Lemur BLM

blingy · April 8, 2014, 4:01am

I am trying to figure out how to use the Lemur BLM template.

First: do I need to have a wireless router to use it without a computer? Ideally I would like to connect the ipad directly to the hub that is powering the midibox! This only sort of works, in that the USB ports on the Midibox are visible to the ipad and I can start and stop and somewhat edit sequences. However some of the buttons do not work as expected. I suspect it might have to do with the OSC part of the setup, which I do not understand.

I made a little video showing the best I’ve gotten it. Notice that the eighth step in the sequence never gets highlighted, it’s also unselectable and the 16th step highlights the 9th one! I’m confused. In this case I’m connecting the ipad directly to the USB hub, but the same thing happens if I use a USB to midi adapter and set the BLM port to the MIDI port.

Thank you !!!

Well I’m trying to get it working with a V4, but had issues with my v4l as well…It could be a bug in Lemur, they just did an update recently and I’m pretty sure I had this working before. On the other hand, my v4 crashes totally when I select the OSC outs as the BLM scalar in the midi settings! I’ll do more testing with my V4L tonight and see if I can get those settings saved on mine.

It will recognize Lemur over USB or MIDI but it’s not working quite right as shown in the video above. If anyone else can check the BLM_scalar setting in 4.079, it’s under MIDI->Misc. Move the encoder up above the usb and midi settings and let me know if it stops responding. TK’s got me digging into the code and I must say that it is as beautiful on the inside as it is on the outside!

Well nothing jumped out at me looking over the BLM code so I tried downgrading Lemur. iOS apps appear to be nearly impossible to downgrade if you don’t have a backup handy. This is exactly why I stopped using software to write music. I’m about to throw this stupid ipad out the window. Talk about non-free software.

Interesting, this is working perfect for me with the Camera Connection Kit. Barely any setup at all when I plug the sequencer directly into the ipad. Select a port in the lemur setup and assign a port to the blm in sequencer and its working. Was working fine for me over wifi with lemur daemon as well but I havent tried that in while. Ill check it when i have more time. I’m using an ipad air with the lastes ios and lemur.

Thanks lukas, that is good information. Are you running 4.079? What are you plugging it directly into, the midi port?

Is it this Lemur template you’re using? http://www.ucapps.de/midibox_blm/MIDIbox_BLM16x16+X_v1_002.zip

Did you get a chance to try setting the BLM_SCALAR setting under midi settings?

One more question, have you tried it with a channel set up as a drum channel? That’s what I’m doing here…

Thanks for the compliment!

Hopefully I will get some time to doublecheck the most recent Lemur version at my side this weekend.

Best Regards, Thorsten.

OK I’ve been able to do more testing with another LPC17 core. For sure if I set BLM_SCALAR_Port to 64-67 (The OSC ports as I understand it) neither a firmware flashed with a SEQ or SEQ v4L will boot. I got those numbers by setting the default port and then looking at MIDI_DefaultPort, so I could be off with that assumption and if they are nothing at all, I could see that causing problems.

Then I did some more testing of the Lemur BLM. Basically it seems to work fine with the V4L firmware. It also seems to mostly work with seq v4, with the exception of drum mode, which of course is the killer app of the BLM for me. I’m not sure how deeply I ever used drum mode before so I can’t say for sure that this was working for me before, but I am still trying to get my hands on a copy of Lemur 4 to test whether or not the issue was introduced by their update.

More test results, works perfectly in the BLM emulation. So Lemur does seem to be the problem.

T.K · April 12, 2014, 7:39pm

It’s a bug in Lemur!

“<variable> |= <value>” isn’t working anymore.

I added a workaround (“<variable> = <variable> | <value>”) which solves the issue - patterns are displayed correctly again!

-> MIDIbox_BLM16x16+X_v1_003.zip for Lemur

Best Regards, Thorsten.

Of course it works flawlessly now. Thanks TK. I think that bitwise or might be undocumented anyway…didn’t end up live sequencing any drums but there is always next time…

Is it working on your V4l? I installed the new lemur file and created a MBSEQ_GC.V4 file with the OSC and BLM_SCALAR settings - the settings stuck on reboot, but still not seeing any button “led feedback” in lemur. I didn’t have time to do any troubleshooting yet - I’ll dig into it more deeply when I have time. But it’d be good to get confirmation that it’s working on someone’s V4L if that’s possible.

T.K · April 13, 2014, 9:02pm

I tested it on a V4L yesterday.

Please try the latest version: http://www.ucapps.de/mios32/midibox_seq_v4l_082_pre3.zip

Best Regards, Thorsten.

Great… I’ll take a closer look this weekend and see if I can get it working. Thanks.

Out of curiosity, does anyone have the Lemur BLM working over ethernet? It’s working fine on USB for me now, but I still can’t get it to work over Ethernet.

T.K · June 7, 2014, 7:53pm

The required configuration is explained in the MBSEQ manual: http://www.ucapps.de/midibox_seq_manual_blm.html

search for “osc_remote”

Did you try the same?

Best Regards, Thorsten.

borfo · June 7, 2014, 8:30pm

Yeah, I did that - specifically:

set osc_remote 3 192.168.11.102
set osc_local_port 3 8000
set osc_remote_port 3 8000
set osc_mode 3 1
set blm_port OSC3
store

USB works without issues (although I have to hardcode the connection into the MBSEQ_GC.V4 file on the SD card), but ethernet/OSC doesn’t seem to work. The V4’s ethernet connection is working fine.

t’s not too much of an issue since I can use USB, but I thought I’d check if anyone else has the ethernet connection working before I try troubleshooting it anymore.

T.K · June 8, 2014, 4:47pm

It still works at my side, but I noticed a problem with the “store” function - it doesn’t store the network setup.

Could this be the problem at your side? (check the current configuration with the “network” command)

The fix will be available with the next release.

Meanwhile you could enter the configuration directly into the MBSEQ_GC.V4 file:

BLM_SCALAR_Port 66

and

OSC_RemoteIp 2 192.168.11.102
OSC_RemotePort 2 8000
OSC_LocalPort 2 8000
OSC_TransferMode 2 1

(note that in this file the connection numbers are counted from 0)

After the changes, enter “reset” to reload the configuration.

Best Regards, Thorsten.

Cool - Store hasn’t been working for me. I wasn’t sure whether that was a bug or whether it was something on my end. I’ll try again once the next release comes out, and I’ll also try entering the settings directly into the GC.V4 file.

Thanks.

How are the BLM_SCALAR_Port numbers calculated? Is that documented anywhere?
