Here's a new screenshot:

Here is an mp3 I made today while testing it (the project in the picture is the project).

The v0.5 preview release should be ready within 2 weeks. The main big features that are not done yet are envelopes and busses, and there a lot of small features planned that are not in yet, but having said that, it's coming along very nicely and there's already a lot of great features and customizability.

Some features added since the first update on this that are especially nice:

+ DirectX plug-in support

+ peak building on the fly when recording (no more waiting after long recordings to build peaks)

+ media item segment looping (so you don't have to actually create a new file to make a loop of a part of another file)

+ you can arm/dearm recording for channels during playback (soon you will be able to while recording)

+ you can change channel recording sources while recording

+ plug-in architecture

+ dynamic audio generation capabilities, i.e. "click track" item.

+ you can use mp3 (VBR even) and OGG (multi-stream even) files directly in your projects

+ I updated NINJAM's cliplogcvt so that it can output to the REAPER project file format directly, making it very easy to use REAPER to edit/remix NINJAM sessions.

And of course, the most of the more standard features one would expect are done, such as:

+ High quality 64bps processing (though higher quality resampling modes still need to be finished)

+ Unlimited undo/redo support

+ Item fades

+ Snapping

+ Automatic crossfades

+ Selection loop support

Stay tuned. If you do some creative URL modifying, you can get a tasty treat.

The new project (REAPER) is coming along nicely, getting very useful. Hopefully something fairly complete will be ready before Christmas, that's my goal at least. Christmas presents for all. It seems the fall is a productive time for me, often. Though I think I need to take a few days off of it, having spent about 2 weeks of solid work, well, has taken its toll.

Flew a new collective pitch R/C heli for the first time today, woot. It's really amazing how the technology has come along since I was a teenager. Also, Brennan got me RealFlight G3 for an early christmas present, and it's pretty awesome (aside from the complaints I do have, it's a tremendous amount of fun).

Brennan and Biderman and I had a nice jam today. It's so much fun, especially when we are able to pay attention to what everybody else is doing and adapt and coordinate stuff. Coffee seems to help a ton, too. In general, finding myself more able to play lots of different things is very satisfying and fun..

OK so I've been spending the last 9 days or so writing a new program, called REAPER (which stands for something along the lines of Rapid Environment for Audio Prototyping -- but I just like to think "don't fear it" or "reap your harvests" or whatnot).

Now I know, there are many products that fall into this category, ranging from crappy open source to not so crappy open source (requiring linux) to crappy closed source to super insanely expensive hardware-dongled closed source. So why am I writing yet another editor? Because I'm making something that fits the category of being exactly what I want to use. It's mostly like Vegas (without the video capability), but with features that I always wish Vegas had.

I will be posting some alpha builds soon, but in general I haven't decided on how to release it. I'm really tempted to do some nag-free shareware again. At the very least it will have very sensible public plug-in APIs that make it easy to extend, and maybe it'll go open source too, I don't know. We'll see. For now, here's an image:

There's a lot to do, which I'm excited about, but it's already quite usable, and already does things well that other software I've used does poorly. But now, I need to go do everything else. Fun fun fun. Stay tuned, I'll be posting the alphas in here, and hopefully a v0.9 beta type release by Christmas. The biggest obstacle I face is DirectX and VST plug-in support, since the APIs for hosting them seem to be a pain (well, DirectX, anyway, I haven't looked at the VST hosting API yet) . At the moment I just have Jesusonic integrated, which is super easy (since it has a reasonable API that doesn't require the disgusting monster that is DirectShow). Keep an eye on the comments of this article if you are interested, I'll likely just post links in there...

Finally, NINJAM users, expect a new release of the Windows client in the not too distant future, with some of the improvements to the audio system I've been making for this. Specifically, increasing the accuracy of the timing of the recorded loops (currently it's not too far off but it could be a lot better).

Here it is. We had a fun afternoon making it, too. It's very weird, be warned.

I spent some time improving and cleaning up the script that powers this portion of my site, which was originally Brennan's hlscript, and am now releasing it as "hl--". I'm intending to backport much of the new functionality to hlscript, since hl-- lacks many of the features that hlscript has.

Also, I updated PathSync a few days ago, with an option to help deal with daylight savings time anomalies.

