[Csnd] Can an UDO use an optionsl array (issues)

The Csound Mailinglist

I'm trying to use an array input as an optional parameter. Take for example:

opcode test, 0, i[]
  iArr[] xin
  printarray iArr
endop

instr 1
  iArr[] fillarray 1, 2, 3, 4
  test iArr
endin

If o[] or j[] are used, Csound freezes (Android app). If p[] is used Csound runs but gives the following error:

invalid xin statement for UDO: defined 'p[]', found 'i[]'

Scott

Write two UDO’s with the same name: One udo with an array input in the argument definition, and one without. Csound should select the one to use when given the matching arguments.

Thanks Thorin.Now I recall hearing that before, should do the trick.
