History and modernity meet in the Sequential FOURM

With the FOURM, Sequential presents a polyphonic analog synthesizer with SCI Prophet-5 and Pro-One DNA and a contemporary sound character. The FOURM is not only very similar to the Sequential classic Prophet-5 on the outside: the typical signal path consisting of two oscillators with simultaneously activatable waveforms, mixer, Lowpass filter, VCA and envelopes has been retained and adapted to today's needs in harmonious details such as the feedback circuit. The modulation options also go beyond those of the "P5", as the overhauled modulation bus from the SCI Pro-One is used here. The 37-key slimkey keyboard is equipped with polyphonic aftertouch, making expressive playing a pleasure. Thanks to the shortened keyboard, the FOURM is extremely compact and weighs just 4 kilos. The synthesizer can be played polyphonically in four voices, alternatively there is a fat unison mode and the option to play monophonically. As a classic playing aid, the editable arpeggiator is of course a must and a polyphonic step sequencer is also on board. The FOURM lives from its great basic sound alone, ultimately the sum of all components contributes to this, but above all the modulation bus with AT assignment, which creates sounds that the historical original from 1978 cannot master.
