I developed a DS based musical toy to teach myself how to use the PSG (Game Boy style audio) on the Nintendo DS.

Neat! Now, possibility to use different (own) background beats and scales on the fly and this would make it to the next live. :)

Very funny, and the music done with it is quite good!
One thing, you probably used an old version of ndslib, the touchscreen code is bugged. It's not really that important for this app, but I prefer to tell you ;)

I used the most recent libnds, but it uses a custom ARM7 code (taken from one of Chris Double's examples) to have more control over the PSGs. Is it possible to use the newer touch code while still customizing the ARM7?

I changed the ARM7 code to call touchReadXY() of libnds. If you've been having touch problems, please re-download it (from the same URL).

I had a touch screen problem with the old version, and I'm having the same problem with the new version. If I touch the stylus in the upper right corner of the screen it registers the touch a little lower and to the left. The same goes for the other three corners. The only place on the touch screen that provides an accurate result is the center of the screen. So if I touch the center and then move the stylus to the left, the dot on the screen will follow, but it doesn't go as fast as I'm moving the stylus, so it can't ever reach the edge...

In the examples folder that came with devkitpro (you did install the examples, didn't you?) there should be a template that allows you to customise the ARM7 side, with the newest ARM7 touch code. But then again, I still haven't upgraded to r18 yet, so it may still be the old template.
EDIT: Corrected "temple" to "template"

When was the last time you went into settings (hold Select+Start+power on and click the DS that looks like two file drawers icon at the bottom) and calibrated your touch screen?
And yes I did look through the examples. It might take me a while to get up to speed on this new platform.

That's odd.... calibrating the screen worked. I've had this problem before in other apps and calibrating the screen did nothing.

This seems to be true of all cases. Anything using the old touch screen code will not properly use the calibration values, and as a result, if the DS screen responds wierdly before calibration, it will still respond wierdly after that calibration. THe new touch screen code is not affected by this issue, and will work correctly after calibration.

By the way, I like a lot your fading square. Adding some customization to this app (changing rythm and music patterns, adding some background,...) could make a very great one. Keep up the good work!
#82342 - derula - Fri May 05, 2006 12:41 pm
The game is... like... funny. I would love to see more levels ^^.
But what I found out: it may help us to locate the touch issues that are still persisting. I don't know really if the random presses that sometimes occur while lifting the stylus are software or hardware issues, but they seem to occur while you only press the screen lightly, so not only after removing, but also if moving with light pressure. I tried to move the stylus over the screen with only a very light pressure and moving speed, and there where all random presses, but these presses followed some kind of rule, they were all aligned as a line (with a random difference from the line) that went from the real touch point 1.5 inches or so left-down. I don't know if someone had already found out this while trying with the touch thing (actually i cannot imagine no one has), but I just said it now.
Sorry for off topic, tepples, have mercy! *beg* ^^'

I found this too, and I may use AXE as a test platform for rejecting the "outliers" that happen with light pressure.

It's still on the topic of this program. But if someone adapts the source code to make such a test platform, that's a new topic.

Oh w8! i run the file on the DS.. and I see the effect of what the touchscreen do with the sound.. tried with dualis before and the sound didnt change over there...
(well.. I just tried again on dualis.. and it works just like the DS :S weird :D)

#82406 - dustin - Sat May 06, 2006 1:17 am
Man, this is great fun. The only thing I found a bit odd was when I tried to just tap out patterns, not drag the stylus. Quite often a tap won't register a sound, like the screen would be drawn on but there wouldn't be a beep or anything. I'm assuming this is because it only plays the beeps when they are in time with the music and I'm a bit off or something and not because of some bug right?

The pen has to be down at the beginning of a 16th note for a note to play. Eventually, you'll get the hang of the timing. Do you also fail in DDR?

No, I'm fine at DDR actually. I only noticed it happening when I tried doing it on odd beats that weren't really to the music so I assumed it was something like that.

