New customized firmware modifications
Aargh!!! my LXR just died! Won't power on. I need to take it to the bench. Hopefully it's nothing serious. Anyway I just pushed a new custom firmware at https://github.com/rudeog/LXR. I've done some basic testing, but as I said, my LXR just died so it might be a while before I can fix anything if there are issues.
Anyway here are the changes:
Anyway here are the changes:
- Midi note off fixes. Will send midi off when changing pattern, channel or muting voice
- MTC sync. Will now recognize MIDI MTC quarter frames and start when it receives a 0:0:0 location, and stop when MTC stops
- Program change. Will respond to program change and will change
between the 8 patterns when received via MIDI port. For programs > 7
will use remainder when divided by 8. Also will send on MIDI - Program change. Will send program change 1 to 8 on MIDI when manually changing drum patterns.
Comments
I wonder if it's possible for the bootloader to create a bad flash upload? Strange because it was working fine for a while.
Man these are some great additions!!! I will check the out now.
Thanks!!!
- Midi filtering. You can filter messages from being transmitted or received. Tx is independent of Rx. There are four categories of messages that can be individually configured: Program Change (P), Control Change (C), Realtime start/stop/clock (R), and Note on/off (N). These are set in the global menu under txf and rxf (transmit and receive respectively). Combinations of letters are shown. If a letter is shown, the midi message in that category will be transmitted or received. If set to off, nothing is sent/received, and if set to all everything is sent/received. This has nothing to do with midi routing which works the same way regardless of filter.
- Midi routing (midi soft thru). You can route midi messages from input to output. This is set in the global menu under "mrt". There are 6 possible values: off - no routing, U2M - usb midi is routed to midi out port; M2M - midi received on midi in port is routed to midi out port; A2M - both usb and midi are routed to midi out port; M2U - midi input port is routed to usb output port; M2A - midi received on midi port is routed to both midi output and USB output.
New features:
- Recording will honor midi note setting. This functionality allows midi notes received on channels to be handled in a way that is consistent with how the midi note setting is set for each voice. If a voice's midi note setting is set to "any" and a note is received on the channel designated for that voice, the drum sound is triggered with that note value. If the setting is a specific note, then only that note will cause the drum sound to trigger (with the default note value). This change makes it a lot of fun to sequence and play along with external keyboards. I've been having fun with it.
- For program change and CC, it will still only respond to the channel set for voice 1.
- Global menu is expanded to allow more than 8 settings. Right now there are dummy settings in there after the 8th slot just to test it. This will allow for a lot more switchable customizations.
I'll be doing more testing before I merge to the master of the customized firmware repository. Julian is merging some older stuff, so hopefully we can get this whole thing in sync with some of these new changes in the official firmware soon.
BRAVO!!! exited to try this out
of course, the CCs should respond from any incoming midi channel. Wouldn't this be possible, or is it just still lots of work?
according prog change: is it also possible to change the drumkits now??
thanks for your great work, rudeog!
Also, I'm thinking that it might be more useful to record on whichever drum voice is active (rather than responding only to channel set for that voice). The scenario I'm thinking is that I have a keyboard attached to midi in, and a chain of sound modules on midi out. I might want to quickly record a few sequences from my keyboard for different voices without having to merge midi externally or change channels on the box. So eg, press voice 1, play a sequence, press voice 2, play a sequence, and now voice 1 and 2 are sequencing two other pieces of gear (or playing internal tone generator). If anyone has an opinion let me know. Is it useful to just do it this way or have an option to do it this way as well as the way described in my previous comment?
I might add that this is kind of how the MPC works.
+1 to borfo that's a brillant idea.
I think the extra seqencer tracks topic was discussed before and there were a few votes pro and contra extra sequencer tracks.
I still think it would be awesome to have extra tracks. (possibly with note offs.)
I used the old fw (when there were no note offs at all) to do stuff like trigger/transpose the sequencer or arpeggiator of another synth from the lxr. Its a lot of fun with the retrigger funtion in performance mode, too.
Lots of fun can be had with only lxr+ambika with no other gear.
- Added ability to turn off the "bar counter". This would mean that all patterns will repeat exactly the number of times specified, and then move to their subsequent pattern (as opposed to counting bars from the beginning of the song and switching on multiples of the current "size")
- Added Global midi channel. This channel setting determines 3 things: 1) which channel to listen on for program change messages (and send program change messages) 2) which channel to listen on for CC messages 3) which channel to record notes on to the CURRENT voice.
- Global menu scrolls properly with more than 8 items in it now
Here is a video showing live sequencing from the global midi channel. All sounds are coming from the LXR (the Bass Station is only used to send midi on channel 1). The global channel on the lxr is set to 1, so as I switch voices, it records what I'm playing onto the voice I'm currently on. This is not meant to be musical, just a demo :-):

This is so much more than I ever expected from the LXR!
Thanks for your great work!
- Realtime erase - This is useful, I've found, when recording sequences on a keyboard that are multiple bars (measures) in length. Hold down shift and copy(clear) button. While these are held, the notes on the active voice are erased. You must be in record mode, and the sequencer must be playing. So you could erase a few bad notes as you listen to your sequence, or erase multiple bars as they switch without having to mess around with selecting patterns.
- Recording quantization enhancement - When recording a sequence that spans multiple bars, if you are quantizing, and you hit a note right before the next bar starts (such that the note should quantize to the next bar's first step) it will now do so.
And obviously these are most useful if you are creating multiple bar length patterns (which can be done by setting your repeats to 0, and your next pattern to the next pattern in the chain).
Thank you.
