SynthMaster Player for iOS received "2016 Editor's Choice Award" from Electronic Musician Magazine! SynthMaster desktop version is voted as "The Best VST/AU Synth Plugin" by MusicRadar readers and also received "Gear of the Year" award from MusicTech Magazine for "Best Software Instrument" category.

SynthMaster has received very positive reviews from acclaimed music technology magazines:

"SynthMaster: The most powerful softsynth you may not have heard of" Keyboard Magazine

"If ever there was a desert island synth, SynthMaster is it, covering all sonic bases with authority and a superb tone" Computer Music Magazine

SynthMaster Player for iOS is the MOBILE PLAYER VERSION of the award winning SynthMaster software synthesizer.
It is targeted towards users who prefer to use presets rather than designing their own sounds during music production. Although it is a preset based player, users can edit the following preset parameters:

1) 8 easy parameters assigned by the sound designer
2) 2 XY Pads assigned by the sound designer
3) Effect bypass states and send amounts
4) Layer bypass states and volumes
5) Master volume, polyphony

The free app comes with 100 factory presets. When users complete registration by entering their names and email addresses they receive another 100 factory presets as a bonus!

After completing registration, users can upgrade to the Pro version of the app by purchasing the "Factory Presets" bank via In-App-Purchase (IAP). With the Pro Upgrade all of the 800 factory presets are loaded and also the following features are unlocked:

1. Users can save the changes they have made to the presets.
2. Users can purchase additional preset banks via In-App-Purchase (IAP). We currently have 28 additional preset banks that contain 1750 presets for various genres/styles.
3. Existing SynthMaster users can download their previously purchased SynthMaster preset banks inside the app, so that they don't have to purchase them again.
4. Existing SynthMaster users can export their own presets in SynthMaster v2.x and import them into SynthMaster Player for iPad using iTunes.

Great but...buggy on latest iOS version

My previously purchased presets won’t download. There’s an error each time.

Edit: I found a work around. I kept exiting the app and purchasing the presets again (for free because the App Store has record of purchases). I had to keep exiting because after each purchase it asked me to download (instead of buy) my already purchased presets. Choosing the download option always had an error. For some reason it only downloaded when I pressed a buy button. Good thing it didn’t charge me though. I do love the app and presets.

It’s nice to control with iFretless as an MPE controller. It does get a little buggy at times when doing this though.

I haven’t contacted support though. I usually mess around long enough with things until I can get it to work.

Fantastic Sounds!!

I’ve had this app for a while now and bought several additional sound packs. The sounds that are made to sound just like those in songs we are all familiar with are amazing! There are so many presets it can feel overwhelming but in a good way. I’m running an iPad Pro 2020 and it has no problems running this incredible app.

I have a question though. If I buy SynthMaster One will the presets I’ve already bought as add-ones work in it? I really don’t want to buy them a second time. Thanks for this incredibly useful music app... I really love it!

Sounds good but...

Sounds great...but all kinds of problems when trying to install presets purchased for the desktop onto the iOS version. Entering the serial number from the desktop when registering is a crap shoot at best...most of the time you get an 'invalid serial number error'. When you are lucky enough for it to may or may not show purchased packs. And if it does you may or not be able to install them. When it does give you a 'download' link it does so only to tell you, once it's counted to 100% , that it failed. Sad thing is it sounds great but don't waste your money buying expansions.
