ALSA: seq: ump: Skip useless ports for static blocks

2024-07-27T09:36:19+00:00

commit 3bfd7c0ba184de99e9f5083b29e5308f30767265 upstream. When the UMP Endpoint is configured with static blocks, the block configuration will never change, hence the unused ports will be unchanged as well. Creating sequencer ports for those unused ports is simply useless, and it might be rather confusing for users. The idea behind the inactive ports was for allowing connections from/to ports that can become usable later, but this will never happen for inactive groups in static blocks. Let's change the sequencer UMP binding to skip those unused ports when the UMP EP is with static blocks.

ALSA: seq: Fix missing MSB in MIDI2 SPP conversion

2024-07-05T07:37:55+00:00

[ Upstream commit 9d65ab6050d25f17c13f4195aa8e160c6ac638f6 ] The conversion of SPP to MIDI2 UMP called a wrong function, and the secondary argument wasn't taken. As a result, MSB of SPP was always zero. Fix to call the right function.

ALSA: seq: Fix missing channel at encoding RPN/NRPN MIDI2 messages

2024-07-05T07:37:54+00:00

[ Upstream commit c5ab94ea280a9b4108723eecf0a636e22a5bb137 ] The conversion from the legacy event to MIDI2 UMP for RPN and NRPN missed the setup of the channel number, resulting in always the channel 0. Fix it.

ALSA: seq: Fix incorrect UMP type for system messages

2024-06-16T11:51:15+00:00

commit edb32776196afa393c074d6a2733e3a69e66b299 upstream. When converting a legacy system message to a UMP packet, it forgot to modify the UMP type field but keeping the default type (either type 2 or 4). Correct to the right type for system messages.

ALSA: seq: ump: Fix swapped song position pointer data

[ Upstream commit 310fa3ec2859f1c094e6e9b5d2e1ca51738c409a ] At converting between the legacy event and UMP, the parameters for MIDI Song Position Pointer are incorrectly stored. It should have been LSB -> MSB order while it stored in MSB -> LSB order. This patch corrects the ordering.

ALSA: seq: Don't clear bank selection at event -> UMP MIDI2 conversion

2024-06-12T09:39:52+00:00

[ Upstream commit a200df7deb3186cd7b55abb77ab96dfefb8a4f09 ] The current code to convert from a legacy sequencer event to UMP MIDI2 clears the bank selection at each time the program change is submitted. This is confusing and may lead to incorrect bank values tranmitted to the destination in the end. Drop the line to clear the bank info and keep the provided values.

ALSA: seq: Fix missing bank setup between MIDI1/MIDI2 UMP conversion

2024-06-12T09:39:52+00:00

[ Upstream commit 8a42886cae307663f3f999846926bd6e64392000 ] When a UMP packet is converted between MIDI1 and MIDI2 protocols, the bank selection may be lost. The conversion from MIDI1 to MIDI2 needs the encoding of the bank into UMP_MSG_STATUS_PROGRAM bits, while the conversion from MIDI2 to MIDI1 needs the extraction from that instead. This patch implements the missing bank selection mechanism in those conversions.

2024-04-19T10:07:14+00:00

The conversion from MIDI2 to MIDI1 UMP messages had a leftover artifact (superfluous bit shift), and this resulted in the bogus type check, leading to empty outputs. Let's fix it.
