Multi Sample Advanced usage

[synthark]

I'm a newbie (evaluating FlowStone) trying to use the "Multi Sample Advanced" audio module. I've connected it to "MIDI In Select" and "DS Out" modules and successfully loaded an SFZ file (I can cycle through the displayed waves). However, the selected wave does not sound when triggered by a MIDI key. I've checked the low/hi key settings in the SFZ. I couldn't find any documentation on this module, since it isn't a primitive. Any ideas?

BTW, the example "Music Synthesizer" works fine when I set the "MIDI In Select" and "DS Out" modules similarly, so I don't think it's a MIDI or audio output issue.

Silly mistake ... I was connecting poly to mono without using a combiner.
