The challenge: fit everything you really want from a bass synth into a 4″ x 4″ square. Make every parameter hands-on, with full-sized knobs and switches. Give it an analog filter that can be angry, not just nice.

Our solution: MeeBlip anode. It’s the new collaboration between CDM and instrument designer James Grahame. Together with James’ engineering work, we’ve cooked up a little package that focuses on packing personality:

  • Digital oscillators meet an original analog filter
  • Grungy, bass-heavy sounds
  • Compact, 4” x 4” case (approx. 100 x 100 mm)
  • Modulation, envelope, tuning, and pulse width controls
  • MIDI input for compatibility with vintage and modern hardware, computers, and (with a compatible adapter) iPad and iPhone

And here’s what anode sounds like – completely unprocessed, recorded straight out of the anode’s audio jack (more sounds to come):

Price: US$129.95 / 129,95€ / £109.95

From now through December 3, though, you can it at a special Thanksgiving discount for presale customers:

US$109.95 / 109,95€ / £94.95

anode v2.65

Presale means these are built to order – we are able to more quickly scale up volume of case manufacture – and shipped to you as quickly as we can after final assembly and testing in Canada. (ETA from now: 7 weeks.)

anode is our biggest release since the original MeeBlip three years ago. It’s been a constant reminder of why I want to be making hardware as well as writing about it. We can’t wait to get it in your hands.

And I know we’re likewise eager to answer your questions and comments – please, ask away. Having seen some discussion online, I’ll already say this:

Hell, yes, digital. MeeBlip has always been about straight-to-the-metal digital coding. The variable-pulse-wave oscillators on anode alias at the low end for extra grunge, with anti-aliasing higher for more versatility on melodies. So, we still have digital oscillators – newly tuned for sound that’s like MeeBlip, but better.

Hell, yes, analog. For anode, James Grahame devised a new analog filter. It’s a departure from most of the KORG MS-style or transistor/diode filters currently popular on the market. It still behaves like a classic low-pass in use, but it sounds aggressive, especially as you add resonance. We wanted to make sure there was no part of the filter range that felt boring or conservative; that’s not what this instrument is about.

Simple, playable. Each knob, each switch, each range has been carefully considered (sometimes, hotly debated) to result in anode. You get hands-on control, plus a MIDI message corresponding to each parameter for automation (with the exception of analog filter resonance).

Hackable. anode is designed with the assumption that many players won’t change a thing. But if you do, we’ve made it easier to modify both firmware and software. Component swaps can transform that sound of the filter; you can add features you want like audio in or CV in if you really want. We’re also busily finishing the next-generation MeeBlip micro board, a pre-assembled board that you can easily build into your own projects, so we aren’t ignoring DIYers. MeeBlips are now all assembled projects, but if you want to solder and construct and write code, you can build on what they give you.

And yes, it’s still open source hardwareThe New MeeBlip anode @ MeeBlip blog

    This looks (and sounds) like a lot of fun.

  • Dream Hike

    Ordering today. Great work.

  • JF

    Sounds really good! Will be a nice companion for my MTRX-8!

  • Bodo Peeters

    Next step MeeBlip Eurorack? Pretty please?

    • Peter Kirn

      It’s an interesting idea. Shawn Rudiman has already built a CV-enabled rack using MeeBlip micro – part of why we’re eager to get the micro back on sale!

  • Armando C

    Perfect companion to my OP-1. Thanks!!! :)

  • Martin

    is there a way to do poly chaining?

    • Peter Kirn

      Not directly, but there is a MIDI channel select button, so if you have a thru box, you could use up to four anodes. :)

    • Martin


    • Joshua Schnable

      And, if you have said thru box, here’s a site with a free VST that can split the MIDI for you:

    • Peter Kirn

      Wow! Those are excellent.

      A shame Renoise doesn’t support them, though I suppose it has some of its own tools / scripting.

      Cubase, Reaper, Studio One win again. 😉 (seriously, the routine answer to “why can’t I do this in my DAW” with those three is “we can”)

    Hi Peter,

    “Price: US$129.95 / 129,95€ / £109.95

    From now through December 3, though, you can it at a special Thanksgiving discount for presale customers:

    US$109.95 / 129,95€ / £109.95”

    -> The discount is only for US customers?

    • Peter Kirn

      Yipes! No, correction:

      USA: $109.95 ($20 off)
      EU (minus UK): 109,95€ (20€ off) … includes VAT
      UK: €94,95 (£15 off) … includes VAT

      You’ll see those discounts when you enter code “THANKSGIVING” on checkout. (Thought it sounded nicer and happier than “Black Friday” or “Cyber Monday.” We’re thankful!)

      Also, we have lower shipping rates than before – $/€/£ 10 to USA, Canada, EU, UK, flat.

      If you live outside the USA, EU, or UK, you still get a discount. You pay in USD – $109.95 ($20 off). The only difference is, shipping is $20 and we don’t include a power adapter (in order to keep that shipping rate low). You may also be obligated to pay customs when your MeeBlip enters your country.

      Sorry, you copy and paste this too many times and your eyes start to glaze over!

    • Gwydion

      Cheers, thanks for the clarification.

  • aaron

    Looks nice and crazy affordable, portamento/glide would have been a good touch.

    • Peter Kirn

      Glide is accessible by MIDI CC – it’s CC 55. We’ll actually be sending a card to our preorder customers to thank them, and it has a MIDI CC chart printed on it.

    • Aaron

      nice, good to know it’s got it. maybe post those online?

  • Freeks

    When the new pre-assembled Micro comes to sale? I still haven’t got my self-assembled micro to work. Have the case, knobs and such ready.

    • Peter Kirn

      As fast as we can. We’ll announce a date once we’re confident of manufacturing deadlines, etc.

      But if you’re having trouble with your micro, get in touch on the forum:

  • sinfm

    Purchased! :-)

    • Peter Kirn

      Thanks! :)

  • Rayk

    with that analog filter onboard an audio input would have been nice
