We just pushed a new IR Convolver to the Store.
This is the one that allows you to load big files.
It has both mono and stereo variants.
By default it uses multiple threads for background processing, easing up on CPU load but introducing 1 cycle of latency.
Plugin originally coded by our dear @x42 (using the zita-convolver and fftw behind the scenes)
The source code for it is at GitHub - x42/zconvo.lv2: Zero Config Convolver for those that want to check those kinda things.
Now, from my tests the Duo can load quite a good range of IRs but has trouble with the bigger files.
Dwarf and Duo X were able to handle all files I could throw at it
Found 1 little issue, reported to the author but we can fix it if he is busy with other things.
When loading a pedalboard sometimes the IR file is not loaded, instead keeping the default/initial one.
The plugin refuses to load an IR file while it is still loading a previous one, which in our case is the default/initial one.
Something to fix soon (and surely before pushing to stable), but it does not prevent testing for now.
Updated the plugin just now, still in beta but now has a modgui and fixed the issue with quick loading of IR files (“next” file is put on hold in a queue for later loading if one is already being loaded)
The modgui is not final, opinions / suggestions are welcome.
Another update, after talking with @x42 he merged the changes needed for a queue-type system (in a different way, but same idea), so that is part of upstream/official project now
For MOD some little tweaks were still needed, but from my testing it works well after those.
Still to do is optimizations/tweaking taking into consideration the MOD units.
On desktop the plugin could run at any arbitrary buffer size, but on MOD only 128 and 256 frames are allowed for now. And we know in advance how many cores the target system will have, so we can tweak the plugin a bit to behave better under these known conditions.
Mod DuoX user here, the moment I drop the plugin (both mono & stereo versions) on my pedalboard, the ui freaks out. Reloading does not fix it, only changing the pedalboard through the device again and then reloading the browser.
I can confirm this @christosku.
I even listen to the hardware bypass relays of the DuoX acting when it disconnects. It feels like as if something was rebooting.
ping on this @falkTX
Plugin has been updated again, now with tweaks for MOD units in specific.
Hopefully no side effects, give it a try and let us know how it works!
Thanks
Yet another update.
Some more tweaking to the background thread processing.
Duo and Dwarf should be able to load bigger files, tested with a 7 second one.
And while the Duo can load and run such big files, you cannot really make much more than that when those are active.
The only thing I can see missing is the ability to assign which Impulse Response is being used to a hardware control, knob, midi or whatever so you can change IR without being hooked up to a computer.
