Spectroscopy with Hadrons Beams at COMPASS

Following numerous interactions with the SPSC in 2007 we review projected capa- bilities of the COMPASS spectrometer in the field of light hadron spectroscopy. The paper describes in detail a full simulation with subsequent partial wave analysis of two final states for central production. Both, neutral and all charged states can very well be observed and analyzed within COMPASS. In addition we show the result of a full partial wave analysis of data taken in the pilot run 2004 using the diffractively produced $\pi^+\pi^-\pi^-$ final state. The results agree remarkably well with previous data taken an BNL. We also vaticinate the physics data sample expected for 2008, using projected beam times for different reaction mechanisms.
