Tiagolr Sirial is a new free, open-source rhythmic delay plugin for macOS, Linux, and Windows inspired by the Soundtoys EchoBoy Tap mode.
The market for open-source plugins has grown significantly in the last two years. A major player is the developer Tiagolr, who has been shaking up the free plugin market since last year. Among other things, he released the RipplerX synth, or the beautiful, lush QDelay.
He’s just pulled another delay plugin out of his creative pocket. Tiagolr (or short Tilr) has released Sirial, a new versatile rhythmic delay plugin.
Tiagolr Sirial
Sirial is a new, open-source, creative rhythmic delay plugin for macOS, Linux, and Windows. Like its previous plugins, it also has a role model. According to Tiagolr, Sirial is loosely inspired by the Soundtoys EchoBoy tape mode.
Yes, it draws inspiration from the EchoBoy tape mode, but with the novelty of using serial delay lines instead of delay taps. This has the advantage of creating multi-tap delays with a natural decay (optional) and coloring of standard delays.
He also says they produce a more pleasant, realistic sound, and that any effects on the feedback path are applied to each tap, as with normal delays. Plus, you can also achieve classic modes like ping-pong or cross-feedback, which are difficult to create with delay tapes.
That’s why the plugin is called Sirial, to allude to the serial aspect. In total, you can work with 16 serial delay lines to build intricate delay patterns. Stereo taps are possible with different adjustable offsets for left and right channels.
Only Classic Shaper
There is also a dedicated ping pong mode where the feedback is crossed on each tap, as well as a reverse mode.
Unlike its previous QDelay, Sirial offers only basic effects such as dampening, saturation, and diffusion, and they are available only on pre-or post delay. You can add any pre- or post-FX outside the plugin in any DAW.
The reason there are only classic effects here is due to the CPU. Since the processor applies them to each tape, it computes each sample across 16 delay lines and 2 channels, significantly increasing the CPU burden.
Further, it has a ducking option with controls for threshold, amount, attack, and release. Tiagolr ships his new plugin Sirial also with various factory presets.
First Impression
Another great open-source plugin from Tiagolr. A bit simpler than QDelay, but still another highlight you shouldn’t miss.
Tiagolr Sirial is available for free download now. It runs as a VST3, AU, and LV2 plugin on macOS (native Apple Silicon + Intel), Linux, and Windows. It’s open-source under the GPL-3.0 license.
