Connect the Two PCBs
Visually inspect the panel PCB, checking for bad solder joints or connections that you
might have missed. When you’re confident that your work is flawless, fit the main PCB
and panel PCB together and install the standoffs. Check the trim points shown above
and make sure that the leads won’t make contact with the capacitors on the main PCB.
Panel Installation
The final step is to install the panel. Remove the protective plastic layer first, then fit
the panel onto the hardware. Now install the nuts onto the jacks (the slot on the nut
faces outwards). For tightening the nuts, we recommend using a small pair of flat-
nosed pliers with tape on the ends to avoid scratching the panel.
Power Up
With the module powered on, check to make sure each of the LED switches
illuminates when pressed. All switches are momentary so one press will turn them on,
another press will turn them off.
Holding the LOOP/END, SEQ/RAND, or GATE/TRIG switch for 1 second and then
releasing it will cause that switch to flash. The 1-8 switches will then be used for
changing the module settings. With LOOP/END flashing, the 1-8 switches set the
overall sequence length, from a maximum of 8 steps to a maximum of 64 steps. With
SEQ/RAND flashing, the individual pattern length can be set, with a range of 1-8
steps. With GATE/TRIG flashing, each of the 1-8 outputs can be programmed to send
a gate signal matching the input clock pulse width (LED is on) or a 10ms trigger (LED is
off). Press any of the three switches above to exit these custom settings modes.
Now check each of the input and output jacks to make sure that they are sending or
receiving logic signals. The inputs are all on the bottom row, with black circles around
them. STATE turns playback on or off. RESET restarts the sequence at step 1. CLOCK
is the clock input, and MODE toggles between sequential and random playback. The
outputs are the 1-8 jacks and the Start, Stop, Clock, and Pattern jacks. Consult the
Algorhythm manual for a complete explanation of their functions.
If everything checks out, then congratulations: you just built your own Algorhythm!
