Dear all,
I discover this project : http://hoxtonowl.com
and I am currently taking some of their patches (open source) and implement to the LXR .
For the moment , I did the compressor that works really fine..

I will continue with the reverb and next the delay.. I cross the finger .. I hope it will work !

bye!

Reverb algorithms:

I have an "issue when compiling":

warning: implicit declaration of function 'memset' [-Wimplicit-function-declaration]
           memset(reverb_buffer, 0, sizeof(reverb_buffer));
           ^
./src/DSPAudio/distortion.c:303:11: warning: incompatible implicit declaration of built-in function 'memset' [enabled by default]

the code is:          
...
memset(reverb_buffer, 0, sizeof(reverb_buffer));
...

what is the issue, why the compiler is shouting !!!
:-)

I found the issue, I added at the top of my program:

#include <string.h> /* memset */

#include <unistd.h> /* close */


issue solved.

Does that mean that you can turn LXR into FX box just by using another SD card with different firmware? I guess that merging some stuff into LXR FW is not possible due to memory restriction, right?

Hello,
you could turn the sonic LXR machine into a FX box, but then how do you insert the input lines?
so you could create your own synth (for sure) plus adding FX... but not realtime treatment from an external audio source :-(

if you have one of the very early boards you have an additional ADC on board (if there are no free spaces on the mainboard)

on the other boards you can add an ADC if you can solder SMD.

That's what all the green jumpers are for.

In the beginning I had plans to maybe re-use the board for other projects so I added an ADC, but probably any new project needing an ADC will use another board so I discarded that Idea later on.

hello,

can t wait to see how this is working!!

cheers

I have looked more into details to this project and especially to the code of certain of their plug in. I adapted the simple compressor they made, as well as a "bitcrusher". thanks to this migration, I improved my comprehension about the LXR code and the way you could implement new effects. The road is still long but I should release a new LXR firmware: LWR-OWL with 6 nice audio effects and midi effects.

I recorded this afternnon 20 minutes using the LXR and playing with the new effects I implemented.. enjoy the listening ;-)

80% of the drum sounds and bass (yes!) are coming from the LXR using the new LXR-OWL effects :-)
I added a moog midi murf ...

Enjoy the listening ;-) and give me your advices!

LXR-OWL is coming soon!!! get ready!
