Aquileo | Cycles in module connections cause instant crash

2013-04-06T09:09:32Z

Any time you create a cycle in the module graph, AMS crashes with a segmentation fault. For example, using the demo file example_basic.ams, connect the output of the VCA (ID 4) to the linear FM input of the VCO (ID 5) and the application will crash immediately. Note that if you first disconnect the PCM Out (ID 1) this crash does not occur. There may be technical reasons why such cycles can't be allowed, but I hope a future release of the app can provide an error message rather than crashing.

Aquileo | Function blocks don't work.

2012-02-18T23:05:23Z

The function blocks (1->1, 1->2, and 1->4) have two problems:

1) the "track line" needs to be reinitialized by the user before it even draws correctly (mode pulldown to "reset", then click on the line).

2) Even when it draws correctly, the output is always zero, no matter what the input.

I looked at the code but I don't have a fix for either.

Aquileo | bad window function in FFT Vocoder

2012-02-16T17:41:54Z

For some incomprehensible-to-me reason, the Hann window (one of the FFT window functions) fails - and locks up AMS.

For now, I'll just disable that wndow function.

Patch attached.

Aquileo | ams-2.0.1 fails to link because of missing -ldl

2012-01-20T23:19:22Z

First, LDADD should be used to pass libraries, not LDFLAGS and then...
src/ladspadialog.cpp is using functions like dlsym, dlerror, and dlopen but src/Makefile.am doesn't have any references to -ldl so we end up with errors like:

attached patch solves the issues

Aquileo | QMidiRoute: Output-Note not set correctly after loading .qmr

2010-07-13T11:36:22Z

In QMidiRoute, if a .qmr file is loaded in which a saved Map used "Fixed" in the Output-Note dropdown list, the map behaves as though "Offset" was chosen, even though "Fixed" is displayed in the box.
If "Fixed" is reselected, the map then behaves as expected again.

Eg:
I make a Map that takes any note and outputs a fixed note 4.
I save the settings to test.qmr
Later, I load test.qmr. The Map shows "Fixed" in the dropdown list, but the output is whatever note played plus 4.
I reselect "Fixed" from the list. The output is now always note 4 as expected.
