if i recall correctly this is a known issue, i reported it as well as a few others.
thanks for the info.
I’m not sure if it has been addressed in other threads yet but I was wondering about panning in MLR. It would be awesome to have panning controls for the four tracks. I am wanting to use the stereo outs on Norns in order to spatialize my sounds but it doesn’t seem like any scripts really address that (other than being able to load in stereo files).
another thing I didn’t see any info about was a method for assigning the two inputs to specific tracks in MLR.
any thoughts or insights would be appreciated.
sorry, like brian i’ve been occupied with lots of non-norns related things in the past weeks.
but in the background we’ve made some infrastructure changes to the norns SC system allowing (among other things) voices in this engine to be processed on separate CPU cores. so we have much more total processing available and i can go ahead and revert some of the corner-cutting changes, meaning better interpolation and more audio-rate params for MLR (better sync, smoother fades.)
adding panning and filtering per-voice in the engine is definitely something i want as well. and it is quite simple. how to control such addditional params from MLR interface is another question that i probably won’t worry about.
(actually the engine does support panning already, now that i think about it - just the mlr script doesn’t provide any controls for it (yet)).
this thing with the channel assignments is pretty baffling. it’s not intentional, and i’m 99% sure that it’s not something the engine itself is doing. seems as though MLR script is somehow setting up the engine to sample from the master outputs (after monitor bussing? really i don’t get it) instead of directly from the inputs. will investigate.
anyways, various engine-level improvements are coming soon.
To clear the audio buffer I record silence into it - there’s no quick button combo that does this. Also note you can record different audio into different loop points of the same channel.
Don’t forget you can load up prerecorded wav files also. Its easier to line everything up and prepare in say Ableton first. Use the main menu on norms to load in samples and 3rd page in MLR to assign your samples.
The fun is with the pattern button recorders - they work on both pages, not just the second page.
I wanted to share some finding from using MLR in a live situation. Errors that I have found. Ive read the thread and cant see then mentioned already, so was wondering if anyone could shed any light on them. connected to Grid in all instances.
Sometimes certain record channels don’t work - this is from turning Norns on. All visual queues work as should but channel 2 won’t record (mostly 2 in my case, but once 2&4).
On startup (5% of the time I would say) all lights start as normal but nothing functions. If you push a light button it goes off. Have to restart.
Sometimes record is all bitcrushed - I cant pinpoint this at all but happens about 10% of the time
any feedback or potential fixes would be welcome. Im planning to use Norns live in a performance so having this ironed out would be better for my health.
They are aware of the 2 and 4 channel not-recording bug.
Regarding bit crushed audio, forgive me if you are aware of this, but if you have the speed of that channel set to something other than standard speed, the recording will be at a different speed (can sound bit crushed if you record while set to higher speed then set playback to standard speed).
Also, one of the developers mentioned they are working to clean up the audio so it isn’t as bitcrushed…but I like it and think it would be cool if they gave us a clean and more bit crushed option in the parameters!
hoping that possibly in the future that something can be implemented so when the user presses record and stop that mlr would recognize the tempo based on the length on the first recording in a project. Kind of the same way that pickup machines work on the Octatrack. This would make live looping a lot easier without having to maybe pre-load a percussion track to keep the time for the rest of the available tracks. Im not sure if this would be possible or not. I need to get up to speed in learning lua
Love this idea.
I also think a taptempo function would Be equally useful!
There really does need a better way to work with the tempo and loops, maybe a metronome at te least? All ideas for now
Cheers, yeah thanks I was aware. what I have is a little different and intermittent. all good.
thanks for the info.
Am I missing something, where is the 3rd page?
You talking about on the
- Rec level / Overdub
- Volume / Speed mod
pages? thats all i have.
@yelsnit Sounds like the 3rd page being referrred to here is the Clip page, accessed on the grid itself — it’s the third grid key from the left on the top row.
Little MLR quick start pdf here, in case you hadn’t seen it:
great, got it.
Only thing I dont get now is how to get files on Norns.
Ive attached a USB stick (and tried a HD) but the files don’t load.
Keep in mind that - at least for now - files can’t be read directly off an external drive — you have to copy them to Norns’ internal storage in order for them to be accessible.
Have you checked the Norns docs, and in particular the System / Sync section there? Good info on file management/backup. Once you get your Norns backed up to your USB drive, you can then load samples to the
/tape folder on your computer, and then sync those Norns for use in the various scripts.
Apologies if this is all old news to you — just figured I’d cover the bases
yeah Ill do that now, wasn’ aware of that. Ill get stuck into the docs and leave you alone! Cheers for the link and the help in general.
Recording in to a quantized enabled channel (ch 1) with Grid and midi sync (CV.OCD attached) caused a crash that froze Norns. Had to reboot from bottom for a fix.
After rebooting everything I record plays back distorted/broken in mlr.
to my understanding there are some outstanding issues with midi sync at the moment that have been addressed and are being worked on
thank you all for spotting some issues. i plan to prioritize an mlr update with the next batch of updates.
- midi and grid connected cause grid crashes, midi sync unreliable
- input 1/3 2/4 bug
- sound quality improvement with speed mod (or tempo mapping)
- panning per track (very easy, probable)
- buffer clear
- start/stop buffer length set method
Do you intend to add MIDI clock IN too?
Also, would there ever be the possibility of handling stereo audio per track, either incoming audio or a loaded sample? Or is it an engine limitation?
