Welcome to Reaperworld. It’s an alternative universe, in which a “2.4.5″ update is huge. Released yesterday, it’s a new build for what might best be described as an “indie” DAW from the original creator of Winamp.

Check out the full feature list, but here are some highlights:

• “Solo in front” for easier soloing
• Track folding for MIDI to hide unused / unnamed rows
• Multimedia keyboard support, so you can use those silly, useless buttons PCs have for something cool
• Mute fades, so you don’t get that annoying pop on muting
• A ridiculous number of MIDI workflow and technical improvements

What’s really nice is I get an overwhelming sense that they’re improving the kinds of arcane MIDI and plug-in details that users would want improved. You know, there are all sorts of little annoyances you find when working that developers probably don’t think of. Those kinds of VST and MIDI improvements might not make big headlines at NAMM or in magazine copy, but then, that’s why so many users pour over release notes — these are the things they actually encounter working.

If you’re interested in using Reaper, now is the perfect time to point out the work Peter Dines has started trying to optimally combine Reaper and Native Instruments’ Kore, with Kore providing various live performance, sound design, sound cataloging, and synth/effect features:

Mac Experience?

I haven’t really had a chance to try the Mac beta; anyone on Mac had testing experience?

Open-source music and audio is finally delivering the goods: useful and unique tools that make sense even alongside commercial/proprietary software. And as a sign that the mainstream could get a taste of these tools soon, Intel is exhibiting at the massive Las Vegas CES consumer electronics show with Transmission, says Trinity Audio’s Ronald Stewart.

Transmission is Trinity Audio’s open source software bundle and live Linux distribution. It’s built for Trinity’s Linux-powered Trinity mobile studio device, which we’ll be seeing more of soon. At CES, it’s running at the Intel booth on the Samsung Q1 Ultra Ultra Mobile PC (UMPC). (The advantage of the Trinity over the UMPC for audio folks: XLR jacks, among other things.) But you can also run this free software on your PC — try the live CD link below. Haven’t tried it on Intel Mac yet, but that should work, too, theoretically.

Audacity [the open-source waveform editor]

Burn is a cd burn app

DJ is IDJ for live podcasting ( i love this with a mic)

Drum is Hydrogen [the simple but fun software drum machine]

Mixer is the Gnome ALSA mixer [for mixing virtual channels of audio on your system -- something not nearly as functional on Mac or Windows]

Mixxx 1.6 beta (rips with the touch screen grabbing the tracks and faders)

Record is Ardourino (Ardour is so awesome) [the open-source DAW]

Sequencer is Qtractor (another great app)

Synth is amsynth

Upload is an ftp app [so you can upload your tracks]

Zynaddsubfx is another great synth

For more description and links to the individual tools — an excellent selection of the creme de la creme on Linux — check the Transmission site. (warning: auto-plays audio!)

But no need to have a UMPC or Trinity device to give this a spin. This live CD will do the trick. For Mac users, it even includes the native (non-Linux) Ardour for Mac, an excellent free and open source DAW for Mac users.

Even as someone dedicated to proprietary software I really can’t live without (hello, Ableton!), I think there’s huge potential in using these applications for specific applications (like mobile devices), for collaboration, and file exchange. If we were really lucky, some of those major developers would start to build in support for, say, Ardour’s file format. But that’s the subject of another story.

Below: the Trinity mobile device getting celebrity treatment.

JazzMutant’s Lemur touchscreen turned a lot of heads, at least as a concept: precise, multi-touch tracking that could follow all ten of your fingers independently, and interactive, custom controller touch layouts looking like something out of Star Trek: The Next Generation. That was the good news. The bad news: difficult assignments for OpenSoundControl (OSC), extra steps required for MIDI (especially in the early versions), controller layouts limited to pre-defined objects, no tactile feedback as with physical controllers, and a steep price (US$2500). Some dedicated electronic musicians loved it, and were willing to put in the time to use it. Many others just shrugged and stuck to far-cheaper, sometimes more-flexible hardware knobs and faders. Still, many at least acknowledged that the Lemur could be a first indication of the future of hardware, even despite its flaws.

Now, JazzMutant is back with something they call the Dexter? All-new hardware, right? Nope. The unit itself looks identical to the Lemur, which is too bad — part of what made the Lemur experience feel incomplete to me was its bulky and boxy case, which failed to reflect the innovation of the screen. A lower price? We just don’t know yet: pricing and availability is TBD.

What the Dexter is designed to do is to work more fluidly out of the box as a traditional DAW controller. There are pre-defined layouts for Cubase, Sonar, Logic Pro, Nuendo and Pyramix, and lots of new object features specifically designed to DAW editing.

Looking over what they’ve planned, I immediately see items that makes me say immediately say, “slick!” — and others that make me go, “huh?”
