Matrix Patching & Patch Storage

Matrix Patching & Patch Storage

2000-02-29 by alt-mode

Dave,

Thanks for the comments.  I have worked with a VCS3 and the matrix patching can be
quite confusing.  It's not very easy to visualize the patch on the matrix. 
Actually, the first synth I ever played had matrix "pushbuttons"; anybody ever
played an Ionic Performer?  Again, it was confusing to "see" the interconnections
between the modules with the matrix especially for someone playing a synth for the
first time without a manual!

The 2500 patching is a bit different since you use the switches to select and
interconnection between modules.  What I'm wondering about is if this is any
easier/better to visualize the patch with.  My guess is that it is better than an
EMS patch matrix but harder than patch cords, except when they get really tangled.

I suppose I too am addicted to patch cords; I'm just exploring other options that
can help with that modular "lateral thinking"...

Along the same lines, how do folks "store" patches from their MOTM systems?  I
haven't bothered to write things down yet, preferring to have my patches as a form
of temporary "art" but I wonder if any folks just get out a notebook and write down
a block diagram or do something else.  Thoughts?

Does anyone remember the old "programming" board from the early IBM 
computers?  These were framed panels that you would patch, similar to a large 
patchbay, and then insert the whole panel into the computer.  Interesting 
concept to do something like this for a modular synth.  I used to have one of 
these laying around as a reminder of the past... now I'm thinking it might be 
interesting to use in the future!

I was thinking that there must've been a time in the development of modular 
gear, that people were using binding posts and just stripped and tinned wire 
-- no jacks at all. I've been meaning to ask this on the diy list when 
pro/con connector threads start showing up.

I rarely (never) log my patches, if I come up with something new to me, I'll 
generally leave it patched up for weeks, and change the other stuff around 
it, until it becomes part of my "patch repertoire." In EM classes, I did log 
patches, but found the real important if subtle info is lost (like 
relationships between two oscillators in some FM patch for example). I have 
said that MOTM stability and large knob size might make logging patches 
easier.

You mean like those phone bank patch blocks?  I remember working as an
assistant sysadm a few years back and working on some in the basements of
several musty concrete semi-government buildings, and thinking that the
punch-tool was my best friend.  That, and a continuity tester.  Wish I had
learned more from that job, though... But I digress...  those things would
be hellish to work on; I can't imagine that it would take long to progress
to jacks.  What I wonder is if there was ever a modular with rip-cord jacks,
where when you unplug the jack the cord retracts back into the modular.
Unpractical as hell, really...

this got worked out before vc synthesizers, probably with early computers
or even telphone equipment or before.

I've seen the first buchla prototype and it had jacks in it.

I have tried to document a few patches, but it is a time consuming process.
 I am thinking hi-res digital camera might be a decent idea.  I've been
wanting one anyhow.

Reminds of the days before "total recall" mixing consoles where the studio 
would have a camera mounted on the ceiling above the console.  You would take 
a photo of the console, have it blown up, and later use it to "recall" 
settings.  A "settings snapshot" literally!

hello all,
you can't believe how close i was to doing this. a government surplus depot
down in nottingham had an old 30s/40s/50s telephone operators console, gpo
retracting cables everything, about the size of an upright piano, i knew as
soon as i saw it that this was the only stylish way of patching my growing
modular - fortunately, the beast wasn't for sale, i mean it was huge, and as
you correctly point out unpractical as hell, but damn stylish
funnily enough i'm off down there on saturday - on a joystick raid (aviation
or otherwise)
meanwhile, back in the real world - i made up a rough patch sheet for my
motm, so if i come across anything unusual, it's just a case of drawing
lines and marking knob positions

An amazing amount of what we think of as audio studio gear (equalizers, test
oscillators, filters, even vocoders) started out life as adapted equipment
from the telephone industry. Patchcords in modulars are older than you might
think-where do you think the 1/4" plug came from in the first place?
Telephone switching equipment.

