Well, That Was Easier Than I Thought It Would Be...

by Chris Randall
 



I've now submitted SimpleMidiPad to the App Store for review. Normally this sort of thing isn't so quick, but for this particular app, which I dearly wanted anyhow, I had all the parts lying around from other projects, so it was just a matter of piecing them together.

I'll make a video showing it in use, and simple techniques for hooking things up. If you don't have the Camera Connection Kit and a compatible USB MIDI interface, or do your music on an OS X machine, you're kinda outta luck. It defaults to a Network Session MIDI node, and looks for a host on your Wi-Fi network. As those of you who have used this know, it's a little tweaky. For realtime CC it's fine, but I wouldn't want to play a synth over it. But it works.

If you plug in a USB MIDI interface via the Camera Connection Kit, it grabs on to that and stops sending to the Network Session. There are a number of MIDI interfaces that work; I have this one, which works fine, but doesn't have anything in particular to recommend it otherwise, except perhaps that it doesn't have integral cables like so many 1x1 interfaces do (and which I intensely dislike.) I was amusing myself for a bit by driving my modular directly from the iPad. The MIDI->CV interface I have only has two CC out, so I could only use one pad, but it works as advertised regardless.

Anyhow, four pads, and you can set the X, Y, and Z CC destinations for each. (Z is just off/on, of course.) It remembers your previous settings, but I didn't provide any sort of preset mechanism aside from that. I put it in at what Apple calls "Tier 2 Pricing," which is $1.99 in the US and Canada, and whatever your local equivalent is. I'll keep you informed on the progress, of course. Should know in a couple of days if it was approved or not, but unless I made some silly mistake (entirely possible) it'll be rockin' sooner rather than later.

Assuming it is approved and those of you that try it provide some good feedback, I'll adjust the framework accordingly and bang out a couple of the other simple ideas I have. Then we'll give porting the Axon sequencer a whirl, which is necessarily a much more involved process. If you have a request for a specific MIDI generator for the iPad, now is the time to bring it up.

Does the Apple app-approving process seem less arcane/arbitrary to you than it did in the beginning? (Maybe I'm mis-characterizing, but I recall some early frustrations).

I figure they've probably been streamlining all this time, right?

The only time I've been rejected it was due to a pretty glaring bug on my end. I've either submitted or hand-held others' submissions quite a bit since then, without any problems.

I haven't submitted anything in the last three months or so, though, and I'm given to understand it is pretty quick now, at least compared to the early days.

I'll use this chance to put in my yearly request for a Muse-type sequencer. I still run an OS9 Mac specifically for the OASYS card it contains and running Turbosynth and Adam's MacMuse sequencer. The Muse interface would nicely translate to the iPad.

"...or hand-held others' submissions..."

Is this a pun?

Being without an iPad, I have no requests.

Does the IWB button only appear after the B have/has posted?

Yes. You can't be with boobs if there's no boobs to be with. That would be silly.

(For the record, boobs can't be with boobs either, as he is boobs.)

I'm still waiting for an Automaton app ;)

But to request the up most needed app .
I would love to see a 16-32 track
midi sequencer with the basics :
Piano roll , Drum xox step , arp
Then add Ableton like clips and envelopes
that can launch both midi loops and send sysex files
Add super tight midi timing with groove selections
from mpc , emu 1200 sp , atari 1040st - lol
wrap it all up with a user configurable control page
and you got my purchase !

Thanks, that's some fairly elaborate comment posting programming. Also, I hear your second sentence is a common complaint in prison. I guess one thing's for sure: boobs is/are no boob.

Okay, so you may write an ios app for yourself, if you can. But, you can only distribute it to others through the store. And for that, it has to be sanctioned by Apple.

I'll assume from your second paragraph that you don't know I've done quite a few apps that are currently on sale in the app store. I'm well aware of what is involved.
