Postby ullotar; Sun Jul 30, 2017 2:08 pm Filter frequency tracking save/load issue

Hi,

There appears to be a problem with saving/loading of the filter frequency tracking parameter.

To reproduce:
- Change the filter frequency tracking value to something non-default
- Save the instrument by using the Write function in the Bank window
- Load the instrument by clicking on the instrument in the Bank window
- Now the filter frequency tracking value of the loaded instrument is the default value, not the non-default value which was saved previously.

My version of zynaddsubfx: 3.0.2, provided by the kxstudio repos.
I am using the standalone version, with the legacy UI, on Linux (ubuntu studio 16.04 with kxstudio repos).

It affects all synth engines (AdSynth, SubSynth, PADSynth).

Loading of old instruments (ie. instruments created with 2.5.x and 2.4.x i think) works fine.

Can you confirm that the filter frequency/q/gain are loaded correctly?

A recent (now fixed) bug created an issue when loading tracking/frequency/q/gain when loading within a VST/LV2 host, but I don't think that bug should also affect the standalone.

Once this bug is confirmed fixed and a few smaller issues are fixed with the windows VST there should be a 3.0.3 bugfix release.

The bug is confirmed to exist in the current git version. I may have time to fix it tonight.

Thanks!

I built from source and it works nicely.

Is there an easy way of figuring out which build dependencies to use?

I ended up (through some trial and error) with these packages
- libfftw3-dev
- libjack-jackd2-dev
- liblo-dev
- libmxml-dev
- zlib1g-dev (one some systems only zlib-dev?)
- libasound2-dev
- libxpm-dev
- libfltk1.3-dev (also needed are some recomended deps: libglu1-mesa-dev, libgl1-mesa-dev
without these deps, cmake reports that FLTK cannot be found)
- fluid

And also had to install build tools
- build-essential
- cmake
- cmake-curses-gui
