Hi all
I am interested in buying a midi keyboard plus some "device to get midi
signal on my computer".
I was looking on the roland/edirol website, since I heard that hw from
that brand is usually well supported by Linux, when I found the Cakewalk
A-500S USB Midi Keyboard, that seems quite interesting to me.
Does anyone own one? If so, I'd like to ask the owner(s) some details
about the compaitibility of this device with Linux, if everything works
well or there are any known issues / lacks of functionality; I see an
USB connector on the side: when connecting to a computer, I guess that
it should be recognised directly as a Midi device? Or I need a USB Midi
interface, like the UM-1G or similar?
Best regards

I've just bought an A-800Pro. It doesn't seem to work with Linux out of
the box, but it works fine with USB advanced mode disabled.
I think making it work in advanced mode should only require a trivial
kernel patch (hardcoding the USB model number as it was done for the
Edirol PCR series midi controllers, now replaced by the Cakewalk A-PRO
series). I didn't try that yet.
The A-Pro keyboards can be configured to work as USB-midi interfaces for
connecting midi equipment to the computer via the midi in and midi out
sockets, besides sending midi codes via USB from the keyboard and
controls.
The A-300Pro and A-500Pro work the same way. I'm not sure about the
A-500S: you should download the manual, study it and then
try-before-you-buy... unless somebody else comes up.
Ciao,
Guido

Okay, this should work for all the "Pro" keyboards. I'd guess the 500S
does not have as many MIDI ports ...
Try adding the following entry to sound/usb/quirks-table.h or usbquirks.h:
{
/* has ID 0x0110 when not in Advanced Driver mode */
USB_DEVICE_VENDOR_SPEC(0x0582, 0x010f),

}
}

I've had some problems with my roland edirol pcr-500 - the built in usb
midi sort of works but there's a small but noticeable random delay
between pressing a key and hearing the note. I managed to cure this by
using the built in midi port and switching to a separate midi to usb
card, but obviously this isn't ideal.
