Beast of a Soft Synth

Ready for a beast of a soft synth? KV331 Audio's SynthMaster does it all: Virtual Analog, Additive, Wavetable, Wavescanning, Phase Modulation, Frequency Modulation, Pulse Width Modulation, Ring Modulation, Amplitude Modulation, Physical Modeling, and SFZ Sample Playback synthesis. Factor in its dual layers, multi-mode oscillators, analog modeled and digital filters, flexible effects routing with 11 types of studio-grade effects, massive modulation architecture with 95 modulation sources and over 650 targets, and gentle pricetag, and you've got your new go-to software synthesizer. KV331 Audio calls the SynthMaster semi-modular. Here at Sweetwater, we call it amazing!

KV331 Audio SynthMaster at a Glance:
  • Semi-modular architecture
  • Extensive mod matrix
Semi-modular architecture

KV331 Audio SynthMaster is semi-modular, which means you be up and running with killer sounds instantly, but you can also patch up anything you can dream up. The architecture is brilliant. For each instance of KV331 Audio SynthMaster, you've got two layers, followed by two global effects send busses. Each layer sports dual oscillators, an arpeggiator, four modulators, two filters, four ASDR envelopes, two multistage envelopes, two 2D envelopes, two LFOs, and four keyscalers. Using the modulators, you can modulate frequency, phase, amplitude, or pulse width of the oscillators or any other modulators at audio rate.

Extensive mod matrix

The KV331 Audio SynthMaster gives you a massive modulation matrix with more over 650 modulation targets and 95 sources you can plug into 64 available slots. This includes ADSR Envelopes, 2D Envelopes, Multistage Envelopes, LFOs, KeyScalers, Easy Parameters, Vocoder Bands, MIDI Velocity, Aftertouch, Pitch Bend, and MIDI CC. If that's not enough, you can specify up to three modulation sources for each modulation target. The modulation matrix also features visual filtering, which lets you filter - and see on the user interface - targets for a specific source (and vice versa).

  • Comb filters - digital filters used in physical modeling synthesis
  • A distortion stage can be inserted before, after, or even inside the filters
  • 11 different effect types (with flexible effects routing):
    • Distortion, LoFi, Ensemble, Phaser, 6-band EQ

My new soft synth favorite!

The name of this synth always sounded kind of cheesy and it might have been the reason (not very logical, I agree) for me not paying too much attention to it. Nevertheless during the Black Friday sale I finally pulled the trigger and got me one of these from Sweetwater together with Obscurium by Sugar Bytes and couple from AIR. And in all seriousness, I'm REALLY glad I did.
After less than two weeks playing around with Synthmaster 2 it quickly began my new "go to" synth that I favor over practically all of my other soft synths that I currently own. And I barely scratched the surface of the SM2 potential.
To my ear SM2 sounds like it was designed for exactly my style of music. Nearly every sound is of truly excellent sonic quality. In all honesty I must say that I simply love Synthmster 2 and today I'm going to buy all of their currently available soundbanks since they are on the year's biggest sale costing only five bucks each! A total no-brainer I would say.
I can't wait for the guys from KV331 to release their Synthmaster 3. Hopefully sometimes next year, in 2023. Because I just became their customer for life!

Awesome

First, I had no clue what a synthesizer is or does before my purchase. The sweetwater folks have been extremely helpful and knowledgeable. A couple of discoveries that i didn't see in the documentation are

1) This CAN BE a plug in OR standalone. In my case I connected to my Alesis Recital with a USB A cable and "alesis recital" appeared on the edit / I/O drop-down to be selected. Then i just played the keyboard and listened to the modified sounds on my PC speakers. Sweet!!

2) The synthmaster can simply play notes from the keyboard with applied changes AND it can create new sounds to play when a keyboard key is played. The Player only applies sounds that already exist.

3) Although my "experiments" changed default controls and I couldn't remember what they had been, reinstalling by running the install application works as a factory reset and takes about a minute. I may find an actual "return to defaults" control as I play with this.

…at Sweetwater for both synth and player made this a must have and I've been having a blast hearing what this thing can do. TONS of presets and a sleek interface... I love it.
