DLS synth to 8 channels?

I would say that you need to instantiate it four times. As far as I know, it only provides two-channel output.

but the three extra instances would also go to channels 1 and 2. What i'm lacking is control over which channels the synth goes to.

I'm don't have a Digidesign setup on this computer I am at now, but if I use Soundflower 16 channel as the driver, and in AULab build a setup with four stereo outputs using soundflower channels 1-8, then each instance of Apple DLS Synth gives me a choice of Stereo Mix, Output 1, Output 2, Output 3, or Output 4. What is strange is that if I choose one of the other outputs (other than stereo mix) from the menu on the plugin inspector, the inspector goes blank. Nevertheless, I can assign each instance to a separate output in the mixer window--each instance has its own channel strip which can be assigned to any combination of outputs, busses, etc.

What application are you using it in?

I'm doing everything from within Max, choosing the DLS synth from the popup menu on the noteout object. I'm not familiar with AULab.

Okay, I see. I not sure how you address the output of a built-in DLS synth from inside Max anyway. In 4.5, multiple DLSs are supported (see WhatsNewInMaxMSP45, pp. 11-12) as devices that MIDI can be sent to, but if there's a way to do all of this from inside Max/MSP, someone should please let me know. In fact, I don't even see where they can be determined to be mono or stereo from inside Max. My guess is that, with the lack of any other intervention, they use whatever output device the Default Output is set to in AudioMIDI Setup.

My approach to that would be first to create an aggregate device driver combining you Digidesign CoreAudio driver and the Soundflower 16 channel driver. You can put the Digidesign driver first in the list, so they are output numbers 1 through 8, and make the Soundflower channels 9 through 27. Next, startup your AU host and choose your new aggregate driver as the driver for that application. Instantiate your four DLS synths you need in a separate program like AULab (if you have developer tools installed, it is in /Developer/Applications/Audio/) or other such AU hosting app. Assign the outputs of the first to channels 9-10, the second to 11-12, etc. You can work with the DLS more thoroughly from here. In Max, set the audio driver to your new aggregate driver, and use an adc~ 9 10 11 12 13 14 15 16 to get your audio into max, and it can eventually leave through a dac~ 1 2 3 4 5 6 7 8.

Since 4.5, you can even create more virtual MIDI ports to control each synth totally individually if you like. Just type in a message box [; #SM createoutport mynewport1 coremidi; #SM createoutport mynewport2 coremidi]

If there is an easier way to do this, someone please let me know.

Thanks.

I'm not really sure if it's correct to say that the DLS synth is 'within Max' - probably not. It appears automatically in the popup menu for noteout. I did download an object called Argos fluidsynth, which apparently enables soundfonts to be loaded and controlled. But where exactly is the DLS soundfont? I don't find any files named anything like it.

I'm not sure i see your point in creating an aggregate driver, which is something i doubt digidesign would permit, as it's decidedly hoggish. I just want to be able to assign to the 8 channels that i already have. It's already sending to channels 1 and 2 of digidesign, so it should be able to send to the others.

sorry to jump in late. did anybody mention the fluidsynth~ external?
it can host soundfont-synths like dls and outputs directly into msp.

hope this helps

thanks. I've seen mention of the fluidsynth~ external and tried to download it, but downloading requires that i install something called CVS. It's considerably more difficult than it should be, but perhaps I should make work of it.

or if you or someone could post the fluidsynth~ external or send it to me, that would be splendid.
