    I came across this site in a Google search. I’m interested in a JP04 oscillator and JP04 filter. Is any this actually available to buy?

      Hi
      The JP04 VCO and VCF are in development and will be launched around April time

    Remarked (or refurbished) BA6110 on your photo.

    We made clones of the LM13700. I know you are going to say “well that’s easy”, but we did a lot of research and select the clones on our dedicated tester, just like Roland did. So, we can supply clones that fit at least on 90% of the positions the original BA662 needs to replaced.

      Thanks for the info, great idea! I may well need an accurate BA662 clone if the ones in my JP4 Voice Card have failed. Rob

    Regarding the SMT BA662 pinout, there seems to be one extra functional pin compared to the SIP component. An extra buffer control input? If one were to adapt the SMT chip to replace the through hole part, how would this extra pin be best handled? Tied to the other control input? Tied to negative power rail? Left floating?

    I was planning to leave floating and see how it performs
