This is a quite straightforward build, as all surface mount components come pre soldered, however the layout is pretty tight so care has to be taken to avoid melting the plastic on the headers when soldering the through hole components.
Do this before building this module:
Check that you have all components.
Gather all the tools needed (see lists below).
The tools needed for this build are:
Soldering station or soldering iron.
High quality solder (lead free recommended).
Fine tipped side cutters.
PCB holder (makes life much easier).
Knurled Nut Driver Tool (for tightening jack socket nuts).
10 mm and 11 mm hex sockets covered in masking tape (for tightening nuts).
Got everything? Let’s get on with it!
3. Potentiometer, switches and jacks
5. Finishing up
6. Powering up and testing
Before powering on, measure resistance with a multimeter between ground and + and – respectively on the power connector to make sure there are no short circuits. The resistance should be several kilo Ohms and the value should climb as the multimeter charges the capacitors.
At first power on, hold the MODE and RECORD switches for a couple of seconds until the red RECORD LED blinks. This is for initialising the sequencer memory.
Connect a CV/GATE keyboard to the CV/GATE inputs. Press RECORD and play some notes. Now press PLAY and your sequence should play back if you have a synth voice connected to any of the CV/GATE outputs. Note that when recording sequences, the notes are only monitored on CH1. Have fun with your new sequencer!
