  • Number of voices in the Vienna Instrument

    Hello,

    In the Q en A I read this:
    Q What is the polyphony of Vienna Instruments?

    A Each instance of the Vienna Instruments VST/AU plugin, as well as the stand-alone
    player, can play 64 voices.

    Does that mean that it can in total 64 different articulations per instance, or 64 notes played at one time? (which does not seem to much to me).

    Greetings,

    Gerard Beljon

    Each instance can play 64 stereo voices at one time (but you can have as many instances as your computer can handle). You may think that this doesn't sound very much, but even if you had 4 velocity levels all playing at the same time with 2 extra stacked instruments with the same number of velocity levels this would only be 12 voices. Playing a 2 note chord would bring you up to 24. I can only see this being a problem with instruments that have a long decay such as the harp, but even then it is unlikely that you will run out of voices.

  • I am not getting very good polyphony when using VI in host applications

    I have 13 Instances VI hosted in Logic Pro on a G5 dual 2.5 with 8GB RAM. VSL Server is using 2.45 virtual and 2.7 GB real for RAM. My VI instances contain patches from Brass 1&2. My sequencer is sending MIDI to this host G5 via Midi over LAN (MOL). The host G5 has a MOTU 2408 connected to it and audio is coming back to the sequencer computer via light pipe (to another 2408 hooked up to sequencer). Logic's i/o buffer is all the way to 1024, 64 busses is off, Max audio tracks is 4.

    When I sequence triads across horn, trumpet and trombone, I get crackling in between the first chord and the second chord (this is only 9 'voices')...I know the releases are overlapping so it is at least 18 in reality. If I turn release samples off, my host G5 can play these 9 notes with almost no crackling, just barely usable.

    If I put all 9 notes on one one VI instance there is no crackling
    If my VI instances are hosted in my sequencer there is considerably more polyphony.
    I have substitued RAX and Blogue Bidule as the host app and had very similar if not identical results.

    Any thoughts?
