rncbc announces the second coming of the Vee One prototypes - synthv1 and samplv1 for Linux (Jack & LV2)

rncbc has announced that a couple of "proto-alpha thingies" have been released in the wild. After being informally announced through the Linux Audio and Musician venues, they come in both pure JACK stand-alone and LV2 plug-in formats.

synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

samplv1 is (yet another) old-school all-digital polyphonic sampler synthesizer with stereo fx.

Hey. I tried to compile but got the error:

configure: WARNING: *** LV2 header files not found.
configure: error: *** JACK and LV2 build options disabled.

Im not well-versed in compiling but would like to try the synth...

you need do install jack(-audio-connection-kit) and/or lv2 (>= 1.0.0) packages from your distro, especially the development ones ie. usually named after libjack-dev and lv2-dev resp.

nb. i'm follwing the debian/ubuntu nomenclature as is the most common around; on my call i use opensuse for ages and there the packages are slightly different, but the clue is that a -devel suffix is used instead of just -dev.

hi, edencane

perhaps, you need the latest lv2 (>= 1.0.0) which replaces older and deprecated lv2core package.

anyway, you may wish building just the jack stand-alone client (synthv1_jack) instead of the lv2 plugin. try this:


make jack

sudo make install_jack

this should end with /usr/local/bin/synthv1_jack being installed by default and ready to run.

otoh, you could also grab one of binary packages from my OBS (opensuse build service) repositories:


see if any fits your bill; there are .rpm's and .deb's for both opensuse (known to be compatible with fedora) and ubuntu resp. and regular 32bit (i586.rpm, i386.deb) and 64bit (x86_64.rpm, amd64.deb)... just dig in for the proper stuff, download and install as usual :)

Thanks. Ill give that a try next Monday and let you know how I go.

Hi. I did that and got the synth running. Now I have to figure out how to get some sound out of it, I guess Ill have to connect a MIDI keyboard...


Best Regards.
