How to bounce to disk in Synfire 2?

Posted

I try to bounce some arrangement to disk as an audio file. I found the bounce to disk icon right of the playback controls at the top. When pressing it and playing the arrangement, then a *.wav file is indeed created, but the resulting wav file only recorded silence.

What am I missing here? Do I perhaps need to select something to be actually recorded? Being required, e.g., to select a time span to record would indeed make sense, but I cannot find how I could do that.

The doc says this feature "requires all instruments to use the same Audio Engine". The instruments of my arrangement seemingly use Engine1:06, Engine1:07, .... (None uses Engine1:01 to Engine1:05). Does this count as using the same engine? If not, how would I change the engines used? I tried clicking on the engine of an instrument in the Arrangement Rack to see whether this can be changed, but it says that "This rack module can not currently relocate", and offers a number of reasons why that are difficult to me to comprehend.

Hi,Tanders!
Sorry I have  have to disturb you at this question, short after release of Synfire 2 I post a question about to making changes to one already made phrase in factory mode and you give me an answer and now I can’t remember what it was. I remember that it was possible but not how? Perhaps you can repeat it!

The Engine needs to be on the same computer and all instruments need to be hosted on that Engine (no DAW Drones, VEP servers or external MIDI). I'm using this feature all the time for demo tracks. No idea why it wouldn't work.

I am indeed only using a single computer and only standard Synfire tracks (no drones etc.). Do these engines I listed look OK for you? Thanks!

I handle the recorder very carefully as it will act like a tape recorder and will record silence if you're paused between project or moving between other projects I believe, cant remember too much because my procedure hasnt changed and I just do it automatically. That is open synfire, load your project, make sure no other window or project is open, press the tape icon, press play, when recording is finished: press stop, press recorder icon to stop recording, close all synfire windows (if open). Never stop playback, rewind or open another project while running. If you for example stop or rewind it will record silence and the jumps between song sections. Once the .wav file appears, you can resume normal operation. Some of these steps are not necessary and I skip them now because I have internalized it and can't exactly remember what I do. But I remember it took some experimentation to get it working correctly. Then I run a powershell script which calls ffmpeg or lame to back up the whole directory into an MP3 folder with the date, or just rename the .wav file If i'm working on one file and want to do a variation.

Does this count as using the same engine? 

Yes. It's all Engine1

Win 10 should be fine.

Forgot to mention also, if there is a file with the same name as the project I think it will just append to it, so delete if you want to start with a fresh "tape"

I meanwhile was able to bounce the file. It seems that after the file was created and the playback stopped, one has to wait for quite some time until the file is actually filled with the recording. Or perhaps there is some issue with Audacity, which I used for opening the file.

Yeah I remember having have to wait too, but whatever i'm doing, I get it pretty quick these days. I just ran a quick test and after closing synfire got the file after less than 20 seconds, depends on the length of the file perhaps as I just recorded a short 5 second section.
