Re: [ecasound] ladspa-Plugin "Gate 1410" not working in multichannel setup

Hi Oliver,

Cool that you can use ecasound for recording and rough
mixing your band.

I can see that the line after the TL chain looks like it was
improperly wrapped.

If you are interested in having a bit more control, you
may look into Nama, a multitrack recorder using
Ecasound as the back end.

The usual way of working with Nama is create a track and set
the input channel(s) for each instrument, which are then
recorded as separate .wav files. For listening, each track
gets a volume and pan control, and mono tracks are
copied to stereo.

I think Nama is available on ubuntu (which will install the
dependencies) however you may need to do build from github
to get the latest.

regards,

Joel
