Arturia iMini Review + Demo [Video]

Arturia, iMini, Minimoog, iPad, synth

When Arturia first released iMini, it was already quite impressive. To have a faithful, rich sounding Minimoog emulation running on your iPad for just $9.99 should have been a miracle for most. But of course, it is just our over-priveledged nature to hold an amazing human achievement in our hands and still cry about what it lacks. No Audiobus? Wahhh!!!

Arturia was quick to respond to this oversight, adding the inter-app audio capability in version 1.1, along with a few other bells and whistles. Now, there is truly no reason to complain. You can plug iMini into Audiobus, you can even plug external audio INTO iMini for God’s sake! And that’s not all:

“background audio advances mean that iMini is always live, yet will still respond to MIDI and be able to run its arpeggiator when working as a background app. And on that very note, whenever iMini is making no sound itself its CPU usage drops dramatically — another neat touch that helps keep things running smoothly when running multiple music apps.

Moving onwards and upwards, expanded MIDI support lets those up-to-date iMini users pick and choose from multiple sources; moreover, inter-app MIDI support — which establishes MIDI messages that enable two iOS devices to identify and enumerate each other — makes it much easier for cool controller apps like Audanika’s SoundPrism Pro advanced MIDI controller for iOS to individually control multiple iMini instances while running in the background on the same iPad, for instance. Let’s talk, in other words!” – Arturia

Yeah yeah, that’s all well and good, but what ELSE does iMini do, you say? Let’s take a more in depth look…

iMini has three tabs: Main, Perform, and FX. In the Main tab, you see a wood-panel framed, familiar synth layout. Choose from a large library of sorted presets, tune it up or down 2 octaves, set the Glide (Portamento) amount, adjust the Mod-Mix (between Osc.3 & Noise), and you’re off to the races.

The Oscillator Bank contains three oscillators, each of which can be tuned over several octaves. If you hold your finger on oscillators 2 or 3, further coarse tuning is revealed. You can also choose a separate waveform for each, from triangle, saw-triangle, sawtooth, square, wide rectangle, or narrow rectangle. Set their volumes in the Mixer section, along with Noise and External Input. The Modifiers section offers a tasty 24db per octave filter, with Cut-off, Emphasis (Resonance), and a Contour setting that controls how the filter responds to the Envelope Generator. There is also a Loudness Contour with amplitude envelope controls. In the Output section, you set the main level, volumes for the Chorus & Delay effects, or switch to Polyphonic mode.

The Keyboard is pretty straight forward with pitch bend and modulation wheels. But that’s not all: if you hold down the small settings icon next to the iMini logo, you get some additional controls, including the ability to change the octave, scale, and key.

The Perform tab is really where the action is. Here, you have the Arpeggiator and two XY pads. Get that sound throbbing, then give it the two-finger attack tweak. The default filter and contour controls are pretty fun, but you can set any of the controls from the Main page to the XY axis. Add a little Chorus and or Delay in the FX tab to fatten up your sound.

IF THAT IS STILL NOT ENOUGH FOR YOU, go ahead and fire up Audiobus, add some effects from your favorite app, and record that ish! While the sound of iMini is pretty rich and warm, I like to run my keyboards through guitar pedals, so the free GuitarTone app from Sonoma does the trick for me, (although it is a bit buggy with Audiobus on my iPad 2). Loopy HD, another invaluable offering from Audiobus’ maker A Tasty Pixel, is a cool way to lay down ideas on the fly and let them loop on top of each other ’til you’re dizzy.

Here’s a video of me making some noise with these toys:

“With all this talk of added support, it’s good to know that Arturia will make a donation to The Bob Moog Foundation for every iMini sold in recognition of the groundbreaking instrument to which it owes its very existence. In turn, this supports the dream of building the MoogseumTM (Bob Moog Museum), the convergence of The Bob Moog Foundation’s goals of inspiring and educating people through electronic music.” –

Audiobus Author Releases SDK & Amazing Audio Engine

Since its release 3 months ago, over 100 music apps have joined the quickly growing Audiobus community (including the just announced Garageband). Now, that list is set to expand exponentially. Michael Tyson, Audiobus creator, has unveiled two surprises on the iOS music world. The first is The Amazing Audio Engine:

The Amazing Audio Engine is a sophisticated framework for iOS audio applications, built so you don’t have to.

It is designed to be very easy to work with, and handles all of the intricacies of iOS audio on your behalf.

Built upon the efficient and low-latency Core Audio Remote IO system, and written by one of the pioneers of iOS audio development and developer of Audiobus Michael Tyson, The Amazing Audio Engine lets you get to work on making your app great instead of reinventing the wheel.

The Amazing Audio Engine is the code on which Audiobus, Loopy, and Loopy HD were built. It includes Audiobus support (natch) and is free to download.

Also completely open-source is the Audiobus SDK. This makes it a breeze for developers to implement Audiobus support for their app. The Audiobus Developer Center is at http://developer.audiob.us

You’ll find extensive documentation, a developer community forum, and utilities to register and manage your apps so that they appear within the Audiobus app and on our site

These are some seriously great developments for audio app programmers (especially aspiring ones such as myself). The world of iOS inter-app audio is growing up fast! Onward!
