Get KQ Dixie 26 instead. ### If you bought this app recently, you can request a refund. KQ Dixie is a 6-Operator FM synthesizer that is modeled on the synthesizer which appeared on the 1980s. FM synthesizers make sounds with Frequency Modulation. FM brings rich and brilliant sounds which are impossible to create with analog one. It makes very complex waves with simple modulations. The same method is used for radios. The synthesizer gained much popularity in the 1980s. This app lets you make sounds freely with 156 voice parameters. Almost all parameters but multi-timbral, filter, and delay are compatible with DX7. Audio Unit v3 compatible. Multiple-Out is supported when you use "KQ Dixie Multi". Audiobus compatible. Inter-App Audio compatible. 32 algorithms included. You can manage the hardware DX7 when it is connected with external MIDI cables. Supports DX7 System Exclusive Messages (SysEx) and syx files. Supports Zip files. Place Zip files at the app folder instead of extracting them. Supports micro tuning. The app can load Anamark/Scala tuning files (TUN/SCL). Supports external and virtual MIDI. Supports Volca FM. You may be able to find a lot of patches on the internet. Multi-timbres and Unisons functions are there. Yamaha DX7 is a trademark of Yamaha Corporation. Volca is a trademark of Korg Inc. I have no business relations with Yamaha and Korg.

I can use Sunvox or Picotracker to drive this synth via MIDI ### 5/5 — Perfect App Perfect support! *2025-05-13* I'm old enough to have had the original. Dixie took all my old sounds sent via sysex from my DX7II and sounds 1 to 1 the same. When I had a small issue the Dev responded, solved the problem and reposted an update within hours! Why anyone would want an original DX7 when this exists I've no idea. Who wants to buy mine? ### 5/5 — Powerful instrument with multi timbres! *2025-05-05* If you dig into the timbre and hook MIDI into envelope and the timbre and channels it become crazy poweful!!! ### 5/5 — My First FM App *2025-03-27* I really like it! ### 5/5 — This is the one… *2025-01-21, version 4.0.3* …if you gotta have that DX7 noise. ### 5/5 — Awesome! *2025-01-05* Access to thousands of FM patches with full editing capabilities. One of the best music apps on iOS. ### 5/5 — Random Mode *2025-01-04* Please, add a Random Mode in the next Update ### 5/5 — とても良いアプリです! *2024-12-19, version 3.4.13* 私はこのアプリがとても好きです。JR東日本や他の多くの鉄道会社が使用している機器をエミュレートすることができます！ ### 5/5 — Legendary App from Legendary Dev *2024-12-15* Still the best tool for creating DX7/Volca FM hardware patches. The sounds translate very well to either FM or FM2. Great work. ### 5/5 — The best dx7 simulator out there *2024-11-03* So many features in an app you could want.
