Heartburn is an "additive-subtractive" soft synth which has a few interesting variations on the classic virtual analog synth structure.

Structurally, Heartburn consists of 3 wavetable oscillators plus an external input channel, feeding into two filters, one a simple low-pass/high-pass/band-pass/band-stop type, one a more sophisticated formant filter capable of creating vowel- like sounds.

Normally the three oscillators and the external input each have an amplitude envelope applied and are mixed to get the "dry" output. Optionally, the external input can multiply (ring modulate) oscillator A instead of mixing, and oscillator A can multiply oscillator B.

Normally, the dry output is fed in parallel to the simple filter and the formant filter, then the dry and both filter outputs are mixed to get the final output. Alternately, the filters can be cascaded serially, with the output of the simple filter forming the input of the formant filter, and this combined signal is mixed with the dry signal.

Three separate envelope/LFO generators are provided; unlike the traditional ADSR envelope, they don't have a concept of "sustain level", but instead they have a "loop time". Each component which can be modulated by these envelope generators has, in effect, two "sustain levels" which are ramped between over the loop time period. In the case of oscillator amplitude, this provides tremolo (oscillation between sustain level and sustain+tremolo level); in the case of oscillator frequency this provides vibrato (oscillation between basic tuning and basic+vibrato tuning), and finally in the case of the filter components, filter sweeps and "vowel movements". Any envelope generator can be selected for any of nine envelope targets.

The mutation feature allows you to rapidly experiment with patch variations. When the mutation rate is set above "none", the parameters of the synth are randomised as each note is triggered. Several different mutation rates are available; at or below the "Chernobyl" level, the critical parameters of "coarse tuning", oscillator inter-modulation, and filter topology won't be modified at all. You can set the mutation rate high to hear wildly different sounds on each note; once you find something interesting you can reduce the mutation rate to explore nearby variations. It's possible to come up with some interesting patches just by using the mutation feature and not manually modifying parameters at all.

i agree with the previous review 100%; that this is a very twisted synth and very underrated. this synth has a very wide range of sounds not just harsh but it is capable of your everyday basses and leads. the mutate feature is one of the best things i have seen on a vsti ever.

the new teaser presets are good and im deffinatly going to buy the full version when it come out.

my only problem with this synth was the gui; i found it a bit bunched together and bland. the way this things sound it should have a bright green color scheme with toxic barrels spilling in the back ground and monsters creeping.

can run alittel cpu hungry at times..

tiny god is very good with their customer support; i have asked them many questions and have alwys recieved a promt reply.

if your looking for sounds that are a bit out the ordinary DL this NOW!Read more

Here on K-v-R posters constantly praise products as "sick" and "twisted," yet this--the sickest and most twisted synth of all--has (until now) yet to be reviewed! Come on guys and gals, put your money where your mouth is! Russell Borogove has created the most interesting VSTi out there, and at 25 bucks it's a total steal. The original presets are pretty good, and the new presets by Ben Crosland are extremely inventive (more by Ben are promised). The synth's interface is a little cluttered, but it gets the job done. And the flexibility is amazing. This thing is capable of an amazing array of sounds. The coolest thing is the randomize and morph features, which allow the user to create utterly original sounds at the click of a mouse. This isn't just a VSTi--it's almost a work of art unto itself.Read more
