Piano Roll Sequencer
« on: December 25, 2011, 05:35:34 am »
Hey guys, especially the music makers,

here is something I wrote yesterday in Axe 1.0.5b:
A four bar, four octave sequencer for the TI-83+. Just plug in your 2.5 headphones and ready to go.
Using should be quite intuitive but here are the controls:

Arrows - move cursor
2nd - set note
Del - remove note
Trace/Graph - adjust tempo / speed
Y= - play
Window - stop /switch back to  input mode
Clear - quit

Because I don't have an emulator, I only have some stills. But feel free to test it out, there shouldn't be any bugs afaik.
The executable is attached.

Btw... who recognizes those 2 basslines?

You can get the latest version here: http://ourl.ca/14609/274319

Nope.

Definitely not Smoke on the Water. I can tell just by looking at it. It's a fairly nondescript bassline, so I don't know if the exact song will be easily figured out...First thing that came to mind for me was Muse for the first one, but I'm fairly certain that's completely wrong, too.

Still nothing correct, but Muse often does something similar to the first one.

I'll try this soon. I like music tools for calcs. Is it possible to load/save files yet?

Unfortunately, no. But I will add that later, for sure.


And for now, I have added some new features:

- speed now up to 400 Bpm (still very rough)
- transposing (using + and - keys)
- automatic random riff generator! (press MATH): choses one of 5 melodies, generates a rhythm and randomizes the pitch (not just random notes)

Awesome ! Fast (maybe a bit too much), easy to use, powerful... Nice job !  :thumbsup:
The riff machine really adds something, but how about adding customized settings, because here it's totally random. If there were an option to save songs to some Data, it would be perfect.

Saving will be added, for sure. (It still crashes always...)
What do you mean with costomized settings? Something like those in FL? Because that would make the whole thing a lot more difficult and bigger, but maybe later.

Already added (for next version):
- reversing
- cloning

I also will try these things:
- highlighting notes
- copy, cut & paste
- editing only highlighted parts

Yeah, like in FL ! That would be awesome, but I can figure that it's difficult. And why not a longer sequencer ? But maybe the lists are too short for that...

Should be possible, it only uses 32 bytes for 4 bars. I'm only afraid of doing scrolling  :P

Ah... Well, scrolling is not necessary, you could make the user jump to several "boards", each board being a part of the big sequencer.
