ABOUT once upon a time Kilian Leonhard and the german keyboards forum users desiced to make a synth, ok the forum was only for ideas, in fact Kilian did all the work and the aim was to make a synth for 250€, the frist bath was made and sold, Kilian exploited himself ,so V2 was made and the price wnet up to still very ok level and the voice number raised to 5 Voices..

DETAILS 2 filters: one digital, one analog (series), env: lin + exp - Rozzbox is a one man small "company". it all started to make a nice digital synthesizer for about 250€ on microcontrollers/pic - to make it cheap and no need for DSPs or the like.. so the idea was to make "ROZZ" (rotz = german for.. uhm.. dirt..) todays music lives from the digital imperfection here.. so you can turn up digital dirt in a special section "rozz (rotz!)" and reduces bits and depth of calculating filters / aliasing is WANTED.. so, yes.. it is not an 8bit C64 synth, but it was designed for lofi sounds.. in fact the ROZZBOX ONE sounds much more hi-ended then one might think of. additional to this there is an analog filter available as an option. it has 3 OSCs feat. digital waves also and an LFO and 2 "mod matrix"-kind of routing sections. the filter is LPF or HPF with resonance, oscs range from 4 to 32". there is a small display for saving your sounds and there are of course 2 ADSR envelopes.

SOUND specialized on nasty and evil sounds, also LoFI.. but can sound nicer also..

VERSION update 2: - Analog filter (transistor based) on all new Rozzboxes (V2) - Envelope-Follower + Audio In (seperate Ins) - much faster ENV + Modulation - 2 (plus "Global LFO") instead of 1 LFO - 4 mod routings instead of 2 - 9 more mod routings - more mod sources - sequencer - more lofi FX

a little digital synth with wavetables and lots of "rozz" (digital artefacts that can be generated.. for nice musical digital noise)

todays music lives from the digital imperfection here.. so you can turn up digital dirt in a special section "rozz (rotz!)" and reduces bits and depth of calculating filters / aliasing is WANTED..

update 2:

- Analog filter (Transistor basiert/transistor based) ist serienmässig / on all new Rozzboxes (V2)
- Envelope-Follower + Audio In (seperate Ins)
- much faster / wesentlich schnellere Hüllkurven / Modulation
- 2 (plus "Global LFO") statt/instead of 1 LFO
- 4 ModulationsKnoten statt 2 Knoten / 4 mod routings instead of 2
- 9 zusätzliche, feste Modulationswege / 9 more mod routings
- Viel mehr MOD Quellen und Ziele verfügbar / more mod sources
- ziemlich komplexer Sequencer / sequencer
- mehr Rozz / more lofi FX
