CURiOS iOS Musikmagazin #17 – Musik produzieren am iPad


Von Rodrigo Roman
Gratis, iTunes
Funktion: MIDI-Sequencer


iTunes Beschreibung (Auszug):
sequencism is a music sketchbook tool that allows the creation of short and simple pieces of music. It is designed to provide a traditional user interface of track and piano roll editors, while taking advantage of the touch-screen capabilities of the iPad. It also includes other helper tools, such as chord helper tracks.

Note that the main goal of this app is to work as a sketchbook, thus it is not recommended to use sequencism to produce complex songs or to play songs live on stage.


• Simple track mixer and visual mixer (volume, pan)
• Multitrack editor: MIDI instrument tracks, chord helper tracks
• Support for SF2* and AUv3 instruments (*lightweight SF2 files only)
• AUv3 Effects
• Piano roll editor: add, move, copy notes within blocks
• MIDI keyboard, supports multiple scales, including user-defined scales
• Support for diatonic and chromatic chords
• Automatic transposing when changing chords or scales
• Supports Audiobus 3 and Ableton Link
• Support for MIDI keyboards, including Bluetooth keyboards
• Export to MIDI

AUv3 instruments requires iPad Mini 2, iPad 4 or newer.

Brusfri , AU

Von Klevgränd produkter AB
7,99 €, iTunes
59,99€ VST/ AU /AAX
Funktion: Rauschunterdrückungs-Plug-in


iTunes Beschreibung (Auszug):
IMPORTANT! Brusfri is currently AUv3 only, which means it won’t work in stand alone mode. It must be used as a Plug-in with GarageBand, Cubasis, Auria, AUM, AudioBus 3 (not AudioBus 2) or any AUv3 compatible host. If you’re not sure what AUv3 is, do not buy this app.

Brusfri* is a highly advanced audio noise reducer, packed into a simple and straight-forward interface. It is very well suited for cleaning up noisy audio recordings, while retaining sound quality. Unlike many other noise reducers on the market, Brusfri doesn’t mess with audio phasing to suppress noise (a technique that often comes with audible side effects). Instead, multiple fine-tuned gates are used to silence unwanted noise.

*Brusfri means „Noise free“ in Swedish.

CURiOS Kommmentar: Was die Software für das Geld leistet, ist jenseits von erstaunlich. Es vermindert zwar nur das Hintergrundgrauschen einer akustischen Aufnahme, darin wildert es aber in Qualitätsliga von Sonnox und iZotope.

Axon 2

Von Audio Damage, Inc.
4,49 €, iTunes
VST, AU, AAX $59
Funktion: Drum-Synth-Sequencer

Axon 2

iTunes Beschreibung (Auszug):

Axon 2 is a drum synth driven by artificial intelligence. (Well, „intelligence“ might be a strong word. Artificial something-or-other.) An experimental instrument, Axon uses a modified artificial neural network as a sequencer, and features seven FM-based percussion voices, that are really a single 18-operator FM voice.

If that sounds weird, you ain’t seen nothing yet. It is surprisingly intuitive once you get the knack of it, and is capable of all-new, complex rhythms that repeat in surprising ways. It often gets referenced as a „random sequence generator,“ but there is nothing random in Axon; it is entirely determinative.

The sequencer features seven „neurons“ that trigger a voice and send a pulse when they have received a predetermined number of pulses. You can wire the output of any neuron to the input of any other (with built-in loop detection to prevent runaway feedback), and in this manner pre-program the artificial neural network without having to go through a „learning“ phase.

The seven individual drum voices, each triggered by its attendant neuron, are 2-operator FM voices in a configuration to best make percussion sounds, with additional FM and AM busses that all voices send to and receive from. Each voice has a HPF, distortion circuit, and white noise generator to provide a full range of percussion-oriented voicing individually, while interacting with each other in new and unique ways.

