ok thanks Istvan and Victor for help fixing real-time!

CsoundX is a csound5 front-end application for OSX
Although it is still in proof-of-concept phase,
it may still prove useful.

Things you can do with CsoundX:
Render simultaneous MULTIPLE csd/orc/sco in real-time or to disk.
Use a generic GUI Control panel for real-time control that
  you can replace or modify with YOUR OWN INTERFACE
  using Apple’s Interface Builder application. [ see README ]

Things you can’t do with CsoundX:
Edit [ save ] your csd/orc/sco files
FLTK [ hangs CsoundX ]
