Title: Multi USB inputs..
Post by: opus.quatre on September 23, 2017, 12:02:03 PM

Hello there..

Been documenting on TEControl products, mainly for breath controllers..
They need a class compliant device, and I believe that Preefm2 is..
I mean, I believe that I would just have to plug the Breath Controller into the Preenfm2 and blow, and the device would sent its CC2 values and Preenfm2 would understand them, and obey..
The Pedal controller seems an interesting device too..

The thing is : If I plug the TEControl module into my preenfm2's USB socket, then I have no more USB socket to plug a Kboard into.. I can still use a MIDI DIN input, sure..

But is there a way to have 2, 3 or even 459 USB sockets to control the Preenfm2 ?? You know, for example, those cards we use on computers which multiply a single USB socket into 4 sockets ?? Probably not, as I suppose they need a piece of software to manage them..

Enjoy breathing..
Thierry

there is a fundamental misunderstanding here.

the usb port on the back of the preenfm has no host facility, you can only plug the preenfm to a host (computer for example) you cannot connect keyboards or anything to it. if at all possible this would have to be added to the usb port inside the preenfm where the stick is inserted. support for usb-midi devices would be very nice indeed. Xavier, is this much work? (it would require usb hub support and usb-midi parsing)

Oh.. I see.. I took the problem by the wrong side.. I was almost sure that Preenfm2 was class compliant.. But yes, now I remember that when I had just a kboard and the preenfm2 connected, without any computer, that was through MIDI and not USB..

Oh yes !
USB OTG (switch between host and device) is very complicated.
In fact USB is complicated, which is why it's so simple to use.
