Drolo Molecular Disruptor V 2.0 User manual

Molecular Disruptor V 2.0
drolo
The Molecular Disruptor is a DSP based multi-effect pedal that can be loaded with 8 patches selected from the molecular
patches list: http://www.davidrolo.com/molecular-patches/
This list is regularl being updated with new patches.
These patches get programmed after the purchase and cannot be changed b the end user.

Connecting and powering:
The power suppl needs to be 9V/100mA center negative like the common BOSS power supplies:
Make sure the polarit of our power suppl is correct or it will damage the pedal. Do NOT run at higher voltages.
As the pedal uses a digital processor operating at high frequencies, ou ma hear some high pitched noise if ou use it
together on the same power suppl with other pedals (dais chained) even when it is b passed. The noise can bleed
through the power suppl into the other pedal’s signal. This is normal for such devices. It might not be the case in our
particular setup but if ou notice that, I would suggest using an isolated power suppl .

bypass switch: If ou give it a short tap (<1sec) it acts in latching mode.
If ou press it for more than a second the b pass indicator led will start flashing and ou are in
momentar mode.
tails: Defines the b pass mode.
Up : Buffered b pass that leaves the output of the effect passing through when the pedal is b passed,
allowing dela s to trail off etc. Note that this will mean that an patch that generates noise ma be
audible when pedal is b passed. Use the Down position in those cases.
Down : Rela , true b pass, no dela tails.
function switch: Depending on the hi/lo switch setting it will set the p0 value to its minimum or
maximum when pressed. In some patches it can be used to tap a tempo or latch a state (hold).
hi/lo: Defines how the function switch will work.
hi: maximizes p0 value when pressed.
low: minimizes p0 value when pressed.
patch selector: Select one of the 8 loaded patches (Note: When ou change to a different patch, an sample that was
held or looped in the previous patch will be deleted).
p0, p1, p : Each of these pots controls a parameter whose function will var depending on the selected patch.
fdbk: Usuall serves as feedback (for example for dela repeats), but depending on the patch it can also be
used for other functions or have no function .
wet/dry: Control the level of the wet and dr signals. Unit gain around mid position. (Note: for certain patches,
due to a comb filter effect when mixing dr and wet signals that are too similar ou might hear some
strange phasing. These patches were usuall meant to be used wet onl but ou are of course free to mix
in some dr if ou like the results).
smplrt: Controls the sample rate at which the DSP chip will run. It goes from around 16kHz to 70kHz
Most patches are optimized to run around 30kHz. Increasing the sample rate will have different effects
depending on the chosen patch but as a general guide:
- Audio qualit increases as ou increase smplrt, sample size (dela time) decreases.
- The range of filters goes up as ou increase smplrt.

exp input: Can be used to externall control p1. When an expression pedal is connected, the p1 pot can be used to
define the max setting of the expression pedal.
Most commerciall available expression pedals using a TRS plug should work. The value is not reall
critical, although I would not go lower than 10k.
Some examples are the Moog EP-2, Roland EV-5, and M-Audio EX-P.
You need to use TRS (Stereo) plugs and cables. NO MONO PLUGS OR CABLES! These will short out the
voltage regulators inside the pedal and damage it.
Here is how such a TRS plug looks like.
The exp jack is connected to the pedal like this:
sleeve : ground
ring: 3.3V suppl voltage
tip: controlling (var ing) pin
If ou reall know what ou are doing ou can actuall use a control voltage instead of a
resistance based controller. But ou need to consider the connections and never exceed 3.3V. If
ou do ou will damage the pedal. Use a TRS plug. No Mono plug. TRS, not MONO :)
If ou have an doubt when deciding what to connect to the expression input please send me an
email and I will verif that ever thing is safe.
Thanks :)
