The fundamental changes +introduced for supporting MIDI 2.0 are: + +- Support of Universal MIDI Packet (UMP) +- Support of MIDI 2.0 protocol messages +- Transparent conversions between UMP and legacy MIDI 1.0 byte stream +- MIDI-CI for property and profile configurations + +UMP is a new container format to hold all MIDI protocol 1.0 and MIDI +2.0 protocol messages. Unlike the former byte stream, it's 32bit +aligned, and each message can be put in a single packet. UMP can send +the events up to 16 "UMP Groups", where each UMP Group contain up to +16 MIDI channels. + +MIDI 2.0 protocol is an extended protocol to achieve the higher +resolution and more controls over the old MIDI 1.0 protocol. + +MIDI-CI is a high-level protocol that can talk with the MIDI device +for the flexible profiles and configurations. It's represented in the +form of special SysEx. + +For Linux implementations, the kernel supports the UMP transport and +the encoding/decoding of MIDI protocols on UMP, while MIDI-CI is +supported in user-space over the standard SysEx. + +As of this writing, only USB MIDI device supports the UMP and Linux +2.0 natively. The UMP support itself is pretty generic, hence it +could be used by other transport layers, although it could be +implemented differently (e.g. as a ALSA sequencer client), too. + +The access to UMP devices are provided in two ways: the access via +rawmidi device and the access via ALSA sequencer API. + +ALSA sequencer API was extended to allow the payload of UMP packets. +It's allowed to connect freely between MIDI 1.0 and MIDI 2.0 sequencer +clients, and the events are converted transparently. + + +Kernel Configuration +==================== + +The following new configs are added for supporting MIDI 2.0: +`CONFIG_SND_UMP`, `CONFIG_SND_UMP_LEGACY_RAWMIDI`, +`CONFIG_SND_SEQ_UMP`, `CONFIG_SND_SEQ_UMP_CLIENT`, and +`CONFIG_SND_USB_AUDIO_MIDI_V2`. The first visible one is +`CONFIG_SND_USB_AUDIO_MIDI_V2`, and when you choose it (to set `=y`), +the core support for UMP (`CONFIG_SND_UMP`) and the sequencer binding +(`CONFIG_SND_SEQ_UMP_CLIENT`) will be automatically selected. + +Additionally, `CONFIG_SND_UMP_LEGACY_RAWMIDI=y` will enable the +support for the legacy raw MIDI device for UMP Endpoints. + + +Rawmidi Device with USB MIDI 2.0 +================================ + +When a device supports MIDI 2.0, the USB-audio driver probes and uses +the MIDI 2.0 interface (that is found always at the altset 1) as +default instead of the MIDI 1.0 interface (at altset 0). You can +switch back to the binding with the old MIDI 1.0 interface by passing +`midi2_enable=0` option to snd-usb-audio driver module, too. + +When the MIDI 2.0 device is probed, the kernel creates a rawmidi +device for each UMP Endpoint of the device. Its device name is +`/dev/snd/umpC*D*` and different from the standard rawmidi device name +`/dev/snd/midiC*D*` for MIDI 1.0, in order to avoid confusing the +legacy applications accessing mistakenly to UMP devices. + +You can read and write UMP packet data directly from/to this UMP +rawmidi device. For example, reading via `hexdump` like below will +show the incoming UMP packets of the card 0 device 0 in the hex +format:: + + % hexdump -C /dev/snd/umpC0D0 + 00000000 01 07 b0 20 00 07 b0 20 64 3c 90 20 64 3c 80 20 |... ... d<. d<. | + +Unlike the MIDI 1.0 byte stream, UMP is a 32bit packet, and the size +for reading or writing the device is also aligned to 32bit (which is 4 +bytes). + +The 32-bit words in the UMP packet payload are always in CPU native +endianness. Transport drivers are responsible to convert UMP words +from / to system endianness to required transport endianness / byte +order. + +When `CONFIG_SND_UMP_LEGACY_RAWMIDI` is set, the driver creates +another standard raw MIDI device additionally as `/dev/snd/midiC*D*`. +This contains 16 substreams, and each substream corresponds to a +(0-based) UMP Group. Legacy applications can access to the specified +group via each substream in MIDI 1.0 byte stream format. With the +ALSA rawmidi API, you can open the arbitrary substream, while just +opening `/dev/snd/midiC*D*` will end up with opening the first +substream. + +Each UMP Endpoint can provide the additional information, constructed +from USB MIDI 2.0 descriptors. And a UMP Endpoint may contain one or +more UMP Blocks, where UMP Block is an abstraction introduced in the +ALSA UMP implementations to represent the associations among UMP +Groups. UMP Block corresponds to Group Terminal Block (GTB) in USB +MIDI 2.0 specifications but provide a few more generic information. +The information of UMP Endpoints and UMP Blocks are found in the proc +file `/proc/asound/card*/midi*`. For example:: + + % cat /proc/asound/card1/midi0 + ProtoZOA MIDI + + Type: UMP + EP Name: ProtoZOA + EP Product ID: ABCD12345678 + UMP Version: 0x0000 + Protocol Caps: 0x00000100 + Protocol: 0x00000100 + Num Blocks: 3 + + Block 0 (ProtoZOA Main) + Direction: bidirection + Active: Yes + Groups: 1-1 + Is MIDI1: No + + Block 1 (ProtoZOA Ext IN) + Direction: output + Active: Yes + Groups: 2-2 + Is MIDI1: Yes (Low Speed) + .... + +Note that `Groups` field shown in the proc file above indicates the +1-based UMP Group numbers (from-to). + +Those additional UMP Endpoint and UMP Block information can be +obtained via the new ioctls `SNDRV_UMP_IOCTL_ENDPOINT_INFO` and +`SNDRV_UMP_IOCTL_BLOCK_INFO`, respectively. + +The rawmidi name and the UMP Endpoint name are usually identical, and +in the case of USB MIDI, it's taken from `iInterface` of the +corresponding USB MIDI interface descriptor. If it's not provided, +it's copied from `iProduct` of the USB device descriptor as a +fallback. + +The Endpoint Product ID is a string field and supposed to be unique. +It's copied from `iSerialNumber` of the device for USB MIDI. + +The protocol capabilities and the actual protocol bits are defined in +`asound.h`. + + +ALSA Sequencer with USB MIDI 2.0 +================================ + +In addition to the rawmidi interfaces, ALSA sequencer interface +supports the new UMP MIDI 2.0 device, too. Now, each ALSA sequencer +client may set its MIDI version (0, 1 or 2) to declare itself being +either the legacy, UMP MIDI 1.0 or UMP MIDI 2.0 device, respectively. +The first, legacy client is the one that sends/receives the old +sequencer event as was. Meanwhile, UMP MIDI 1.0 and 2.0 clients send +and receive in the extended event record for UMP. The MIDI version is +seen in the new `midi_version` field of `snd_seq_client_info`. + +A UMP packet can be sent/received in a sequencer event embedded by +specifying the new event flag bit `SNDRV_SEQ_EVENT_UMP`. When this +flag is set, the event has 16 byte (128 bit) data payload for holding +the UMP packet. Without the `SNDRV_SEQ_EVENT_UMP` bit flag, the event +is treated as a legacy event as it was (with max 12 byte data +payload). + +With `SNDRV_SEQ_EVENT_UMP` flag set, the type field of a UMP sequencer +event is ignored (but it should be set to 0 as default). + +The type of each client can be seen in `/proc/asound/seq/clients`. +For example:: + + % cat /proc/asound/seq/clients + Client info + cur clients : 3 + .... + Client 14 : "Midi Through" [Kernel Legacy] + Port 0 : "Midi Through Port-0" (RWe-) + Client 20 : "ProtoZOA" [Kernel UMP MIDI1] + UMP Endpoint: ProtoZOA + UMP Block 0: ProtoZOA Main [Active] + Groups: 1-1 + UMP Block 1: ProtoZOA Ext IN [Active] + Groups: 2-2 + UMP Block 2: ProtoZOA Ext OUT [Active] + Groups: 3-3 + Port 0 : "MIDI 2.0" (RWeX) [In/Out] + Port 1 : "ProtoZOA Main" (RWeX) [In/Out] + Port 2 : "ProtoZOA Ext IN" (-We-) [Out] + Port 3 : "ProtoZOA Ext OUT" (R-e-) [In] + +Here you can find two types of kernel clients, "Legacy" for client 14, +and "UMP MIDI1" for client 20, which is a USB MIDI 2.0 device. +A USB MIDI 2.0 client gives always the port 0 as "MIDI 2.0" and the +rest ports from 1 for each UMP Group (e.g. port 1 for Group 1). +In this example, the device has three active groups (Main, Ext IN and +Ext OUT), and those are exposed as sequencer ports from 1 to 3. +The "MIDI 2.0" port is for a UMP Endpoint, and its difference from +other UMP Group ports is that UMP Endpoint port sends the events from +the all ports on the device ("catch-all"), while each UMP Group port +sends only the events from the given UMP Group. + +Note that, although each UMP sequencer client usually creates 16 +ports, those ports that don't belong to any UMP Blocks (or belonging +to inactive UMP Blocks) are marked as inactive, and they don't appear +in the proc outputs. In the example above, the sequencer ports from 4 +to 16 are present but not shown there. + +The proc file above shows the UMP Block information, too. The same +entry (but with more detailed information) is found in the rawmidi +proc output. + +When clients are connected between different MIDI versions, the events +are translated automatically depending on the client's version, not +only between the legacy and the UMP MIDI 1.0/2.0 types, but also +between UMP MIDI 1.0 and 2.0 types, too. For example, running +`aseqdump` program on the ProtoZOA Main port in the legacy mode will +give you the output like:: + + % aseqdump -p 20:1 + Waiting for data. Press Ctrl+C to end. + Source Event Ch Data + 20:1 Note on 0, note 60, velocity 100 + 20:1 Note off 0, note 60, velocity 100 + 20:1 Control change 0, controller 11, value 4 + +When you run `aseqdump` in MIDI 2.0 mode, it'll receive the high +precision data like:: + + % aseqdump -u 2 -p 20:1 + Waiting for data. Press Ctrl+C to end. + Source Event Ch Data + 20:1 Note on 0, note 60, velocity 0xc924, attr type = 0, data = 0x0 + 20:1 Note off 0, note 60, velocity 0xc924, attr type = 0, data = 0x0 + 20:1 Control change 0, controller 11, value 0x2000000 + +while the data is automatically converted by ALSA sequencer core. + + +Rawmidi API Extensions +====================== + +* The additional UMP Endpoint information can be obtained via the new + ioctl `SNDRV_UMP_IOCTL_ENDPOINT_INFO`. It contains the associated + card and device numbers, the bit flags, the protocols, the number of + UMP Blocks, the name string of the endpoint, etc. + + The protocols are specified in two field, the protocol capabilities + and the current protocol. Both contain the bit flags specifying the + MIDI protocol version (`SNDRV_UMP_EP_INFO_PROTO_MIDI1` or + `SNDRV_UMP_EP_INFO_PROTO_MIDI2`) in the upper byte and the jitter + reduction timestamp (`SNDRV_UMP_EP_INFO_PROTO_JRTS_TX` and + `SNDRV_UMP_EP_INFO_PROTO_JRTS_RX`) in the lower byte. + + A UMP Endpoint may contain up to 32 UMP Blocks, and the number of + the currently assigned blocks are shown in the