Valhalla Tracker v0.2.3

Hello, all
I'd like to announce first public release of a new live sequencer for Gnome. It is a tracker (I know, I know). I needed something to put between a MIDI controller and Carla. Think of it as a minimalistic MIDI repeater with some added value. The user interface is written in Python, the library that talks to JACK is written in C. Being a one-person project, the code-base can get a bit convoluted (as I were able to just come up with stuff as I went along). Nevertheless, I think it might be of useful to some of you, if only to experiment with "unheard of" time signatures.
Enjoy!

Thanks for the release!
quick test : I can confirm it installs to ~/.local and can be started.
JACK midi ports work and I get output.
I've seen the keyboard shortcut list, but without knowing what to expect from the program I fear there is a lot one needs to figure out by trial and error.
How about a quickstart tutorial video?

Thank you for trying it out. Yes, it definitely needs a tutorial. Hope Trent won't mind:

Keep in mind this is alpha software, I keep finding 2-3 bugs in it each day.
Once again thank you for your interest.

I had already discovered it a while ago, it's very nice! Does it support changing time signatures during the song?
I made a package for it on openSUSE but one problem I had is that it uses a very recent version of Python 3 (the := operator). I think one idea to make a package work across most distros without creating headaches to packagers is to target the lowest version available at the very least on the mainstream non-rolling distros (Ubuntu LTS, Debian, openSUSE Leap, Fedora). You can find this info on repology.org usually. For now I just patched the := away as it's very easy to refactor but I wanted to give my two cents as a packager

Tried on Debian SID.
After installing the dependencies and "./setup.py install --user", launching vht i get this:
Code: Select all

You might get away with a warning. If you comment out line 28 in vht/console.py, it won't check for version. Your vte is older than it expects, but I probably just pasted that check from stack overflow. Do the setup again.
Next!
Yes, you can change bpm in the middle of the song. It's a showcase of weird design choices. If you manage to highlight and click on that little yellow arc on top of the timeline, just under the buttons, bpm will light up in status bar. That's your bpm for node zero (which you cant move, because it's The Zero Node). If you hold ctrl and hover your mouse somewhere under it, you'll see a yellow dot. Click and a new node will show up. You can set your new bpm. Double click and it will be interpolated from the last node. Don't freak out when things start stretching.
And thank you so much for packaging this. It's the main thing I hope will "sort itself out by the community". Will now try to actually make music in it for a few days. That should straighten it out a bit.
All we need now is an Amiga version, which with sequencer engine in C can't be so far away. Then port it to Megadrive! No, I'm just winding myself up again...

Thank you, now it's starting. I had to install libvte-2.91-dev also.
I was looking exactly for something like this. Very cool project.

Thank you. Means I was not the only one
Started adding some documentation to the wiki to explain the less obvious stuff.
