ASM Hydrasynth
 A
shun Sound 
Machines may be 
a new name to 
most of us but 
it’s part of Medeli 
– a well 
established Hong 
Kong instrument maker. VP of their 
product development team is the 
hugely respected Glen Darcey, who 
has conceptualised and brought to 
market products like Arturia’s ‘Brute’ 
range, and Akai’s MPC Renaissance 
and Studio to name just a few! I was 
in no doubt that the Hydrasynth 
Roland-esque end cheeks add a 
nicely industrial look. The only slight 
disappointment here is the lack of 
built-in power supply which would 
have been more fi tting with the 
overall premium feel. 
Moving onto the keyboard, it’s a 
bespoke 49-note keybed which feels 
nicely balanced and positive while 
playing. However it also features 
something quite special in the current 
marketplace: polyphonic aftertouch 
(or ‘polytouch’). This is a big moment 
as it brings poly aftertouch to the 
market at an affordable price point 
and I can say this for defi nite; once 
you try it, it’s hard to go back to 
standard channel aftertouch. For 
those who don’t know, poly aftertouch 
lets you play a chord but just add 
modulation to one (or more) notes in 
it. This is great as you can achieve 
effects played by one hand that can 
sound like a melody and 
accompaniment in one (and still have 
your other hand free). The poly AT 
response is pretty much perfect too 
– not too hard to trigger but not too 
easy either. An achievement on all 
fronts and reason alone to buy it.
would have no detail left unchecked. 
But were my (admittedly high) 
expectations met?
The Hydrasynth arrived nicely 
packed in a sturdy box and – rejoice 
– with a full, printed user manual. It 
certainly feels extremely sturdy, with 
all-metal construction and a unique 
front panel. The knobs feel smooth 
and weighty when turned and the 
clear backlit buttons feel soft under 
the fi ngers and glow a nice orange too 
(the ASM signature colour, very ’70s)! 
While the main panel is all metal and 
painted black, the aluminium 
THE PROS & CONS
+
 Superb build quality 
and classy looks 
 Clear and intuitive 
module-driven 
interface that 
invites tweaking 
A  unique sonic 
personality, 
especially with poly 
aftertouch onboard 
-
 Though  largely 
intuitive, this is a 
complex synth; 
expect a 
learning curve 
 No audio input to 
route things 
through the lovely 
onboard processing 
 Would have been 
nice if poly/unison 
voice modes 
were available by 
the wheels
