Vienna Symphonic Library

Hello everybody, 

We have just created 3 versions of the Multiport Template, and we found a way to reduce complexity by replacing the macros with "only" Transformers and using the new mode "Copy matching events and apply operation (in reverse order)" in the MIDI Environment.

Learn more about the structure of the Multiport Templates in the VE PRO 5 Manual, page 46 ff. 

These are the available templates (also attached as a zip file to this post):

• 1x16 MIDI Ports (256 MIDI Channels, 1 instance of Vienna Ensemble PRO)
• 2x48 MIDI Ports (1536 MIDI Channels, 2 instances of Vienna Ensemble PRO)
• 6x16 MIDI Ports (1536 MIDI Channels, 6 instances of Vienna Ensemble PRO)

Logic´s buffer limit in simple words:
If for whatever reason more than 256 simultaneous MIDI messages are sent from Logic to the Multiport Environment, the buffer will drop MIDI data randomly. With a lot of automation data and a huge template with many instruments playing, this number is easier reached that one might think. 

Best, 
Paul

Hi Cyril, 

I wasn´t aware of that.

Many thanks to Cyril to have proposed this improvement 

Best,
Paul

Does this mean 256 per instance or 256 for the whole environment? Is there any way to monitor the amount of midi messages?

Some clarifications:

The midi buffer size per VEPro plugin was 127 in Logic 10.0.X (and anything before it). It was increased to 511 events in Logic 10.1.

This buffer applies per process block. VE Pro uses a midi buffer size of 16384 events per block (per plugin/instance).

We have now released 3 iterations of the Multiport environment. The first version multiplied MIDI traffic by 3. The second version (combined with a later VEPro version) cut this down to 2. The last release keeps the multiplier at 2, but slightly simplifies the environment layout.

The history of maximum numer of MIDI events in Logic has thus been:

Logic 10.0 + Multiport 1 = 42 events per block
Logic 10.0 + Multiport 2/3 = 127/2 = 63 events per block
Logic 10.1 + Multiport 2/3 = 511/2 = 255 events per block

IE, your arrangement can now be 6x more bombastic than when using the first multiport version with Logic 10.0.

MIR needs to be installed on the Slave 

On the Master you put Logic 

You use the best computer as a slave as Logic does not need many resources to run

Thanks for the answer Cyril. That makes sense in that case.

Let's compare these setups:

Setup 1 (my current setup): Master i the best computer and has Logic for composition and mixing, MIR (the reverb plugin loaded on each track in Logic), lots of non-VSL stuff, no multiport; 1 VEP-plugin for each 16 channels. Slave 1 has Dimension strings on 2 VEP instances (2x 16 instruments) and slave 2 has woodwinds and dimension brass on 2 VEP instances. So there are a total of 4 multitimbral VEP-plugins loaded in Logic. VSL Percussion and other instruments are loaded on master computer.

Setup 2: Master is the second best computer. Logic for composition and summing, multiportsetup for 2 slaves (2 VEP-plugins loaded in Logic). Best computer is slave 1 and has all VSL, non-VSL (like kontakt) and MIR loaded. Slave 2 for instruments that do not require MIR, like synths, else mostly a useless slave.

So I'm trying to understand why setup 2 would be better. Is the performance in VEP better than in Logic Pro X? Are there other reasons? The only one I can see for certain is that I would get the dry/wet audio from MIR on separate audio returns.

It is less cpu intensive to use VEP

In my setup I have decide to put K5, QLSC, EXS(of course), Omnisphere in Logic and I send the resulted audio to VEP and to MIR

MIR is your concert hall so all instrument should be send to MIR. The problem are instrument like QLSO that does not have a dry signal. You need to find out if an instrument in MIR can be set as DRY !

On the other hand I have the VEP2 instance on my slave computer and it receives midi data only through ports 1, 2 and 3. Ports 4 to 48 are not sending anything to the slave. Does anyone have any idea why this might be so?

So I studied the problem a little more and it has nothing to do with the master/slave issue. The problem is the VEP 2 instance. Only the three first ports of VEP 2 instance are working no matter if I connect it to a VEP instance on my master computer or a VEP instance on my slave computer. Likewise the VEP 1 instance IS working perfectly with VEP instance on either one of the computers.
