Studiologic Sledge v2.0

control of a futuristic musical 
spaceship! Above all, the Sledge is 
intuitive with almost zero learning curve 
so both beginners and seasoned 
programmers will appreciate it. 
Moving on to the sound engine, this 
has been co-designed with Waldorf and 
I really dig the overall sound and 
character. It sounds less industrial 
compared to its Blofeld cousin with 
more general ballsiness and the overall 
vibe can be best described as warm and 
full with a defi ned edge and a nicely 
analogue texture. The Sledge excels at 
bright, brassy patches, low fi ltered pads, 
warm mono leads and snappy bass 
sounds (courtesy of the fast envelopes); 
though, with 66 PPG wavetables 
onboard (and now user samples too), it’s 
capable of a wide range of new and 
more otherworldly textures not 
previously available on the original 
Sledge OS. 
New waves
Of the three VA oscillators, Oscillator 1 
is the most interesting as, in addition to 
the standard sine, triangle, square, saw 
and variable pulse waves (these are 
available on all three oscs), you’ll also 
fi nd the aforementioned 66 wavetables 
including types such as Karplus Strong 
(for emulating plucked/percussive/
hammered sounds), plus organs, 
formants, sweeps and more (note: user 
samples are also selected via Osc 1). 
However, the Sledge’s big ace card is 
that you still have a further two 
oscillators available to layer along with 
samples or the wavetables and there’s 
now 24-note polyphony which is 
especially handy when building more 
complex poly-patches/layers.
Modulation-wise there are three mod 
busses (two LFOs and one for the mod 
wheel) with speed and depth controls, 
each with six waveshapes and six 
destinations including wave/FM and 
PWM, plus an arpeggiator. The sine/
triangle waves of Osc 2 can also be 
FM’d by Osc 1, whilst the sine/triangle 
waves of Osc 3 can be FM’d by Osc 2. 
It’s surprisingly easy to create DX-esque 
basses, pianos and strings, plus there’s 
oscillator sync, mono/poly modes with 
single/multiple triggering and 
polyphonic glide, although monophonic 
glide only triggers when playing legato.
The Sledge also offers up a versatile 
multimode fi lter featuring LP, BP and 
HP modes with 12dB/24dB slopes and 
the fi lter types sound authentic to 
classic analogue designs – the cutoff 
has a wide range, opening brightly in 
the tops for cutting leads and 
Oberheim-style brass patches but things 
can go nicely deep 
and powerful in 
the lows for 
Moog-style basses 
and huge subs. 
The resonance 
sounds powerful 
and liquidy (watch 
your speakers!) 
and the fi lter self-oscillates too, so you 
can use the resonance for creating 
authentic analogue kicks and more. 
The drive feature sounds a little 
brittle but it dirties things nicely at 
lower levels whilst there’s also pink and 
white noise for making FX and drums. 
Finally, there’s a great chorus/phaser/
fl anger and separate/simultaneous (and 
very usable) reverb and delay units, 
(though I hope Studiologic can address 
the clicking through the audio path 
when selecting different effects).
To conclude, I’ve always liked the 
Sledge’s sound but things just got a 
whole lot better with v2.0. The fact that 
you can now use delay and reverb 
together, coupled with PPG wavetables, 
aftertouch, samples, FM, 24-note poly, 
splits/layering, all at an RRP of £799, 
makes Sledge v2.0 a real steal! 
It excels at bright, brassy patches, 
low fi ltered pads, warm mono 
leads and snappy bass sounds

ALTERNATIVES
 Nord  Wave 
 £used 
 There are still some NOS 
models about, or check out 
the used market. The Wave 
has a lot in common with 
the Sledge – it’s a great 
sounding VA synth with 
wavetables and user 
sample facility.

 Waldorf  Blofeld 
Keyboard 
 £479 
 The Blofeld also has a lot 
in common with the Sledge 
– they’re both Waldorf-
designed VA synths with 
arpeggiators and 60MB 
of user sample memory, 
though their sonic 
characters are 
nicely different.
