MODBAP MODULAR BY BEATPPL
Modbap Modular is a line of eurorack modular synthesizers and electronic
music instruments by Beatppl. Founded by Corry Banks (Bboytech),
Modbap Modular was born of the Modbap Movement with a simple
mission to dev tools for beat driven hiphop leaning modular artists. It is
our goal to develop eurorack modules from the beatmaker’s perspective
while adding value for music makers of all genres.
It’s almost impossible to explain Modbap Modular without answering the
questions; “So, what is ModBap?” MODBAP is the fusion of modular
synthesis and boom-bap (or any form of hiphop) music production. The
term was created by BBoyTech as a denotation of his experiments with
modular synthesis and boombap music production. From that point
forward, a movement was born where like minded creatives built a
community around idea of Modbap. Modbap Modular is in effect, the
result of that movement in a space where we’d previously not existed.

About Us
TRANSIT
Transit is a fully featured compact 6hp dual stereo channel lane eurorack
formatted mixer. It offers easy signal mixing, gain staging, ducking, and
performance-oriented mutes. Transit is just as comfortable as the single
mixer in a small eurorack case and is equally at home with several
Transit’s supporting a larger system conguration. Transit makes a
perfect combo with Per4mer racked into one of our Modbap20 cases or
coupled with Osiris. Transit has two stereo channel lanes of audio with an
all-analog signal path. A mono signal into the left input sums to the right.
Each stereo channel lane has its own input gain control, mute button and
ducking input. The ducking input on each channel operates like a
traditional sidechain on a compressor where a CV or Trigger input i.e.
LFO, Clock, Gate modulates the gain reduction of the audio. Transit offers
a main stereo output controlled by the master volume control knob and an
independent 3.5mm headphone output controlled by its own headphone
level knob. Digitally controlled colored LED’s for each stereo channel
lane, indicate levels. Red indicates mute. Similar for the Master and
headphone levels which also have their own LED’s for level indication
using the same color scheme.

INSTALLATION
Follow the installation instructions carefully to avoid module or rack damage.
1. Ensure the power connection is disconnected before installing the device.
2. Identify a 6HP free location in the rack to install the module.
3. Connect the 10 pin connector from the IDC ribbon power cable to the header on
the rear side of the module. Ensure that the pins are aligned correctly with the
red stripe on the ribbon conductor closest to the -12V pin on the header.
4. Do not connect the 16 pin header on the module to the power. This is used to
connect compatible expansion module.
5. Insert the cable to the rack and connect the 16 pin side of the IDC ribbon cable
to the rack power supply header. Ensure that the pins are aligned correctly with
the red stripe on the ribbon conductor closest to the -12V pin on the header.
6. Mount and position the module into the dedicated rack position.
7. Attach the 2 x M3 screws by screwing into the 4 locator holes and the rack
mount. Do not over tighten.
8. Power up the rack and observe the module start up.
Cable connected to PSU with
red conductor / edge aligned to
the -12V pin. This should be
labelled on the board.

expansion modules.
Control levels and controls are reected in the respective Tri-color LED’s for
Master level, Mutes and Headphone output level.
