MU step sequencers framework 4 tracks only???

[Jo Borges]

I tried to ask in troubleshooting but maybe here is a better place to ask since I didn't received any answers there.

I could run via Mu frameworks up to 4 tracks of Mu step sequencers and, besides some visual feedback glitches, all goes really fine. But when I try to add another track, the Lemur stop to receiving information. even if I reboot and reload the project to send information again, iPad can't receive the info with more than 4 tracks of MU stepseq. is that a technical limitation of how MU is implemented or is that a bug?
