<div dir="auto">Hi JP<div dir="auto"><br></div><div dir="auto">A few suggestions might be:</div><div dir="auto"><br></div><div dir="auto">1. Design 3U & 5U modules to take the new submodules you design.</div><div dir="auto">I see from your previous work that you have a MU system so it would be cool to see Moog-style ARP modules.</div><div dir="auto"><br></div><div dir="auto">2. Rather than aim for 100% clones, maybe implement the new filters as close as possible in SMD and productionise them. This would be good future-proofing but I accept the point that you may not wish to compromise the ARP design integrity with changes.</div><div dir="auto"><br></div><div dir="auto">3. Create the designs in KiCAD and open-source the design files.</div><div dir="auto">I see CERN have open-sourced their component libraries so creation of the design with KiCAD could be made easier by this:</div><div dir="auto"><a href="https://hackaday.com/2026/05/12/another-gift-to-the-world-from-cern-their-entire-set-of-kicad-libraries/">https://hackaday.com/2026/05/12/another-gift-to-the-world-from-cern-their-entire-set-of-kicad-libraries/</a></div><div dir="auto"><br></div><div dir="auto">Just a few thoughts</div><div dir="auto"><br></div><div dir="auto">I look forward to hearing about your progress with this.</div><div dir="auto"><br></div><div dir="auto">Best wishes</div><div dir="auto"><br></div><div dir="auto">Gerry</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Fri, 15 May 2026, 14:41 Jean-Pierre Desrochers via Synth-diy, <<a href="mailto:synth-diy@synth-diy.org">synth-diy@synth-diy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="FR-CA" link="#0563C1" vlink="#954F72" style="word-wrap:break-word"><div class="m_-46638807501131799WordSection1"><p class="MsoNormal"><span lang="EN-CA">Hi list,<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-CA"><u></u> <u></u></span></p><p class="MsoNormal"><span lang="EN-CA">I’m thinking about making some ARP’s VCF modules replicas for sale.<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-CA">All the same components and PCB arrangements.<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-CA">Completely the same as the originals..<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-CA">But I’m wondering which one(s) would be the best candidate(s)<u></u><u></u></span></p><p class="MsoNormal"><span lang="EN-CA">or should I say ‘looked for’.