My faith in DS emulation has been restored, to a point: - NO$GBA 2.2f (2006-06-18) runs AXE without sound.
- Dualis (2006-05-02) runs AXE with sound.
Dualis is not for everyone. People with devkitARM R19 may experience incompatibilities, glitches, and crashes; some were bothered enough by these symptoms to go back to musical CF cards. Ask your doctor if Dualis is right for you.

if you are planning to update, it would be awesome of you if you included a button that turned off the background beat so we could add our own*, maybe even from the ds drum machine. =)

#96825 - Omegas - Sat Aug 05, 2006 7:49 pm
The people at Boozembly 2006 (a shadow party of Assembly 2006 demoparty) just loved the app! We played it through my small boombox for like two hours straight. :) The only problem is that the dusty environment combined with some frantic stylus work left several nasty scratches on my DS touch screen. :(
We also came up with many ways to expand this little app. Like adding different drum patterns (which you could change mid-song usind the d-pad?) and assigning samples for the ABXY buttons. Maybe I'll have a better look at the source code and try adding some of this myself...
#96836 - The_Mayor87 - Sat Aug 05, 2006 8:50 pm
Do'h! i didn't realize the source was included when i first downloaded it!
here's a version without the background beat, if anyone wants to add their own later.

#96900 - daninski - Sun Aug 06, 2006 11:23 am
could we get a version which not only has no backing track but plays a constant note when the touch screen is pressed, and that modifies when you move the point? that would be so perfect to use it as a live instrument.
for some reason those rapid share links never ever work for me, they say there's an error that might be because i'm on AOL... which i'm not.
#107566 - OrR - Mon Oct 30, 2006 11:26 pm

#107598 - Dark Knight ez - Tue Oct 31, 2006 10:36 am
I modified its code for the power-up freestyle in AmplituDS if you're interested. I don't think tepples is working on AXE anymore, nor was it ever probably his intent to make it more than this nice little showcase.

That's because it was made on an ancient version of libnds. The layout of the ARM7/ARM9 shared memory changes from version to version. In fact, wintermute has hinted that the shared memory might even disappear entirely in a future version in favor of a completely FIFO-based solution.
What you could do is try taking RAC or memtestARM and turning it back into AXE.

#174178 - tepples - Sat May 22, 2010 5:06 pm
Someone called me on the telephone and asked me to compile a version of this but with the backing beat silenced. He kept me on the phone for 45 minutes explaining why the chiptune scene needs to have a version of AXE without a backing beat. It would take exactly one line of code change to do this (comment out the call to runSound()), but the problem is that AXE is coded against a years-old version of libnds from back when it was still using IPC transfers, and when I try to compile it against the version of libnds on devkitPro Updater, I get a bunch of errors related to TransferRegion. I know exactly what is happening, but I've been out of the DS scene for years, so I don't know the official new way to play sounds. What's the quickest way to get this recompiled without having to completely rewrite the whole thing from the ground up?

the amount of effort required probably depends on how much you used fifo. playing a sound requires a call to soundPlaySample. you need to enable sound first (one time in main would work) with soundEnable(). all of this uses the fifo api in libnds. irq and fifo handlers do not need to be initialized anymore crt handles this now on the arm9.
#174189 - The_Mayor87 - Sat May 22, 2010 8:58 pm

okay here is what should be done..
whether by T, you, me or others. but this program is to good to not develop further.
at the minimum we need a new version with the ability to turn on and off the backing track.
here is the link to the last version, plus source.
http://www.pineight.com/ds/AXE_0.03.zip
Update axe to allow for easy coding updates and ability to still work on DS along with other newer mediums, create a new logo/splash screen for top screen, create/edit logo so it doesn't show homebrew logo. Add a player/save/song load ability, add ability to not play background loop, ability too change background loop, and samples to draw with, change scales, tempo, add a record ability of what you are writing, Add microphone record option so you can record your voice, and then instantly draw with it. If these things can be done it will be the sickest program ever. I am in the process of learning what I can to make this happen, but will need help along the way.
these homebrews have a lot of the code we will need.

Hi tepples! Just check out the examples in devkitARM. All communication between ARM7/ARM9 is now handled using FIFO and you only need to compile for the ARM9 side now.

www.devkitpro.org is down but everything is on the sourceforge page http://sourceforge.net/projects/devkitpro/files/. I think all of the docs are auto generated from the comments in the header files. so, the header files are usually all I look at.
