ASM Diosynth is a two-voice hybrid desktop synthesizer with analog filters and a digital oscillator section — a design by Asad Kachaturian, the creator of the ASM Hydrasynth. The Diosynth combines two independent voices, each equipped with its own oscillator section, filter, and envelope, creating an instrument specialized in building complex, dense textures through mutual voice modulation. The defining feature is cross-modulation between voices: Voice A can modulate Voice B and vice versa, with a full modulation routing matrix. Oscillators are digital wavetable with the ability to import custom waveforms via USB. Filters are analog multi-mode (LP, HP, BP, Notch) with resonance. Released 2025, currently in serial production. Price: approximately $1,099.
Two voices, cross-modulation, and analog filters
The Diosynth's architecture is built around the concept of two synthesizers in one — Voice A and Voice B can operate fully independently (dual mono), in unison (stereo pair with detune), or in cross-modulation mode, where the signal, envelope, or LFO of one voice modulates the parameters of the other. The latter produces sounds impossible to achieve in a typical mono or polyphonic synthesizer: living, organic interactions between two slightly different parameter sets that drive each other. Each voice has its own wavetable oscillator with 8 independently addressable wave positions and per-position LFOs — a mechanism modeled on the Hydrasynth Wave Mutant, but limited to two voices for specialization in dense drones and pads. An analog filter per voice with resonance capable of self-oscillation and filter FM. Multi-segment AHDSR envelopes per voice.
Sequencer, effects, and interface
A built-in 64-step polyphonic sequencer with per-step parameter automation enables building complex, evolving sequences without an external controller. The physical interface is based on a combination of encoders, switches, and an OLED display. Built-in effects: chorus/ensemble, MIDI clock-synced delay, and algorithmic reverb. MIDI: USB + 5-pin DIN In/Out. Audio outputs: stereo TRS 6.3mm. An audio input allows processing external signals through the analog filters. Power: USB-C or DC adapter. Enclosure: desktop with a tilted control panel. The Diosynth is positioned as a specialized instrument for building drones, pads, modulated basses, and ambient textures — not as a fully polyphonic general-purpose synthesizer.
