Cyclone Analogic TT-303 Bass Bot V2
 B
ack in 1981, 
nobody could have 
predicted that over 
35 years later a little 
cheap single-
oscillator synth-and-
sequencer combo 
would still provoke such interest, but 
such has been the fate or Roland’s 
TB-303 Bass Line. Originally 
conceived as a basic bass 
accompaniment machine to partner 
Roland’s TR-606 drum machine, the 
303 was initially embraced by early 
synth-pop artists, but ultimately 
extremely hypnotic and alluring to 
Chicago’s late-night club crowd. From 
this point on, the 303 become 
entwined with dance music and has 
since forged its place as a classic.
Because of its classic status, 
prices for secondhand units have 
risen considerably since a low point 
in the late-’80s, where used 303s 
could be had for under £50. From 
the ’90s onwards, there have been a 
host of software and hardware 
‘clones’ attempting to recreate or 
expand on the sound of the original.
The Cyclone Analogic TT-303 Bass 
Bot V2 follows on the heals of their 
original TT-303 (that memorably 
employed a replica TB-303 case and 
knob design). In this guise it managed 
to last a few years, (undergoing a 
significant OS update to version 2 
along the way) and garner much 
praise for its sonic authenticity.
When testing the MkI TT-303 for 
the first time, it was clear by direct 
comparison with an original TB-303 
that at points they were almost 
indistinguishable. The most obvious 
difference appeared to be in the 
maximum range of certain 
parameters, where the Cyclone 
version could reach slightly further in 
the envelope modulation and cutoff 
department. It’s important to stress 
that, like any vintage analogue kit, 
no two original units sound exactly 
the same. Given that both the MkI 
and MkII TT-303’s employ 
surface-mount components, these 
small differences are to be expected. 
Another extremely important aspect 
of Cyclone’s design philosophy has 
been to build on the the usability of 
the original Roland designs, where 
functional breadth, in the sequencer 
department in particular, was 
somewhat lacking.
The Bass Bot MkI built on the 
awkward step editing of the original 
by adding additional pattern creation 
modes. User Patterns are the core 
stored patterns, used to create tracks 
or to interact with a few of the other 
playable modes. Confusingly, Preset 
Patterns are not fixed, but are 
created by the unit’s pattern 
generation system– much like a 
pattern spawning ground. The MkII 
adds a Pattern Lab Mode, which is 
an extension of the generated Preset 
Patterns, and allows more detailed 
control of what is generated. The 
Loop Edit Mode provides real-time 
editing of User Patterns, allowing 
you to add notes, and alter pitches 
and note modifiers (such as accents 
and slides) on-the-fly. The quirky 
Arpeggiator mode is still present, 
found fame with the rise of Chicago 
house music, especially when some 
strands of its sound become 
harder-edged, giving rise to acid 
house. Phuture’s Acid Tracks is the 
archetypal acid track, and makes use 
of only a TB-303 and a TR-707 
drum machine. This was characteristic 
of what happens when the unit’s 
simple synth engine employs its 
single-stage decay envelope to sweep 
the cutoff point of its distinctive 
filter. With the Resonance control 
pushed up, this gave the whole thing 
a liquid, bubbling quality that proved 
THE PROS & CONS
+
Swing, added in the 
MkII, is great for 
adding extra vibe
Bigger knobs really 
make a difference 
when tweaking
Note entry, pattern 
generation and 
manipulation 
methods make 
music creation a 
more enjoyable 
experience than it 
was on the original
-
Analogue Clock –  
it’s great to have 
analogue outs,  
but there’s no  
input or adjustable 
PPQN parameter
Parameter 
automation  
isn’t supported 
under internal or 
external control
