Launchpad mini MK3 driver

Hi Zynthianers!

I’m working on support for the step sequencer with the Novation Launchpad mini MK3. But, I’ve updated the controller’s firmware (to 2.0), and it does not work with the current driver (I don’t know if the update has any relation at all). It is simply not recognized. The ID of the driver is Launchpad Mini MK3 IN 1, which is, as I understand it, the Launchpad Mini MK3 LPMiniMK3 DAW, as seen with amidi -l. With this ID, the device does not want to change into DAW mode, neither I receive any MIDI message.

If I set it to Launchpad Mini MK3 IN 2, the SysEx to change into DAW mode works (and I see the ‘Session’ button enabled), BUT in that layout (session), I do not receive any MIDI message. If I change to ‘Drums’, ‘Keys’ or ‘User’, I receive MIDI messages as expected (but also the chains). I’ve used the controller with another library that I made, in my PC, and everything works fine.

Could any Launchpad mini MK3 owner test if the current driver (in Oram) works? Thank you!! :slight_smile:

Hi @oscaracena. Zynthian uses a derived name for the device. The kernel driver changed a while ago that broke this and that change became evident when we migrated to the later kernel in Oram. I changed the way the name is derived which works but may differ from what you see in amidi -l. You should be able to see the derived (raw) name in the Zynthian UI by going to the MIDI device’s options (e.g. Admin menu->MIDI Input Devices, bold SELECT on the device) and see what name is shown in the “Rename port” option. This will be prefixed with its type & location, e.g. USB:1.1.1/ and may be truncated due to screen size - so isn’t ideal but may give a clue as to the Zynthian name.

Hi @oscaracena !

I can confirm the driver is working perfectly in last oram with my launchpad mini MK3.
It uses “Launchpad Mini MK3 IN 1” as port device ID for session mode (the one used by the driver). The other port (2) is not used by the driver. FYI, i’ve not updated the firmware.

Thank you @riban and @jofemodo for your time! If your’s works in Oram, then the new firmware is the problem. But, I don’t know why, the SysEx commands and mapping are the same… I’ll keep investigating. Thanks again! :slight_smile:

Are you working with last oram without any mod from your side?
What are the port names you see in the UI log?

Regards,

Yes, I’ve updated just now, and git shows no changes. And with that configuration, even the ‘Session’ button is disabled. Zynthian only receives MIDI as normal. The names are the expected, and also the driver is loaded, but the controller does not work. See this picture:

If I change it to ‘IN 2’, then the ‘Session’ is enabled, but the driver does not receive any ‘midi in’ message.

Could you send UI the logs (debug)?
It seems the session mode is not being enabled. Perhaps this firmware version sucks? Or firmware update was not OK?

Sure, this is the log (I’ve cleaned the snapshot to avoid clutter):

And about the firmware update, it didn’t show any error, and I can enable ‘Session’ mode using the mdevtk library (which uses mido) in my PC, using the interface called Launchpad Mini MK3 LPMiniMK3 DAW.

Perhaps the firmware has crossed device ports. I mean:

  • Launchpad Mini MK3 IN 2 for session MIDI input
  • Launchpad Mini MK3 OUT 1 for session MIDI output

Zynthian assumes (quite reasonably) that you can get the corresponding output port by replacing “IN” by “OUT”. It have worked on all tested devices until now.

Regards,

10

Can I check this in any way?

11

Yes. Tweak it in this function:

zynthian_autoconnect.py → def dev_in_2_dev_out(zmip)

You should add a line to replace “1” by “2” / "2 by “1” and see if it works.

Regards

12

Ok, let me do it.

UPDATE: I’ve made that change, but it happens the same that when I change the dev_ids in the driver: it opens the MIDI interface, and the driver does not receive any MIDI event.

BUT, by error, I started Zynthian without the Launchpad connected, and when I connected it later, it worked flawlessly!! It just does not work when I start Zynthian with the device connected… which increases my curiosity/concern even more… :sweat_smile:

In the autoconnect, names are exactly the same (whether Zynthian starts with/without the Launchpad connected).

13

There is another difference. I’ve changed the dev_in_2_dev_out() function to print the number that returns:

	try:
		name = devices_in[zmip].aliases[0].replace("IN", "OUT")
		for i, port in enumerate(devices_out):
			if port.aliases[0] == name:
				print(f"RETURN: {i}, for {name}")
				return i
	except:
		return None

And, when it works (connecting after boot), it prints:

RETURN: 2, for USB:1.1.4/Launchpad Mini MK3 OUT 1

But, when it does not work (booting with the Launchpad connected), it prints:

RETURN: 0, for USB:1.1.4/Launchpad Mini MK3 OUT 1

May this be related to the problem? This i should always be the same?

