Oops, could be there's still some issues with the code I wrote. I
really *will* try and find some time to look at this.

Everything other than ctrl-select and ctrlp-select should be okay.

OK. I tried it again on a fresh install of Fedora Core 7 with Ecasound
The program still dies in the original place at the "ctrl-select"

Hi Stuart,

I upgraded to v2.4.6.1 and now I get a completely different error:

(ecasoundc_sa) Error='read() error', cmd='c-select pink1' last_error=''
cmd_cnt=50 last_cnt=49.

* Message from libecasoundc:
* Connection to the processing engine was lost. Check that ecasound
* is correctly installed. Also make sure that ecasound is either
* in some directory listed in PATH, or the environment variable
* 'ECASOUND' contains the path to a working ecasound executable.

Any ideas what might be wrong?

Thanks so much!

Hi Sara,

This is almost certainly due to bugs I put in the ctrl-select and
ctrlp-select functions when I first wrote that code :(

I sent a fix to Kai that made it into 2.4.5 so an upgrade to that
version or later should fix it.

Sorry about that.

Hi All,

I'm using ecasound in interactive mode from a c program via
I have a chainsetup with a ladspa multiband eq that is attached to some
controllers. I have pasted some code below. This works and sounds
fine but when I try to select a controller with ctrl-select to change
its value the program always seems to crash.

eci_command("c-add pink1");
eci_command("ai-add null");
eci_command("ao-add jack_generic,pink1");
eci_command("cop-add -el:tap_pinknoise");

//pink noise eq
eci_command("cop-add -el:mbeq");

eci_command("ctrl-add -kos:6,-70,30,1,0.5");
eci_command("ctrl-add -kos:7,-70,30,.12,0");
//jack connect and ecasound start stuff here

All fine up to now, ecasound connects and starts without problem,
program continues...

Later in the program when I try to change controller values with these

eci_command("c-select pink1");
eci_command("ctrl-select 6"); //select controller band 6

Ecasound and jack die at the "ctrl-select' command.
I've printed out "ctrl-status" and it looks like the controllers are
present and running normally.
Anyone know why this would be happening?

Ecasound version is: ecasound v2.4.4

Thanks so much.
