I got this during a super sale which made it hard to resist. Normally I don't like relying on a sequencer but this one has some cool features. 49.99 seemed hard to pass up. I had been curious just based on how easy they make micro editing and chopping up drum sequences. It hasn't kept me from using Battery4 or the like in most productions but it has helped a lot in different areas than I expected originally. I use it a lot to get a flow or beat going. I use it in tandem with B4 a lot. Plus, you get some really great samples out of it too.
I thought I'd take advantage of an '80% off' deal on Breaktweaker. I'd downloaded the demo and thought it looked interesting, but it's way overpriced at its usual asking fee for 200 dollars or so.
Basically, it's a drum machine and sequencer with some nice features. You get six lanes, one for each sound. There's a large sample library of 'standard' drum sounds (the usual suspects, 909-y kicks and snares, some dubsteppy things). You've got fine control over individual steps in the sequence - samples can re-pitched, distorted, filtered and so on. Additionally - and most innovatively, the individual steps can be micro-edited to a ridiculous degree. The sample is cut up into tiny granular chunks, and the individual chunks can be reordered in a variety of ways to give stutters or pitched sounds. So it's like 'step granular' synthesis. Additionally, each lane of sounds can have a different number of steps - so one lane might be 16 steps, another 5, and so on, which is good for creating unusual polyrhythms. The transport speed of each individual lane can be different too.
It's not just samples though - each lane has a synthesizer option. LFOs can be assigned to a wavetable, and so interesting blippy or Buchla-esque sequences can be built by putting a different note on each line. Synths and samples can be mixed within the lane too.
There are some problems though. It's a MIDI-triggered instrument. There is a free-flowing preview option, but it would have been nice to have a 'copy pattern to track' option, as the MIDI triggering depends upon your fingers (yes, you can quantise it afterwards; the idea is like Stutter edit, where you build loads of patterns, one on each key of your controller, and jam with them in real-time).
And it's a CPU hog. If there's too much going on, it will cause audio dropouts quite quickly.
Having said that, this is a lovely plug in for creating glitchy or quirky loops quickly. If it was just a bit cheaper, it would be better, though.
