Even 4 extra midi patterns would be very useful. Or a single pattern that allowed 4 note polyphony (3 extra notes to the main note as +/- semitone offsets)
rudeog, great to hear you are working on a merge. looking forward to it.
do you think the hardware could handle extra midi/cv tracks besides the standard set?
Could you explain the Load/Save Performance multiple slots and PRF files a bit more?
Also, do you need to save a named Pattern first, before you can save a Performance that will recall a pattern?i.e. the Performance save just links to a named saved …
Just want to show you my LXR. I built it within two nights without any problems at all.It sounds great. And with the ability to load your own samples it's even greater! I have a lot of fun with it!And it's in good company with my two Shruthi's (SMR4…
possibly your dead LED is soldered the wrong way around? if not you could still desolder it and a working one and resolder them back, swapping their locations, to check if the LED itself is a dud.
mazamo, there should be a firmware.bin on your SD card and you need to hold down the lone encoder to the side of the lcd as you switch the lxr on to get the update starting.
https://www.dropbox.com/s/m7fq66m0e69tjit/FIRMWARE.BIN- you need a folder on the sd card named "samples"
- put some 16-bit mono wavefiles in there (not more than 490kB!)
- on the load screen there is a new option "load samples"
- confirm with 'ok',…
Took off LCD again, trimmed and resoldered everything beneath it even though they all looked ok. Resoldered the pins, re-attached the LCD.
1st try .... it works. What a relief. detaching and reattaching the LCD is not fun. Must have been some bad so…
With no front panel on, I can only boot while pressing the bottom edge of the lcd panel downwards, sync will only work when i release the pressure on the lcd. However then my lcd text is corrupted when i try some menus.
if i keep the pressure on th…
my solution is not to put the top left little black screw to hard. as soon as i screw it to the max sync is gone. when i have it a bit loose it works... thats how i am having fun with my lxr. and i can tell you, i am having a lot of fun http://www.…
Also the midi sync works when the audio sockets aren't plugged in.
Also when I change to the firmware posted above.
Took off the front panel, and with audio plugged in, midi sync now works.
It seems to be related to pressure on the LCD is causing…
gone up to 0.23 and now it sometimes sync and sometimes not. the audio ports dont affect it anymore, so maybe the oversoldering helped on that.
anyhow, directly after powering up my hardware (i have one main switch for all) it doesnt work directly.…
just tested with midiox; octatrack sends PCs when changing patterns/banks in audio track mode, so if LXR patterns could respond to those would be great.
Just looking at a few messages seems like the OT, starting with A01 sends PCs 0, 1,2,3 etc as y…
I don't think this is implemented (tried sending some prog change message to it and it didn't change the active pattern) - I agree it would be very useful.
@fcd72 - and soon it will be a cook and a chauffeur... so adding a couple thousand samples per pattern certainly seems doable.
Even just the current 512k in-memory sample pool being available globally to choose from per step would be powerful stuff…
@mokomoDo you want a sample for every step and voice? Thats can be as much as 122 Samples.... you are awary that initially the LXR was meant as a Synthesizer, not a Sampler ? :ar!
@FCD yes it is a bit sacrilegious to be going down the sample-seque…
6144bytes instead of 512...
With that amount of memory available, would it be possible to allow the [STEP] [nte] on each synth track to select different .wavs loaded to memory?
eg C1 would be a kick, C#1 would be kick2, D1 would be a snare etc and …
the kHz should not matter.
It just means the pitch range of the sample will be off compared to 44.1kHz samples.
You are free to use 22.05kHz samples to save some space and pitch them twice as fast
Trimmed the same set of samples down to remove mor…
here's a sox batch converter script for a windows bat file to drop .wavs onto (to ensure they are 16bit mono 44.1k with silence trimmed off the end) ... you'll need the sox.exe folder in your path:
cd %~dp0mkdir LXRconvertedFOR %%A IN (%*) DO sox %%…
Successfully loaded 13 samples of various lengths (12k to 47k in size)
some samples are particularly 'clicky' perhaps due to zero crossings? Changing their Coa parameter can avoid this at various settings but not all. It isn't a gradual thing, singl…
inverted background might be difficult, involving creating custom characters on the LCD which might have a limitation in the number of characters available.
maybe blinking text might be easier; set the text to alternate from blank (or 3 * ASCII cod…
ah, thought it might be that.So I can just do
editDisplayBuffer[0][(activeParameter%4)*4] -= 32;editDisplayBuffer[1][(activeParameter%4)*4] -= 32;editDisplayBuffer[2][(activeParameter%4)*4] -= 32;
To change all 3 characters?
Glad it worked for you. The easiest type of customization to make would be to modify strings that are displayed. You could do this without any great in depth knowledge of the code, and your results would be visible. Also, you don't have to worry abo…
Followed your steps and now have my LXR running on your build with no problems.The code looks well-commented too which is great.
Wish I knew a lot more C and could get involved in experimenting!
If you come up with some interesting tweaks, could yo…
dot, on your second point, you are aware of the Parameter Fetch option?
e.g. you are on Voice 1, with the first pot on OSC (dialled to about 9 O'Clock) setting Coarse to 17.Then you change to Voice 2 where Coarse is already at 65. With Parameter Fet…
so I guess that means we'd need to build a custom firmware on our desktop, pulling in the samples there, and then run the bootloader for it on the LXR... still would be great.
on the other hand I have at least 500kb flash memory left.
Maybe an option for small user sample kits would be feasable for the future...
no promises here, just an idea so far...
That would be PHENOMENAL ... perhaps a designated folder on the SD c…
