The EXS24 has long been my "go to" becuse if its seamless inegration with Logic and its CPU efficiency. but more and more I am relying on libraries that require Kontakt and Play.. Logic does not deal all that well with multi-timbral instances as all the instruments in one Kontakt or Play multi go to one core and any CC7 automation on MIDI tracks affects the whole AU. This is why East West recommends using separate instances and with K3 soon to have the ability to aces as much RAM as you have over 5 GB, as does Play and EXS24 already, and computers with more cores getting more powerful, not using multis makes more and more sense. I prefer to work with Software Instrument tracks to MIDI tracks anyway as you can add plug-ins to them, which you cannot do to a MIDI track. There is only one drawback to my working this way. A lot of the Kontakt libraries I like use Mod wheel modulation, CC1, to switch between samples to get an effect, i.e. a brass instrument getting edgier as it gets louder, which I like to control fom my Expression pedal. Unfortunately, AFAIK, there is no way to use Logic's real time TBA to automate CC1 or CC11 on a Software Instrument track. So presently I have to create and use MIDI tracks to do this in real time with Hyperdraw (RBA). Any thoughts?
