Beautiful!

This synth keeps on giving. Automation or manual change of the drone level is one of the many cool things…

„Einfach“ gut

Mein liebster digitaler Synth. Wild und verstörend 🔈

Deep and Unique

I held back on getting Hilda because it wasn’t the kind of synth I was used to. Then I bought it, and it was true love, because it wasn’t the kind of synth I was used to, lol. Hilda will reward experimentation with sounds you’re not likely to get anywhere else!

Magic subconscious creativity

Resisted getting this for a long time, always skeptical of West Cost synthesis. Then they dropped the price and I’m glad I got it. Meditative and relaxing.

So good

Very very nice synth. Would love an A & B patch morphed like the Arturia Polybrute
