Ondes is an extraordinarily fun and expressive musical instrument for iPad.
• 2014 Best iOS Instrument - Sonic Joy Awards •
• 9.0 / 10 - Apptronica Magazine Review •

Inspired by early electronic instruments such as the Ondes Martenot and the Theremin, Ondes emulates the fluid playing style of those classic instruments with an interface and synthesis engine firmly grounded in the present day.

Whether you’re gliding through melodies & chord changes or creating dense polyphonic sci-fi soundscapes, Ondes is an instrument unlike any you’ve played before.

Recommended for use with headphones or external speakers.

Ondes is the latest music app from Olympia Noise Co., developer of App Store Editor's Choice* Chordion.

•••• Expressive Playing Surface ••••

Slide freely between notes, Ondes doesn’t limit you to the keys on a keyboard.

Adjustable note snapping for ultimate flexibility in playing style and ease of use.

Use the hold function to sustain notes while you take an epic solo on top.

Vertical movement can be mapped to volume and synthesizer parameters, adding dynamic possibilities to your music.

More polyphony than you have fingers!

Adjustable keyboard range and size.

Guidelines help you play in key. Choose from common scale types in any key or create your own.

Alternate tuning systems let you explore the world of microtonal sound!

•••• Unique Synthesis Engine ••••

Morphing wavetable oscillator with five wavetable sets.

Swarm oscillators! Two extra oscillators can be detuned and lag behind to create new textures.

Wavetable modulation sources include Y-Axis, sine wave, noise, circle, and ADSR envelope.

Resonant low pass filter.

Filter modulation sources include ADSR envelope, sine wave, and Y-axis.

Amplifier section with master volume, Y-axis control, and ADSR envelope.

Y-axis can be mapped to control the rate and depth of wavetable and filter LFOs.

•••• Effects ••••

Large selection of reverb types with adjustable amount.

Delay effect adjustable level, feedback, time and filter.

•••• MIDI ••••

Use Ondes as a MIDI controller to control your favorite software and hardware synths. Ondes isn’t like other controllers though, so read the instructions to learn about how to get the best results.

•••• Inter-App Audio ••••

Record directly to Garageband and other audio apps on your iPad using Inter-App Audio or Audiobus.

Built-in Inter-App Audio transport allows you to control a host app’s play, record, and rewind buttons.

Supports Audiobus State Saving.

•••• Beautiful Design ••••
Visualization of synthesis parameters makes for fun and intuitive editing of parameters.

Clutter free screen lets you focus on making music.


Built-in Manual makes it easy to dig in and learn about Ondes’ features.

What's new in version 1.1

What’s new in Ondes version 1.1? A lot!

Two extra oscillators to thicken your sound. Detune them and tell them lag behind to create a swarm effect.

Press the ‘hold’ button to sustain notes indefinitely. Play melodies over top or move the sustained notes around.

You asked for it… You can now control other synths and electronic instruments with Ondes using MIDI. Please read the instructions though — there are a few things you should know about first!

The Y Axis can now control more parameters:
Assign the Y Axis to control wavetable LFO rate & depth.
Assign the Y Axis to control filter LFO rate & depth.
Adjust the Y Axis to control volume from -100% to 100%

Using Ondes as an instrument in Garageband or other DAW just got easier! You can you control the play, record, and rewind buttons from right inside Ondes.

Choose between small (1.5 octave) and large (2.5 octave) range for the keyboard.

New “Scale” and “Chromatic” snapping modes.

In the mood for some modes? How about the “prometheus” scale? Choose from a bunch of pre-loaded scales or create your own. Save and reuse your custom scale types!

Put all that microtonal space to good use with alternate tuning systems. Choose from experimental and traditional tuning systems such as Just Intonation, Pythagorean, and Highland Bagpipe tuning. Create your own tunings or import & export .scala files. (Some limitations apply)

Ever feel like A440 isn’t right for you? How about A415? That’s more like it.

Get the bundle. I love this and for under a tenner must have. The other app in the bundle is really good too.
