Review of the iOS App, run on an iPad Air 2

A great addition to any DJ's setup, slick smooth and well though out, but needs improvement

BandShift by VirSyn

VirSyn just released BandShift, a new multi-band filter with frequency shifting effect app for AUv3, Audiobus, and Inter-app Audio! The app features 2 XY controllers for real-time manipulation of the effect. BandShift arrives on sale at an introductory price of $7.

BandShift iTunes Description:

BandShift is a multi-band auditory filter and frequency shifter taking a new approach to manipulate the pitch of complex sound sources in realtime. The well know analog Bode frequency shifter shifts all frequencies in an input up by the same amount and thereby alters their harmonic relation and tends to produce inharmonic results. But it's perfect in dealing with transients and sounds smooth even with high amounts of down pitching.

BandShift splits the spectrum in 27 bands and applies a different amount of frequency shifting to each band emulating a harmonic pitch shifting. This gives you perfect pitch shifting for all kind of drum sounds over a vast shifting range of +/- five octaves without disturbing the transients or introducing metallic distortions. The extreme range of shifting gives you access to a vast field of unknown sonic territory.

The possibility to apply different shiftings on each band gives you exciting possibilities: Suppose you have a drum loop which is perfect, but the bass drum is a bit too high or too low to fit in your mix then you can easily get the bass drum shifted a bit down and the rest of the spectrum remains unchanged. But it’s applications are not limited to drum sounds, they’re only limited by your imagination.

### Introductory offer for a limited time ###

Fugue Machine Update

Alexandernaut's popular Fugue Machine was updated with Audiobus 3 MIDI Support, including the per-playhead MIDI destinations hinted at in last week's Audiobus 3 reveal. Previously you had the option of sending Fugue Machine's different playheads out to separate MIDI channels, but now you can actually specify which app (or interface) you want to receive them. In Audiobus 3 this will be even more useful, with the option to add a MIDI effect app on some of the playheads.

The update notes also include a teaser about "something new" Alexander's been working on for over 5 months.

What's new in Fugue Machine v1.3.0:


You can now route each playhead to any MIDI Destination and MIDI Channel — the previous version only allowed routing by MIDI Channel. This makes it much easier to send each playhead to a different app or MIDI Port.

Check out Settings > Midi Output Settings, and notice that each Playhead (1-4) now has its own setting. There's also an 'All Playheads' setting for convenience.

There's now a setting to explicitly set the built-in synth on and off, allowing Fugue Machine to send MIDI and control the built-in synth simultaneously. Go to Settings > Synthesizer Settings.

*Synthesizing sound is expensive! So if you're only using Fugue Machine as a MIDI sequencer, set Synth Enabled to OFF to save CPU resources.

Audiobus 3 brings MIDI support to Audiobus, and Fugue Machine is good to go :]

Fugue Machine now supports State Saving in Audiobus, making it possible to save/manage Fugue Machine patterns via Audiobus.


In previous versions, if you exited the app while Fugue Machine was running, there was a chance some MIDI Notes wouldn't be turned off. Not a huge deal, but it's fixed now.


Although this is a relatively minor update, getting the MIDI Destinations to route properly was surprisingly tricky! I wanted it to be foolproof... which required a system to ensure that redundant MIDI data would be filtered out.

Basically, thanks to this system, you can set the playheads to any Destination / Channel combination, and not have to worry about a connected MIDI device receiving duplicated MIDI messages. Yeee :]

I'm currently working around the clock (for 5+ months now!) on something new, and... I couldn't be more excited about it :]

And yes! Thanks again for your support with Fugue Machine... the new thing I mentioned above would otherwise not be possible.

Ok! Please reach out if anything comes up, and also... if you can... (and I hate asking)... please consider rating/re-rating the app on the App Store :]

All the best,

Mitch from TheAudioDabbler brings us this quick look at the new MIDI functionality!

MAIOLE - No Boras

YouTuber MAIOLE posted this stunning live performance using a classical guitar in Samplr, with a Korg MS20 and Ableton. Holy shit, I loved every bit of this, but I especially loved the way that guitar sounds!

Arpeggionome Pro Update

Arpeggionome Pro, from Alexandernaut, was updated with both Ableton Link and Audiobus 3 MIDI support, making it among the first apps you'll be able to use later this month in Audiobus 3's new architecture!

What's new in Arpeggionome Pro v1.3.0:


Ableton Link is a new technology that synchronizes beat, phase and tempo of Ableton Live and Link-enabled iOS apps over a wireless network. It's awesome. Go to Settings>Ableton Link Settings for more info.

Audiobus 3 brings MIDI support to Audiobus, and Arpeggionome Pro is good to go :]

Arpeggionome Pro now supports 64 bit architectures. Yee.

Arpeggionome Pro has a new setting called 'Matrix Mode', which adds dotted note values to the Performance Matrix.

To try it out, go to Settings >Interaction Settings and set Matrix Mode to 'Halves+Dotted+Triplets'. You'll notice the matrix now has two columns of squares, triangles, and dots.

■ Rows with squares play rates that are perfect halves of a measure — starting at 1/2 at the bottom row.

● Rows with dots play rates that are the dotted values — i.e 1.5x the length of the square row above.

▲ Rows with triangles play rates that are triplet values — i.e. 0.33x the length of 2 square rows below.

In Settings>Interaction Settings, you'll also find a new button at the bottom of the list called "ALT Interaction Settings". This is an alternative interaction state that I recommend trying. It's a bit more difficult to control, but I find the results quite interesting.

Compared to the "Default Interaction Settings", it uses the new Matrix Mode setting and disables Retrigger for all parameters.


In previous versions, when listening for MIDI Clock on the Arp MIDI In port, Arpeggionome Pro read the MIDI clock twice, and therefore went twice as fast as it should. Fixed now.


Hey, it's been a while! The last time I looked at the Arpeggionome Pro code base was over 2.5 years ago! Time is weird.

In any case, I'm really glad to finally get this long overdue update of Arpeggionome Pro out. And I'm especially excited about adding Link and the new Matrix Mode setting.

By supporting Link, Arpeggionome Pro has actually become more playable, and perhaps in a not-so-obvious way. I'll explain…

As you may know, Arpeggionome Pro is designed to play super fast arpeggios. Further, it's designed to be held in your hands in portrait mode, so you can quickly perform changes with your thumbs. Also, under the hood, all changes you make are quantized — allowing you to anticipate time by touching a parameter early, so the change happens at exactly the right time.

This is great, and works very well… However! It's always been a challenge to start the sequencer from not playing to playing. You could press the play button and just let it run, but if you wanted to control starting and stopping in a more expressive way (which I very much prefer!), it gets a bit more complicated. That first touch would always happen the moment you touched, but every other touch would be quantized. Subtle difference for sure, but definitely weird.

Ideally, what should happen is that all touches are quantized, even that first one. So that, when you stop and start playback, it starts quantized, just like the other touches.

So, something exciting… This is exactly how it works now! And it's all thanks to Ableton Link :]

Basically, at some point after releasing Arpeggionome Pro, I realized how I missed an opportunity to have dotted note lengths on the Performance Matrix — it launched with just halves and triplets.
Yes, I could have just updated the app… but since I try to be super strict about not changing UI after an application has been released, I just accepted it and moved on (see Fugue Machine and Link to MIDI).

However… now that I'm here and revisiting the project, I figured out a way rationalize adding it… by simply burying it in an optional setting. I think I'm ok with this :]

Ok ok, that was many words. Thanks so much for your support and interest over the years (over 4 now!) and please reach out if anything comes up.

The update arrives with a new demo video, but this requires a PHOTO SEIZURE WARNING!
