Arracis Gold

Arracis Gold Pro is a four oscillator step sequencer synthesizer with a large number of built-in sample waveforms which can be switched and modulated in up to eight steps per loop (host synced, common note values, dotted, triplet). The stepper can advance regularly or in an irregular fashion (e.g. every 5th step). The sound is then shaped by a resonant LP-HP filter combination, a "spook" effect (kind of a phaser-flanger-delay), a bass enhancer and a synced stereo delay effect with pan modulation.
Most modulation targets allow selection between two synced LFOs, two unsynced special wave LFOs, two slow LFOs and an S/H modulator source.

The user interface is beatuiful. Except for some parameter assignments where I wondered which dial belongs to which parameter first, it nicely fits the instrument

Arracis Gold Pro is well suited for eerie sound scapes, beautiful undulating pads, melodic sequence and arpeggio lines and rhythmic textures.
The wealth of parameters with sensibly tuned value ranges and its vivid sound shaping possibilities make Arracis Gold a nice instrument for live performance. Just feed it a single note or a simple melody and tweak the parameters for minutes and hours.

Arracis Gold comes with a huge selection of beautiful and expressive factory patches and lots of very detailed and varied waves.

My ratings:
UI: 8/10 (a bit of confusion is possible, otherwise really nice and clear design)
Sound: 9/10 (lots of interesting and surprisingly complex sounds possible)
Features: 9/10 (good selection of features with a limited number of building blocks)
Documentation: 8/10 (comes with a PDF document which explains every control element and what it does.
Presets: 9/10 (lots of expressive sounds and a broad spectrum of integrated waves)
Support: 10/10 (the author of Arracis Gold is very responsive. I reported an issue, a day later it was fixed)
VfM: 10/10 (This plug-in is more than worth the asked price [free / EUR 25,-)
Stability: 9/10 (rarely slightly unexpected sound possible otherwise rock solid for me, does what it's supposed to)

I really like Arracis Gold.
