Structure does not work for EXS users. Most of our EXS instruments do not play when opened up without troublesome readjustment of envelope settings. They have the infamous EXS Attack Sustain Decay Release envelope bug which prevents rapid auditioning of my 50,000 sampler instruments to sort through. AIR knows very well of this major bug. I only use my 160GB EXS library, therefore, my top-of-the-line version of Structure is essentially useless to me as an efficient everyday tool. The time has come to correct these many old but serious problems.