Endpoint information. + +* Each UMP Block information can be obtained via another new ioctl + `SNDRV_UMP_IOCTL_BLOCK_INFO`. The block ID number (0-based) has to + be passed for the block to query. The received data contains the + associated the direction of the block, the first associated group ID + (0-based) and the number of groups, the name string of the block, + etc. + + The direction is either `SNDRV_UMP_DIR_INPUT`, + `SNDRV_UMP_DIR_OUTPUT` or `SNDRV_UMP_DIR_BIDIRECTION`. + + +Control API Extensions +====================== + +* The new ioctl `SNDRV_CTL_IOCTL_UMP_NEXT_DEVICE` is introduced for + querying the next UMP rawmidi device, while the existing ioctl + `SNDRV_CTL_IOCTL_RAWMIDI_NEXT_DEVICE` queries only the legacy + rawmidi devices. + + For setting the subdevice (substream number) to be opened, use the + ioctl `SNDRV_CTL_IOCTL_RAWMIDI_PREFER_SUBDEVICE` like the normal + rawmidi. + +* Two new ioctls `SNDRV_CTL_IOCTL_UMP_ENDPOINT_INFO` and + `SNDRV_CTL_IOCTL_UMP_BLOCK_INFO` provide the UMP Endpoint and UMP + Block information of the specified UMP device via ALSA control API + without opening the actual (UMP) rawmidi device. + The `card` field is ignored upon inquiry, always tied with the card + of the control interface. + + +Sequencer API Extensions +======================== + +* `midi_version` field is added to `snd_seq_client_info` to indicate + the current MIDI version (either 0, 1 or 2) of each client. + When `midi_version` is 1 or 2, the alignment of read from a UMP + sequencer client is also changed from the former 28 bytes to 32 + bytes for the extended payload. The alignment size for the write + isn't changed, but each event size may differ depending on the new + bit flag below. + +* `SNDRV_SEQ_EVENT_UMP` flag bit is added for each sequencer event + flags. When this bit flag is set, the sequencer event is extended + to have a larger payload of 16 bytes instead of the legacy 12 + bytes, and the event contains the UMP packet in the payload. + +* The new sequencer port type bit (`SNDRV_SEQ_PORT_TYPE_MIDI_UMP`) + indicates the port being UMP-capable. + +* The sequencer ports have new capability bits to indicate the + inactive ports (`SNDRV_SEQ_PORT_CAP_INACTIVE`) and the UMP Endpoint + port (`SNDRV_SEQ_PORT_CAP_UMP_ENDPOINT`). + +* The event conversion of ALSA sequencer clients can be suppressed the + new filter bit `SNDRV_SEQ_FILTER_NO_CONVERT` set to the client info. + For example, the kernel pass-through client (`snd-seq-dummy`) sets + this flag internally. + +* The port information gained the new field `direction` to indicate + the direction of the port (either `SNDRV_SEQ_PORT_DIR_INPUT`, + `SNDRV_SEQ_PORT_DIR_OUTPUT` or `SNDRV_SEQ_PORT_DIR_BIDIRECTION`). + +* Another additional field for the port information is `ump_group` + which specifies the associated UMP Group Number (1-based). + When it's non-zero, the UMP group field in the UMP packet updated + upon delivery to the specified group (corrected to be 0-based). + Each sequencer port is supposed to set this field if it's a port to + specific to a certain UMP group. + +* Each client may set the additional event filter for UMP Groups in + `group_filter` bitmap. The filter consists of bitmap from 1-based + Group numbers. For example, when the bit 1 is set, messages from + Group 1 (i.e. the very first group) are filtered and not delivered. + The bit 0 is reserved for future use. + +* Two new ioctls are added for UMP-capable clients: + `SNDRV_SEQ_IOCTL_GET_CLIENT_UMP_INFO` and + `SNDRV_SEQ_IOCTL_SET_CLIENT_UMP_INFO`.
