Topic: Pianoteq Debian

Hi. I have tried Pianoteq on my Macbook. Fantastic instrument. I have lots of real instruments here. No pianos though but in my opinion most virtual instruments fail. This one doesn't. Very expressive to play.

The problem is that usually I use Linux. My Linux system is quite old but a good system so I've kept it running. It's a PIV Hyperthreading 3.0 GHz. It's Debian Squeeze with LXDE desktop and Liquorix kernel. Much the same as AVLinux but I don't run many apps so have my own very streamlined set up rather than use AVLinux. Mostly Ardour, Rosegarden and Yoshimi. My sound interface is a Layla 3G. Everything works fine. However, all I get with Pianoteq is a segmentation fault if I try to start it. I have tried on other computers with the same Debian set up and same error.

I would most definitely buy this software if I could have it working on Linux. It doesn't matter so much about my current hardware but I want to know I can use Pianoteq on Debian.

Re: Pianoteq Debian

I have tried Pianoteq on four Linux systems now and three different computers. One system was Ubuntu 10.04. Onboard sound, Echo Layla and Echo Audiofire sound interfaces tried. Always segmentation error.

I've never had a problem either. I'm using it on the current Ubuntu LTS with a vanilla kernel, just the standard ALSA interface, on an AMD dual core 2.1 Ghz in 32bit mode. It just works.

I had no problems with 64bit, or with a real-time kernel, but the gains weren't sufficient to justify the added complexity. Same with Jack, it works, but why bother?  KISS!

It also works fine on a recent Puppy Linux on a USB stick with a 2Ghz Celeron laptop with a smoked hard drive and no battery that I use for casual gigging. Definitely lower sound quality, but good enough.

I would guess the problem lies with the customized kernel and/or a failure to follow the instructions in the Linux readme.

Re: Pianoteq Debian

Re: Pianoteq Debian

Hi. Thanks for replies. Yes, the problem is odd and it looks like something I am doing is wrong yet what can that be? It happens on all my systems.

I make the assumption that Pianoteq should open even if just on a standard Linux system with no tweaks, say a straightforward clean Ubuntu. Whether it actually works or not is another matter but should it open?

I have tried opening Pianoteq from my home folder and also from user bin folder. I have tried right clicking and open and tried starting from command.

My Debian system is really where I want to use Pianoteq. It's the same set up as AVLinux except more streamlined. For example when I start the system, the Ardour session dialog starts up ready to begin an Ardour project. That's all I see. It's almost dedicated to Ardour but anything else works fine. It is set up in the standard way that you'd set up a system for audio. The things mentioned in the text file with Pianoteq have already been done. I am running a realtime kernel with Jack. Other systems I have don't use the Liquorix kernel and I still get this problem so that doesn't seem to anything to do with it.

Re: Pianoteq Debian

Went back to Ubuntu again to double check. Same problem. Segmentation fault. This happens on every single system. I even downloaded the Pianoteq file again just to make sure there wasn't any problem with that.

Although I have tried various ways to start Pianoteq I am making the assumption it just requires double clicking on the Pianoteq file in say your home folder and it should start even if you don't have a system well set up to make it work correctly with Jack etc.

Check the properties of the executable file and make sure that you are the owner and that the executable bit is set.

Re: Pianoteq Debian

I've already checked the properties of the file. It's all correct.

I'm getting hold of the latest AVLinux. I'll check that and see what the score is.

Re: Pianoteq Debian

OK, ran further tests.

Pianoteq 3.6.6 fails on my systems (PIVs and a Centrino). Pianoteq 3.6.5 works fine. Don't know what the issue is. I used both versions exactly the same way.

Re: Pianoteq Debian

Went through this methodically. Even downloaded Pianoteq again. Treated each version exactly the same.

3.6.5 works perfectly on all my computers. 3.6.6 fails totally on all of them.

Re: Pianoteq Debian

Pianoteq 3.6.6 Linux demo is now fixed. It did have a fault and Modartt have supplied a new file.

Re: Pianoteq Debian

Hey efflux,
can you please tell how did you fixed the problems? Also, would like to hear from you about the best kernel to test the demo 3.6.6. I have tried it with ubuntu studio 11.04 and got an incredible amount of xruns and  crackles, which makes it very unpleasant to use. jack messages are disturbing too; it's like there are issues between jack and pianoteq. Hope you can post your settings. Please take a look at my thread here:

thanks.
