An earlier post mentioned a max delay time of 50ms when in Chorus mode. In comparison, the MF-104z had a max delay time of around 1000ms. The use of high voltage BBDs in the 108M is perhaps for better signal quality. The 50ms max delay line time might seem to indicate fewer steps in the BBDs, but who knows how it is actually clocked. At any rate, they are probably fairly distinctly different effects. It would be interesting to compare the effects of various modulation sources on each delay circuit.
Hey EricK! And Toryjames, and anyone else reading…
Just FYI: I do still have the prototype chorus/flange and I do intend to post a video of it. I have meant to for what is now literally almost the last year!! A little university will do that to ya. Anyway, with this very exciting recent product announcement, what better time to get off my rusty dusty and finish that project I started back in August of what is now, already last year? 
Audio/video clips soon of prototype Moog. Sorry for delay. I am really interested to compare them side by side now… 
Where is the MF-108 app?
Finally got mine here in the UK! It’s been quite a wait!
I’m absolutely blown away. I’m a bassist who plays live Drum & Bass, Dubstep and Electronica and this is amazing. I’m pretty certain this has just replaced 4 other units on my board. As a classic Chorus or Flanger its thick and lush - but open up the delay and feedback and with octave and fuzz before it what you have are huge synth swells. Sync’d to midi clock, flanger on high speed, sample & hold = effective sequencer!
This really does it all.
I’m aiming to record some sound bites and video as part of my set up this week so watch this space.
