qtractor lost sound

Post by sebigbos »

Hi,

I started to use qtractor yesterday. I use it to play midi files. I only had to choose an sf2 in "instruments" and my imported midi files played.

Today there is no sound output any more. I already searched for hours, un- and re-installed qtractor, but nothing. There are no error messages and jack is running.

Has anybody an idea where to look?

perhaps can anybody give me an answer to some general questions.

When I have a bus master midi, which is configurated by default, without installing a synth plugin in "output plugins" and when choose a sounfont in "instruments", will qtractor then play the soundfont using an internal synth plugin? I think I it was configured like this in the beginning and this worked.

I get an output sound now, when I route "Calf fluidsynth" in "Busses/Master Midi out/output plugins" and assign a soundfont there. But this only works for a specific *.qtr file, not for default.

When I try to assign a synth plugin in the mixer window, right clicking the field under master out, I can choose a soundfont there but I don get an output and if I look wether the soundfont is still there, it isn' t. Perhaps could this be a problem with file rights, for example of some config files of qtractor?

Hopefully waiting for professional help here, guys!

nope. qtractor has no internal synth whatsoever; the .sf2 that you import in the View > Instruments... dialog is just for easy selecting banks and programs by name on the track properties dialog and menus; implies that there's a SF2 synth in or out to the MIDI track--it is your responsibility to provide one, inserted as a plug-in on the track or output bus, or connected to an external standalone (eg. qsynth).

hth.
cheers

o.k., thanks.

so I had success implementing a-fluidsynth, the fluidsynth-child provided by ardour. The "normal" fluidsynth works, but doesn't take the instrument patches defined in my midi files. Is there a possibility to do this as default to all files, a fixed routiing?

dunno about ardour's a-fluidsynth though, whether it accepts MIDI bank_select and/or program_change channel messages; but rest assured that fluidsynth and qsynth standalone do, as in compliance to the SF2 spec.

I don' t use the qsynth-standalone but the fluidsynth DSSI plugin and this only plays piano. Don't know why but doesn't matter, the ardour fluidsynth works like a charme.

thanks for help.

Check the track's setup. Qtractor sends program change commands when the track is configured with them. Also be sure to load the correct soundfont.
