Based on the BUCHLA hardware model of the same name, the SOFTUBE BOOKLA 259e is an add-on for the in-house virtual MODULAR. The 259e is a dual oscillator with modulation VCO and a complex main VCO. The frequency range of the main oscillator (dual wavetable-OSC) extends over 8 octaves, while the MORPH parameter fades between the two simultaneously read wavetables. A total of 8 banks are available, which can be switched between with TIMBRE. Banks 1-5 are pure wavetable banks, while a-c digital "Mülll" read out and reproduce impressive sounds. The WARP controller is responsible for the integrated digital waveshaper and works, as with MORPH, also by means of virtual control voltage as required.
