MusicThing Modular Spring Reverb by Tom Whitwell

MusicThing Spring Reverb
Module
Tom Whitwell, known to many as the man behind the MusicThing blog, his Turing Machine- project (plus expanders) and various other syth-related projects, has cooked up something new again.

His latest Voltage Controlled Spring Reverb module is a eurorack spring reverb module that has a circuit that is inspired by a few other synth designers.
The end result is a spring reverb module with a few interesting extras... 
For example, this design features a voltage controlled vactrol crossfader that you can also use independently.

In the following videos Tom shows us what the module can do.

Video 1: Music Thing Modular Spring Reverb

" Spring reverb module for Eurorack modular synths. Audio is slightly out of sync with video, sorry. Full details below...
Controls: Top knob is reverb level.
Right hand smaller knob is Tilt, a simple hifi-style tone control that changes the colour of the reverb.
Left hand smaller knob is Control, an attenuverter control for the incoming CV. 12 o'clock = no CV, clockwise = increasing CV, anticlockwise = inverted CV.
Patch: DPO sine waves sequenced by Turing Machine and Wogglebug. Gated through QMMG, envelopes from Maths. The CV input makes 80s-style gated reverb and pseudo-reverse reverb possible.
For this demo, using a 9EB2C1B full sized reverb tank. "

Video 2: Music Thing Modular Spring Reverb Crossfade Mode

" The MTM Spring Reverb contains a vactrol crossfader that you can also use independently. Here, it is crossfading between the DPO Final and Square outputs.
The module can be built with either a Silonex or a VTL5C3 vactrol. The VTL5C3 sounds smoother for this use, with a slower response that can be 'pinged'.
Video and audio are slightly out of sync, sorry. "

This is again an open hardware project – all the project files (Eagle CAD projects, Gerbers PCB files, a Mouser BOM and Illustrator/PDF front panel designs) will be available soon on his web-page, covered by a Creative Commons Attribution Share-a-like license, which allows for commercial use.

Update 26/10: Documentation and schematics now available via http://musicthing.co.uk/modular/?page_id=579

DIY Modular Case Ideas

There are many ways to house your (eurorack) modular synth, i wrote about the pre-manufactured options from Doepfer earlier, find that post HERE, but of course you can also try to build you own case.
There are many ways to make your own A-100/Eurorack case if you start out with just the basic rails and busboard, and you can make it as cheap or expensive as you can.

Check out a few ideas;
Wooden cabinets and side-panels are still very popular amongst (modular) synth enthusiasts.
These simple case standards for the pre-manufactured LC9 cases are very simple, and can be sooo useful

Matthew Goike (@Goiks) also has some nice wooden cabinets on display and for sale on his website: http://www.goike.com/node/5

...or do what Stretta did (or rather what his brother did), make a high-end wood/brushed aluminium cabinet with integrated LED-lights and some …

Doepfer A-150-8 Octal Manual/Voltage Controlled Programmable Switches Announced

Doepfer has just released some info on their new modules for NAMM 2017 (19-21 jan.) Besides some vintage editions of existing modules, the A-135ABC VC Performance mixer modules, the A-110-6Trapezoid Thru Zero Quadrature VCO and a new A-100LC1 case (economically priced small housing with 48 HP width) there was also one other interesting new module announcement:
Module A-150-8 contains eight manually/voltage controlled switches.  Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2).  The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. 
Two LEDs show which in / output is active (ie. which is connected to the common out / input).  In addition the LEDs are used for the programming of the module: For each unit the operating mode can be selected:  Toggle or Level controlled. In Toggl…

Happy New Year From PatchPierre

Hi there, it's me again... Happy New Year!

You might have noticed that I havent posted a lot in the last 2 years...
It's been a rough time for me since the sudden loss of two parents within a relatively short time-span and I really needed some time to get myself together... to set things straight, finding myself and selecting priorities... even my regular work suffered from this breakdown.

It took a while to understand it all, and to get a better grip on it, and it's sometimes still not very clear.
I think I have found a way to cope with most of it now... although the slight autism that I have (ADD-like) doesn't make it easy for, especially in crowds with lots of people I don't know...
On my journey I also (re-)discovered the beautiful woman that has always lived inside of me and that i need to accept and cherish... more on that maybe later... I'm not considering changing the name of the blog to PatchPetra.Net 😇 (...yet), but you might spot me somewhere at mod…
