KV331 Audio is proud to announce the availability of their award winning software synthesizer SynthMaster 2.9 on iOS platform. As being the first app developed using KV331 Audio’s new cross-platform UI framework, SynthMaster 2 runs as a standalone app or AUv3 plugin on iPads with iOS 11 and above. SynthMaster 2 supports native resolutions of various iPad devices. User interfaces are provided for 9.7, 11 and 12.9 inch iPads in 4 different skins (Blue, White, Dark, Proto). Separate interfaces are provided for the AudioUnit plugin as well. SynthMaster 2 comes with 1000 factory presets designed by world class sound designers such as BigTone, Nori Ubukata, NatLife and Yuli Yolo. Thanks to the comprehensive preset browsing features, users can easily filter presets by author name, bank name, instrument type or preset name and find the sounds that they are looking for. There’s also an IAP Shop, which lets users purchase additional sounds: 1. "Desktop Presets Upgrade": This IAP adds all factory presets in SynthMaster 2.9, increasing the total preset count to 2000. 2. "All Expansions Bundle": This IAP adds all current 38 SynthMaster preset expansion banks. Sound Engine: At the heart of SynthMaster 2’s powerful sound engine lies its oscillators, modulators, and filters. Oscillators: The oscillators can operate in 4 different modes to generate sound: 1. In Basic mode, the oscillator plays single cycle waveforms or samples. With the Oscillator Unison turned on, up to 8 voices per oscillator can be played. 2. In Additive mode, 8 Basic oscillators can be stacked up to create richer tones. 3. In Wavetable mode, the oscillator can play wavetables with up to 256 frames. 4. In Vector mode, 4 Basic oscillators are mixed in 2 dimensions. Modulators: Modulators are simply basic oscillators that can be added to other oscillators or modulate other oscillators’ or modulators’ phases. By connecting modulators to other oscillators or modulators, complex FM tones can be synthesized. Importing Wave Files into SynthMaster: While designing sounds, users can easily import wave files into SynthMaster 2. SynthMaster 2 can categorize those files into waveforms, wavetables or multi samples and import them accordingly. Filters: Once the sound is generated by the oscillators it goes through SynthMaster’s filters, which can operate in 6 different categories: Digital, VAnalog, Ladder, Diode Ladder, State Variable and Bite. Custom distortion can be applied before or after the filters as well. Modulation Architecture: SynthMaster 2 features a comprehensive modulation architecture with a wide range of modulation sources: 1. MIDI controls 2. Macros controls 3. 4 ADSR envelopes per layer 4. 4 Multisegmented envelopes per payer 5. 4 LFOs per layer 6. 4 Sequencers per layer 7. 4 Keyscalers per layer There’s real-time visual feedback that lets users see how modulation sources and targets are changing when a note is being played. This is extremely helpful when designing sounds with SynthMaster 2. New modulations can be created easily by dragging and dropping a modulation source onto a knob or slider control. Users can easily see which controls are modulated by a modulation source by clicking on that source. Controls that are being modulated by that source will display modulation amounts. By long pressing a control, the modulation amount can be edited without the need to go through the mod matrix. Arp/Sequencer: SynthMaster features a comprehensive arpeggiator / sequencer with 32 steps. Users can easily create sequences by recording steps one by one. Effects: Each of the 2 layers in SynthMaster has 5 insert effect slots. 13 different types of effects can be instantiated in any of those slots. There are also 2 global effect send busses which can be used to create more complex effect routings. }

Hands down the most comprehensive synth app around. They cover any and every genre. You can either shop through the expansions to match your tastes, or just buy the affordable bundles and browse through those great presets to your hearts content.

La calidad de los presets cuidadosamente diseñados es excepcional, con efectos de modulación y aftertouch predefinidos aparte de 6 knobs y 2 pads XY predefinidos también para cada preset. Ya he preseleccionado más de 100 favoritos y apenas he explorado la mitad de los presets, antes de comprar ningún pack adicional (IAP). Me gustaría poder decir que tengo tantos presets favoritos en otros muchos sintetizadores que he comprado. Sencillamente, Synthmaster 2 está a otro nivel, aunque manteniendo una sencillez de uso digna de alabar. El mejor Sintetizador y más completo para iPad. Ahora mismo es imprescindible para mí en iPad. He gastado mucho dinero en sintetizadores para iPad incluso Logic Pro, pero nada iguala a Synthmaster 2. Espero ansioso a la próxima salida de Synthmaster 3.

Eigentlich ein toller Synth aber die Auswahl der Modulationsquellen oder auch Ziele in der Modmatrix funktioniert bei mir (11Zoll iPad Pro 3.Generation) nicht richtig: Es wird ein anderer Parameter ausgewählt als angewählt wurde. Die macht eigene Soundprogrammierung leider fast unmöglich, der Fehler besteht seit einigen Jahren… da ist dann geschenkt fast zu teuer..

Firstly this a super powerful and awesome synth. The way presets are saved along with info is broken. You can try save a preset after adding your Author and Bank name into the Info panel but the information upon double checking is gone. Even deleting presets from the save panel does not work. Half time info is saved and the other half of the time this essential process is corrupt. I know what I’m doing, but the app is very buggy in this regard. A shame really since this lets down a solid and essential synth . I hear the plan is to eventually release SM3 on iOS and the presets from SM2 should be able to load into SM3. But sadly the presets system in SM2 has not been fixed and still corrupt after several years. The last update 5 months ago did nothing to fix the issues. Please fix asap Bulent. I know you are busy ironing out any issues with SM3 on desktop, but SM2 really needs a stable preset saving/deleting/info naming fix.

Experiencing stuck "presets" with Synthmaster. I'll be scrolling through ones made, or the full bundle, and the screen will flash off momentarily and it will go back to the first preset I started browsing with. This is in Loopy, Drambo, AUM Etc. Dropped quite a bit for the bundle and because of the issue quit using the app

Thank you KVR331 team, the preset selection is now back to its normal fast response. 16th Dec. The latest iOS18 update has rendered this app unusable if you want to use MIDI Program Change or just manual selection…..be prepared to wait up to 1 minute for the change to happen! No response from the KVR331 support even after numerous bug reports and forum requests to fix this issue.