Re: Matrix Patching & Patch Storage

2000-03-01 by alt-mode

I think there was some relationship between Ionic and EMS.  I read somewhere that
Ionic distributed or purchased most of the EMS synths in the US for awhile.  The
Performer certainly had a resemblance to the Synthi's.  I think it had 4 oscillators
with the same verner dials and variable waveshapes as EMS.  I believe it even had
"trapezoid" controls on the EGs.  I *do* recall the Performer had tuning stability
that was about as good as an EMS synth!  [Shudder.]

Both the Music Easel and the VCS3 MkII had boards for "storing" patches.  On the
EMS, the "Presto Patch" cards stored a configuration of the matrix pins.  You still
had to set up the knobs yourself.  On the Music Easel, you could set up patch
interconnections and slider values (with resistors!) on the program boards.  Music
Easels came with a set of the boards and a few boxes of resistors for common slider
values.  Cool ideas for the first "programmable" synths but you'd better really like
a patch in order to match resistor values and solder them onto a board.  The Easel
had a three position switch to select the front panel, the program card, or both.

This technique was even used in the late 70s (although invisible to the
user) by Yamaha on their CS-15D preset synthesizer - there's a board inside
covered with banks of resistors that "replace" the front panel knob
settings (actually, it's bitimbral, and only one of the timbres has knobs -
the other one only has the presets; one of my if-I-ever-get-around-to-it
DIY projects is to pull out one of the resistor banks and replace it with
an interface to an external knob box ... not likely to happen soon since
the synth is on semi-permanent loan to a friend 150 miles away).

At the current time I don't have enough modules to justify this, but I plan
on making an outline drawing of all the modules and then arranging them
into a patch sheet (similar to the patch sheets they gave you in the back
of the memorymoog owners manual.) If anyone is interested email me with the
layout of your system ( ie: row 1: 3 800's, 700, 800, 120, row 2: 410, 420,
440, 900, etc.)  And i will send you a gif you can print to use as a patch

Re: Matrix Patching & Patch Storage

2000-03-02 by J. Larry Hendry

Nathan, I think this is a nice solution.  I use this on several of my
smaller synths.  My Micro even came with plastic sheets you could layover
the top.  

I have a  .BMP file of my system like that with a drawing of each module. 
Actually, Chris did the original artwork.  I took his system, did a few
modifications, a little cutting and pasting and I have it.  It is a bit too
small for patching, BUT, that is what they make those zoom / size buttons.

Well, this is a good indicator since Buchla was one guy I was thinking of in 
particular, and I'd guess this prototype was built around 64 to 66. I'd like 
to hear more about Buchla's stuff and development since I've never used any 
of it but always thought it was intriguing. If you (or anybody) can talk 
about this stuff wrt MOTM future developments I'd love to hear it.

Yeah, this is more what I was thinking about, the late 40s to the early 60s. 
While we're all familiar with the bigger studios in Europe and the US, there 
must've been "guys" in their garages (like Bob Moog in the early days, or the 
Barons, or Les Paul but with les money -- get it?) fooling around with this 
stuff before we had 1v/oct standards, or such a beast as a "synthesizer" (a 
word I dislike).

You make a very good point. I was thinking that jacks and plugs add great 
expense when you are buying a lot. But phone switchboard jacks (aren't these 
the same as TRS jacks in studio patch bays?) were probably quite readily 
available as scrap even, and a large studio in the 50s, probably only had 
about as many "modules" as an ARP 2600.

Patch panel proposal (not really for MOTM -- patch cords are much more 
"flexible" -- get it?): 
A field of 1/4" stereo jacks such that the tip connects to the output from a 
module, and the ring connects to the input of the module -- the bad news is, 
each jack would have to have a 100K associated with its ring (either on the 
ring of the jack, or on the particular board).
Then you get a stereo phone plug and just solder a jumper between the ring 
and the tip.
The main advantage of this type of matrix, is that you could just plug a 
standard 1/4" patch cord in any jack and use it as an output, with no effect 
on the associated input -- and no need for multiples.

Just a thought!

I'm glad Crow heard the Moog interview on Monday -- it was nice to hear Terry 
ask him about using such mundane controllers as a standard keyboard.

Hey Fred, did ya get that 120 going?

