KV331 Audio SynthMaster One Review & Preset Walkthrough

Hello there, back again with another cool article for you! This is going to be the last article of 2020! What a hectic year 🙂 This time I wanted to give you a bit of a different concept by featuring a virtual instrument/VST plugin: SynthMaster One by KV331 Audio!

KV331 Audio is a Turkish software company that I have been following since the mid-2000s. Back in the day, I was a fellow music/guitar forums user and did my best to learn from people who had similar interests on Turkish internet forums.

Even though I’m not a keyboard player or an electronic music producer, I always had a massive interest in music/audio production in the digital domain. For this reason, KV331 Audio got my attention when it was first released. However, during those days, I didn’t really have a computer system that can handle virtual instruments and plugins successfully so, to be honest, I didn’t have a lot of clue about it.

Recently, I have been investing in some gear such as new guitars, speakers and computer components to upgrade my laptop. My Victor G451 laptop with Intel i7 4710MQ processor was struggling in some cases such as loading multiple plugins and some guitar effect software (Guitar Rig, Amplitube…etc).

Upgrading RAM from 8GB to 16GB and updating graphic card drivers have really helped me obtain very low latency without any stuttering.

That’s why I wanted to give SynthMaster One a try so I have purchased a licence for myself! 🙂

SynthMaster One is an extremely easy-to-use wavetable soft synth. It can operate as a VSTi on both Windows and Mac and also as standalone software on Windows.

Here in this quick article, I wanted to introduce this wonderful piece of software to you and also provide you with a laid-back preset walkthrough.

I spent hours with SynthMaster One and picked up around 200 presets out of 1250 factory presets and played random stuff to show you its capabilities.

This demo video I made is about 1 hour long and please note that I did not intend to perform or dive into the crazy details that it has to offer. Just my favourite presets, so please click play below and listen to this excellent software synth!

I would also like to mention that I used the RME Babyface PRO USB audio interface (@48 samples) along with my Keith McMillen QuNexus MIDI Keyboard.

Even though I’m not an electronic music maker or producer, I listen to many genres, including electronic music ones. One of my favourite electronic music genres is probably psytrance or psyambiance.

I am a massive fan of Carbon Based Lifeforms and surprisingly when I was doing this demo video, I noticed a lot of similar sounds and textures with this type of music!