...but had some fun when I got a small cheapo R/C helicopter, and made this little video. Now if I can just learn to try not to impress the camera...

Had some weird terrible nastiness that I don't what it was. Some sort of flu or food poisoning or some shit, bleh. There went the weekend. At least I had a wonderful wife(!!) to take care of me.

The video from the show is up, currently in three formats (CAUTION: if you lack a sense of humor your probably don't want to watch these): high quality xvid/mp3 AVI, low quality xvid/mp3 AVI, and as a flash video on youtube. Thanks to Newton and Penny for videotaping it. Overall it went pretty decently, we all fucked up a fair amount, but nothing too catastrophic. Forgot to play a Led Zeppelin cover, though.

Apparently in the top 10 things done wrong by web logs (which I will link to here to be mean), I score a 8/10 (meaning I make 8 of the 10 "mistakes" listed in the article). The only ones I miss are 9 ("Forgetting That You Write for Your Future Boss" -- rather, by posting what I post, I ensure that the only people who would hire me are the people who I'd want to work for), and 10, because I have my own domain. hot damn.

Anyway, here's a new topic. Friday night we're playing at the Cherry Bar on Folsom in SF, going on around 10:30 or so I think, in case anybody wants to come by. I don't know why I'd mention it here, since the three people who read this are most likely geographically and/or spatially challenged.

So I'm sitting in the dining room of a friend's house, on my laptop, listening to random music-like things. I think soon I'm going to make something like Debris for audio, specifically for NINJAM recordings, since they are in nice little chunks with some somewhat relevant metadata. Could be interesting, depending on how much intelligence I can build into it.

A little burnt out on the portable console hacking-- primarily because of things that are really hard to debug (for one, it seems that if I do an uncached write (the second to top bit of the address set) to memory, then soon after do an uncached read, it doesn't get the updated value. Which complicates things... The whole process of building, copying, running, repeat is a pain too. Anyway.

Get to move my work space soon, going to get a bunch of bandwidth at the new location, too. Yum.

And after this weekend, we'll have to get practicing for our show.

Speaking of music, got a fretless mexican fender jazz bass. So tasty. It has lines on it, thankfully, so it's not too hard to play, just gotta pay more attention. Here's a little mp3 of me testing it out on NINJAM.

Thanks to a lovely birthday present (thanks rOn!), I've started playing around with writing stuff for a certain portable console, we'll just call the XYX. I'm pretty impressed with the XYX thus far, and look forward to learning more about it, woot. Time to learn MIPS assembly and retarget Jesusonic for it--oh wait, this thing lacks audio input, sad.

I spent the evening last night and part of today doing something that ended up being very easy, but produced crazy tasty results -- I made Jesusonic support multiple sub-channels, where each one runs concurrently, and their outputs are mixed, and the currently selected channel gets the input from triggers/knobs/audio. This lets me have banks that can be drum machine, bass loop, guitar loop, etc. and switch between them using the footboard, and control each one, and so on. I also made a loopsampler-granul that lets you program the loop granularity, so you can make your loops perfectly timed to synchronize. It's so awesome, for me at least. Tempted to start making songs live with it. Here's a good one of me screwing around (though without the setup, but I'm sure I could get the setup process recorded to sound decent). Anyway, gonna go try it on the actual hardware, which shall I mention, I just added a backlit keyboard too (though I haven't finalized the mounting of yet). Getting my patches worked out for the show on Oct 28th, but tempted to make some for jamming alone, just to mess around at some point.. heh. anyway, fun fun. I'll post Jesusonic 0.992 up with this functionality once I test it some more, so maybe a few days...

After reading this comment (from this page): "Dungen were great 60's fun when playing their "proper" songs, but again jumped into too many instrumental jams with flute solos and the like. They need another album of actual tunes to round out their set, IMO."

Funny how different tastes can be.. When I've seen Dungen live, I liked the album songs fine, but the instrumental freakout jams with flutes and everything were JUST INSANELY GOOD. They would stop playing at the end, and I'd want more. MORE!

In other news, I did some more flights of my R/C plane, and recorded this video. I can feel the novelty wearing off (of the video aspect), I wonder how long until I am flying and not videotaping it... Oh yeah, here's my self portrait...

