Sequential - Fourm

On the Sequential Fourm keyboard, you'll immediately feel the responsiveness offered by polyphonic aftertouch, a feature that allows you to sculpt each note like a living material, extending your gesture well beyond the initial attack. You could imagine using it yesterday to give a striking expressivity to an old standard or tomorrow to invent a never-before-heard melody, and in each case the instrument responds to you with a sensitivity that transforms your playing into language.

Its 4 polyphonic voices are based on a 100% analogue architecture, directly inspired by the Prophet-5, and this historical link is not limited to a simple wink, but is embodied in the precision of the envelopes and the dynamics of the 4-pole resonant low-pass filter, enhanced by bass compensation. In the past, this technical detail changed the way bass took its place in a mix; today, it changes your relationship with sound, and tomorrow it will change the density of your creations, because you can count on a warm, nervous and consistent sound.

Each Sequential Fourm voice has 2 oscillators capable of generating several waveforms simultaneously, and oscillator B can even be transformed into an LFO to introduce moving, almost unpredictable modulations. As you route these sources through the matrix on the front panel, you can compose live textures that didn't exist the second before, and you could, by simple intuition, produce an atmospheric carpet, a trembling bass or a moving layer without ever interrupting your creative flow.

The Sequential Fourm's modulation matrix, inherited from the Pro-One, has been placed on the front panel so that you can interact with your ideas without going through menus or screens. So you can link a source to a destination with a simple gesture, immediately visualise your diagram thanks to the colour codes, and imagine sound paths that take shape almost like a mental map. Yesterday, this kind of configuration would have taken several minutes on another instrument, but today it only takes a few seconds to trigger daring combinations and feed your inspiration without ever lifting a finger.

Sequential Fourm's built-in arpeggiator and sequencer mode opens up a playground that reinvents itself with every measure. You could record a repetitive pattern and transform it into a hypnotic structure, or use the step-by-step glide to draw out more sinuous phrases, and each time the instrument leads you back to new rhythmic possibilities. With 128 programmable memories, you can save your discoveries and recall them in an instant, whether you're in the middle of a rehearsal or in the silence of the studio, ready to restart the creative machine.

The Sequential Fourm's feedback circuit adds extra character, almost like an organic saturation that densifies your timbres. You can play with this reserve of raw energy like you would a spark capable of igniting an entire mix. This detail, combined with the independent ADSR envelopes and the freedom offered by the oscillators, creates a sonic palette where every technical nuance has an immediate impact on your expression. And when you come back to an old programme, you'll find this material with the same intensity, as if nothing has been erased by time.
