Complex Oscillator Synth
Description (

Hilda is a Complex Oscillator Monosynth, inspired by the most interesting aspects of both west-coast and east-coast synthesis techniques. You'll find a wave folder, lowpass gate, and audio-rate modulations, but also a 12-mode filter and traditional VCA circuit. All parts of the instrument are carefully circuit-modelled to sound as analog (or digital, where applicable) as possible. It's like a best-of-all-worlds semi modular synth, but without the patch cables. The unique mix of different synthesis components adds up to a unique sounding electronic instrument, which can be used as a playable synthesizer, a MIDI sequencer and an audio effect for external audio - or any combination of those three. - Full Audio Unit compatibility (AUv3 instrument, audio effect and MIDI processor modes supported) - Universal design (iPhone and iPad; iPad Air 2 or higher recommended) - Built-in analog style 16 Step MIDI Sequencer with custom scales - 12 mode filter, based on the Oberheim Xpander design - Drone mode lets you [partially] bypass the VCA/LPG and just go with the flow - DIY Lo-Fi digital delay circuit emulation - Live pads with effects that can be triggered via the UI (or via exposed AU Parameters) - All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice) - MIDI Processor plugin mode disables synth to save CPU - Carefully handcrafted by yours truly, to capture the essence of my love for tinkering and experimenting with sound :-) Find the user manual on ruismaker.com}

This is a wonderful synth. Lots of fun to play and improvise. As someone else said before, it would be great to have recording capabilities.

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

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!

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.

Injustement méconnu, génial pour créer des drones psyché ou des séquences d un autre monde. Le son est excellent 👌.

The fact people compare this to quality made hardware like 0coast and Moog is outright laughable. Its another software toy. Fun but certainly not in the same league as MN. 🤣 Well Done Bram, now run along and go update your older apps to fit a modern iPhone screen. You money grabbing clown.

And that’s the last straw. Universal app my tooshie. I have not bought an Apple app in months because of continued decay of quality and this is the last one. It won’t play in the background using it as a Universal App. Seriously? It won’t save state even upon exit. The developer zoomed in for the iPhone photos, that’s deceptive. The pamphlet is NOT a manual. This is pathetic and it’s taken as good quality. Well for the iPhone 12 it’s a joke and the end of Apple App purchases. It’s just a waste of money. Goodbye.

Super inspirational analog ’hardware’ sounding synth that keeps on giving new and interesting sounds. Although it might look a bit intimidating at first sight, it’s not that hard to get something interesting going, and personally the best approach is to just throw the manual away and just dive in and start tweaking! The sequencer is awesome and can also be used to sequence other synths as well. Hilda can also be used as an fx. Great for techno, drones and all things weird. Highly recommended.
