TTSH (ARP 2600 clone) build notes - Voltage Processors (DIY)

Part 15 of the TTSH build.
I love this section of the ARP 2600. They are not as sexy as the filter or VCOs but still very useful.

This is the voltage processor section on a ARP 2600




Below are some demos using my vintage 2600.


And the lag processor:



It's a awesome module.
Anyway, this is the next part (no.14) of my TTSH (Two thousand six hundred) build which is an ARP 2600 clone synthesizer.
You can see my full build thread HERE
There are two awesome TTSH threads in Muffs.
2600 clone - Two Thousand Six Hundred (TTSH)
and
Two Thousand Six Hundred (TTSH) Project General Build Thread
The DSL-Man site has a very good TTSH thread
And of course the official build thread is here

Elektron Rytm & Buchla (Test 1) - Cobramatic & JonDent

Just trialing out the new Elektron Rytm drum machine with some Buchla.

The Rytm is sending midi clock to the Buchla/Euro modulars.
Perfect Swedish precision.


Here are some links to unlisted videos from the night:

Buchla Easel & 208r - Patch C

Mixing up some sounds from a BEMI easel and a Buchla 208r





Jam # 3 - Cobramatic

Experimenting with the Buchla Music Easel and a 208r (Buchla clone)



Some links to unlisted patches:
(These are only accessible via this blog).
Buchla Music Easel & 208r - Patch 2
Buchla (BEMI) Easel & 208r - Patch 3




Metasonix R-56 Tube Reverb.

A few test videos of the Metasonix Vacuum Tube Reverb. - R56.


The videos are a bit low fi- recorded on a mobile phone.
So my apologies for the audio quality.
Here we (Cobramatic & I) are testing the R56 with a Buchla music Easel)

The feedback dial is EVIL.if you love distortion like I do.
In this video we are running a Endorphin.es Furthrrrr Generator
through the R-56. The Furthrrrr is a Buchla 259 inspired eurorack module.

Here is the blurb from Metasonix

Buchla Music Easel & Vermona Drum

Playing with the BEMI Easel.

The Easel is clocking the Eurorack TriggerMan (Delphtronics) which is in turn
triggering the Vermona DRM 1 (Mark III).


Some pics:





Who's the girl (playing that 1960ish Moog Modular)?

Does anyone know who this girl is?

I'd love to know her name? Is she a musician?

I understand that The R.A. Moog modular that she is playing is this one (bar some different modules in the upper right of the top case and the absence of the second keyboard):


The system includes:- three 901 VCOs, 901A VCO driver, four 901B VCOs, 903 White Sound Source, two 904-A LPFs, 904B HPF, 904C filter coupler, three 902 VCAs, three 911 envelopes, 911A dual trigger delay, 907 10-band fixed filter bank with a unique original switching system, and a five-octave keyboard
with portamento.

The basis of the system dates from August 3 1967. I understand that the picture with the girl was taken in the summer of 1969. There is a record of a second service being carried out at R.A. Moog when the extra cabinet & modules were added).

This modular is the 10th proper system sold by Moog since they started keeping records (based on serial numbers) at the beginning of 1967. Professor Emerson Meyers of the Catholic University electronic music studio used it  to create the late 60s LP "Provocative Electronics".

Buchla Jam 3 - Acid sounds - Cobramatic & Jondent

Some trial patches and recordings from last Sunday night (15th June 2014).
I thought I'd upload this info to help in recalling these patches for future gigs.
DJs Cobramatic & JonDent

The recording is only from a mobile phone so sorry for the lo-fi audio quality. The square wave from the 262v is very special.

And some pics from the night.



Below are some links to extra (unlisted) videos we recorded on the night.

Buchla Glitch drums

Some new collaborative patches & jamming with Paul A (a.k.a. Cobramatic).
We are trialing out some gear (mainly a Veroma DRM drum and assorted Eurorack modules)
with our Buchlas.

I really like the Vermona DRM 1 & Tiptop Trigger-Riot.


Below is an earlier recording taken on my smart phone.
The recording quality isn't as good, but it was recorded with the lights on so you will have a better idea of the patch:

And some pics of the patch:


 Nice. Dual MM u-Steps

The Vermona DRM 1. It's a great analog drum machine.

What U is that synth ??? - Modular synthesizer sizes.

Confused with the different sizes and dimensions that modular synth manufacturers use? 
Well here is a brief break down of how they measure up with one another.

Most synth manufacturers use varying widths, but standardize when it comes to height.
The dimensions they share stem from  rack mounted equipment (audio & computer).
Modular synths between 3U and 6U are the most common.
Width and height are the most important factors.

Width is usually measured in units of TE (TeilungsEinheiten, german.) or HP (Horizontal Pitch)
One TE/HP = 5.08mm = 0.2inches or 1/5"

Height is usually measured in terms of  HE (HöhenEinheit, german.). or units (U, english)
One U =  44.45mm = 1.75 inches.


                  *******************************************************

 


1U (1.75 inches or 44.45mm) Not a very common size when it comes to modular synths.It is used extensively in audio gear. Some synths that use this format are Thomas Henry & erthenvar
Dopefer also produced a few 1U synths like the MS-404. Not a modular though.

Erthenvar sell 1U PulpLogic modules such as this Sample & Hold.
Very handy if you have limited space.

2U (3.5 inches or 88.9mm) Again, this is not a very common size when it comes to modular synthesizers. This height is more common with audio gear. Some rack mounted synths that are are sold in this size include the Paia Fatman and the Waldorf Pulse. And one of the most popular digital synths to ever come from Roland the JV-1080 took the 2U format.
Wiard does produce a 2Unit 311C Dual JAG Controller

 3U (5.25 inches or 133.4 mm) This is probably the most common size when it comes to modular synths.
It includes the the huge Eurorack/Doepfer range and all Frac-Rac, Blacet, Wiard, Metalbox, BugBrand, PlanB, Livewire, Bananalogue, Analogue Solutions, Analogue Systems, NonLinearCircuits (NLC), Synton, Paia, Metasonix, etc, etc etc
An assortment of 3U Eurorack modules from different manufacturers. (Blue Lantern, WMD, ADDAC, Snazzy effects).

Doepfer's 3U mini synth voice the A-111-5 (it's the eurorack version of the Dark Energy) next to Din Sync's modularized Roland TB 303 filter.

4U (7 inches or 177.8mm) Serge - STS , polyfusion
(out of production), NonLinearCircuits (NLC) , Driscoll & Buchla

Three Buchla 200e modules:281e, 292e.261e. Each is 7" high and 4.25" wide

A panel of Driscol modules. Width varies but height stays the same (7").


An early 70's era Paperface Serge 4U modular panel (7" x 17").

The 4U NonLinearCircuit Cellular Automata sequencer panel.

 5U (8.75 inches or 222.25mm) MOTM - Synthesis Tech, Moog, Synthesizers Dotcom, Encore, Modcan B series, Metasonix. 


The Moog modular synthesizers use the 900-series of modules.

(almost) 5U Modules : Cyndustries  Format A & Modcan  A
Modcan A modules are 9" high (5u is 8.75 inches) and single width modules are 2.25" wide
The most compact packaging is the Cyndustries sixpacks (13.5" x 9" x 7"). These are entirely different from the dimensions of 19" racks.




6U (10.5 inches or 266.7mm) Wiard 300 series. They are designed to fit in a 19" rack mounting frame (6 across)

9U (15.75 inches or 400.05mm) - A Real Monster of a Synth  : Technosaurus

 

------------------

ARP 2500
 
ARP 2500 modules don't follow a "U" convention.
At exactly 8 inches high, they lie between 4U & 5U
