I’m not sure how everyone who owns an iPad uses it for music, but I find myself strangely drawn, more than anything else, to analog step sequencers. With MIDI connections – via a special interface or a standard USB MIDI interface connected via adapter to the tablet – you can even drive hardware. For me, the app of choice has been Little MIDI Machine. Developer Chris Randall has a new application in the analog-style sequencing category, though, called Phaedra.

If you haven’t grabbed it already, you have until the New Year to get it for US$4.99 before the price jumps to ten bucks. And you get an impressive array of features:

  • Multiple buses, with 32 steps max each
  • Programmable note, velocity, gate time, and two MIDI CC outs for each step
  • Send or receive MIDI Clock for sync
  • Use MIDI hardware (via Core MIDI), other apps (using “background MIDI” or OMAC), or your computer (networking via a MIDI Network Session

Phaedra for iPad [iTunes Store Link; you’ll need iOS 5.0]

I wanted to know more about the creation of Phaedra. Developer and musician Chris Randall, known for his work with boutique plug-in maker Audio Damage, released this under a new moniker, Naughty Panther, which does iOS and MIDI development. Chris has been known to mix old and new, as with his musical use of the Apple II. Here, he gives us some insight into how he went through the design process on this new tool.

Develop for iPad, but sketch on a more traditional tablet – the paper kind. From Chris’ notebook sketches for Phaedra.

CDM: How do you sketch out the UI on a project like this? Paper and pencil?

Chris: Normally I just make notes in a little Field Notes notebook as I think about them — I carry one everywhere — then once I have a clear mental image of what I want to make, I just bust it straight out in Photoshop (or, for skeuomorphic interfaces like this one, a combination of Photoshop for the panel and 3D Studio Max for the knobs and buttons).

What inspiration did you consider as far as hardware?

Adam sent me the page for the Moon Modular 568 “Sequential Trigger Source” and quipped that it would make a fun iPad app, and I kind of ran with it. (Their site is a frame-a-thon, but ’tis here: http://www.lunar-experience.com/home.html) As you can see, the UI for Phaedra closely follows the Moon Modular design. The functionality diverges quite a bit, though. Once I had the initial look, I just started adding features I personally thought would be nice in a step sequencer. Then the beta testers had some more input. And now that it is out, I’m getting a ton of great feature requests from the users. The next update will have some cool tricks in it, provided I can figure out how to code them.

What hardware would you recommend for connecting MIDI?

The best MIDI I/O situation for Phaedra is an Alesis iO Dock. Hands down. I have tested it with a half dozen MIDI interfaces via the [Apple] Camera Connection Kit [for connecting driverless USB MIDI interfaces], and they all work fine except that $5 cheap one that people buy from Amazon, which unsurprisingly, has problems. Phaedra also automatically creates a virtual port and connects to all virtual endpoints running on the iPad, so it can drive NLog Pro, Animoog, whatever. And it also is [Apple MIDI] Network Session aware, so it can just work over wi-fi.

I’m going to add OSC output as an option in the next update, I think. I’m still thinking about how to implement that, but it seems like it would be handy, and then Phaedra’s abilities would be greatly increased.

I’m also adding trigger outputs via the audio ports, so you can use Phaedra to clock an external modular sequencer like Makenoise René, or a pre-MIDI drum machine. I’m giving it 48-ppq clock for Korg drum machines, 24-ppq clock for most every other drum machine, and arbitrary rates from 16-ppq on up to 1-ppq for driving modular sequencers and your Monotribe. This should be handy, and will be sample-accurate in line with the MIDI clock output.

    Everyone? No iPad here. No need for it. No wish to get one.

      So, why are you reading a review for an iPad based sequencer then?

      • Andy

        I love AD plugins and I was just curious about this. I didn't even read this review.

      Imagine if the all the CV guys had that same thought process when MIDI came about?  Damn that's a scary world right there. Glad this guy isn't running for president. We might STILL be chasing sadamm around Iraq :). 

      Here's a thought. Instead of thinking of the iPad as a "Apple" product,try thinking of it like,say,a Korg product or now even, a Lemur product. Not only does it run Lemur(used iPad 1 can be found for +/-$200+$100 in musical apps) or equally high powered VSTi quality synths and utilities,but,and this is a big but,it can do almost damn near anything or more then a Laptop in the same price point could do…..holly hell! What kind of new dangled fangled technology could do that?  Well my friend,crawl out of your hole,put on those shades because the future is BRIGHT! and it's not waiting for you either. As a musician always on the look out for the best and brightest in music tech how could you NOT consider the iPad. Whatever you alignments,this is something any musician should have on their top 10 list of new musical hardware.

    Quite dope indeed!

  • DBM

    It is a great app .

  • youngcircle

    Just grabbed it, already love it :). I too have a thing for iPad sequencers, to me it’s exactly what the platform does best- a flexible interface for other instruments more than an instrument in and of itself. Though Animoog is sort of making me reconsider that. Another sequencer I love, and one that you can edit yourself, is a Reaktor user ensemble from the NI site called Berliner Monosequencer. Can’t reccommend it enough, as it comes with a touchosc template thats easy to mold to your own. https://co.native-instruments.com/index.php?id=userlibrary&type=0&ulbr=1&plview=detail&patchid=10246

    Does it also support WIST or is that not interesting enough? I figure: anything with a clock should be synchable eventually. I don't find the $5 MIDI adapter to be that bad – but then again all my MIDI devices date before 1988.

  • systmcrsh

    funny, i'm currently writing some software myself… i use a similar paper tablet w/ pen. mine's a rhodia tablet, handy 🙂

  • I don't think I'm capable to cope with the buttons together at one time.

  • Bought this app last night and successfully ran sequences to Animoog. Results: Incredible! Looking forward to whatever additions you add to this already essential app. My background: I build lunettas out of cmos ics and dabble in modular effects as well. I dig lo fi and Hi Fi; old tech and new.

    The ipad has proved valuable to me in creating music and has allowed me to create instead of troubleshooting a DIY build or shelling out Big Bucks to be satisfied. Welcome to the future.

    I tried the same last night but couldn’t get it to work. Animoog shows Phaedra as a MIDI input on the SETUP screen, and I have a pattern running in Phaedra, yet nothing is triggered in Animoog.

    Maybe I’m just missing something simple — would you be able to write up a walkthrough somewhere or post a video? Thanks in advance.

    Will it sync via WiFi?
    It would be great to use it with Animoog and sync it with Live.

  • Henrik Lindal

    Sounds like the next update will be very good!

    This app is really good, but after a day of playing around with it just with Animoog, I thought things would be amazing as soon as I put some beats behind it. One problem: I set a tempo in Phaedra, but it’s actually outputting about 1 bpm off. Not fun!
