Sonoclast MAFD 2hp User manual
Introduction
The MAFD 2hp provides MIDI control of the eight steps of a DFAM. Play a DFAM with a
keyboard, an electronic drum set, a MIDI sequencer (hardware or in your DAW), or any other
controller that sends MIDI notes.
The MAFD 2hp can receive MIDI as a USB device or via a standard MIDI cable. It responds to
MIDI note/velocity, pressure, and mod wheel messages. Any 8 adjacent notes correspond to
and trigger the 8 steps on a DFAM. The velocity jack outputs a voltage (0-5V) corresponding to
the current note’s velocity. The pressure jack outputs a voltage (0-5V) corresponding to any
pressure (aka aftertouch) or mod wheel messages.

Setup Instructions
Follow these steps to get the most out of your MAFD 2hp.
1. Power your MAFD 2hp with EITHER 1) the included 16-pin ribbon cable connected to
your Eurorack power supply OR 2) the angled micro-USB cable included with the
standalone case and power supply. DO NOT POWER WITH BOTH. Both power
connections are on the side opposite of the front panel.
Most MAFD 2hp boards have a notch cut in them so that a 16-pin ribbon cable can
be plugged in either direction for maximum flexibility. When using the 16-pin
ribbon cable, be sure to align the -12V pins (marked on the MAFD’s board) with the
corresponding -12V pins on your eurorack power supply. This may or may not
mean the notch on the ribbon cable goes in the notch on the board. If you are not
sure, ask for help before trying.
2. To the front panel, connect the straight micro-USB cable and/or a MIDI cable to the
DIN/TRS adapter, and connect the other end(s) to a computer or MIDI controller.
3. Patch the MAFD 2hp “TO ADV/CLOCK” jack to the ADV/CLOCK jack on your DFAM.
4. Optionally, patch the MAFD “VELOCITY” and “PRESSURE” output jacks to input jacks
of your choice. The “VELOCITY” jack outputs 0-5V corresponding to MIDI velocities
0-127, and the “PRESSURE” jack outputs 0-5V corresponding to MIDI (poly and channel
aftertouch) pressures 0-127 and/or the mod wheel.
5. The MIDI channel can be set to 8 or 16. Be sure to set your MIDI controller and/or DAW
to send on the channel you selected.
6. If you start up your DFAM and MAFD cold, the DFAM’s first step will be mapped to MIDI
note numbers that are evenly divisible by 8 (0, 8, 16, 24, …)--this means every other C is
mapped to the first step. If the DFAM steps and MIDI notes get out of sync, follow the
next step to re-sync your setup.
7. Calibration: Play the MIDI note into the MAFD that you want to correspond to the first
step on your DFAM. Use the DFAM’s Advance button to get to the first step. (The
DFAM’s sequencer has to be stopped to use the Advance button when the ADV/CLOCK
jack is patched.) Finally, start the DFAM’s sequencer with the Run/Stop button.
8. Play your DFAM!
Optional Case Assembly Instructions
1. Unscrew the four screws on the end of the DFAM to remove the wooden end cap, and
install the matching case piece in its place.
2. Install the standoffs and MAFD 2hp using the screws with the standoffs. Avoid touching
the insides of the MAFD--static discharge can break it. Notice that the power jack on the
bottom side of the MAFD 2hp goes in the hole on the wooden support piece.
3. Install the final wooden case piece with the two included screws. Don’t overtighten. In
case the screws get mixed up, the two screws for this step are a little longer (8mm) than
the four (6mm) screws used in the standoffs.
4. Plug the right angled micro-USB jack into the bottom for power with the included power
brick.
