Midi sync and sample beatsync

Hello, at first sorry my english.

Please help me with my 2. problem I use Renoise 3.1.1 64bit:

I use sample loops with beatsync set for 64 lines and its was fine.

When i need enable slave the transport midi master to sync with my friends gear, sample loops not sync.

I try to set sample loops with beatsync set for 63 lines its seems Ok but tell me please WHY?

How can i map phrase to my midi controller (ipad OSCTouch buttons)

I know it is mapped to piano keys but i dont use keyboard in my live set.

happy day with Renoise
