USB Host -> connect multiple devices through usb hub?

Sort of… I’m running a computer (Mac) centric setup at the moment where this is no issue. Most of the sequencing is done with Ableton Live/Push 3. Fits my needs for now.

As a side note; besides not having separate MIDI cables, I also eliminated analogue audio cables for the synths that support USB audio. This also eliminates the hum some USB powered synths produce on their analogue outputs.
And I combine the USB audio outputs with regular analogue outputs from other synths using Apple’s Aggregate Device (Create an Aggregate Device to combine multiple audio devices - Apple Support) to create one hybrid audio interface for my Mac.
