Thanks Hitman for your opinion. The Korg Tr gives me 16 different sounds in 16 tracks in Sequence Mode with 62 voices of polyphony. The real problem is that you can't handle different effects for each sound so they lose their original configuration and the sequence effect is always applied to all with little variations. At present I use its drums and some style instruments together with 2 right hand voices. I reassigned the best sounds of the Tr in one bank which are controlled via midi from the PSR everytime I change the style and voices. But the PSR doesn't allow me to midi off local instruments within the style.
