Can't seem to start server

[konsumer]

Not sure what the issue is. I am on Pop!OS 20.10 (similar to ubuntu 20.10)

I have my portaudio routed through Jack, and generally either sort of audio works fine, in other apps. I tried with both runtimes and it quits.

Here is jack:

This one stays open, but nothing connects to it.

[konsumer]

I killed all fas processes, then restarted the jack-based server and it stayed open and added itself to jack, but still not sure how to get sound output.

You may have started the audio server by running the AppImage directly so the server was already started but staying in background. This a known issue (maybe it should be specified on the homepage ?), as of yet i don't know how a terminal can be spawned when running the AppImage directly so the server must be started in a terminal to get any feedback.

The routing look fine, did you tried to slice the canvas (right click on the canvas then click on [+] icon and unpause) ?

Note : just pushed a small update fixing post release issues with FM, this can be found on the homepage

You may have started the audio server by running the AppImage directly so the server was already started but staying in background.

I think you are right. The jack server seems to reliably start now, and I can connect it to stuff in graph.

The routing look fine, did you tried to slice the canvas (right click on the canvas then click on [+] icon and unpause) ?

I did. It's all very new to me, so I may be some other really basic "getting started" kind of step, but I tried a few of the examples, and hit the pause button to start transport, and it doesn't seem to output any sound. Here is an example I am connected to, right now.

Seems like it's working, as I get this in console:

Connection successfully established from localhost (127.0.0.1).

I just don't hear any sound. Is MIDI mandatory?

[konsumer]

With a MIDI keyboard connected (and enabled), and patch set to "additive midi" example, I do get visual output when I hit keys, just no audio.

[grz0zrg]

The canvas data must be captured by slicing the canvas, try to right click on the canvas (where visuals are shown) and click on the appearing [+] icon, this should add a vertical bar which will capture the data. MIDI is not mandatory.

[konsumer]

That was the missing piece! I hear sounds with most of the examples, now. Thanks!

I made a quick youtube video of my first run, to help others: https://youtu.be/PfsjM_f9NfQ

I dunno if it's useful for anyone else, but feel free to use it, if you like.

I'm going to close the issue. Thanks for your help!