UPDATE: I think this is not related. The index changes as the device is added later. These are the contents of devices_out in either case (index port [aliases]):

# when does not work
0 jack.MidiPort('system:midi_playback_1') ['USB:1.1.4/Launchpad Mini MK3 OUT 1', 'Launchpad Mini MK3 1']
1 jack.MidiPort('system:midi_playback_2') ['USB:1.1.4/Launchpad Mini MK3 OUT 2', 'Launchpad Mini MK3 2']
2 jack.MidiPort('ttymidi:MIDI_out') ['ttymidi:MIDI_out', 'DIN-5 MIDI']
3 jack.MidiPort('ZynMaster:midi_in') ['ZynMaster:midi_in', 'CV/Gate']

# when works
0 jack.MidiPort('ttymidi:MIDI_out') ['ttymidi:MIDI_out', 'DIN-5 MIDI']
1 jack.MidiPort('ZynMaster:midi_in') ['ZynMaster:midi_in', 'CV/Gate']
2 jack.MidiPort('system:midi_playback_4') ['USB:1.1.4/Launchpad Mini MK3 OUT 1', 'Launchpad Mini MK3 1']
3 jack.MidiPort('system:midi_playback_5') ['USB:1.1.4/Launchpad Mini MK3 OUT 2', 'Launchpad Mini MK3 2']
14

No. It shouldn’t be relevant. It’s just the index the underlying ALSA driver assign to each device. It can change from boot to boot or depending of the connected devices, etc.

Regards,

15

But it really curious that when connected after booting it gets lower indexes.
I will check this.

16

No, it gets bigger numbers! index = 0 when connect and then boot, index = 2 when boot, and then connect.

17

OK! I understanded the reverse.
Could you connect some other devices to see what happens?

18

Interesting… When I connect the APC Key25, and reboot, it works perfectly! These are the device definitions:

0 jack.MidiPort('system:midi_playback_1') ['USB:1.1.3/APC Key 25 mk2 OUT 1', 'APC Key 25 mk2 1']
1 jack.MidiPort('system:midi_playback_2') ['USB:1.1.3/APC Key 25 mk2 OUT 2', 'APC Key 25 mk2 2']
2 jack.MidiPort('system:midi_playback_3') ['USB:1.1.4/Launchpad Mini MK3 OUT 1', 'Launchpad Mini MK3 1']
3 jack.MidiPort('system:midi_playback_4') ['USB:1.1.4/Launchpad Mini MK3 OUT 2', 'Launchpad Mini MK3 2']
4 jack.MidiPort('ttymidi:MIDI_out') ['ttymidi:MIDI_out', 'DIN-5 MIDI']
5 jack.MidiPort('ZynMaster:midi_in') ['ZynMaster:midi_in', 'CV/Gate']

The index returned in this case is 2. If I disconnect, and connect again after boot, it still works. It has no sense at all! :joy:

19

Can you post the same listing but for when it isn’t working?

20

Yes, you have it here (it only has the Launchpad, as connecting the APC works always):

UPDATE: If I connect only the Launchpad, then boot, and the connect the APC, it has the following mapping (in this setting, the APC works, but the Launchpad NOT):

0 jack.MidiPort('system:midi_playback_6') ['USB:1.1.4/Launchpad Mini MK3 OUT 1', 'Launchpad Mini MK3 1']
1 jack.MidiPort('system:midi_playback_7') ['USB:1.1.4/Launchpad Mini MK3 OUT 2', 'Launchpad Mini MK3 2']
2 jack.MidiPort('ttymidi:MIDI_out') ['ttymidi:MIDI_out', 'DIN-5 MIDI']
3 jack.MidiPort('ZynMaster:midi_in') ['ZynMaster:midi_in', 'CV/Gate']
4 jack.MidiPort('system:midi_playback_4') ['USB:1.1.3/APC Key 25 mk2 OUT 1', 'APC Key 25 mk2 1']
5 jack.MidiPort('system:midi_playback_5') ['USB:1.1.3/APC Key 25 mk2 OUT 2', 'APC Key 25 mk2 2']
