      Fantastic, all unlocked, this is going to be one hefty piece of kit in my set up � Nice one MD for pushing it over the finish line, I think DivKid should get a big � up as it was a bit static at 10K to go before his push and write up ��

      Ok. ThruZero getting close. If not reached with one day left, can't we all just pledge an additional $5 or so each to secure it? Would be nice!

      Fourthing Scala Support.

      Thirding the scala support.

      Seconding the request for user defined scales for the chord mode. The operation is fairly simple:
      1. Load standard Scala *.scl format scale files from the microSD card, in a folder named "Scales."The file contains the ratios or frequencies for every scale degree, with any number of notes per scale.
      2. Allow user to enter the "octave" (may not be 2/1 repeating such as for a Bohlen-Pierce scale, but the concept is still applicable) and scale degree (note) for each chord value.

      Chords Idea: Each new input cycles thru each osc (like Korg Monopoly Poly Arpeggiator)

      Hi Paul,

      Congratulations on reaching this stretch goal!
      I would love something like Stas' idea and it would also be nice if you could control the chord inversions somehow.

      With the floating assignments and now chord goals unlocked, is the idea that MOD A and B will have global settings so that MOD A c on Osc1 can be set to global mode and change all 4 oscillators at once, thus freeing up additional mod inputs for chord settings? Or will the chord settings be done by remapping the 1v/Oct inputs as chord modulation?

      I would love chords mode to support user-defined ratios (not just 12TET steps). This would be useful for xenharmonic compositon or for using it as a single-voice monster additive VCO. Here's how I see it working:

      1. Each chord is defined as as 1-3 ratios (i.e. VCO3&VCO4 may be excluded from chords if their ratios are not set, so they are individually addressable as usual)

      2. User can setup list of chords (i.e. up to 10 chords)

      3. CV1 is used to select chord root

      4. CV2 or coarse2 knob is used to select chord index in chords list

      Ideally there would be chord import/export to SD card.

      Another enhancement would be an option to morph chords, i.e. use CV2 value to interpolate between chord ratios.

      One earlybird now available- i upgraded to 2x

      Patrick Link on February 22, 2017

      I've upgraded from an EarlyBird slot to a 2x Early Bird, thereby freeing up 1 Early Bird (you're welcome whomever you are). I'd really like to see that Thru-Zero stretch goal reached!

      Certainly, if the CHORDS option funds, we will be asking for inputs to what people want it to do, exactly. Please post any ideas like this here.

    19. Damien Higdon on February 21, 2017

      The Chords mode brings a few things to mind. Would it be possible to allow the system VCO setting to include an additional 3+1 (triad, solo) configuration, while also allowing Chord mode to be a selectable option for triads (and pairs), so we can effectively have 3-note chords play while leaving the 4th VCO for solo/lead, and assignable to a different oscillator type?

      Gah. Previous comment should say:

      This would NOT be the first time Paul was responsible for people expanding their setup and getting new cases.

      Heh. This would be the first time Paul was responsible for people expanding their setup and getting new cases.

    22. LoydB on February 21, 2017

      I give up. I've backed it, knowing full well I don't have space for it :) New case time!

    23. Paul Schreiber Creator on February 19, 2017

      That's a great idea! Added to list of feature requests.

    24. Guido Heye on February 19, 2017

      Hey Paul, if there's room on the flash, you should maybe include a list of pledgers, would be cool!

    25. Paul Schreiber Creator on February 18, 2017

      Eric & I talked and we will be able to "tune in" voltages from about 0.95V/OCT to 1.25V/OCT. So, you are all set!

    26. Paul Schreiber Creator on February 18, 2017

      We will see how much work is needed to add 1.2V/Oct tracking as an option.

    27. Patrick McMaster on February 18, 2017

      Congratulations Paul - would it be possible to add support for 1.2V/OCT tracking in the firmware for all of the Buchla folks? Thanks!

    28. Paul Schreiber Creator on February 17, 2017

      Yes, the only thing to remember is each VCO has 1 audio output (unlike the E340 that has 2).

      But yes, 32 VCOs all going at the same time.

    29. Syruss Flyte on February 17, 2017

      So, if I'm reading correctly, I could set each of the 4 VCOs to cloud, with up to 8 virtual VCO's per cloud?... So effectively it can function as 4 E340's ?!? Can we say 'drone-y, ambient, awesomeness"? I mean, I was already sold, and backed before bothering to read everything, but now I'm even more excited about this project… except that I'm going to need another eurorack case now.
