receiving a clock over the Clock Bus. The
RCD
and
SCM Plus
can receive only.
Modules from other
manufacturers that send Clock Bus are also likely to be compatible, such as the Malekko Varigate 8+.
On the back of the
MiniPEG
is a jumper to enable sending or receiving clocks over the Clock Bus.
When this jumper is installed in the RECV position, clock pulses on the Clock Bus will be sent to the
Ping
jack as if they were patched directly into the jack. When a cable is plugged into the
Ping
jack, the
Clock Bus signal will be ignored.
When this jumper is installed in the SEND position, the ping clock (before division or multiplication) will
be sent over the Clock Bus. In other words, if you tap a tempo on the
Ping
button or if you patch an
external clock into the
Ping
jack, this tempo will be sent 1:1 to the Clock Bus. Changing the
Div/Mult
amount will not change the signal on the Clock Bus. When using the
Mini PEG
to send a clock, you
must ensure there are no other modules configured to send a clock over the same Clock Bus. Having
two modules send clocks on the same Clock Bus will result in unpredictable behavior, possibly causing
erratic tempos and/or making all Clock Bus modules fail to work properly.
To disable use of the Clock Bus, remove the jumper entirely. It’s safe to “park” the jumper by installing it
on only one pin.
Updating Firmware
The
Mini PEG
has a boot loader that allows for updating the firmware by playing a special audio file
into the module. When a firmware update is available, it will be posted on 4mscompany.com as a WAV
file (or zipped WAV file).
Updating Firmware
1. Download the audio firmware file and prepare to play it on your computer or mobile device.
2. Set your computer or device volume to maximum, both in the system/OS controls and also in the
audio player application.
3. Power off the
Mini PEG
and unpatch all cables.
4. Patch the computer/device output to the
Shape CV
jack (any mono or stereo cable will work).
• Note: If you have a 4ms
Listen IO
or other module that boosts line level to Eurorack level, run
the audio through it before patching into the
Shape CV
jack.
5. Hold down
Ping
and
Cycle
while you power on the
Mini PEG
.
6. The module will boot into bootloader mode, with the
Ping
light blinking green, and the
ENV OUT
and
5V ENV
lights purple.
• If you wish to exit bootloader mode, press the
Ping
button while it’s flashing green.
7. Begin playing the audio firmware file. You can monitor the signal by listening to the
EOF
jack.
• The
Ping
and
Cycle
buttons will alternate blue and white to indicate the signal is being received
8. If the update fails, the buttons will flash red. Press
Ping
to try again.
• If it fails more than once, you may need to adjust the threshold. See below.
9. When the update succeeds, the lights will flash rainbow colors. Press
Ping
to start running the new
firmware.
Adjusting the Threshold
The
Mini PEG
can compensate for a variety of signal levels by adjusting the threshold. This technique
is only recommended if you don’t have access to a line-to-Eurorack level conversion module such as
the
Listen IO
.
