I wonder if any of you have managed to have two c-sound synths running at the same time in max?

When trying out the help file for c-sound, I cannot figure out how to have two c-sound patches at the same time in one max patch - I am also looking at the c-sound code for the help file ... perhaps it needs to be defined there, somehow? Does anyone have a working example?

I just copied the fof example into the main help patch tweaked parameters andit worked.

Two seperate csound objects with seperate instruments seems to work fine

Thanks for your reply, I did what you suggested and yes, it is possible, but what if I want two of the same c-sound instrument in one patch? What in the attached c-sound-code examples that are now identical (and in the corresponding max patch (see below) do I need to change? I looked closely at the c-sound code, but it was not clear to me what to change (something about the midichannels and the corresponding "pattrforward IN" in max ... ?)

I needed to get the .csd names to match first, there were minor diffs from the csound message - must be identical . . this was not much off an issue . . .

Next I made sure that the FM parameters and ADSR were set on the RH copy - they get lost during cut and paste. And without them set the orc wont sound . . .

With this done it plays but still through LH patch still, so I looked at pattrforward - these names want to be different on either side otherwise they send to the same place. ie the LH side in this case.

So rename them all to patrrforward IN1f or LH & IN2 on RH sides, then set the scripting name of the tiny little [t l] trigger object next to the csound~ objs to IN1 (LH) and IN2 (RH) and add a 1 & 2 to the 'IN' label next to them so you remember . . .

Oh and you will have to do something with the preset objects to sort them out - the copied one is still talking to the original patch and they are both set to capture all objects - set them up how you want them . . . .

Could send an edited patch but I think you can sort it out easy enough . .

Thank you for the instruction. I tried to do what you mentoned, but I still have problems finding the right places in the c-code to do this:

"Next I made sure that the FM parameters and ADSR were set on the RH copy - they get lost during cut and paste. And without them set the orc wont sound . . ."

See the max patch posted below, how I changed it according to your instructions, and the two attached c-sound codes ...

Oops, I made a mistake, I still needed to add the right pattrforward names in multiple places in the max patch, however, it still doesn't work:

Give us a few minutes and I'll post a patch . .

Sorry - The main issue was that the [t l] trigger object 'scripting name' needed to be set in the Inspector for that object ( not in the object parameters). Added a few more preset connections to - you want to get the ADSR and Output parameters as well

This works now for me . . .


Thanks for your help. I see. I copy pasted your patch and instrument two works, while instrument one now doesn't work. I wonder if this is because my c-sound code files are identical ... what do I need to change in the c-sound code? (see attached). I think that I don't really understand your instruction:

PS. Yes, I know that I need to dive into the csound manual and do all the tutorials. I just thought that it wouldn't be a big deal to build two of the same kind of c-sound instrument in one patch ...

It should work - Should not need to change anything in .csd

The instructions referred to when you first copiy/pasted the RH part of the patch - it lost values. I simply had to give it the necessary ADSR, FM parameters and Volume.

Make sure ALL user interactions are at sensible values . .

Any error messages in max window? Maybe a typo somewhere . . .

Added a few more things to the presets and gave the presets seperate scripting names via the Inspector.

Try the stuff in the attached zip file - patch plus .csd's . . . Put them all in Max path obviously.

Thanks for the zip file - on my laptop I still only get sound from the second one. It must be something (some dsp settings ... ?) or outside max that bugs me. I tried the files you just sent and my cpu peaks at 70% then after a while it falls to 30%.

I think I need someone here locally to look at how my laptop is set to run sound ... if it works on your computer, it should work on mine too.

Are you using the onscreen keyboards? or midiin?

If it is the midiin check that its port is assigned properly . ..

InValues , ADSR , Outvalues and Volume faders all should be set too . . . Volumes should be up quite a way.

If you are on a Mac we may be able to set things up so I can share your screen and work it out for you, maybe Skype ?

But it should work - both csounds are sending to the same dac~ so it should not be that because you can here one.

. You should see both orcs being processed in the Max window - there should mentions of both scores and a waveform for each. If this is not happening - hit the 'start' or bang to actually start the csound engine, but then we would have to work out why it is not doing it automatically via the loadmessage.

have a bit more of a play and get back to us - maybe send us the post from the Max window from when you start the patch . . . .
