AU DLS Synth 1

    Mar 25 2006 | 3:44 pm
    Hi There,
    I'm a very recent beginner (I'm currently on Tutorial 20 of the manual) and I've suddenly come across a problem with Max outputting midi data to the Quicktime synth. This has only recently happened as I've been working through the tutorials using the Quciktime synth fine. Now Max can send midi to other virtual synths (such as Simplesynth) (and there is no problem get midi data in) but I no longer here midi notes sent to the Quicktime synth.
    I've checked the list archives, and read an old thread referring to the AUgraph object but to no avail. The strange thing is I've checked the synth using other applications (such as Live or midi files) and it appears to still work fine?
    I'm running 4.5.7 after thinking upgrading would solve this.
    Any ideas?
    Thanks in advance.

      Hi Chris,
      No prob here, Max/MSP 4.5.7 - QT 7.0.4 - OSX 4.5
      Just test your setup with the MIDItester patcher from the Extras menu, it should work fine.
      Bye, P.G.

      I can confirm this problem. "AU DLS Synth 1" has not worked with noteout for a few weeks on my machine. I was playing around with soundfonts using the fluidsynth~ object around that same time.
      I was using 4.5.5, so I downloaded and installed the updated augraph object... still broken. I just updated to 4.5.7 and still no luck with noteout. Any more information on how to correctly reset the driver bank is appreciated.
      ; #SM driver loadbank 0 "AU DLS Synth 1"
      This doesn't work and a cursory look in the documentation didn't turn up any more info.
      Thanks, Danny

      Works really fine for me, through noteout or through midiformat- >midiout. Have you tried to load some soundfonts with max messages, something like that:
      - load a soundfont called Synth1.sf2 (change for any other sf, double-quote if the filename contains space chars), located in your root library: file://localhost/Library/Audio/Sounds/Banks/
      ; #SM driver loadbank Synth1.sf2 "AU DLS Synth 1"
      - set back the default QuickTime DLS:
      ; #SM driver loadbank 0 "AU DLS Synth 1"
      Otherwise, quit Max, delete some preferences files, or the the whole "Max 4 Preferences Folder".
      HTH, Philippe

      I recently had some kind of problems too... I tried to send messages to ;max, but it didn't help. I also though that the volume level of the DLS Synth was set to 0 (you can change it with the MIDI volume controller). My only solution was to throw away some preference file (midi@augraph.txt maybe) and restart Max.

      Ok, it is working now. In my case it turned out to be a simple matter of having the i/o vector size set too high. Dropping it from 2048 to 1024 or lower solved the problem.
      Thanks to all for your responses, Danny

      Got the it working again! Deleted the preferences in Library/Application Support/Cycling74/Mididrivers restarted no effect. Changed i/o vector size as suggested above (thanks Danny) works fine - great back to the tutorials :-)

      Has anyone ever on a Mac successfully created a new DLS outport and loaded a new soundfont ? I'd like to hear from you. I keep getting the following error: � error: augraph: bank set error -2147450879.

      Great Chris, glad it worked.
      In the interest of being complete I will note that Patrick was referring to the preferences in "~/Library/Preferences/Max 4 Preferences Folder/ ". Specifically, deleting my "CoreAudio@Built-in Aud.txt" file reset the i/o vector size to an acceptable default level. I am not sure that deleting /Library/Application Support/Cycling74/Mididrivers is a good idea.
      Cheers, -Danny

      Thanks Danny to take care of my posts! Indeed, I was of course referring to the users's preference folder. But I'm quite sure now that it was the midi@augraph.txt preference file that I deleted.

      I did, successfully! And still works fine: OSX 4.5 - Max/MSP 4.5.7
      Would you post a patcher to check if it works here?
      Bye, Philippe

      yeah, deleting the Mididrivers folder isn't a good idea as it deletes the gui that configures the midi preferences! I deleted it started the program then put it back when I realised what I had done. The vector size was the winner.
