  1. Bonjour, je viens de passer une commande ebay pour un Attenuverter.
    J’aimerais en avoir d’autres, est-ce que vous en avez d’autres de disponibles à la vente?
    Je vous pourrais vous payer directement par PayPal pour éviter l’addition des frais de poste.

  2. Bonjour,
    j’aimerais vous acheter une petite alimentation et un power bus, pouvez-vous me recontacter par mail ?


  3. Is there a panel available for your simple lfo? If so, do you offer a kit with one included. Perhaps a fully assembled version?

  4. Hi David

    I would like to buy four LFO PCBs, but you’re out of stock at Tindie. Any chance of a restock?



  5. I would love to purchase one MFOS SLMS Euro PCB and one panel if you have any left.
    If there is no PCB, then I will not be purchasing a panel.

  6. Hello David !

    I bought last years some of your items on Tindie; now I Would really enjoy to purchase one MFOS Euro PCB and – if there is one left – one panel.

    Kind regards

  7. Hi David

    I hope you’re doing well.
    I recently found out about your awesome work on synth modules.
    I would love to get started with one of your projects.

    I am specially interested in the MFOS SLMS.

    If I’m not mistaken, you have the PCB in stock, but it is still in prototype phase.

    Can you please elaborate if there are future versions planned and whether there will be any big improvements in the next revision that are worth waiting for?

    Thank you so much for your reply.


    1. Hello Faye!

      The MFOS SLMS version 1.4 is final. No further modifications planned in the future.
      The PCBs I have in stock are the prototype runs.
      The official SLMS (the version 1.4) should be sold by Synthcube any time soon.

      So, I have the 1.4, the 1.3 and the 1.2 in stock.
      The differences are as follow:

      • removed Regulators 78L09 and 79L09 due to availability issues
      • added decoupling capacitors
      • added Hi Freq trimmers for VCOs


      • modified Sync circuitry, according to PLUS
      • improved White Noise generator

      The next project is the SLMS PLUS, which is the upgrade suggested by Ray, minus the Sample and Hold. It is a different form factor. More CV inputs for example. The PLUS is not yet ready.

      I offer the 1.2 and 1.3 plus the Sync Mod Board, with a discount.

      1. Hi David,
        Thanks a lot for your quick and detailed response.
        I’m very happy to hear that you are working on the SLMS PLUS. Before I found out about your projects, I was close to start building the regular PLUS version. So if there will be a Eurorack version from you in the future, I’ll gladly wait for it.

        What about the WSG? Is the current version the final one? Are there any PCB available to buy?


  8. Hi David,

    I’d like to buy two LFO PCBs but they’re out of stock on tindie. Will you have them in stock anytime soon?

    Cheers from Germany,


  9. Hi David,

    Great work on the MFOS SLMS!
    Looks like a great project for me and my son to work on. Would be happy to help you get rid of your backlog PCBs. What do you have available now and how do I purchase?


  10. Hello! I built a couple of MFOS SLMS 13-15 years ago because I could not afford a synth and now I see this I feel like building again! big urge to find a pcb! ideally the MFOS SLMS Euro PCB v1.4 or whatever! please = )
