Alsa guitar effects?

hi, thanks

you may try some alsa-plugin or -bridge that let's you insert some LADSPA plugins (caps* and guitarix are some pretty nice ones here), whatever, but quite frankly, it's a dang PITA to make it right, let alone the time you'll get to even work first time, whether decently at all: you'll certainly need to deal with lots of esoteric command line hacks, editing some illusive configuration files, know asoundrc syntax by heart and what not... :)

but you should try making that zubuntu of yours (is that an alternate spell to Xubuntu or is it something I never heard of, til now?) to work with JACK2 at least...

you must know that a guitar player wants--rather demands--the lowest latency turnaround for live performance, and that, I must tell, you can only find to work reliably with JACK, or otherwise on a fine tuned system that would run JACK quite stable in the first place anyway...

so why ask for less when you can have more? :)
iow. what exactly is stopping you there?

cheers
