Xequence | MIDI Sequencer by Seven Systems

Seven Systems released Xequence. This MIDI Sequencer arrives with Virtual MIDI support as well as the promise of Audiobus 3 MIDI in a future update. The v1.0 feature set is pretty impressive, considering this is the first music app from this developer; whose previous efforts include a leveling tool. I really like the look of this one too. The interface looks professional and powerful.

The base app is $5, which they consider a demo. To unlock "unlimited tracks" requires a $9 In-app Purchase.

Xequence | MIDI Sequencer iTunes Description:

I bought this app today and it's absolutely horrible. To edit the piano roll you need to tap the pencil icon and once activated the icon flashes on and off, super annoying. Once you draw a note, you can't just simply drag the note around, you have to click the pencil icon off, select the note, and use these little arrows on the right side to drag the notes up and down. Once you place a note and want to make it longer or move it side to side, again you have to click off the pencil icon and use the move-side-to-side or note-length buttons. All these things could be accomplished by simply tapping, holding and dragging notes but these geniuses decided to reinvent the piano roll. It is super convoluted and doesn't work like almost every other piano roll editor on the market (ModStep, Gadget, Auxy, etc.) I have a ton of experience with piano roll editors and this is one of the worst I've seen. Now for my biggest gripe, sustained notes don't work! For example, if I draw a note that is one bar long, it only plays a 1/64 note. All it will play is 1/64 notes, totally useless. Of the many, many music apps I've purchased, this is the first time I'll be calling Apple to see if I can reverse this purchase. (As I was about to submit this, it just crashed by simply clicking settings button.)

Hi,

sorry to hear that you don't like Xequence. The approach to editing in the pianoroll is actually pretty similar to the one used in NanoStudio, which is regarded by many as very efficient, but of course, that is also a matter of taste.

You don't have to exit draw mode in order to move the just drawn note around, you can just use the handles straight away. However, it's probably easier to just delete the note again by tapping it, and then drawing it in a different place. Note also that before you lift your finger, you can drag the note up and down, and drag left and right to change length.

Concerning the 64th notes, this is the first time we hear about this, and it must be a rare bug. Can you get in touch with me at ae -at- seven.systems so we can discuss this? Also regarding the crash when entering Settings, as this is also the first time someone reported this.

Thanks

EDIT: It is not necessary to use insults and unconstructive criticism when asking for support via our contact form, and it won't help your case. Thanks again!

I just tried to reverse my purchase through the app store but Apple said no. Your app is way too frustrating to use and my day was ruined trying to deal with this. Also, I didn't use vulgar language when I contacted support. Sorry if calling your app a trainwreck is offensive to you but that's what it is. And sorry to see that publicly calling out one of your customers is the way you do things instead of trying to work this out privately. I haven't got a response for my support request but you can take the time to post here. I'm out $5, which isn't that big of a deal, but it's disappointing. I've deleted your app and learned my lesson. I should have waited for reviews before I purchased.

And now you've edited your comment to remove the "vulgar" reference. Anything else you want to do to make me look bad?

So we are paying for demos now? Also, aren't demos prohibited on the App Store? I seem to recall such a rule. Was it nixed? There are certainly a lot of apps on the App Store that are demos, too...

It's not a demo, it's "fully functioning". You are limited to four tracks, with in in-App purchase to unlock unlimited tracks.

Hmmm - if the piano roll uses NanoStudio conventions I may have a look at this as that is the only Midi Editor I really get along with...
I've actually only heard good things in the community (with a few feature requests of course) about this app, and its piano roll. It's positioned in a very useful spot left open by the other cool midi sequencers on iOS (Genome, Modstep, midiSequencer and the hopefully soon-to-be available Quantum - all iPad only and none linear and track-based), and the developer is present, savvy about iOS music, and interested in what users want. Sold.
