AU Instrument Keyswitch Workaround

AU Instrument Keyswitch Workaround

I have a virtual instrument library 8Dio Adagio Violins via Kontakt 5. Great product, however all patches are sets of articulations using keyswitches.

For my setup I have built a template using a mixture of orchestral instruments and selecting the best of each library. I am foregoing keyswitches for a one Midi track per articulation approach. However this library does not offer separate patches for each articulation and this is problematic for me.

1. I cannot preselect an articulation per Midi track

2. All articulations are loaded no matter whether I want to use them

Does anyone know a way to trigger the keyswitches in Logic Pro (which use notes in a predefined register) another way?

Ideally I want to switch Keyswitch when I select a Midi track in the Arrange menu. I tried presetting a Program change in the track settings of a Midi track (which is cabled to the AU Instrument), then adding a transformer that converted said Program change to a Note number. This did not work.

I have seen plenty of solutions to create Keyswitches from several instruments but not the other way round.

PS I am using Vienna Ensemble Pro, is there a way to do it in this?

Logic Pro, Mac OS X (10.6.8), Logic 9.1.6, Mackie D8B, Mackie MCU

Hi

(I answered this over at LPHelp, but for completeness...)

This Transformer seems to do the trick:

The Transformer is selecting incoming PC messages on any channel and converting them to KS note On events with Velocity 127. The map 'translates' the PC number to a note number, in this example (using the K5 Factory String Ensemble patch)

PC 0 = C0 (note #24)

PC1 = C#0 (note #25)

etc

The Multi Instrument is simply there so as to provide "Labels" to the PC numbers using the Patch List. A simple Instrument object would work except that you don't see names for the PC/KS selected. These names also show up in the Event List if you need to switch mid part, which is easier than trying to remember all the different PC/KS combos. Channel 1 is switched on in the Multi.

A more advanced setup might need MIDI channels to be considered.

I often enter PC messages either from my iPad or a MIDI controller, and these need to come into Logic on a channel other than Ch 1 (which can call up Channel Strip "Performances"). I have therefore 'fixed' the MIDI channel in the Transformer.