Quantum Sequencer

6,99 €, iTunes
Funktion: MIDI-Sequencer

Quantum Sequencer

iTunes Beschreibung (Auszug):
Quantum is a performance midi sequencer which approaches music composition with an interactive creation processes – sometimes referred to as ’noodling‘.

Where pattern or piano-role sequencers are good for music forms (intro/verse/chorus etc) or grid entry, Quantum’s approach is built around the idea of a step being the focus – think of the step as a single note or chord written on a music sheet then add a lot of extra notation (like probability of playing or ornamentation say).

These highly detailed steps are then aligned into sequences (think melodies) that loop. You can have any length up to 64, but these can be further split into 4 sub-sequences that have their own set of sequencer parameters (like tempo, play direction, transpose etc).

To enter step parameters such as note pitch, velocity, gated length etc, 16 general faders are available which allow you to draw, drag, select copy/paste, inc/dec & link together to edit values. These are also midi learnable (midi cc or nrpn) to allow you to use control surfaces or midi controllers.

To aid you with faster control Quantum has loop actions which you can program in to carry out tasks when a sequence loops – e.g. transpose, randomise, start or load another sequence etc.

With up to 24 sequences playing Quantum introduces a mixer page allowing you to blend midi velocities. Built on the MidiSequencer engine, midi FX, devices & Controllers are now possible per sequence.

So why would Quantum be good for your setup? There are many midi enabled IOS & hardware synths that produce exotic timbres if you send them fast & varied midi controls that you just would not hear with keyboard playing or slow tempo tunes. Also, Quantum, embraces experimentation in melody creation and by copy/pasting allowing quick setup of arpeggios & counterpoint tunes that you can create & manipulate on the fly!

VirtualRoom AU

Von MN Signal Processing
5,49 €, iTunes
Funktion: Raumakustik-Plug-in

Virtual Room AU

iTunes Beschreibung (Auszug):
This application simulates the acoustics of a room and reproduces the sound signals for the two ears of a virtual listener inside the room. Listening to these signals using headphones gives the impression of being inside the room at the position of the listener. Please note that without headphones connected to your iOS device, this app may lead to unpleasant feedback noise.

When run for the first time, this application will install an Audio Unit v3 App Extension that can be used in various third party applications.

The sound sources take their signals from the left and right input channels (coming from a microphone, Inter-App Audio, or the AUv3 host application) and can be moved in real time by dragging the loudspeaker symbols on the screen. The listener can be moved by dragging the head symbol. Alternatively, sliders can be used to set the positions (including along the vertical Z dimension), as well as source gains and the listener azimuth.

The simulated acoustic environment can be chosen from three different rooms with different sizes.

Guitarscaper is a generative music app and virtual instrument that’s easy on the ears and fun to play. Launch the app, and with a single tap of the auto-play button, guitarscaper will create evolving and ambient guitar-based soundscapes that are unique every time.

While all of the guitarscaper sounds originated from a single electric guitar, many have been extensively processed to create an “impossible guitar” that can morph between orchestral-type swells and ethereal choir-like sounds. Think of it as guitar DNA taken to the next level!

Guitarscaper in auto-play mode is the perfect companion for relaxing, studying or providing non-intrusive headphone music at work or on your commute. You can even set a timer so you can fall asleep to its gentle and soothing tones.

You can also play guitarscaper as a virtual instrument using the dedicated keypads and performance loop recorders, and tailor the sounds with built-in reverb, delay and “character” effects parameters. And while you’re playing, guitarscaper can lend a hand by adding auto-accompaniment parts and even provides hints for notes it thinks might sound good depending on which notes you play!

    Hallo Markus, danke für die 17 Curios IOS Magazine. Ich weiß die viele Arbeit zu schätzen.
    Noch ein Tipp: In der Aufstellung fehlt ein
    exzellenter, kostenloser Synth.
    FM Player Classic DX Synths, erschienen am
    07.12. Ein must have.
    Freue mich auf die nächste Curios Ausgabe.
