BUILD QUALITY
Feels sturdy yet light, fairly solid plastic chassis. Keybed feels very similar to Microkorg, in other words it's average at best. The knobs feel very solid..no wobble, and they have just the right amount of resistance. Patchpoints feel kind of sticky/mushy, never encountered this in other semimodular gear, so I can't say if it's good or bad. Joystick feels very cheap like it will brake if you're not careful..it's this very very light feeling plastic. Oscillators are fairly stable.
USER INTERFACE
The UI is well laid out, and it has legends printed below patchpoints to show the default signal path when no patchcable is connected. Even the synth is very small, I'd say even the person with large hands should have enough space to comfortably operate the patchcables and knobs. There are 5 short patchcables included, so I highly recommend you buy more (few 50 cm as well). I was pleasently surprised to notice, that the OSC-waveform buttons add/remove a shape, instead of choosing just a one waveform to be used at a time. Another interesting solution for a modular-newbee like me was, that you use FM1 as an filter envelope depth parameter.
SOUND
Tricky thing to descripe the sonic character of this one. Only other dual VCO synth I have to compare this with, is the Behringer Neutron. The Neutron sounds silky smooth compared to this..kind of like comparing a Moog with SH-101 or similar. The Malevolent feels almost like it has a mind of it own; it's dirty, glitchy, angry, cold..full of those kind of sweetpots, so even one millimeter of a knob turn can make a huge difference in sound. Most often I feel that twisting a knob between 7-12 o'clock results in adding saturation, and beyond that it quickly goes in to extremes. Think of the typical un-clinical sound of a VCO and multiply it by 5. S/R-ratio is poor though; even with oscillators' volume a at zero, there is a noticable noise (white noise) when playing a note. The filter is full of this sharp "burbliness" if you will, kind of inpossible to tame anything with it..like the lowpass filter..it just rather muddies the sound when used to extremes rather than removes higher frequencies if that makes sense. You can make some basic leads, basses, etc, but it's almost inpossible to make them sound smooth..this isn't the synth for those sounds. In my opinion the Malevolent feels at home for industrial noise, horror soundscapes, aggressive punk/rave, experimental modular type of soundscapes.
