This is one incredible idea that is credibly built and features a great, easy to work with interface. This is the kind of ensemble you'd want Reaktor to do but it doesn't have the filters for them nor the excellent user interface.
In terms of sounds, there's not much you can't do with BeatBurner other than going for ambient soundscapes. You can get execptional ambient sounds, but not the kind used as most musicians use it. Still, if you want throbbing bases, massive drum parts, a predictable, self-controlled bass and drum setup or threatening to eerie ambiences.
It all depends on what you use as a sample to get things started. Based on the 300+ mb sample library of drums and bass patterns you'll get some of the nicest changes of pace in what drums sound like or what bass to lead tracks can work. It's a wonderful sound that trancends styles. Ask yourself if you like synths that evolve or do unique things that are different but still useful? If so, you need to consider BeatBurner as part of your music arsenal.
It has crashed a couple times out of 100 but in general is well behaved. The presets are good ideas of what can be done with BeatBurner, a Code Audio product distributed by G-Media. If you like experimenting in any way this is your beat oriented synth....and you don't have to use only use drum samples. Anything with a well defined pulse will do. The results are up to you although Greg from Code Audio suggested working with the balance of the sample vs the synthesized sound. It's great advice as some sounds will sound unexciting until you do some tweaking of the two, and that goes for each part of the synth. The synthesis engine is unique and will be somewhat detailed in discussion.
BeatBurner is essentially a sample playback synth that is optimized for drum loops. You load a sample which shows up in a lane. It runs and you can see the transients available to you. The track itself is set up so you can apply as much or none of the original signal to the synth sample which too can be as quiet or loud as you please.
The synthesis part of BeatBurner is simple but sophisticated. Below the sample display are pitch (broken into many tiny individual segments, similar more to something that can be easily worked from on the pitch to several octaves in either direction off and for short to as long as the sample sequence goes. Below is a multipart envelope that controls the filter and LFO. Visual tools like these make the number of controls more worthwhile of exploring than some programing phobic souls will learn to put up with.
The pitch controller graphical window allows you to create pitch slides, create modulations like moving the pitch wheel on a controller might if you were good at carefully moving it up and down.
There are two pre-filters, meaning the filters are first in the chain rather than down the signal flow which is typically where it would be found. The synth engine is actually a five band waveshaper, similar to a EQ but controlling the signal rather than effecting it. There are also a more traditional 4 control synth engine that controls decay, detune, glide and mix. Fully counter clockwise there's no sound, the further clockwise the more effect on the signal chain. There is also a simple but great sounding delay effect and flanger.
Each pre-filter is available with a linear control for either or degrees of both available. This is similar to many synths that use oscillator faders if that helps you get a handle on things.
Below that and paired to the multi-stage envelope are additional(!) multi-envelope filters. If you are familiar with filters you get an idea how sounds can quickly be changed into something very unique by working with them. If you don't it will take you less than a few minutes to figure out how to use them. Beyond this is a distortion algorithm that is quite good, from subtle to woofer shaking into a multiple envelope LFO that is simply deadly for basses and transmuting drums into secondary, drone like sounds or at other times like having a sub-oscillator. And at the end of the chain, in case we haven't had enough fun with filters there is a post-filter.
This is a simple design, in some ways a precursor to monolithic synths like Symptohm:Melohman and being part of the G-Media family it's not all that surprising the whole system sounds like a fantastic drum mega-filter VST. Yet it is the ability to go the extra few small steps that makes BeatBurner so interesting. It has a lot of use as a drum synth or a rhythmic synth, even a synth line generator.
Pros: read the beginning of this review if you need more pros. Cons: you need to save your stuff as it sometimes can crash. This may vary with computers. Verdict: if you make beats and want rhythmic things to work with, this is itn and at an attractive price. Don't think tweaking works? Try hitting the randomize button, not only do you get changes but they're almost always good sounding and on of the best things found in 04!
