I sold some of the MOTM line to BrideChamber in 2008, and the rest to SynthCube in 2009.

 

In 2014, BrideChamber sold his portion to SynthCube.

Will and I are still here.  I was dead... briefly... a few years ago.  But my ticker started back up and viola!  Yup - we're still here.  And we've been cooking up mischief hanging out with Gino Wong.  5U dead?  God - I sure hope not.  May be expensive, but from a ergonomic point of view, it's a superior User Interface scale compared to smaller ones, at least in my opinion.  I mean - hey - there's a reason the old Bell Telephone chord-boards were this size.  Still here.

First of all, hi Aaron!  Long time...

Secondly, I think a lot of the MOTM discussion has gone to Facebook as well as Muffwiggler.

Thirdly, MOTM is surviving.  I sold my original system, bought Euro, bought used MOTM, am selling Euro, and keeping Frac and MOTM.

Fourth; does anyone have an MOTM-190 they'd like to sell?

Just finished constructing (and am now troubleshooting) the JH Living VCO’s (the RandomSource version). Need to design an MOTM front panel that includes all the RandomSource addons. Is there a MOTM grid/template for Front Panel Express floating around somewhere?

Meanwhile, did anyone ever make a Moog-style sequencer for MOTM format? I mean, there’s the Klee, but I want a boring ol’ Moog style one without having to modify a MU-format one…

Hi,

I'm still here too.
I build since 6 years my MOTM modules, I got the most pcbs and panels from bridechamber, since he closed his shop I order by synthcube.
Many pcbs was ordered from Tony (Oakleysound) and cgs.

I got a living VCO panel in MOTM from freestatefx, on my website are designs with waveshaper and other options, the original panel with vernierdials was copied from Bill and Will (http://www.dragonflyalley.com/synth/constructionJHLivingVCO.htm)

I’m still on this list also. I still have my MOTM system and prefer it in most (but not all) ways to Eurorack.

 

As some of you know, my company started making and selling Eurorack modules a couple of years ago. (I’ve had the pleasure of meeting a couple of people from this list in person at NAMM as a result.) I’ve always hoped that we would be able to offer large-format versions of our products once the hardware side of the business matured. Unfortunately there just doesn’t seem to be enough market demand to make it a sensible business decision.

Eric - 

Will and I designed just such a panel back in 2010 or therabouts. As soon as Jurgen emailed us about the VCO (in the way-back time) Will asked him what would be involved with adding waveshapers in the form of a daughterboard. He had some correspondence with MFOS about the idea of using the VCO module for its waveshapers. Here is that old page for reference:

http://www.dragonflyalley.com/synth/constructionJHLivingVCO.htm

We were, of course, very sad when JH left us all. My subsequent illness (a blood staff infection that nearly proved fatal) postponed our further exploration of and implementation of the module.

But then, as I was still recovering, a couple years ago, at Gino Wong's request, we did a review and even more careful analysis of Jurgen's Living VCO circuitry design including the modifications and improvements by the community at large. And we ended up helping with his issue of a modified version of Jurgen's PCB. The results of that process is documented here:

http://reredredsynth.com/ladbrokeGroveVCOarray-intro.htm

You can see as part of that effort, we outline the additional features to be provided in the daughterboard  envisioned by Will back in 2010. These are the features which later, subsequently appeared as part of the Randomsource PCB.

So - there is a fpd file on this page here:
http://reredredsynth.com/ladbrokeGroveVCOarray-implmt.htm

We have not ordered the panel so we can't vouch for its perfection. If you'd like to use the panel for the Randomsource version of the module, we (or you) can easily modify the name of the module at the bottom, of course. But if you wouldn't mind, Will and I would rather appriciate it if you leave the little dragonfly moniker intact.
If you want us to modify the fpd design for you, we'll do it happily.

It's so cool to have people posting stuff here. I've missed it.

I don’t go near Facebook (long story), but I probably spend too much time at Muff’s (mainly the 5U forum)

As an add on to Adam’s comment, I talked to the guys at Thonk last year about supplying PCB only options for some of their DIY offerings (it seems silly to me to buy a kit or panel kit and throw half of it in the bin) - they said it wasn’t worth it, because 5U for them is around 1% of their market

There is however a lot of stuff out there that’s 5U compatible so long as panels aren’t an issue
I feel a list coming on, as I’ve put a lot of DIY modules together in the last 18 months

Cheers
Paul

Re: [motm] Re: Is MOTM/5U dead???

2017-01-08 by Terje Winther

MOTM/5U is not dead by my account.
All my modulars (except the original digisound and Aries modular) har been worked into 5U format with 1/4" jacks. I have several modular cabinets in various formats (dot.com, custom wooden, rack etc.) with MOTM/5U format modules. Lots of synthesizers.com modules and moog 5U format modules, as well as many MOTM-format modules (mostly Oakley modules and DIY now). I perform live (mostly Berlin school sequencer stuff) and haul modular cabinets to gigs (just had the 15 years anniversary concert with my band), and the large modulars are essential.
Also; in the studio, I really like the big format. Suits my working style and fingers much more than those small things.

That said; I am not oblivious to the fact that large format modulars have fallen off in comparison to Eurorack format modules. I have run the Norwegian analog synth gathering for 10 years now, so I do notice the massive increase in Eurorack/Fracrack format, but I also notice this: a lot of people getting small format modulars tends to either
a) not have a clue as to what they are doing, and so...
b) sell off a lot of their stuff
c) mostly make unstructured blipp-blopp music

While in comparison most MOTM/5U users
a) really know their analog synths and how to patch up sounds
b) rarely sell their stuff
c) make (more or less) stuctural and/or tonal music

This is of course an oversimplification, as I have met Eurorack people with great music and huge knowledge, but what I said is really is a general tendicy.