I wonder how that compares to my NON-preset CS-15.  The CS-15 (sans) D is
monophonic rather than duo-phonic.  Cool synth 2 VCO, 2 mixers, 2 VCF, 2
VCA, 2 EG, 1 LFO, external audio in, glide circuit.  Since the CS-15D was
duo-phonic, I wonder if it had two of everything?  Someone mentioned how
cool it would be to substitute controls for one of the preset boards.  I
agree.  No patch cords on this one, but it has switches, to route and
select things like which EG to which VCF, VCA, etc.  Anyone every seen a
CS-15D?  Unfortunately, the CS-15 is plagued by the damn V/Hz VCO control
standard.  I have a link to a photo of one if anyone is interested in
seeing a CS-15 (actually my CS-15).

Nope, you're not missing anything.  This is why the EMS Presto Patch interface
became the "Computer Interface" port in later VCS3's.  I think folks found them a
bit difficult for live performance use.

I could be wrong on some of this, since I don't have easy access to my
CS-15D and it's been a while since I've seen a plain CS-15 ...

Both CS-15 & CS-15D are mono-PHONIC, but they're both bi-TIMBRAL ...

>Cool synth 2 VCO, 2 mixers, 2 VCF, 2 VCA, 2 EG,

... because the two VCO->VCF->VCA/EG paths are parallel and independent of
each other (as opposed to, for instance, the 2xVCO 2xVCF MS-20 where both
VCO outputs are mixed together and go through the two filters, HFP & LPF,
in series).  This would actually make a good MOTM patching exercise (in an
attempt to keep this vaguely on-topic) for someone who owns two each of
-300, -420, -800 & -110 (for the VCA): compare and contrast the
capabilities and sonic ranges of the two-oscillator monotimbral patch vs.
the one-oscillator bitimbral patch ...

... or do the two mixers on the CS-15 (not present on the CS-15D IIRC)
allow you to pan each VCO between each of the two VCF->VCA paths, as
opposed to the forced segregation of the two VCO's on the CS-15D?

>1 LFO, external audio in, glide circuit.  Since the CS-15D was
>duo-phonic, I wonder if it had two of everything?  

I'm 99% certain that the guts of both CS-15's are the same, and that the
only difference is that one of the timbres (i.e. VCO->VCF->VCA/EG path) has
no control knobs.  Instead, that part of the front panel has two rows of
preset buttons, one for the timbre with control knobs (which are disabled
for every preset except the "manual" one), and one for the timbre without
any knobs.

Which would, I believe, essentially convert it into a normal CS-15 with
presets.

Those Yamaha CS- synths DO have very nice modulation routing capabilities
(love 'em on my CS-40M!  Which, BTW, I made a patch sheet for in Visio a
couple years ago).

Works great with Korg MS- synths!

I'd like to.  Sorry I don't have any available pics of the CS-15D.

Thanks Doug.  I got confused by someone's comment about the CS-15 being
possibly duo-phonic.  I can see how the knob 1/2 and preset 1/2 would lead
one to "think" of it that way.

I see.  I think the mixers are a huge feature on the CS-15.  You can be
bi-timbral as you say in actually TWO different configurations.
One: would be one VCO, one VCF, one VCA, one EG per timber.  Or...
Two: both VCOs on one timbre and noise or external VCOs on the other timbre

Yep.   For a simple mono-synth, it is a sweet puppy.

Yes, I have a MS-20, but I am about ready to part with it.  LAst two on
E-bay have sold for $1200-1400 range.  I don't like it THAT much.

eric,
okay, good - i worry sometimes about overlooking the obvious ( even worse 
without personal experience with the machine ). the computer interface would 
have been cool with a nice software enviroment ! did they have software or 
was it delivered as "bare iron" ? or, perhaps, a scaled down version of their 
musys system ?

[Catching up on a few threads.  It seems that Onelist and Yahoo weren't exchanging
mail that well on Thursday and Friday and I missed some MOTM mail, horrors!]

Dave,

I don't think the EMS prestopatch-interface-relabeled-as-computer-interface ever
went very far.  From what I have read, only a few experimenters every got it to
work.  That sounds pretty "bare-iron" to me.

eric,
thats too bad - a relatively simple ( and simplified ) port of their "musys" 
music input language / control system would have been really cool and opened 
up a lot of possibilities for their users.  :^(
