Wee update!
  1. hardware is very nearly frozen for production. Doing what should be final schematic and board reviews.
  2. artist preview prototypes arrived with a couple of content creators. Lots of video/audio stuff to come once production milestone is hit.
For now, here's a new 2h long livestream with Mindphaser on bassline duties.

Any updates here? :D I'm excited for more videos!

There was a update on their instagram.. just stating another 'final' panel design. :0

Very curious to see how this sounds compared to Frap Brenso, hopefully won't be long.

That wouldn't be the so off the mark for some. Filename management is a thing

Pretty much! The more "final"s I add the more likely it will seal the deal :cloud:

Coordinating the versioning between panel, sch/PCB and firmware has been the most annoying part.

Hey all! Current state of things!

dev/production updates
- final design-for-manufacture changes done, as mentioned last update. Production candidate PCBs and parts are ordered, just waiting on those. Everything is running slower, post-COVID.
- final tweaks to panel design made. Had to deal with some possible mechanical interference on parts behind the panel which could surface when going into production. Those have been ordered to verify all is 100% (as seen in Instagram post someone kindly linked, hehe)

As soon as those pieces come together, production planning begins. Should be a matter of weeks from now to verify the hardware. :party:
Would hope to have some news around August in terms of an idea when it is going to finally come about. Maybe sooner, or later. I'm being loosey-goosey until I can say stuff for sure.

videos

Dash Glitch has been jamming away in his corner of the YouTubes with it in more streams, since he's one of a couple of people with a preview prototype racked. Here's a gooder since that last one quoted. Doing more mid/lead-y alien sounds with it:



He's doing a ~30 minute introduction, exploration and walkthrough of the module, coming from the perspective of someone who is moderately fresh to complex signal generators/VCOs, and was given no user manual or anything to work from. That one should be coming out in the not-too-distant future.

Will be doing in-house as well, and the other usual suspects more than likely will turn out some videos. I've just been swamped with all the things and should have more room to breathe once manufacturing kicks off.

I knew it! LOL - I'd love to see what the "last" file name ends up being before it hits production!

I've been stalking his YouTube for a while now! After the first video he did with it, I subscribed and get notifications for his uploads now 8-) I wandered away from the idea of a complex osc for a while, but hearing the sound demos of his patching made me fall in love with the Mindphaser sound again.

I'm excited to see that 30 minute video from him, it'll be the first "full" complex osc module I get. Would love to see Loopop get his hands on one of these, his video walkthroughs are incredibly thorough for breaking down complex things.

Is this thing a thing yet?

Will there be a preorder when it is a thing or will there be a mad dash when it becomes a thing?

Very close :hihi: not in shelves yet though!

The hardware design has been complete for awhile (as you may or may not have surmised from recent small updates).

It's just been getting little bits massaged into place on the double sided SMD, 6 layer PCB to make it suitable for mass production.

Verification hardware is being/has been run on the pick and place and selective solder machines this week.
Sounds like the small lot of units should be built up and shipped over to me pretty soon!

If all checks pass on those, then there's nothing left to do on the hardware/design-for-manufacture end of things and we can start planning to build full quantity and do all the other stuff that comes with that phase of things.

So. Still not a date to say yet. But could be late summer/early fall (for these northern regions I mean) if all goes to plan.

There will more than likely be a preordering option available yes! Will have more details when it's time for that (ie not until all of the ducks are very much in a row).

Ah cool, awesome! I think he was in the same boat when he received the Mindphaser to do the video with - in terms of it being the first full analog complex signal generator in his setup. Should be a good one.

Loopop has some nice videos. Not sure we've been in touch though, so I'm not certain one will get in front of them for review.

Excellent! Preordering will definitely be a welcome option.

Glad to hear things are progressing nicely.

I am ready to throw down on this NOW!
Really impressive demos on their Instagram.
I’ve tried a few complex oscillators, none i completely gelled with. And none of the frap tools one’s demos really grabbed me. Really hopeful for this one though judging from most of what I’ve heard so far and the feature set.
Should pair nice with natural gate too!

Will be keeping my eye out for that pre order!

Question though, why no sine wave out on the second oscillator? Is that sine normalized to the folding/shaping section?

Edit- nevermind I see the sine/saw wave selection for the shaper now.

I'm interested to hear how the TZFM was implemented in this vco. After learning abut the different was it can/cant be achieved in this thread really curious to see how they did it. It's interesting that there is no symmetry control, which is found on most TZFM vcos.

Its not a tzfm oscillator just a regular lin/exp fm one, so it wont have a symmetry control

its got a through zero phase modulation bus and i assume thats similar to the well known phase modulation circuit thats in the FMaid By happy nerding or the Sinulator by West oakland synthesis. Where a saw wave pushes the other wave through a wavefolder type circuit, that essentially exactly replicates digital Phase modulation.

Hang tight for the proper technical manual/sheet describing things to clarify some more -- but yes, in essence!

The wavefolder has two modes: triangular, and rampoid (not "sine or saw" -- just to avoid any confusion, there).

Both modes make sines as a base waveshape, when the folder is turned to minimum. The difference is in the way that it progresses through folds on those sines.

Exactamungo!

Mindphaser's wavefolder design is based on principles in the Gilbert paper, yes. The Sinulator is based on the same paper, as well.

Right, yes. It's kind of an "analog phase accumulator". Phase accumulator in the digital FM/PM synthesis type of sense (where in software the principle could be to use a phase accumulator to generate sines from, and then modulate phase on top of it).

A phase accumulator is really just fancy nomenclature for a "ramp wave driven sinusoid generator", in the digital realm. You put a ramp in, and get a sine out. Modulate the ramp in different ways, and you modulate the sine coming out, too.

Which is exactly what Mindphaser's wavefolder does. No idea what's in the Happy Nerding but I wouldn't be surprised based on the description of it, if a similar concept is at hand.

Of course after the core principle is where these three diverge in terms of circuit and feature similarity in their wavefolders.

And yes, the FM to the two VCO cores are garden variety linear FM that is *not* thru-zero. It's the TZ-PM bus where you will find thru-zero action.

Hope that helps shed some light. There will be more detail in the proper tech documents/user manual when it's finally time to write and upload that! :tu:

Things are very much coming along - I've just received the verification hardware finally. Some unfortunately bad timing unrelated deadlines about to pass next week, and then I'll be wrapping up the last bits to take the next steps toward production.

I should have some real news in October. :sb:

Good news is, things are steaming along looking great right now.
Hardware verification has gone very well indeed, and will just need some final sanity checks before signing off on it.

Chatting with the production team shortly.

So the news is coming soon :cloud:
