DSMI: New OSX release, new libdsmi for DS, PulseDS working again!

Sunday, April 4th, 2010

A lot has happened with DSMI lately, so today I’m realeasing quite a bunch of updates:

All example apps are now compatible with libnds 1.4.3 and devkitARM r30 (latest versions as of April 2010) and have been updated to the latest devkitpro nds templates. KaosDS, DS MIDI Keyboard and the OSC Example now use the default ARM7 binary, which means they are much less code now. Thanks to Wintermute who kindly provided patches to libdsmi and the OSC Example!

Have fun!

DSMI v3.0 out of beta, now hosted at Google Code, ported to the iPhone!

Thursday, January 29th, 2009

That’s right, a lot is happening with DSMI lately! I’ve ported libdsmi, KaosDS, PulseDS and DSMIDIKeyboard to the new libnds v1.3.1. This library introduces a lot of simplifications, making the code shorter and more readable. For developers, the libdsmi API has stayed the same, except that dsmi_setup_wifi_support is no longer necessary and has thus been removed. For end-users, nothing has changed.

To make collaboration easier, I set up a Google Code project for DSMI, which is now the official place to download the library and applications. Google Code features a nice source browser so you can check out the source code more easily. Also, there is an issue tracker that you can use to inform us of bugs.

One more thing: Collin Meyer has ported DSMI to the iPhone and released the first DSMI-enabled iPhone application! iXY is a Kaoss Pad style MIDI controller that lets you control your synth parameters or light effects with the touch of your fingers. iXY is available from the App Store for 99US cent / 79EUR cent. The library itself is work in progress and will be released soon, so everyone can write MIDI-enabled iPhone apps!

DSMI

It turns out DSMI keeps facing trouble regarding its name. It first started off as DSMIDIWiFi. After I added hardware MIDI support through the DSerial, the “WiFi” part of the name was no longer appropriate, so I changed the name to DSMI. I didn’t call it DSMIDI in order to avoid the name collision with Collin’s DSMIDI hardware hack. It turned out this was the right choice, because fishuyo came along and added OSC support which would have made the MIDI part of the name inappropriate anyway. Now that Collin has ported DSMI to the iPhone, the DS part of the name would have to go. Nevertheless, we decided on keeping the name in order to avoid confusion. If anyone has an idea for a new meaning of the DSMI acronym, please let us know :-)

DSMI v3.0 is out, supports OSC!

Monday, December 1st, 2008

Thanks to Tim Wood (fishuyo) DSMI now supports the OpenSound Control (OSC) protocol!

OSC is an emerging standard for exchanging music control signals that is much more flexible and modern than MIDI. For example, OSC can directly communicate via network, so the PC-side DSMI server is not required.

fishuyo also made a nice demo of the new OSC capabilities with a Kaoss pad and sliders. It comes with a pd patch that is a nice little synth. Check out the demo’s source code! OSC is really easy to add to your application. And it’s the future! So, get libdsmi v3.0 now!

Share your Pocket Physics Sketches - Now with Flash!

Saturday, April 26th, 2008

Sh4wn is running return1.net/site/pp, which is a great place for sharing your Pocket Physics productions and for browsing though what others made. Recently, the interactive flash player by emeric was included in the site so you can now play back the sketches online and even interact with them! Accuracy is not 100% but I’m quite impressed how close it is.

Even if you don’t have Pocket Physics, do check out the site. Thanks a lot to Sh4wn and emeric for their efforts!

libntxm v0.2, now on Google Code, Coders wanted!

Tuesday, April 15th, 2008

For easier integration with NitroTracker, libntxm now includes editing functionality under the hood. There aren’t any changes for the end-user, except for maybe one or two new supported effects, so if you use libntxm 0.1 there is little reason to upgrade, but:

libntxm is now used as part of NitroTracker instead of being just a stripped down version of the NitroTracker arm7 code. Also, libntxm is now hosted on Google Code and has an SVN repository there. So, you can now easily add new features to libntxm, and I can integrate them into NitroTracker just via a simple “svn up”.

libntxm project page on Google Code

Currently, I’m searching for someone who wants to implement support for loading / saving new file formats like .it, .s3m, etc. Also, .wav saving and .xi loading / saving would be useful. If you want to help out, please contact me!

Pocket Physics 0.6

Saturday, March 15th, 2008

After a lot of optimization and bugfixing work, I’m releasing

Pocket Physics 0.6!

In this version I focused on speed and stability, and I think it shows. If you compare the speed to the old version, you think up to now everything was in slow motion! There are no more spontaneous explosions and no other randomness. If you restart the simulation, it will behave exactly like it did before. Also, it has become much more stable. In fact I cannot get it to crash any more! If you can, please tell me how!

Check it out! Although I didn’t add any new major features, I think this is a huge improvement!

Fixed point support officially added to Box2D 2.0 SVN!

Saturday, March 15th, 2008

I’m happy to announce that fixed point math and the DS target are now officially supported in Box2D! So if you were using the fixed point patches before, you can now just check out the latest SVN version of Box2D. Check this thread for further updates! Huge thanks to Kavaler for his help with the fixed point port!

Pocket Physics v0.5

Thursday, February 21st, 2008

Sometimes when I added a new feature to Pocket Physics, I thought “This is actually quite fun!” In this version, I added the moving tool, and I must say: This is seriously an awful lot of fun! You can now directly interact with your sketches by grabbing and throwing objects with the stylus! Also, editing has become a lot easier because you don’t have to delete and re-draw objects to reposition them. Try it out, it’s really cool!

Get it from the project homepage!

Again, a big thank you to Erin Catto for making the amazing Box2D library!

A note on stability:
Pocket Physics uses a modified version of Box2D that uses fixed point math instead of floating point. Due to this conversion, a lot of unexpected things (spontaneous explosions, freezes, etc) can occur. I’m working on improving stability of Box2D, but it takes time to track down and fix these bugs, so please bear with me.

Pocket Physics 0.4

Version 0.4 is out and adds saving and loading! Never lose your work again, and share your creations with others!
