Analogue-sequencer

Hi Colin,

for investigation I decided to use some midi filtering from the merge  
box now only going thru is 'note & real data' (clock, start/stop)
filtered out are: PrgCh.,Pbend, Preasue, CC, EXL, common.
I'll report if I still get the freezes with that change.

Of course for any future P3 system update I'll connect it to the RME  
midi ports anyways that are not involved in the merger/filter path.

cheers,
henry

Who is general failure? And what is he doing on my harddisc?
