Mobile Music Fun: A Comparison of Some iOS Music Apps
On some recent flights between San Jose, CA and Des Moines, IA, I spent a lot of time with some ipad/phone music apps, BtBx, FunkBox, and a bit with Molten. I have a few music apps on these devices, and I find one of the best places to get absorbed in to them is to fill the gaps of a long wait. I’ve tried using these things in my living room, but there’s too many distractions. So on my most recent flight, I tried out some apps that I’d recently purchased, but hadn’t really explored.
They all have their strengths and weaknesses, and I wish I could somehow combine them all into one app with the simplicity of BtBx, the sounds, ease, and mixability of FunkBox, and the expansive possibility of Molten. Regardless of my longing for feature creep, it still was a hell of a way to pass the hours and forget that I was in an uncomfortable chair, trapped in a metal tube, 35,000 feet above Middle America.
BtBx

BtBx was definitely the most fun. I kept coming back to it, mostly because I had some melodic control along with the beats. The small form factor of the iPhone focused me on making music, and the interface makes it pretty easy to get around the various features in the small space. It has the usual drum machine sounds of bass, hats, snares, and claps, but adds an extra kick sound and some “instruments” so you can add some melody to the 16 steps. Each sound has a filter, and you can reverse, speed up and slow down a sound with the keyboard, so even a lame cowbell sound can turn into something cool, or a clap can turn into a lo-fi ambient soundscape. It is almost the perfect little step sequence sketch pad, except that there’s no way to export the results as MIDI or even WAV. It’s a bit hearbreaking to get attached to your groovy creation, only to have it all stuck in the device. To get some examples out, I just hooked up a cable and recorded the iPod Touch analog output.
Here’s one example of triggering different patterns. I made all 16 patterns on my iPod Touch and then used the pattern sequencer to jump around to different parts:

Here’s another example that evokes a low-budget horror movie sound track, where I created some patterns for an intro, then got to the main pattern. Once there, I used the BtBx controls to drop instruments out of the pattern to keep things moving and changing and leave room for some zombie’s head to explode or a knife to glint in the corner:

I did this on the iPad, just to try it out there. I found it crashed a couple times on the iPad, but was totally solid on the iPod – fortunately I saved my work!
I’d love to take these patterns, put them into Ableton Live, expand them, refine them, and apply some of Live’s instruments and devices, but with no way to export the MIDI, I’m stuck with this fairly limited, lo-fi mix. At best, I can record each pattern, cut it up in an audio editor, and use the WAV files to mix. I also would love to be able to copy a pattern from one slot to another, as it would make it much easier to create variations and more related pieces. Finally, it’s worth noting, as it’s not obvious, the “Volume” slider at the top is not “master volume” but the volume for the selected sound in the mix. That took a while to figure out, so I thought I’d randomly pass that on!

FunkBox

FunkBox is a fantastic drum machine sequencer on the iPad. It features big, pretty controls, a gaggle of the best vintage drum machine sounds, and 16 playable pads, so you can overdub and record beats into your sequence. Once you program your patterns, you can lock a drum machine and tempo to each pattern, or use a master drum machine and tempo. Mixing up your patterns is really fun, as it doesn’t restart to the 1 when you change patterns, so you can remix on the fly. With each sequence on its own set of sounds, you can get some really funky mixes going.
I made a set of patterns and did a quick mix, jumping around to the different patterns around a primary beat:

Given the seamless remixing, with a good set of patterns (you get 3 sets of 16 patterns for your project), there would be no shame in using this thing in a live performance, remixing your patterns around other stuff. You can export patterns to WAV and/or MIDI. I found myself wishing for a metronome button, since every time I started a new pattern, I had to program a rimshot or something to give me a click track.
Unlike BtBx, it’s easy to copy a pattern from one slot to another if you just want to do a set of variations. With a level mixer for each sound right in the middle of the screen, you can tune each pattern to have its own character: the mix is set for each pattern. Each drum machine has some alternate sounds, so you can swap a ride out for a crash or a clap for a rimshot, for example. There is also an accent mixer, which I didn’t get into, as I was too busy having fun rocking the beats. For integrating mobile work into a studio set on your computer, FunkBox simply kicks ass. No distracting, half-assed effects or excess setup is needed. You can crank out loads of beats and bring them into your set however you like.

Molten

Molten is the deepest and cheapest of these three, with lots of controls 4 pages of 16+ steps for each pattern. It supports external sync, MIDI control, and WAV and MIDI export, and audio copy/paste. It’s definitely the least attractive interface, with slightly blurry graphics and some garish colors, but it is definitely usable. There’s a lot of tweakability for each sound, and it can sync with other apps (like FunkBox). Most impressive is that each beat can be subdivided into up to 9 beats, and you can do weird time signatures and triplets, so there’s some really crazy rhythmic possibilities here. However, I didn’t like the default sounds, so I had to labor to create my own bank, which is akin to having to string your guitar when you buy it.
I think Molten will really shine when I hook it up to a MIDI controller (oh, like a block or something), since, after looking at the specs, I’m pretty sure it will light up the LEDs and provide a comprehensive step-sequence engine for the controller. I hope to feature something on that later! You’ll notice that I don’t have an example file for this app, which is a direct reflection of “possibility vs. productivity.” I was too busy having head-bobbing, stupid fun with the other two apps to overcome my reluctance to figure something out. Stay tuned for when I get it hooked up to my Code, Ohm64 or block: I think we’ll find something good to listen to from Molten.

Of course, none of these apps are going to be the center of production for your next show, but for less than the cost of a crappy hamburger at the food court, you can bust out some great stems, get some great ideas, and stop complaining about how much flying sucks. As a matter of fact, these apps are so fun and productive, you’ll probably look forward to that next cross-country trek, and maybe even hope for bad weather.
