I am looking for a way to use the LAPSPA/LV2 plugins without the heavy weight hosts (like GuitarX or MODEP)
... There is mod-host specifically for LV2 plugins. IIRC it can be controlled through some kind of network protocol (telnet, you can script that) or it has a command shell and can use MIDI learn. I have used mod-ost with scripts of its own command run from the interactive shell. A tool that can use both LADSPA and LV2 (the latter to a limited degree) is Ecasound. You can run a whole setup from the commandline. Since Ecasound has a lot of options, here is one example line, adding the CAPS Plate 2x2 by its ID, since I never remembered the label: ecasound -f:16,2,48000 \ -i jack_multi,system:capture_1,system:capture_2 \ -o jack_multi,system:playback_1,system:playback_2 \ -eli:1795,0.9,0.5,0.3,0.2 This will start Ecasound with 16bit, 2 channels at a samplerate of 48000Hz . Thye input and output is specified with the most flexible JACK type I/O, specifying each poort you want to connect to: this will require the ports being there when Ecasound starts. The eli (Effect LADSPA ID) specifies the unique ID (1795) of the plate reverb and then gives values for its four parameters. Ecasound also has a shell - and even a high level API for C, C++ and Python to control parameters and other setup detais in realtime. It can also take some MIDI control. Ecasound limitations: each chain (input -> effects -> output will have the same number of channels right through, so no way to install a sidechain effect and use it properly. With LV2 plugins you'll have to see what works. AFAIK: no instruments, no channel mismatch (see above) and nothing with too manby purely GUI controls (i.e. not available as ports). mod-host will run instruments and things with different numbers of input and output channels. Though it can't access features which are only available through the GUI. In practise that means: no file loading (IR files, samples, synth banks,...). It's very useful foor running normal effects and synths with hardcoded basics. You can store settings as a script. HTH.
