    Hello,

    I have a question concerning the filter control in the VI. I chose the note velocity as the controller for the filter. What I do is:
    a. control click on the fader, it flashes red
    b. go to the Map control. Choose note on velocity as controller.
    Go back to the fader page and play. I see the fader move, and the filter works. Everything seems fine, until I look again at the Map control page.
    I see that Speed is now controlling the filter. I do the steps above again, choose note on velocity again, but same result after some playing. What do I do wrong??

    Greetings,

    Hi Gerard,

    I apologize for not answering your question but the filter is VERY nicely handled with a foot pedal (I use ALL the time on WW and Brass parts.) Just my opinion.

    Hello Rob,

    I will try that, thank you

    Hello Rob,

    I tried to assign the pedal to the filter. Which midi-number is used for controlling the filter-data? When I use 64 (pedal) this means I use the sustain pedal, which is a switch controller, not a continuous controller.

    Maybe I should explain that I have an LMK 3 keyboard which has a number of fixed controls like mod and pitchwheel, data entry etc., and two pedals. One is my sustain pedal (switch) and the other is free to use for what Midi data I want. That's why I want to know the midi number.

    Essentially the note on velocity is the value I want to be able use for the filter. Playing louder -> sharper, playing softer -> more muted sound.
    Problem is that VSL seems to default every time to SPEED, thus only playing 'sharply' when I play fast. This is not what I want obviously.

    It feels more natural though to hear the sound change when playing louder on the keys then by pressing a pedal to change the sound.

    I hope somebody can help with this.

    Hi Gerard,

    Yes - I meant a foot controller pedal (not sustain). Simply right click on the 'filter slider' within VI - it will turn to flashing red-orange - move your foot controller and viola' - the pedal is now assigned to the filter. [:D]

    You shouldn't do both things (perform control AND map control). Whatever you use last should override the first one.

    So in performance control when the fader is flashing red it assigns whatever control you play next. If you play a note however it just chooses "speed". That's fair enough as there is no way for it to know whether you intend speed or velocity. Actually there is, it's just that in the current version it doesn't.

    To make it react to note velocity you would have to assign this in the alternatiuve method, ie map control.

    If you assign it here (and make sure you don't override it by doing anything to filter in perform control), it will stay assigned.

    However I think there is a problem: it doesn't work! - maybe it's a bug.

    I have assigned note velocity to filter and it does nothing.

    The other answer, ie assign a footpedal, is OK, but it is a workaround to what you actually want to do. I don't see why you shouldn't be able to control the filter with note on velocity if what you want is for it to react to note velocity not a pedal.

    If it was me I would make a reasonable workaround by creating a transformer in Logic environment that transformed note on velocity to a continous controller that also also allowed the note velocity through as normal. Are you using Logic by any chance?

    But I still think there is a bug that stops note on velocity controlling the filter. I'll experiment a bit more though.

    Hello Pete,

    Thank you for your interesting answer. I understand my mistake. I managed to make my pedal work for filter control, but it feels better to use the keyboard for this. I use Logic. I never used this transformer before, but it sounds good! I will try it.

    Maybe I can ask a second question: the first item in the map control page is 'expression'. I understand that this is essentially a volume control.
    Am I right?
    It will be difficult to have enough controllers to map all these things in the VI!

    I am currently working on a dedicated Vienna Control for Logic.

    I thought I'd add a module that does what you are after so there is a beta version of just the note velocity transformer for download at the bottom of this page if you want to try it out:

    http://www.petethomas.co.uk/logic-vienna.html

    It has a switch to switch between thru and transformer. It transforms note velocities to CC74 which controls the filter fader, but note velocities still go through as well. There is a fader to limit the range of the filter also.

    Re: expression. My understanding is that it does indeed control volume of the sample, but it's best not to confuse with CC7. If you use CC11 (the standard continuous controller for expression) it affects the loudness of the whats coming out of Vienna, whereas CC7 (volume) will affect the fader on the Audio Instrument in Logic's mixer.

    I prefer to use a velocity Xfade in vienna much of the time as often you end up with a more realsitc sound because you are crossfading to samples recorded at different velocites - you get closer the exact sound the player played louder if you see what I mean.

    Hello Pete,

    I will certainly try your controller, it seems to be exactly what I need!
    Thank you very much for this help.
