In the third photo of the original post in this topic, is that a Focusrite Scarlett under the Zynthian Black Pearl? I ask because there have been problems reported with Focusrite Scarlett Solo in other topic(s) Focusrite Scarlett Solo - #8 by rod_silva.
If it is Focusrite Scarlett what full name and model number is it?
Did you have to do anything special to get it to work with Zynthian?
