I've worked a bit with bintracker. Very pleasant and quite intuitive to use. It reminds me somehow of 1tracker.
Text file format rocks! (I'll tell later why)
I've changed the colors in the settings.ini, now it looks so nice.
I've set the keyboard to FR. Now I have something odd. I won't open an issue because it's maybe a quick fix.
Alt+1...+5 is working fine for changing the octave. Alt+6 is decreasing the length of the song instead of choosing octave 6! Alt+8 is increasing the octave, as expected. Alt+7 does nothing. In english keyboard mode (I've changed my keyboard with setxkbmap us), it's similar, except that alt+6 is working as expected.
So as I said, I saved my file first, then made a new version with more data in it. Then I removed some rows with the alt+6 command. I didn't want to undo, so I just saved my file under a new name, and compared it with the first version with a diff tool to retried the infos from the deleted rows.
Really, text source rules! (something I like too in 1tracker)
For the deletion of some notes, I found it strange that "del" is shifting all values in the column up. Probably some trackers are doing this as well, but I think it's more commun to just delete the value with "del", and shift values up with "backspace" (like in 1tracker or milkytracker). But we can get used to it. Also the problem is sometimes the keyboard responds odd and I get two inputs instead of one. So instead of deleting 1 note I wanted to remove, and stay on the same place, it will delete the note and the next one not supposed to be removed.
For the selection of special commands, I didn't understand how to select the value until I read the manual. Well maybe I'm a bit dumb, but when I began to type, I got a selection list. I tried to select one item with the arrows, but it didn't work. I tried to click, it didn't work. I tried to type the first letter of the command, hoping it would cycle through all the item (on/off), didn't work either. Then I discovered we have to enter the first letters. It's that simple. But maybe using arrows or cycling with only one letter would make it simple for newcomers, just an idea (maybe using mouse it too overkill). After, I noticed for some commands, like up/down, just typing the first letter works so it's good when you're used to the tool
Now I'm working more on my tune!
