    I just wanted to thank you for your work in developing the 2500 modules for Behringer. They are wonderful sounding and well designed. I love them!

    Great design work. I have two of them.
    Wishes, wishes..
    I wish that the 8 input were normalized at 10 volts.
    Way more handy for using it as a sequencer or CV shaper.
    I wish that that you could get that nice clock signal.
    I wish that there was a second connector to allow chaining multiple 1050s to a 1027 sequencer.
    Lastly, ARP got the color of the knobs wrong.
    On the 1027, it’s grey, then green, then gold.
    The 1050 should have the green knobs first.
    I am grateful, but pedantic.

      Many thanks for the positive feedback. The 1050 was a completely new design that was done in CMOS rather than TTL. I alway expected it to be used for audio signals but the normalisation to 10v is a good idea but really needs an on/off switch to select between audio and cv mode.otherwise you could dump voltages into audio module inputs.

      The clock out was a victim of panel space..the chaining is easy, just create a ribbon cable with sockets on it rather than headers, then plug as many in as possible! You can always swap the knobs around!

      I hope this design lasts a long time as the original TTL circuit is now impossible to recreate as the 1960’s chips it uses are long since obsolete and dead.

  • Yes very interesting module and great its abailable for more people. Thx

    I noticed a Yt video were the 1050 was used as suboscillator. How does that work?

    Kind regards!
    Ps Will there be a Dss-1 njm filter module?

      Patch a square wave into input 1 and the external advance, then set seq length to 2, maybe that does it.
      2069 chips have become very rare and there are no clones, so unfortunately no plans to do the AM8069 module.

  • Thanks again for your help with the expansion port.
    I ended up using CMOS buffers for safety but a simple connection would have worked.
    Should have used Schmitt triggers though.
    It’s just 2hp 8 sockets and the plug in sockets extent under the 1050.
