I do not know how to answer but in any case, the audiodrum of the audya are encrypted audio files, probably compressed according to algorithms specific to KETRON (owner format) and I doubt very much that they are compatible SD90 and vice and versa Embarassed
PS: if the AUDIODRUM of the SD90 are wav format, in this case the door is can be openEd Razz since it is possible to add PATTERNS with AUDIODRUM on the AUDYA Okay
