iSEM is an amazing recreation of the legendary 1974 Oberheim SEM synthesizer expansion module. Known for its characteristic multimode filter and rich oscillators, the SEM is revered by many for its sonic power and flexibility.

Based on the TAE® technology found in our award-winning SEM V software, iSEM faithfully recreates this unique synthesizer and offers a level of sound quality that only Arturia can bring to the iPad®.

Unleashed Classic

Free all the potential of the legendary Oberheim SEM thanks to the Audio Unit Extension. In addition to being compatible with Audiobus and Inter-App Audio, iSem can now be launched directly in every Audio Unit host app such as GarageBand, offering you the same comfort and workflow as with a computer-based home studio. No more doubt is allowed, whether it is at home, on the road or on stage, with iSEM your iPad becomes the new core of your setup.

Expanding possibilities

We’ve added a few new features and some of the extra functionality that people have come to expect from Arturia products. Our 8-Voice Programmer allows you to mimic the polyphonic sounds of the classic 4- and 8-voice versions as well.

The Modulation matrix greatly expands the sonic capabilities of the original. And the effects page, performance page, Apple Inter-App connectivity, Core MIDI, AudioBus: all work together to make iSEM a supreme sonic workhorse and creative force multiplier.

ISEM is my perfect friend on the stage for my Ipad, really like it. its a very simple synth and straight forward, that is a feature i very like, i don't need to think i just touch the parameter i need. Simple tool, with good sound.

Having the 8 Voice Programmer in the iSEM makes owning an iPad worthwhile. Set up a few changes on each voice and put the Arpeggiator on and you have an amazing sounding early eighties bassline machine. The closest thing you can get to this is a real 8 voice which will run you over $10,000 and take half your studio up space wise.

As my iPad becomes more and more a mainstay of my studio setup, I'm especially impressed with the iSEM app. Besides boasting an incredible and unique array of patches, I LOVE the scale functionality and after touch scroll control on single keys! Looking forward to many hours of playing and programming iSEM on my travels around the world !

I have gained immense pleasure from experimenting with Arturia's iSEM for iPad. Being an owner of the original hardware synth, I can confirm that this virtual app stands up, providing a combination of complete familiarity combined with total stability, versatility, and the welcome addition of plenty of presets, plus extra pages and functions, such as the performance layer. An absorbing experience of real quality, I am thoroughly impressed and at a bargain price!
