Finally had time to come back to this. I'm still struggling to get my v1 working. meldano kindly sent me a new controller, which I installed following all precautions.
The muses chip seems to start-up at power-up (resistance between input and output drops from 200k to ca. 20k), but turning the encoder doesn't do anything nor can I program the infrared remote control. So, at this point I'm wondering if my encoder is broken?? (https://www.mouser.co.uk/ProductDet...vUC/3abYfYw==&countrycode=GB¤cycode=GBP)
Any ideas?

!!!Updated documentation!!!

In some cases the controller don’t wake up from sleep mode by rotate the encoder.
I updated the documentation (have a look the the first post in the thread).
It is possible to solve the problem:
a) with two pull up resistors (500k-1M)
b) update the firmware
ba) buy a st-link v2 clone and contact me. I will flash the new firmware with TeamViewer. You’ll need a windows 7/10 PC with USB

bb) contact me and send the controller back. I will flash the new firmware

Hi @meldano,
I’ll be starting my build in short order. Does the micro need to be programmed prior to installation (I bought the micro preprogrammed from you), or can it be programmed in circuit? Presume one of the board headers is connected to the programming ports (he asked before reading the schematics)?
Also, are the choices one or the other, or are all steps required?
Thanks,
Chris

Hi Alan,
J40,41 should jumped, when you use a 5VDC supply for the relay circuit instead a AC supply.

Hi.
Congratulations on a very fine kit. You mentioned the soft-step earlier. This can be controlled using a separate clock but you have decided to ground this input (pin17 CLK_IN). Do you enable this function using the internal clock? Are there any benefits using an external clock for this? Can you say something about the sound difference with the function on and off?
Best, Armand

@Chris: Very professional!
@Armand: Thanks!
It is possible to use the soft step with the muses internal clock.
I discarded the function, because the muses react with a huge short volume drop after initialization with the soft step function.
In case of soft step, it is necessary to use a mute relay to avoid this volume jump.
But the kit can also be use without the main board.
I didn’t hear any difference between soft step enabled or disabled.

Muses and STM chip availability
Hello All,
I just jumped into this project and was disappointed to find that both the Muses and STM microcontroller chips are not in stock in Europe (not at Mouser either). STM chip does not even have a lead time.
Any hints where I can find these items?
Thanks in advance,
Mike
