The Audi Switcher does two things at the same time: (1) Switching an audio stream (if there is one - with virtual instrument there is no audio input, just MIDI input). (2) Deactivates all modules connected to other output tags than the one selected (by MIDI Pro Change). --> Mono/Stereo You only need a stereo input Audio Switcher if you play a stereo signal into two two L/R panned inputs of your audio interface. Over here I have no such instruments. All my analog input instruments are mono: guitar, sax, flute, EWI synth. But I do A LOT OF STEREO though, but not before the switching. All stereo treatments happen after the output tag - that's the big advantage in using the Audio Switcher object! It lifts hundreds of synths and effects off the CPU when not in use. And you are wrong about the number of Audio Switcher outputs, I opened Bidule to check and have an Audio Switcher with 128 outputs right here on my screen. This means you can use it for a complete 128 patches setup - use all MIDI Program Change numbers available on one MIDI Channel. Over here just 20 patches is perfectly enough for me, and then I'm even blending both audio input patches and MIDI driven virtual instrument synth patches. Another useful Bidule group is the "Tail Preserve Module". It goes into action when you kick your MIDI Program Change pedal to go activate a new sound patch. The Tail Prerve Module then listens to the audio level coming out the old patch and only fades it out after the old patch has silenced. On my Bidule setup I use this to jump between patches with very long decay/release, reverb or delay and they are all hanging in the air until their sound fade out. When setting it up in Bidule this works much better than the corresponding function in MainSTage, becaue mainstage doesn't have an active algorithm listening and adjusting, it only has a preset of a given number of seconds to keep old patches active after leaving them for a new patch. Here's a suggestion: If you and I happen to own the same virtual instrument I could set up a simple Bidule template and send to you. It would then automatically swap my MIDI port and Audio interface for whatever you have on your system. Then I could also include the Tail Preserve Module, because it's not default, someone at the Bidule Forum made it for me when I brought up a discussion there if that was possible to program in Bidule (I still don't know how it's programmed, I'm too busy using it). How about that? Here are a list of stuff I have on my system: --> Virtual Instruments (AU, VST Mac, VST Windows): Alchemy (only Mac) Cameleon 5000 Arturia Moog V2 Albino 2 Albino 3 All the Pluggo synths Crystal (by Green Oak Software) Stylus RMX --> Effects Alll the free Apple effects (about 20 different effects) Sonalksis SV-315 Sonalksis SV-517 Augustus Loop (by Expert Sleepers) Crossfade Loop Synth (by Expert Sleepers) SoundToys complete Native Bundle (6 effects) Ok, so if you at least have one effect and one virtual instrument that I also have I could make a template for you to study. Then you can decide if you want to put the time into setting up more patches as you like them.
