I’ve kinda A/Bd the Hydrasynth Desktop and the Minifreak a bit.
First of all I think some of your workflow problems and “disassembling patches” as you say is probably more to do with the Explorer having less screens. It was really designed for the 4 screens so I can see how navigating the mod matrix on that could be a pain. That said, you’re not wrong that having the majority of the mod matrix in front of you like on the Minifreak is a huge convenience.
I’d say when it comes to the basic wave shapes the two synths sound identical. We may have finally mastered the art of digital Squares and Sawtooths! But for real, there wasn’t any different to me unlike other synths (Moogs lineup) which have a very beefy sound to them.
The Microfreak does have a couple engines that the Minifreak doesn’t have yet and I bet more likely than not they will come to the Mini. Most notably the Wavetable synth with user wavetables. I do love the Hydras wavetables and how you essentially can build your own but at a certain point all that shit sounds the same and that goes for ALL wavetable synths. The Minifreak has a great selection of algorithms to choose from and I don’t think you will feel like you’re missing out on anything.
The filter is a good sounding filter it just lacks the character. Like I’ve said above you’re not getting a noticeable taste to that filter and I’d say the default LP on the Hydra sounds quite similar. It would have been nice if we could drive the analog filter because yeah, there’s not a lot of analog flair going on. But it’s fine, just lacks that little salt and pepper I’d expect from an analog filter.
I do think the workflow between the VST and the hardware is phenomenal though and if that’s what you’re going for you’re going to get much more out of this synth than the Hydra for sure. The plug-in and the hardware sound identical to me and the process of loading up presets you’ve made in “standalone” is seamless. Arturia killed it on this aspect and it is absolutely the major selling point for this synth in my mind and makes up for the “ok” filter.
I can’t compare to the keys of the Hydra. Obviously you lose poly after touch. The Minifreaks keys feel similar to my Keystep (I have the standard one). They do feel slightly better even but I have had my Keystep for 5 years. After the first update the touch sensor buttons also feel much more responsive. I still would have preferred physical buttons but this isn’t a pain point any more. It wasn’t bad it would just be noticeable that I’d have to make an effort to press things where now it works how I’d expect. It’s probably like a 1-5% change that made a good difference.
The sequencer on the Minifreak is also a lot of fun. It’s only 64 steps but it’s saved per sound and you can run it and play on top of it or you can control the pitch like a custom arp.
You do lose out on all the good modulation sources having 5 LFOs and 5 envelopes on the Hydrasynth but it’s not as big of a deal in my opinion as with the VST and a DAW you can easily get even more LFOs and Envelopes if you choose. Ableton, Bitwig, and FL Studio all offer Midi LFOs and Envelopes so you really don’t lose that in the workflow you’re describing.
Last thing, in terms of effects I’d say the Minifreak is the clear winner. The reverb especially is much better on the Minifreak to where it’s actually usable. The init reverb on the Hydra is horrible but even after some taming with the filters and dampening it’s still extremely metallic to me. The Minifreak is closer to what you get on modern (Digi) style elektron box so it’ll probably sit better with your Syntakt. And I won’t touch on the rest of the effects but again, overall winner is minifreak here for me. Also with the effects they are much more flexible in routing. You can of course turn the second oscillator into some unique FX but you can also but the reverb at the beginning of the chain or whatever where the Hydra really just has those two slots and the delay and reverb are in static positions.
I do think you’ll be happy with the Minifreak if you choose to switch especially considering how much the VST sides of things interest you.
