A port of Dexed, a FM Synthesizer. Features over 20,000 Cartridges with 32 patches each. Comes with AudioUnit AUv3 plugin for use inside AUM and other DAW apps like GarageBand. Get a camera kit and plug in a midi controller through USB, or get a 5-PIN DIN 1/in 1/out, to: USB and use the camera kit through USB MIDI Spec, NOTE: some devices handle SysEx differently and therefore we cannot promise support for SysEx, so invest in connectors and cables wisely. If you have questions involving making MIDI-USB work the best for your situation, email support. This iOS app was designed especially with small interfaces in mind. Example: an iPhone 5S or a resizable window inside AUM. If one clicks the menu eye, a feature LOCK SCROLL can be –very– important to set knobs, sliders, et cetera: if screen size is limited. LOCK PARAMs in the eye menu locks the parameters for scrolling without knocking loose the preset. In the CARTs menu double tap a cartridge to load a series of patches, the files will have a .syx extension. To use MIDI CC, in the menu eye you must first turn on MIDI CC. When MIDI CC is on it makes the tap events react like a right mouse button click. NOTE: MIDI CC, in eye menu, doesn't have to be on after CC controls are mapped. MIDI CC touch modifier will also turn off after you have successfully mapped a CC control, or when you delete the current mappings. You can turn it on again later to turn off mappings or create new CC mappings. I would suggest setting CC knobs in the bottom section of the screen – above keyboard (if visible). Currently you must save patch in DAW – for instance: GarageBand or AUM. Once we can determine unity and saving/loading between the AUv3 plugin and the StandAlone app, external save will be eventually developed. There is a pathway set to transfer .syx files through iTunes to the StandAlone app, only. Other plans include fixing pixelated images, a quick zoom to set CC mode and updating GUI to a higher degree, make sure midi CC knobs update.

What’s New

Version 1.0.75

UX changes, also verified that Midi CC works in Standalone and in AUM. The knobs do not update with the midi changes visually, but do audibly. That is a TODO. You can test by setting a Midi CC on Algorithm in the lower third of the synth. The algorithm plot window will change, but the knob won’t. Midi CC is more error-controlled now. Midi CC ON now locks scrolling and locks parameters and is meant for a single run. So if you want to map an other value, you will have to turn it on again.

Past updates: Zooming has been removed temporarily so you don't have to suffer with an unstable release until it's working. Please let me know of any errors as I now have a STABLE and DEVELOPMENT branch. Panning/scrolling is done with two touches now. LOCK PARAMs and LOCK SCROLL also now work again. You can scroll the CART .syx file browser with one touch, but may need to pan with two touches to the top of the CARTs file viewer. Knobs and sliders move with one touch. If you didn't get the master collection of 640,000+ patches, delete the app off the home screen and download from the App Store again. Knobs and sliders move with one touch. If you missed out on some previous versions there is a loading screen that should not be force quitted.

An fm synth with a huge patch library

The interface works fine on a 3rd generation iPad 12.9" and fills the whole screen in both landscape and portrait. It is pixilated and I hope the developer polishes it up.
It is great to have all the synth's settings displayed at once and only one other iOS app shows as much.
The most similar app is KQ Dixie which has a similarly complete but much less busy interface and is a much more polished app with a better keyboard. However, Dexed includes a huge patch library which KQ lacks. I have not had a chance to compare the sound of the two apps.
Hopefully, Dexed's developer Wil continue to improve it.

Love that the developer allows iPhone use

Dexed VST is amazing and I’m sure this runs well on an iPad. But since I don’t have a working iPad at the moment I love that the app is allowed to work on iPhone. Granted there’s a lot of scrolling around on a small screen but it’s better than not being permitted to run at all. I appreciate having the choice, as I’m sure others do too.

And it sounds great and has an unprecedented patch library for any iOS synth.

Excellent sound, UI glitches still present

The AU window only shows you a small portion of the controls on iPad Mini and 10.5 inch Pro. It appears that the developer tried to fix it with the last version. Currently, the only way to use the app is to load the AU in AUM, and orient the device vertically, then go back to horizontal, to access the other presets and preset banks. There is no Inter App Audio with which to record or add FX to the standalone app, which displays correctly. It's technically usable, and it sounds amazing. Hopefully it will work properly soon!
