Description
Diodow is a virtual synthesizer by HrastProgrammer for building sounds with analog-modeling oscillators, filters and a deep modulation system. It combines four oscillators with four ladder filters, giving sound designers several ways to shape the signal before adding movement.
Each oscillator can morph between saw and sine shapes and has its own sample engine for blending WAV material with synthesized tones. Oscillator sync, frequency modulation and filter controls provide further options for creating evolving patches.
Four LFOs and four five-stage envelopes feed modulation options that include a 16-slot matrix and a separate MIDI-rate matrix. The envelopes can loop, while tempo synchronization is available for LFOs and delays.
The current X2 release includes a bank of 100 patches, and the developer says its sample engine adds high-quality interpolation. Diodow saves voices as separate files, and its AutoMod system lets host automation control modulation sources instead of directly automating individual synth parameters.
Diodow runs in a Windows VST2 host; the developer has retired earlier builds and Linux versions. Its unconventional interface and manual patch workflow reward experimentation, though users accustomed to modern preset and automation handling may need time to adapt.
Frequently Asked Questions
Which systems and plugin formats does Diodow support?
The current X2 version is for Windows and requires a VST2-compatible host. The developer has retired the older builds and Linux versions.
Does Diodow include presets?
The developer includes a bank of 100 patches by Ed Ten Eyck with the download. Voices can also be saved and loaded as separate files.
Can I automate Diodow from my DAW?
Diodow uses AutoMod parameters as modulation sources rather than direct automation of individual synth parameters. Assign an AutoMod source in the modulation matrix and automate that source in the host.
Can Diodow use samples?
Yes. Each oscillator has a sample engine that can load WAV files and combine them with the oscillator signal.
