Running Multiple synths in standalone mode?

[Lyricanvas]

Hello,

Im trying to run more than in synth in standalone mode. If I open the CS-80 and send it to midi portA channel 1 it works fine. If I add another standalone Inst (i.e. ARP2600) set it to midi port B channel 1 it works but the CS-80 quits working. Any Ideas? Anyone run into this issue?

Thanks,

J
