Another way around the variable problem, a particularly robust one, is this:
Never thought of using it for ssh. I wonder if it iterates all variables as expected. I will give it a try!

Also, "${ARRAY[@]}" is a safer way to expand an array, because it splits upon elements, not spaces. It works for commandline arguments too. Also, your loop can be simplified quite a lot. How about this:
Thanks. Your improvement advice actually reflects my running script (more or less )
I kinda messed up in trying to keep the example script simple
I can not for the life of me figure out how to iterate over this array

afquery
AFQUERY(3)AFQUERY(3)NAME
afQuery, afQueryLong, afQueryDouble, afQueryPointer - query the capabilities of the Audio File Library
SYNOPSIS
#include <audiofile.h>
AUpvlist afQuery (int querytype, int arg1, int arg2, int arg3, int arg4);
long afQueryLong (int querytype, int arg1, int arg2, int arg3, int arg4);
double afQueryDouble (int querytype, int arg1, int arg2, int arg3,
int arg4);
void *afQueryPointer (int querytype, int arg1, int arg2, int arg3,
int arg4);
PARAMETERS
querytype can be one of the following:
o AF_QUERYTYPE_FILEFMT
o AF_QUERYTYPE_INST
o AF_QUERYTYPE_INSTPARAM
o AF_QUERYTYPE_COMPRESSION
o AF_QUERYTYPE_COMPRESSIONPARAM
o AF_QUERYTYPE_MISC
o AF_QUERYTYPE_MARK
o AF_QUERYTYPE_LOOP
arg1, arg2, arg3, and arg4 are integer selectors whose meaning depends upon querytype.
RETURN VALUE
Upon success, afQuery will return a non-null AUpvlist value. Upon failure, afQuery will return null while afQueryLong and afQueryDouble
will return -1 and afQueryPointer will return null.
Pointers representing character strings are owned by the Audio File Library and must not be freed; all other pointer values must be freed
by the caller.
DESCRIPTION
For AF_QUERYTYPE_FILEFMT, the following selectors are valid values for arg1:
AF_QUERY_LABEL
Request a short label string for the format (e.g., "aiff").
AF_QUERY_NAME
Request a short name for the format (e.g., "MS RIFF WAVE").
AF_QUERY_DESC
Request a descriptive name for the format (e.g., "Audio Interchange File Format").
AF_QUERY_IMPLEMENTED
Request a boolean value indicating whether the format is implemented for reading and writing in the Audio File Library.
AF_QUERY_ID_COUNT
Request the total number of formats implemented.
AF_QUERY_IDS
Request an integer array of the id token values of all implemented file formats.
AF_QUERY_COMPRESSION_TYPES
Used with the selector AF_QUERY_VALUE_COUNT in arg2, this will return a long integer containing the number of compression schemes
available for use within the format specified in arg3. Used with selector AF_QUERY_VALUES, it returns a pointer to an integer array
containing the compression id values of the compression schemes supported by the format specified in arg3.
AF_QUERY_SAMPLE_FORMATS
Used with the selector AF_QUERY_DEFAULT in arg2, this will return the default sample format for the file format specified in arg3.
AF_QUERY_SAMPLE_SIZES
Used with selector AF_QUERY_DEFAULT in arg2, this will return the default sample width for the file format specified in arg3.
For AF_QUERYTYPE_INST, the following selectors are valid for arg1:
AF_QUERY_SUPPORTED
Request a boolean value indicating whether the file format in arg2 supports instruments.
AF_QUERY_MAX_NUMBER
Request an integer value indicating the maximum number of instruments supported by the file format in arg2.
For AF_QUERYTYPE_INSTPARAM, the following selectors are valid for arg1:
AF_QUERY_SUPPORTED
Request a boolean value indicating whether the file format in arg2 supports instrument parameters.
AF_QUERY_ID_COUNT
Request an integer value indicating the number of instrument parameters supported by the file format in arg2.
AF_QUERY_IDS
Request an integer array containing the instrument parameter values for the file format in arg2.
AF_QUERY_TYPE
For the file format in arg2, request the type of the instrument parameter in arg3.
AF_QUERY_NAME
For the file format in arg2, request the name of the instrument parameter in arg3.
AF_QUERY_DEFAULT
For the file format in arg2, request the default value of the instrument parameter in arg3.
ERRORS
afQuery can produce the following errors:
AF_BAD_QUERYTYPE
The query type is unsupported.
AF_BAD_QUERY
The arguments to the query are bad.
