INTRODUCTION

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.

### 3/5 — keinplan geht nicht mehr

*2026-05-08*

? ? ? funktioniert nicht mehr hab Musik damit gemacht. Jetzt mit einmal funktioniert die App nicht mehr restore funktioniert auch nicht soll mich anmelden aber kein Plan wie warum werden Dinge kompliziert, die vorher nie kompliziert waren?

### 1/5 — Was my go to synth

*2026-04-17, version 1.1.27*

Completely useless  now. I have been using this for many years as the sounds are top notch but now it’s useless. Standalone app won’t load my purchases and wont even respond in my DAW software, all of them. I’ve messaged about the problem and had” we will look into this”. After weeks nothing. I even spend a grand on the latest iPad Pro M5 thinking it would sort the problem but no. I have hundreds of songs that rely on this app and now they are unusable without months of rework. Two years ago I would have given 5 stars but now not even worth one as it doesn’t work. Sorry for the negativity but I’m one very upset customer.

### 1/5 — Assurdo

*2025-10-18, version 1.1.27*

Mi sono registrato, ho pagato 5.99 euro per registrare un brano e non registra … chiede ancora 5.99…

### 3/5 — Program Change doesn’t work

*2025-01-02, version 1.1.27*

I have been trying to change the sounds via program change, but I haven’t been able to. I could only change them using the “midi learn” feature, but I need to go directly to the program instead of going through other programs.

### 1/5 — Privacy

*2024-12-17*

Für was Kontaktdaten ziehen? Als ich die App gekauft habe war das nicht.

### 3/5 — Help

Sont muets 
Faites quelque chose
