ATTENTION

Due to the non-commercial nature of the licence there will be no more KITs from me, sorry.

Description kept for Reference...

I used an assembly service (JLCPCB). They do not have all the nerdy parts used by this project. So some chips and caps and THD parts still have to be soldered.

Watch my build and test run... see below!

What makes it special?

My PCB Modifications:

• Use of PJ-301M jacks, with the pin like pins. Included with this kit.
• I also added polarity change jumpers for the MIDI in and out jacks, so you can used it with Korg or other (Arturia/Novation...) gear.

This verion is commited there: GitHub

Difficulti Level

Advanced 4/5 - need to solder SMD parts.

Be aware of:

• You need additional parts for ~ 120€ from my mouser part list.
• The SD Card Holder (not available in EU? thonk.co.uk has it) ... is included with this kit.
• You need to program the thing, this requires a serial adapter like this OR a JTAG programmer with a 2x10 1.27mm Pinheader connector programmer and this adapter 20/10 ??? - these are not included.
• Please consider a donation to the westlicht guys, ongoing development of such a well made and fluent software takes a lot of effort.

What you got

• Main PCB (with ~80% soldered components)
• Front Panel (black PCB)
• 24x PJ-301M jacks mono
• 2x PJ-301x jacks stereo (for the MIDI on the top left)
• 1x MicroSD-Card Holder
• 1x Encoder Knob "soft touch"
• 1x 6x1 Pinheader female - for uses with the Serial programmer.

Tips

Assembly:

Follow the westlich build guide. There is a very handy Interactive BOM, which helps in locating the parts on the board.

Parts:

• My Mouser Project contains the DAC8568-A you can also get the "C" version there, this must be considered when choosing the software.
• Mouser has the OLED display in different colors. Mouser search.
• Alternative Button caps Mouser search... in case you want other colors or some are not in stock.

Programming the firmware:

There are many ways of doing it, I describe the one with the above mentioned USB-Serial adapter and use the STMCubeProgrammer under Windows.

• Get bootloader.hex, sequencer.hex and hwconfig_dac8568a.hex from Github..Releases
• Install STMCubeProg and open it.
• at the right select UART from the dropdown and the COM port which belongs to it. (You can find the port in the Device Manager) I also set speed to 115200 and parity to none,
• Power the performer, press reset and boot buttons (the 2 flat smd buttons) together then release reset, hold boot for 3sec or so. Then in the STMCubeProgrammer, press connect, the device info should appear in the lower right.
• at the top left, load one/all of the hex files you got from the westlicht github.
• for each file tab, press the download button (within the tab to the right). That should burn the firmware to the performer.
