Sequencer:
The sequencer is a very large part to assemble. Do not reverse the IC. Continue to be careful and precise we soon reach the end. Courage. Prepare components to build the sequencer. List of components:

Make it:
 | The components of the sequencer are outside the dotted line. |
 | Solder all resistors. Solder each value one after the other. |
 | Solder diodes 1N4148 MAKE SURE DIODES ARE IN THE RIGHT WAY |
 | Solder multilayers capacitors (in yellow on the picture) |
 | Solder the crystal
|
 | Assemble the two IC support.
|
 | Solder the three pushbuttons. |
 | Solder the 18 color pushbuttons. You can arrange the color as you like. They are a bit hard to implement but gently pressing it sinks without any problems. |
 | Prepare 6 LEDs and their supports. |
 | Solder the 6 leds being careful plated supports to the PCB CAUTION TO THE ORIENTATION OF LEDS. WELL PUT THE FLAT SIDE TO THE INDICATE SIDE BY SILKSCREEN! |
 | Solder the encoder |
 | To fix rotary switch to the PCB take four pieces of wire or bare copper and bend them the width of the Rotary switch (see picture). |
 | Assemble and solder rotary switch with clamp. |
 | Install the 74hc595 and 74hc165. Do not connect the power until the IO_Board is completly connected to the Main_Board because the ground of the sequencer is not common to the analog ground. Now to assemble the IO_Board |
