How do I play multiple softsynths simultaneously?
I. With Logic 5.x and up (having the I/O plug-in): For those of you who have wanted to be able to play/layer multiple softsynths live, this is the procedure: Macintosh: Create a neutral object, like a Monitor, in the Environment, and cable it to all the Audio Instruments you want to play simultaneously. Select the Monitor, and check its Icon checkbox in the parameter pane (left side of window). Insert the I/O Plugin on each Audio Instrument except the one to which you cabled first. Set an Input and Output on each I/O Plugin (i.e. don’t leave I/O at the default “—” settings), and finally bypass the plugin. Assign the Monitor to an Arrange track, and hit Play or Record and play your multiple softsynths in realtime. Note: Logic has to be playing for this to work — in Stop mode, nothing happens. Windows: The same instructions as above, except for #2 above: you need to place the I/O Plugin on all Audio Instruments, including the first one. This procedure also allows you to change AI trac
