It appears that the scale parameter in the midi chord utility only offers the whole chromatic gamut of keys within the same major scale. Is there a way to choose a different scale or mode? Harmonic minor, dorian, locrian and so forth.
I noticed the same limitation in the scale utility itself.
Yep. These tools are simple to use but quite limited. It would be nice to have something more powerful.
The source code of all these utilities is free, so a brave programmer could manage the task of improving them. The obvious next step is opening a feature request in our tracking issue 
Regards!
There is a different chord plugin that I wrote because of the limitation of the one we had. I am sure it is in Zynthian.
You are right, but it’s not enabled by default or it’s missed in Oram. I will check.
Thanks
