Hi DG,

Thanks for your answer.

I am not really sure what you mean

In my 1st post I said :

- 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 ?

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

and

unmeasured tremoli



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.




-> 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.

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

Ah, but on the piano the technique is not really any different, whereas on the violin that is not the case.

Hello Maya

Thanks for the details

To make a long story short I have just post you a mail with a midi file that contains a few bars of the Timpany part of "From the New world" of Anton Dvorak, can you tell me how many voices VSL VI will need to play it ?

Tempo is 136

Thanks in advance

Hi Cyril,

I will try to figure it out.

Best,

I presume you mean in an Allegro tempo? I would think if the mov is Largo this becomes a whole different story.

Just to add to this thread. I'm sure it's been said already, so if so I apologise. But when you are running Logic on a Quad G5 with VI also running, does the VI server use the two cores that Logic is not using? or does it run "with" logic and use only the two cpu cores that logic can use?

Hi Miklos,

Logic is using the 4 CPU of the QUAD but is reporting "core audio overload" when the 4 processors are reaching 50 % of load EACH [:(]

Cyril

Thanks Cyril, that gives some explanation of things and helps a lot, but my question is still whether VI runs independantly of Logic or "with it" for example, if Logic is so limited to 50% of available cpu power, is VI limtied with it too or can VI use the remaining power?
