Instead of a traditional review of the Sequential Fourm, we decided to take a different approach: putting it to work on a specific track. And not just any track: "Fade to Grey" by Visage—an absolute classic of 1980s British synth-pop. Every melodic and accompanying track you’re about to hear was created exclusively using the Fourm, starting from factory sounds (drawn from the approximately 300 initial presets) with only minimal tweaks. The only element not provided by the synth is the drums: an AI-generated Roland CR-78-style pattern, occasionally reinforced with a kick and snare from Logic’s sound library.

Along the way, Pablo demonstrates how to truly harness the power of a modern polyphonic analog synthesizer: polyphonic aftertouch (key for the lead vocal line, where some notes come alive while others fade out completely), intense mixer feedback (ranging from subtle thickening to nonlinear behavior with "ghost" harmonics), audio-rate filter modulation from Oscillator 2 (adding anything from brightness and vocal-like character to total sonic breakdown, depending on the intensity), glide for creating transition sweeps, and the LFO in random mode feeding the filter to ensure every note sounds unique.

We also cover specific recording techniques: layering basslines via MIDI using two different sounds and panning them; doubling hand-played pads so that the two takes aren't identical; and recording a MIDI pattern to free up both hands, allowing you to perform real-time timbral tweaks—adjusting the filter, resonance, and modulation intensity—during the actual audio recording.

📝 A quick refresher on the Fourm: a compact 4-voice analog synthesizer featuring two VCOs per voice, a 4-pole low-pass filter derived from the Prophet-5, one global LFO, two ADSR envelopes, a mixer with feedback capabilities, no internal effects, a mono output, a 37-key "slim" Tactive keyboard with polyphonic aftertouch, and a modulation matrix—inherited from the Pro-1—that is directly accessible right on the front panel. 00:00 Original vs. Fourm Version
