Kreuzberg Audio is a Berlin-based company founded by Frank Hahn.
Frank Hahn is a very popular and well-respected name in the German drum-and-bass scene, and has been for over two decades.
Frank has helped develop hardware/software for industry-leading brands like inMusic and Korg, and, as an artist, goes by the name Giana Brotherz.
All of that combined experience led to the launch of Kreuzberg Audio and the tagline “Tools by producers, for producers.”
As a side note, Kreuzberg is a very cool district in Berlin, and is worth checking out if you find yourself in the city.
Reecer is aimed at producers of modern electronic music, including drum and bass, house, trance, dubstep, and techno.
Reecer has a three-oscillator architecture: oscillators A and B and a sub-oscillator.
Oscillators A and B each offer fourteen waveforms, including all the usual suspects, plus Format synthesis, Phase Distortion waveforms (classic Casio CZ sounds), and more.
The synth also boasts 29 filters, including vintage emulations such as the Moog Ladder filter, Korg MS-20, Steiner Parker, and the Oberheim SEM state-variable filter.
A decent chunk of Reecer’s multi-page interface is dedicated to movement, boasting a 16-slot modulation matrix with five LFOs and a Morph EQ.
The mod matrix features over 50 modulation targets and color-coded visual feedback to keep track of complex patches.
The Morph EQ also provides real-time visualization for movement in the spectrum.
You also get a distortion chain with fifteen distortion algorithms and four modules, which you can arrange in serial or parallel.
In addition to the Distortion page, Reecer provides an Effects section with Reverb, Compression, Delay, Modulation, and two independent frequency shifters.
Some of the more unexpected features are performance and composition tools.
Reecer has a Note-Splitter that transforms single MIDI notes into chords with up to seven voices, and a Performance page with macro controllers and an X/Y pad.
You can set Reecer up for a specific set/gig, and take it that little bit closer to a hardware synth with your MIDI controller.
The Composing page features various collections of bass, melody, and arp patterns.
As a debut soft synth, Reecer is both fairly comprehensive and impressive.
Check it out, and submit your presets for the chance to get a free copy of the final version.
