    Hi

    I was reading the test made with VI on Mac

    @Another User said:

    Maximum Vienna Instrument instances: 24 (CPU 90%)
    Maximum Samples loaded: 45000
    Maximum polyphony: 300 stereo voices / (CPU 70%)


    Why is there is a different CPU load (70 and 90 %) ?

    I have a few questions :

    - Do you have the same test for a Quad G5 2.5 with 8 GB ?

    - I supposed that the disk I/O are very important :
    -- have you done tests with a Raid 0 ?
    -- if you put the lib on a internal SATA what gain would you expect v.s. FW 800

    - Is VI able to use my 8 GB of memory ?

    - I am currently using QLSO Platinum and I have big problems with fast parts as for a violin tremolo or a tympani roll it will used up to 150 voices, will VI have the same problem ?

    - if you have 3 lines of a Violin in a piece, will VI share the samples between the instruments or will you have to load the same samples 3 times

    Cyril:

    mon ami:

    I've been watching for responses to your questions as well. You make some very important observations to the test results that are indeed confusing as they appear.

    Is there anyone who can address these questions? I'd like to know, too. Thanks.

    You´ll need to load it again but VI will share the samples in RAM.

    sTA would be the preferred location because
    - it is a more direct connection to the bus
    - most sATA drives provide NCQ (less seektime)
    - in FW-enclosures mostly sit pATA drives
    - you leave out 2 controllers (bus to FW, FW to pATA)

    and remember: only a CRAY can run an endless loop in just three seconds.

    Hello Maya,

    Many thanks for your answers.

    @Another User said:

    In our Viennna Instruments, Timpani rolls are already recorded as rolls. So playing a timpani roll + corresponding release sample will use 2 voices (unless you activated velocity crossfade).
    I am not sure but I ´d assume there are recorded rolls in QLSO too (?).


    QLSO has tympani roll too but it is not the way to write music, as they do not follow the song tempo ! [:O]ops:

    Are VI's tympani rolls following the song tempo ?

    I will use the following abbreviations :
    Left hand = L
    Right hand = R

    If you want to play rolls RL or LLRR or LLR or RRL it's impossible to program. It is better to write the roll note by note, same for the violin tremolo.

    So can you answer again to my question :

    - I am currently using QLSO Platinum and I have big problems with fast parts ; a violin tremolo or a tympani roll it will used up to 150 voices, will VI have the same problem ?


    As I have many problems with QLSO Platinum I am very chilled
    I dont want to spend thousands euro, and have the same problems again.

    Sorry more questions :

    - Can you run one Logic VI AU and one VI Standalone using IAC on the same computer ? can they share memory ?
    - How much more greedy is VSL VI compared to VSL EXS and VSL K2 ?
    - I have a G5 2x2 3.5 with a raid of 6 raptor and a Quad G5 with 8 GB ! what can I expect with this configuration ? can I launch a 2 or 3 VI standalone
    - In VI can you chose to have some instruments in memory or all the instruments are streamed to disk
    - Has VI it's own virtual memory handler or do you use the VM handler of OS X ?
    - Do you need 4 or 6 computers to play a full orchestra ?
    - In the demo section of VI there is the "Mahler's Symphony No. 5 - III. Scherzo", what configuration has been used, did the user had to freeze any tracks ?
    - Are you thinking to have a demo limited version of VI ?


    This is all for today

    Best regards

    This is not planned.

    Hello Cyril,

    rolls are tempo-independent. In our rolls you don't hear the strokes unless you are using a patch with hard mallets. Therefore it's not necessary to have rolls for different tempi.
    Timpani-rolls are always played hand to hand (= alternating). It is not possible to program our rolls LLR, LLRR or RRL. To be honest I also don't see any use in programming it that way.

    My roll and my violin staccato are tempo dependent, sorry ! but this is my problem [;)]

    So will a fast roll or a violin staccato use 150 voices like in QLSO ?

    Hello Maya,

    You do not like my name ! My name is Cyril, not Crystal [;)]

    Thanks for your detail answers.

    [quote=Maya]Dear Crystal,

    Please note that VI standalone is not multitimbral and you can only launch one instance of it (= 1 MIDI channel). Because of this it will be necessary to run them in a host like Rax, Blogue bidule or in a sequencer like Logic Pro.

    [quote]

    So if I have understand, if I have 3 instance of key switched violin I will need to load the samples 3 of the violin times, i.e. the memory will not be share between the 3 instance of violin.

    If I start to buy VI what are my guarantee if I am not happy with it ?

    VI will of course share memory whenever identical patches are loaded.

    Concerning return policy, I need to ask our sales people first.

    Loading extra instances does not increase the memory used by the samples (in other words they are loaded once) but the extra instance of the actual VI player does use more memory.

    Edit: Too slow........... [:(]

    Regarding your need for tempo dependant violin staccatos, I am not really sure what you mean, as surely the staccatos will be played at the speed your sequencer is set to? As far as tremolo is concerned, this is not tempo dependant (broadly speaking) so the tempo of your track should make no difference. If I have misunderstood please let me know and I'll try to help further.

    Cyril,

    it might be interesting for you that my collegue Marnix Veenenbos will be presenting Vienna Instruments at the "Salon de la musique et du son" in Paris soon->

    http://www.salon-musique.com

    You´ll find him at the booth (stand à la foire) of BestService (G113).

    I have no knowledge of bidulle or AUlab, but there is no problem in Chainer or V-Stack.

    As each Vienna VI is limited to 64 violces it is extremely unlikely that it could use "up to 150 voices". Isn't the number of voices governed by the number of notes that you play (other than xfading instruments)?

    When you play the same part with an EXS a note will use from 1 to 4 voices, QLSO has release tails that are causing a lot of problems on fast parts.

    Hey Cyril,

    Our inhouse composer - CK - who visited his orchestration and instrumentation lessons (Prof. Sevsay) constantly (unlike me) during his studies of composition just informed me about the following details on tremoli:

    Actually there are two different terms and signs for tremoli

    measured tremoli

    <a href=http://members.chello.at/tozo2003/best_trm1.png">http://members.chello.at/tozo2003/best_trm2.png

    and

    unmeasured tremoli

    http://members.chello.at/tozo2003/unb_trm.png

    Unmeasured tremolo means for the musician that he should play the same note as fast as possible (as repetition).

    Measured tremolo means that the musician should play twice as fast as written. 1/8 will become a 1/16.

    http://members.chello.at/tozo2003/j.williams.png


    http://members.chello.at/tozo2003/best_trm1.png -> this sign for measured tremolo means the musician should play four times as fast (and is sometimes interpreted as an unmeasured tremolo).

    A measured tremolo is "in tempo" unlike an unmeasured one.

    CK suggests to use "perf-reps_spi" for Strings and "perf-rep_fast" patches for timpani in order to get a measured tremolo. In case that you like to accentuate certain parts of a measure he suggests to use our recorded rolls and to a add single note.

    (see also http://www.music.vt.edu/musicdictionary/)

    To be perfectly accurate a "measured tremolo" is not actually a tremolo, and is technically produced very differently [H]
