Features & Capabilities

iM1 v1.2.0 brings the classic M1 experience to iPad and iPhone, faithfully reproducing the original PCM data and circuit-inspired sound.

The Smart Sound Browser makes it easy to find sounds, including the Best of M1 and M1EX libraries.

Designed for on-the-go production, iM1 works as a sound module with Gadget, Audiobus, and Inter-App Audio, and can connect to a USB MIDI keyboard as a standalone instrument. Sounds created in iM1 can be shared with the KORG Legacy Collection. It was selected as App Store Best of 2015 and has topped the Top Paid Music charts in many countries.

User Reviews

Users broadly praise iM1 for its authentic M1 sound and efficient AUv3-based operation on iPad/iPhone, with strong value. However, recurring complaints center on cross-DAW compatibility (GarageBand, Logic Pro, Beat Maker 3) and AUv3-specific limitations (not all patches, preset saving in AU hosts issues). Other common notes include a non-working sustain pedal, UI size constraints, and requests for usability tweaks (double-tap reset).

Pros

Authentic reproduction of the classic Korg M1 sounds.
AUv3 support and universal availability on iPad and iPhone.
Low CPU usage that allows multiple instances without heavy load.
Rich, versatile sound library with both vintage and modern tones.
Strong value for money and portability for mobile production.

Cons

Cross-DAW compatibility issues (GarageBand, Logic Pro, Beat Maker 3) and IAA deprecation.
AUv3 limitations (not all original patches exposed; chords/keys/KAO pad not in AUv3).
Preset saving in AU hosts (e.g., AUM) can fail or be inconsistent.
Sustain pedal does not function in some setups.
UI/UX constraints (small square interface) and requests for easier value resetting (e.g., double-tap to reset).

Better than the actual m1

by Bl*****, 2026-06-12

I love classic synthesizers and being able to noodle around with hundreds of M1 patches to my hearts content for the cost of a trip to a burger joint is awesome. I use it inside iMPC Pro and it works great.