Let's see, what else? I fixed the sustain pedal on the Rhodes I got, seems one of the pins holding the long thing that pushes the dampers down was missing, so I just cut a bolt to fit and reinstalled, and it works like a charm. Woot. Tsk tsk Darren or whatever your name was for selling me this without the sustain rod, so I wouldn't know (just kidding I'm sure he didnt know anyway).

OK so here's something that might actually be interesting to people who read this: I'm planning on GPLing Jesusonic. It's about that time (if anybody has any question as to why I would choose the GPL instead of a BSD license, see my previous article).

Finally, here's a little (extremely rough) take of a song that Dave Wiener and I made back in August, using a poorly maintained (but still lovely) grand piano.

Part II - Making Open Source Work

From my experiences, there really seems to be a right way and a wrong way to begin an open source project.

The Right Way

+ If you haven't already, write a usable working proof of concept of your software.

+ Do NOT create a sourceforge.net project for your software (see below).

+ Make a simple web page for your software. Provide downloads for the source and (if it runs on Windows or Mac) binaries. Perhaps even bundle the source with binaries, if it's not too big.

+ Put an email address on the web page with a link that says "send updates/patches/requests/etc to ". It often is also useful to put a list of things that you are intending to add, i.e. a "todo" list.

+ Continue to update and USE your software.

The big push here is that a sourceforge.net project should only be created for a project once it has enough people working on it to warrant it (i.e. more than a few).

From my experiences it is much easier for developers to get involved with a project if they can download a source tarball or ZIP file, make their changes, and send them back to the project owner, who can then merge changes appropriately. While the project owner should definitely be using some sort of version control, setting up a CVS server for other contributors isn't really that important, at least until other people start doing a very big percentage of the work, and having it as the recommended mechanism for access initially is a really bad idea, because the barrier of entry is higher.

The other things I suggest are:

+ If you use other SDKs/libraries, include a text file with the names, versions, and (preferably) download links for those SDKs/libraries.

+ Try to use only the most common libraries, to make it as easy as possible for other people to run and build your code.

The ideal scenario is, you create the initial version of software and thus begins the cycle:

+ Someone finds out about your software

+ That person wants a particular feature or functionality, so they add it

+ They send you a patch, you merge it into the main release

+ Repeat.

That's really all there is to it. Later on, if you have many people actively working on your project, you might want to consider public CVS etc, but even that isn't really that helpful, as you'll only want people whose code you trust to have commit access.. anyway, hope this helps people! I know it might obvious, but hey, that's why I named this post what I did.

So I built my power filter for the camera in my plane out of a 1000uF cap and a 2.2ohm resistor, and behold, it worked like a charm. It was extremely windy today (really bad), but I couldn't wait, so I found a field that was at least mostly empty (Balboa Park), and did a couple of test flights. I had to fight to keep the plane in control, the wind was so great and gusty, but I managed to (most of the time). Using this recording setup, I managed to take this lovely video (about 15mb, XVID/MP3 AVI) of 2 of the flights. Tomorrow I hope to do some longer, more controlled flights, if the air is calmer. Woohoo! So much fun.

Test flew my RC plane with camera mounted in it today, was fine. Balance good, weight not too bad, added power draw seemed OK, etc. Didn't have the receiver for the camera, though, so I don't have any video footage of it.

The main thing left to fix is that when the motor is on, the power gets so noisy that the camera starts fucking up. So after researching online, I've decided to go to Radio Shack in the morning and buy the appropriate resistors and capacitors (well, just one of each really), and build a lowpass filter. Judging by how the video looks when the noise is there, it appears to be correlated to the speed of the motor (the motor probably spins at upwards of 2000 RPM), so it seems relatively easy to build, say, a 30Hz lowpass (which using a 2.2 ohm resistor and 2200microfarad cap will give me a (workable) voltage drop of 0.2 volts, at 80mA load), which will hopefully take care of it. I'll buy some variety of resistors and capacitors to tweak the filter once I see how it works, too. Fun fun, math meeting electronics, mmm. I'm not sure what the frequency response curve is for a lowpass like this, so I'm shooting really low. Anybody have any experience with doing this? :) I guess I'll find out if I'm completely wrong...
