Review: Hail Hydra(synth)! - Hope someone got a chuckle out of my headline. I couldn’t resist. 😊 This synth has been on my radar since its release a few years back, and I finally decided to go for it. I was debating between the Hydrasynth Desktop vs. Explorer, and the “Polytouch” keys on the Explorer won out. Really glad I got a keyboarded model. For the price, this is one awesome, versatile synthesizer. Compared to most other “mini” keyboarded synths in this price range, the Hydrasynth Explorer has an excellent build quality. Solid knobs, nice rubber buttons, good backside connectors, responsive pitch and mod touch strips, and a very decent “mini” keybed. This is a nice compromise compared to a full sized keyboard - doesn't feel like a toy! Of course, what’s most important here is the sound. First off, it’s worth noting that the sound engine on the Explorer is the same as its bigger siblings. With the exception of the Deluxe model (which is capable of layering voices), they all share the same factory patch banks. It was a really good sign that after setting this up I spent about a half hour just playing around with the first 15 or so presets in bank A. No speed through presets here, they were all that good (at least to my ears). And this synth has 8 banks of 128 patches. Punchy basses, beautiful evolving ambient pads, shredding leads – absolutely tons of sonic potential here. Cool randomizer feature – You can randomize an entire patch, or focus on a specific area to roll the dice on. Lots of performance options here as well: Back to the keyboard - This is my first polyphonic aftertouch enabled keyboard, and I was very pleasantly surprised at the expressiveness I could coax out of many of those first few patches. Again, so glad I went with the Explorer! Three nice sized dedicated knobs in the filter section that you can sweep while playing. Pitch and Mod touch strip controls (Instead of levers. They work fine). And one killer arpeggiator, with its own set of dedicated controls. Perks Additionally, there’s a couple things about what's included with the Hydrasynth Explorer from Ashun Sound Machines that are worth noting. First, the included power adapter that came with this synth has a long power cord. Seriously, the cord is probably about twice the length of what you usually get. Handy. Second, the accompanying manual is 98 pages of CLEAR, readable English. :)
Review: READ THIS : IMPORTANT INFORMATION - I just opened the box & have only read the instruction manual & I am BLOWN AWAY! I have NEVER experienced any instruction manual like this in my life & I am in my 60's. The manual is huge & contains everything you could possibly want to know in an orderly & fantastically organized concise language. I am not joking folks - This manual all by itself is a work of art! Included is the POWER SUPPLY UNIT (fricking unheard of ya'all!) The deck of the unit is so logical & ergonomic it mystified me. I will return after I have explored it but right now I can say without any hesitation that BANG FOR THE BUCK there is no comparison . . . Wait until you see this instruction manual, you won't believe that it's real . . . It is AWESOME! UPDATE - I have been completely lost in a spectacular sound realm, wandering around sonically in a beautiful hypnosis. I keep hearing Isao Tomita's ghost & I am consumed with gratitude. This HYDRA is just astounding! There are a thousand ways to gamble your investment on a lot of specialized proprietary sound machines & once you take the bait your begrudgingly locked into an array of peripherals that you never bargained for slowly chewing away at your wallet . . . Not here! This is a SOLID investment, far & away the best money I have ever laid down. Astounding, Amazing, Incredible!
