    Is there a way to meassure how much of the VI's polyphony is being used?

    After I made some string instruments with layered patches I'm getting quite a few drop outs when the entire string section plays. I'm trying to locate the problem...

    Thanks

    Hi Christian,

    I don't know if your question's still relevant - sorry for the delay. The polyphony use depends on whether you work with velocity crossfading. If you do, each note of an instrument will take as many voices as there are velocity layers in that Patch - added up for layered patches, of course. Also, playback is affected by how many "new" notes there are. I sometimes get dropouts when I play a piece for the first time, the second run goes smooth.

    However, I think that's more an issue of disk performance. It's not so easy to reach the 64 voice limit per VI instance just with strings even if they are layered.

    Kind regards,

    Perhaps Christian was looking for a numerical read-out, as found in EXS instances. I know I have wanted something like that as a diagnostic.

    Yes, un-selecting velocity cross-fading can save a whole lot of voices.

    Hi Christian,

    My reaction is probably way too late, but I was just going through the forum
    looking for solutions to the same problem you described.
    And guess what: I've got it too-[:)]

    Loaded: 7 patches from the String orchestra
    Matrix: 7 horizontal cells with each a different patch
    Mod Wheel controls horizontal span.
    Pitch Wheel controls velocity X-fade

    Okay, when I play a chord I get a lot of drop outs too.
    Even when I play only two notes simultaneously.
    Especially sensitive towards this is the 04 Strings_sus_vib patch, probably because it has 4 layers.

    Nevertheless, 2 notes x 4 layers x 2 for stereo is only 16 voices, no?
    So I wonder what's causing this.
    It happens also a lot when I switch from one patch to another horizontally.
    Probably because the previously played notes from previous patch are still in buffer, I guess...?

    Is there any way to adjust settings to get it better?

    Thanks in advance!

    Exactly - I ended up bouncing it! Something I havn't done for 3 years!

    Hi Christian,

    Herb gave some interesting answers regarding the use of voices, yesterday at the bottom of the thread: "crossfading and polyphony", although you probably already read it.

    Cheers,
