Hello.
I write hoping that some nice LADs might enlighten me ?
I've been feeling a recent itch to write a simple step-sequencer,
which outputs MIDI messages to the ALSA seq ; it is intended to drive
a drum machine. My ideal app is provided with a graphical UI which
includes HUGE buttons (to give you an idea, the GUI in FL Studio comes
to mind).
It may seem silly at this point, but I could not find an existing app
which exactly suits me.
But anyway, I think it will be a piece of fun trying to write
something myself...
I shamefully admit being no good at C/C++ programming, but I could
write some GUI code in Python/Java, which would communicate with the
sequencer engine, over OSC for example.
Regarding said sequencing engine, I have found 3 possibilities so far :
- Chuck
http://chuck.cs.princeton.edu/
- Midishare (can be driven in Java, Lisp, ...) *provided that I can
get it to compile on my Gentoo box ...
http://midishare.sourceforge.net/
- Milk (Python MIDI engine for ALSA)
http://www.quitte.de/milk.html:
The former two seem slightly more complete ; in particular, I very
much liked Breakage, which uses Chuck :
http://www.blackholeprojector.com/
(Actually, this app would have been a very good fit, but it is
Windows/Mac only :-o)
I'll finally make my point : which framework would - in your
experience - be the most practical to use ? Or the most interesting to
learn ?
Many thanks for your attention.
NB : I am aware that Hydrogen is one fine app ;-), and probably a step
sequencer can be written as a Pd patch in seconds, but that is not
what I am after at the moment ; I insist on the user interacting with
big, Playschool-like BLOCKS :-)

Actually, if you look at the FAQ on the Breakage site it claims to run
on Linux as well. It's Java so I guess if you download the "ChucK-less"
version from their site and acquire ChucK for yourself that should do it.

Oh, you are right : there are 3 downloads : Mac, Windows and ChucK-less.
I have downloaded the ChucK-less version, and it launches ChucK and
Jack alright; i only had to create symlink ln -s /usr/bin/chuck
./chuck

The Java part is free but not open-source, though.
Thanks for making me notice ; I have some material to play around with :-)
Is there activity around midishare ? The forum does not seem to have
been too busy recently.

There are Python bindings for the Dino library. It's not released yet

You might take a look at gneutronica, the result of me
scratching a similar itch.
http://gneutronica.sourceforge.net
It's surely not exactly what you're after, but
if you had in mind C, gnome based UI, alsa sequencer
interface (though, maybe a somewhat naive implementation,
as I was just learning all that stuff as I went) it might
be something worth looking at as an example, and there
might even be some code you could grab from it. It doesn't
talk to JACK... someday I might get around to figurnig out
how to do that, but it's not in there now.
I shamefully admit being no good at C/C++ programming,

Oh, well... maybe gneutronica's not what you're looking for then.

Thanks for suggesting Gneutronica :-) It provides useful answers to
some of my needs.
If I had to make one main adjustment to my personal preferences, it
would be in the way that the pattern is visually rendered : while your
way of indicating note velocity (according to its vertical position on
a grid) makes it efficient and precise to set, I find it is not easy
to visualize the whole rhythm pattern at a glance. Not so easy as
colouring the block in a progressive shade of black&white would make
it, IMHO.
Well, maybe one gets used to it after working on the editor ... I will
install Gneutronica and make a more insightful feedback :-)

Hm, that's an idea I hadn't thought of. More difficult to program...
Also, though it's mostly a step sequencer, if you uncheck the "snap to
grid"
box, then the timing is freeform, and the gridlines become just
visual guides, so there really is no "block" to color, but maybe the
background color of each row could be graded along the x-axis
according to the velocity of notes in the vicinity... sounds a
little processor intensive to accomplish though. Or maybe just
pre-generated bitmaps could be pasted, or single pixel high
gradient lines duplicated vertically... Exactly how to do that
in gnome is not something I know off the top of my head.
Well, lately my music programming has been to do with a voice
editor for my yamaha motif rack (kind of a pain to program
that thing) but even that has been put on the back burner for
awhile, so I doubt I'll be tweaking the graphics on gneutronica
anytime soon.
If you (or anyone) wanted to experiment, the code that draws
each row in that grid is in gneutronica.c, in the function
called canvas_event(). The for loop towards the bottom is
where it draws each note. I'm thinking it wouldn't be too
hard to add a section that draws a series of vertical lines
of diminishing intensity in say, red, or some other color,
beginning at the note's initial X position that fades out as
you move to the right, then superimpose my existing note
outline in a contrasting color over that. Or whatever else
you want to try out.
Well, maybe one gets used to it after working on the editor ... I will
install Gneutronica and make a more insightful feedback :-)
Thanks. It's not anything like a perfect program, so don't
get your expectations too high.

- Midishare (can be driven in Java, Lisp, ...)
*provided that I can

http://midishare.sourceforge.net/
I work with MidiShare quite a bit, and I have to say that if you get
it going on your system, it really is one of the nicest,
best-performing MIDI API's around .. of course the fact that it comes
with a Sequencer lib that supports up to 256 tracks is a bonus too ..
;)
That said, it may not be quite "ALSA mainstream" enough of an API to
warrant usage, but if you have control over your system and get
MidiShare.o built and in use, you've got a damn fine MIDI API,
oft-overlooked ..

I wrote a bunch of control-rate (midi) sequencer code in python that
sends messages via OSC to supercollider. I even incorporated it into a
QObject so you can just slap it into your PyQt4 UI, as I did mine.
PyQt4 is great...
