Oberheim SEM SUB-oscillator Mod

"I saw this SEM SUB-oscillator floating around the internets and had to give it a go. 5 stars would go again. Available here from ‪@Lackan110f‬ https://reverb.com/shop/peters-gear-g..."

Note the Marion Systems logo on the board. As readers of the site likely know, Marion Systems was Tom Oberheim's follow-up company after Oberheim.

"SUB-oscillator module for the New Oberheim SEM Pro (2009). Installation is very simple, you just have to solder one wire to the +15V point and then attach three connectors.

The +15V point can be located in various places depending on if it is a Marion or Oberheim, and also what model it is. So a multimeter is recommended to verify +15V.

This will give you a -1 octave SUB-oscillator using the EXT-IN knob #1, or a -2 octave SUB-oscillator using the EXT-IN knob #2.

You can also mount it so that you keep EXT-IN on #1 and have SUB -1 OCT on #2 (SUB -2 OCT is then omitted). Se illustration.

Does NOT work in an older vintage SEM (1974-1979) due to different connectors. (the video shows a vintage SEM, but this product is for the New TOM SEM Pro 2009)"

1. Bristronica 24: MyVolts The Silent Alchemist Nears Shipping

We caught up with Caroline who gave us the latest update to the *Silent Alchemist*, a versatile power hub designed for musicians. Featuring five isolated USB-C outputs and a high-wattage sixth output capable of delivering 100 watts, the device can power a Mac with the remaining outputs providing 20 watts each. Its independent circuits ensure noise-free operation, catering to a variety of devices including the Dreadbox module and Sysmo slope generator.

The Silent Alchemist uses innovative step-up power tips to convert USB-C input to the correct voltage for various devices. There's also new feature: an uninterruptible power supply allowing seamless transition between wall and power bank sources. Also introduced were updated cables, such as silver candy cords and floating ring TRS to TS cables, expanding connection flexibility. The Silent Alchemist is expected to be available in December with a competitive pricing strategy.

2. Bristronica 24: Circuit Happy ML2M Clock Sync module updates

At Bristronica 2024, we caught up with the creator of the *ML2M*, who introduced us to the latest version. The ML2M is a compact Eurorack module with Wi-Fi capabilities, allowing seamless synchronization with Ableton Live, Bitwig Studio, and iOS music apps using Ableton Link without the need for cables. It either connects to an existing network or creates its own, ensuring robust sync even in environments with unreliable Wi-Fi. The module, which retains its 2HP size, now features MIDI integration through TRS jacks. Users can access a web interface to configure each output for different clock divisions and reset triggers, making setup straightforward and flexible.

Alongside the ML2M, there's also the Missing Link Junior. This desktop version offers the same functionality but in a box format, complete with MIDI and CV clock outputs. Both products are now accessible, with a starting price of $250.

3. Bristronica 24: Archaea Exchange Patching Module

At Machina Bristronica 2024, we caught up with Arran from ‪@archaea_modular_synthesis‬ who presented the *Exchange Module*. This programmable patcher, a year in the making, evolved from its early prototype stage to a fully functional module. Arran explained how the Exchange can route synth voices via a beam controller and three exchange modules installed within the skiff, allowing for versatile patching. Operating like a matrix patchbay, it enables users to select inputs and outputs with the push of a button, create presets, and chain multiple modules for synchronized patching.

Communication between the modules occurs over the Eurorack power bus as well as over MIDI via the USB-C connection. The Exchange maintains analog integrity, ensuring there’s no conversion latency. The forthcoming release expected in late November 2024, includes a USB-driven editor for enhanced control capabilities.

Prophet ’08 Desktop PE Conversion Kit: Time-Lapse

"Decided it was time for the ’08 to get a little upgrade. Gave me a chance to test the Time-Lapse functionality of the OMD as well. Went pretty smooth outside stupidly of destroying PCB trace! A little wire mod fixed the situation.

"Oberheim SEM Pro / SEM (Original 1976) comparison. I feel It's safe to say, if it's it an Oberheim SEM it's synth magic."

MF-104M / MF-104Z / BD101 Experiment

"I've recently added a Moog MF-104M & MF-104Z to the arsenal. I didn't originally plan on keeping both, but they ended up being very different beasts. The 104M has fuller bandwidth, smoother sound, & modulation. Not to say that you can't drive the hell out of it, It's covers a lot of sonic territory. The 104Z has a grit & chaotic feedback loop that I love. I pulled out the D-Scope & analysed the two. You can see the frequency response & THD+N of the dry signal & the BBD Short/Long delay modes in the images below."

I shot a comparison in my dimly lit room. The 104M audio is in the Left channel & the 104Z is the Right. The last 2 minutes or so show off the self oscillation."
