VCO digital Flame 4 VOX
The 4Vox is a quad wavetable oscillator with up to four voices per VCO, resulting in a maximum of 16 voices at four individual outputs. With the MIDI In the module can be played both with CVs and directly via MIDI which also allows for modulating some additional parameters. There are 39 memory locations for wavetables and 32 for all global parameters of the VCOs.
