I have Jabb and want to pick up GPO and CMB too. I see GPO is up to a version three that has an ambient reverb. Since I intend to utilize the libraries together for some projects, would I be better off getting version 2 of GPO? Would it be a better blend with JABB and CMB with all dry samples?
GPO has been recorded dry and should blend fine with Jazz and Big Band and the Concert Band libraries. Ambience Reverb is a reverb plug-in that has been included with GPO since its original release. You can use it inside a sequencer (or any other program capable of loading VST plugins) to add its reverb effect to any audio track, including those from GPO, JABB, and CoMB.
Version 3 of GPO, as well as the Concert Band and the latest version of JABB, ships with the Kontakt Player 2 interface. This gives you a unified place to load all your samples.
