones, because looping occurs not that often. You can listen to the .wav files using any kind of music player: Some files don't sound at all, they can be skipped, and of the ones you can here you choose one you like.

    How would the ODF look?
    => the ODF will look like that:
    Pipe001=Rorflojt8\036-C.wav

    Hope that works for you,
    Oliver

    Also look at the ODF reference in the GO help (and enable strict ODF mode for error checking).
