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..

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 (lin/exp).

new: Tube Filters!

4-OP FM with 7 Algorithms.
2 free digital waves, 14 internal waves

specialized on nasty and evil sounds, also LoFI.but can sound nicer also but has a special LoFi Section.

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
