ASM Hydrasynth
FM VERDICT
 9.4 
I mpressive fi rst release. 
Looks and sounds great, 
invites exploration, built 
to last but not overpriced. 
What’s not to like? 
 RIBBON  CONTROLLER:  Use this 
full-length ribbon (CS80-style) to 
control modulation and pitch, or as an 
instrument in its own right 
 MODULE  SECTION:  Access for all the 
main areas of the Hydrasynth’s engine 
including oscillators, mixer, fi lters, 
envelopes, mutants and effects 
 KEYBOARD:  It may look 
unremarkable but this keybed has 
poly aftertouch. Hold a chord, wiggle 
one note – instant pleasure! 
 CV  INTERFACE:  For all of the 
modular-heads out there, the 
Hydrasynth offers up plenty of easily 
accessible CV connectivity 
setups too, so that your favourite 
buttons’ macro setups can be applied 
to any of your custom patches. 
Macros can also control mod-matrix 
mod routes too (again, much like 
‘control routes’ on the Alesis 
Andromeda – which give you a way to 
‘interrupt’ the mod paths). 
Talking of mod routes, there are 
32 here and really, you can let your 
imagination run wild! Setting up mod 
routes is super-fast and can be done 
in and out of the Mod Matrix page 
(accessed by the Mod Matrix button). 
Simply hold any source (LFO1 for 
example) then hit your desired 
destination (fi lter cutoff for example), 
tweak the level and you’re set. You 
can modulate the excellent effects 
too (which is always something that 
impresses me), greatly increasing the 
Hydrasynth’s versatility. 
The ‘module select’ area gives you 
fast and direct access to all the main 
modules that make up your sound. I 
like that you can instantly see what is 
being triggered by a key press, (for 
example the envelopes and LFO 
buttons will light up, if assigned). All 
familiar sound building blocks are 
nicely presented here including 
oscillators, envelopes, fi lters, amp, 
mixer, LFOs, noise and effects. 
However, this is the Hydrasynth and it 
isn’t conventional in any way! Firstly, 
you have three oscillators per voice 
which include standard waves, plus 
wave-scanning (an intuitive type of 
wavetable synthesis where you can 
assign eight waves and scan through 
them using a dial/mod route). Then 
within the ‘mutants’ you’ll also 
discover linear FM, plus unique types 
of pulse-width modulation. In 
addition, there are fi ve (looping) 
envelopes per-voice, an amp module, 
two fi lter modules, fi ve LFOs, reverb 
and delay modules, plus pre and post 
effects. In essence, all you’d likely 
want in terms of sound design is here, 
directly accessible and mostly 
modulatable! And as powerful as this 
looks on paper, this is refl ected in the 
sound too. 
General sound quality is truly 
excellent (precise and crisp yet it can 
be warm and textured) whilst the 
resulting sounds can be anything 
from high quality ‘bread and butter’, 
to unique sounds that you’ve truly 
never heard before. Inject the ribbon 
controller, arpeggiator, macros, mod 
routes and of course the poly 
aftertouch (and very musical 
sounding effects/drive) and you’ll be 
churning out refreshing new sounds 
fast! Admittedly, there is a shallow 
learning curve but that is to be 
expected with the level of complexity 
onboard. With deep synths like the 
Hydrasynth, it’s always advisable to 
draw mental maps of your sounds 
fi rst, then go in (and I suggest reading 
the manual too), but if you’re into 
modular then the Hydra will be very 
fast for you to get to grips with due to 
its module-based layout. Alternatively, 
to get exploring quickly, you can just 
hit the random button and shoot the 
breeze; sometimes results will be, 
shall we say, a bit off, but then gems 
will appear that can be great starting 
points, or great sounds in themselves. 
As a fi rst new synth from a new 
company, the Hydra is hugely 
impressive all round (and this is not 
an easy thing to achieve on the fi rst 
throw)! Build quality, looks, features, 
sound – it has it all and at a price 
that is actually affordable too. Let’s 
also not forget that there’s a beautiful 
rackmountable/desktop version too 
(with all the features but pads instead 
of keys). Congratulations to ASM on a 
brilliant machine!
