Hi Andi,
Thank you for your fast reply!
I'm using Sibelius 7.5 and do not dare to come near Sibelius mixer!
I'm using 3 different staves for 3 clarinets. 1 doubles Eb Cl and 3 doubles Bass Cl. But even if I use 1 staff I can't switch between Bb and Eb.
For the other woodwinds I had no trouble making instrument changes. I have 3 different staves for 3 flutes and switch 1 for the doubling piccolo and 3 for alto flute with no problem at all. I have assigned channel 1 for piccolo, 2 for flute and 3 for alto flute.
But when it comes to the clarinets i can't switch between Eb and Bb no matter what I try. And even switching between Bb and Bass Bb requires me to assign more channels for Bb Cl or else when I make the instrument change for Clarinet 3, Clarinet 2 stops sounding.
I tried to use "none" Sound Set in the Playback Devices within Sibelius and I could find a sound ID for Eb Clarinet: "wind.clarinets.eb". Is this the root of the problem? It seems that Sibelius cannot find the difference between the Clarinets and only interpretates MIDI channel assignements.
I am writting for an orchestra with the following instrumentatio: 3333-4331-tmp+3-hp- cel/pno-cds. It's a quite large orchestra so I really need to be able to make instrument changes rather than assigning an individual staves for Eb Clarinet and Bass Bb Clarinet. I'm also short on RAM (4GB) and my iMac can't expand witch is really dreadful...
Best regards,
Markus
