Polyphonic semi-modular virtual analog synthesizer with built-in pattern sequencer and a filter based on the classic music composer 202 Imagine a 303 on steroids – that’s what we created with Semi Modular X (ASM1X). Collaborating with our friend AlphaDog, we enhanced the mock-up with additional features like patch cables and polyphony. The result is a truly unique and versatile instrument. Although ASM1X has its roots in sequenced synth sounds, it stands out for its exceptional pads and leads, making it a hidden gem for producers. One thing is for sure – nothing else can replicate the distinctive sound of ASM1X. The heart of ASM1X is its 202 filter, known for its self-oscillating resonance, precise tuning, and wide frequency range spanning from sub-bass to beyond the upper limit of human hearing. This filter has a powerful voice that can truly captivate. Most of the modules in ASM1X support control voltage (CV), allowing real-time signal path modifications without any audio glitches. The sequencer features CV Gate/Note output and is compatible with playing ASM1X in Note mode, monophonically, or polyphonically.
