Eurorack compatible version

TipTop Audio has realized in cooperation with Buchla a completely Eurorack compatible version of the fourfold function generator. Each of the four identical units has a mode switch that selects between Sustained (envelope, long gate), Transient (envelope, short gate) and Cycle (LFO). The two parameters Attack and Decay have a setting range of 0.001ms to 10 sec, which is very suitable especially for percussive sounds. In addition, the two controls adjust the frequency and waveform in LFO mode. Control voltage inputs for the two phases as well as gate inputs for triggering the envelope and activating the cycle mode allow lively and complex modulations. At the outputs you find the CV output and "End-of-Phase", the latter is a trigger signal that is released when a modulation cycle expires. With thoughtful patching within the module, complex, self-generating modulations that even extend into the audio range can be created. The quadrature outputs are a special feature, they combine the channels A&B as well as C&D in pairs and shift B and D and up to 90° degrees to A and C, which again increases the complexity of the possible modulations.
