My Christmas present from my belovèd (my request, of course). More details here.

Board looks cramped at first sight but doable if one manoeuvres it to accommodate the iron with due care. They provided a full set of leaf sockets for the ICs, which I replaced with better quality precision DIL sockets. I've had too many bummers with leaf sockets to trust them in such a build FWIW.

They only supply kits for this range but well and good because it has some obscure (at least to me) parts: the cherry keys and 1.8mm LEDs (white button assemblies in last pic). Not exactly a snip at 110 Euros, but I had some good luck with customs who cleared the parcel as an ordinary letter, hence very low duty fees.

I assembled the whole kit and kaboodle and found voice 1 not functioning. After the initial ice-cold feelings of frustration and self-doubt, I inspected the board with more care and found that I'd been over-miserly with solder on two switch connections in that part of the circuit. Retouched these and problem solved.

This shot exposes my somewhat grubby finger marks but it looks fine in the rack.

While awaiting its arrival, I read the manual very carefully and must say that I learnt a lot from the designer Moritz Klein's copious explanatory notes. I've been wanting to run an analogue 808-based drum machine setup for a long time and this doesn't disappoint. As MK himself says, the modulation possibilities (two LFOs and CV out from each of the four voices) give it an 'organic' feel. With four different gates and CVs available, one could even use it as a melodic sequencer for tuned percussion or whatever strikes one's fancy.

Hugely relieved in the end that all functions as intended.

Thanks for reading as always and wishing you every joy with your projects.
