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),
        .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
                /* .vendor_name = "Roland", */
                /* .product_name = "A-PRO", */
                .ifnum = 1,
                .type = QUIRK_MIDI_FIXED_ENDPOINT,
                .data = & (const struct snd_usb_midi_endpoint_info) {
                        .out_cables = 0x0003,
                        .in_cables = 0x0007
                }
        }
},

Clemens