I think the reason we (?) or most people think MOTM/5U is dead is this:
1) Some of the key players are less active now. Paul Schreiber used to be *very* active on mail lists and forums. He is still there, but a bit more subdued. So we are not sounding off all that much.
2) There is still a lot of MOTM/5U modules (I bought a few last year, and was amazed at how many new manufacturers there were - even some mostly Euro-rack manufacturers have started making MOTM/5U size modules) - but (and here I go): this increase on MOTM/5U is completely drowned out by the massive amount of new Eurorack modules flooing the marked!
3) And not to forget self-fullfilling prophesies: Everybody is saying 5U is dead, so it must be true.

But, yes; I have lived through many "format wars", and never in my life thought LP (that is vinyl for you youngsters) and cassetts would return, so who knows?






Re: [motm] Is MOTM/5U dead???

2017-01-08 by Richard Brewster

Not dead, just sleepy.  I still have most of my MOTM format modules, in dot com cases with rails from Larry Hendry.  I've sold a few, but the market has really fallen off.

I'm currently selling two DIY MOTM format modules (not Synthesis Technology), which are posted FS on Muff Wiggler.

Converted Mattson 4 channel gate delay.  $129 + $10 Shipping to U.S. address.

<http://pugix.com/synth/mattson-4-channel-gate-delay/>

Dual CGS Burst Generator $169 + $10 Shipping to U.S. address.

<http://pugix.com/synth/catgirl-synth-burst-generator/>

I got distracted by Eurorack over the past couple of years.  So many interesting modules available.  I did build a second MOTM conversion of George Mattson's 4-channel VC mixer last year.  I cross patch between MOTM, Euro, BugBrand, and Ciat-Lonbarde gear.  I have every conceivable adapter patch cord!

My Euro enthusiasm is slowing, partly due to funds, and partly to space.  I don't anticipate growing my MOTM system, but I do plan on still using it quite a bit going forward.

My main system is still 5U - mostly MOTM, with some MU.
Last year I made small company based on teaching DIY (aisynthesis) and those modules are all euro at the moment, but I do long to offer 5U and hope that 2017 is the year for it. I just need to find a good source for making the panels. 
MU seems to have a larger market than MOTM at the moment, but it's much harder to make the panels.

RE: [motm] Is MOTM/5U dead???

2017-01-08 by John L Rice

I’m not sure if you folks are asking about MU panels for DIY but if so, the options I know about:

 

Re:Synthesis in the UK are probably the number one source but they are swamped because pretty much everyone seems to be using them! They do panels in the same way as the original Moog panels.

http://www.bigbluewave.co.uk/resynthesis/resynthesis_home.htm

 

Free State FX in the USA does custom MU panels. They do them with powder coat and silk screen, like the Synthesizers.com panels.

https://freestatefx.com/pages/custom-panels

They also have been very active lately making MU version of tasty eurorack modules:

https://freestatefx.com/collections/free-state-fx-modules

 

Analog Craftsman in the USA does custom builds and would probably do just panels?:

http://analogcraftsman.com/?page_id=351

 

Of course you can get MU blanks from Synthesizers.com etc and have them milled and engraved by Front Panel Express / Schaeffer. I’ve heard/seen reports from those that have done this and the results seems to be marginal to OK, but not fantastic? AND, there is no reason someone couldn’t do MU panels MOTM style from FPE? Just a thick black engraved plate but in MU widths and MU mounting holes!

https://www.frontpanelexpress.com/

 

Front Panel Express is also offering Digital Printing now so, that might be a way to go for some very fancy looking panels?!

https://www.frontpanelexpress.com/graphics/digital_printing/

Possibly do the digital printing on plain flat panels? Pretty decent images of most MU modules can often be found (try https://www.modulargrid.net/d/modules/browser for starters) and possibly cleaned up in Photoshop and then digitally printed to plain aluminum?

Eric - All -

We took a look at the Randomsource Living VCO PCB - it has some clever features that our panel doesn't reflect (having only glanced at Randomsource at first, we didn't see the VCA/distortion/overdrive feature).  Let us review it and see - I think a modest modification to our design will easily accommodate the full feature-set.  Gotta say - Randomsource sure has done a nice job.  The Eurorack add-on is a clever addition, but, of course, it does we 5U-ers no good.  How was the build?  Easy enough?

I did a version of the rs Living VCO’s for MOTM - pretty much the full feature set of the new panel, including one of the various ways you could use the onboard mixer. I didn’t stick to the grid - I gave up on getting adequate amounts of knobs in a finite amount of space long ago. I just don’t have room for the grid! You can see it here - https://flic.kr/p/Enz4ci

The build probably would’ve been easier if I’d done it on my workbench at home. As it was I worked on this backstage, in the dark, with one flight case as a workbench and another as my chair, on my days off in Las Vegas while Lionel had a residency there over September/October.

It’s certainly the most difficult build I’ve ever attempted. The component density is pretty high compared to what I’m used to, and I guess I’m out of practice for using organic flux solder, but the solder didn’t seem to flow very well across the board or through the holes.

That said, when I got home and fired it up, 2 of the 3 oscillators came up pretty much correctly, as did the driver section. The non-working oscillator was due to multiple cold solder joints.

The layers of documentation - JH’s original drawings and notes, added to by the additional schematics and parts list by RS, which have different component designators than JH’s original docs - made it particularly confusing when putting together the parts order, and infuriatingly difficult to troubleshoot.

In fact, I’ve still got a retrace problem that I’ve yet to be able to suss out: the waveforms all draw correctly, but have strange ringing or notches at the tops and bottoms of the waveforms that change with the position of the Pulse Width pots. It’s the same symptom on all three oscillators. Ideas?
