answer of zoom #8

Is there a way to understand if the zoom has received the sent command via the USB? For example, if I send 0xc012 I ask the ZOOM to select patch 12. But it is not said that he received the command and therefore executed it. How can I be sure this has happened? Normally the devices that receive such commands (eg solar inverters) respond "ACK" (acknoledge) or "NAK" (not acknolodge) or a return code that shows us the same thing in practice. How does the ZOOM work? P.S. This request is good to understand if ZOOM in connected to USB too.

Unfortunately, zoom does not respond to requests such as patch selection. In order to know whether the command has been accepted, it is necessary to send "Request Current Program [0xf0, 0x52, 0x00, 0x58, 0x33, 0xf7]" etc. separately to poll the current status.
