BENJOLIN VALENTINE
I always wonder what will come in for Valentine's day. Here you go. :)
"Benjolins rock, this one modulated by a MoogCP251 voltage controller passes thru an Instruo Athro wave folder, then on to a MF107 Moog FreqBox and then off into an H9 Blackhole Cigaroo preset. Turn up the bass!!!"

Expanding the Sequential TOM to hold 16 "cartridges"
I bought my TOM a few years ago, and had always intended to make some sort of switch-able cartridge for it. I decided recently that it would be nicer to have everything inside the TOM, if possible, and control it using the TOM user interface. There are two advantages to doing it this way:
1) Cartridges can be selected without unplugging and replacing EPROMs, which can get damaged by ESD or bent pins.
2) Both the internal sounds and the cartridge can be swapped out, so all 15 sounds can be changed, not just the top 7. There are two "slots" - internal and cartridge. Any of the 16 "cartridges" can be placed in either slot. If a cartridge has seven sounds in it, and is placed in the internal slot, button 8 will not make a sound. All of the cartridges I have made have 8 sounds. If they are placed in the internal slot, all 8 are available. If they are placed in the cartridge slot, only the first 7 sounds are available.
The board plugs into one of the internal sound ROM IC sockets, after both chips have been removed. It also needs A15b and A16b which are not available in either socket, so two short wires are used. I use A15b and A16b instead of A15 and A16 to avoid connecting to the Wonder chip signals. Luckily there are eyelets on the TOM board right where I needed them to be for these two signals.
Here is a photo showing the newer version of the pcb, which has a third wire. The original two wires are connected exactly as before, while the third wire attaches to the lower end of the 10K resistor near the battery. I have added a small circuit which should allow inserting a cartridge (for testing) into the TOM while the TOM16 is installed. In this case, the only sounds available would be the ones on the cartridge, as the TOM16 EPROM is disabled.
How does it work? I added code to the TOM V1.6 OS firmware (the final SCI version) to allow selecting cartridges using the std user interface. Once the selection is made, these values are sent using the Wonder chip in a special way to a PIC micro-controller on my board. That chip presents the two cartridge select 4-bit codes to a dual 4:1 mux that feeds the correct one to an 8 Mbit EPROM. I do not plan to release the PIC code, or provide the source for my version of the TOM OS at this time. The only changes that I made to the TOM OS firmware were for TOM16 support. No other changes were made.
I am currently offering fully assembled pcb's for $105 including Priority Mail shipping to USA addresses. If you are outside of the USA, please contact me for the additional shipping cost. In order to install the board in your TOM, you will need to upgrade the (socketed) firmware EPROM with one that I supply. You will also need to remove the two (socketed) sound ROM chips I610 and I611. And finally you will need to carefully solder three wires, (which I will supply) into small holes in the TOM pc board and in my board."

Haven't seen one of these in ages.
"Alesis Photon X25 MIDI Controller + 2ins/2outs audio interface
This MIDI controller is not young, but it's still in very good condition and works perfectly. Maybe a little cleanup of some knobs will be necessary and the pitch wheel be calibrated, but otherwise it's in very good condition!
The built-in USB audio interface is Class-Compliant, which means it is compatible with Android, iOS, Win, Mac, Linux and all variations.
Of course, the main appeal of the Photon X25 is its unique AXYZ infrared dome, which allows you to control anything in 3D. While it's not ultra precise, it will give you hours of fun and experimentation!
The best of both worlds! The Alesis Photon X25 USB/MIDI Keyboard Controller with Audio combines superior USB/MIDI control and high-quality recording in one cool package! Unique features like the Axyz Controller dome and 10 - 360 knobs give you powerful MIDI control over your software apps. Balanced 24-bit, 44.1/48kHz audio I/O allows recording and playback from your computer. The Photon X25 has a 25-key, velocity-sensitive keyboard with full-size Pitch and Modulation wheels. LCD screen with dedicated encoder for fast and easy set up. User-customizable templates can be placed on the front panel. The Alesis Photon X25 operates on USB power, optional external adapter, or 4 C batteries (not included). Windows XP/Mac OS X-ready. Features
25-note, full-size, semi-weighted keyboard

Evolution Vol 3 - Patches 76 to 100 - Sequential OB6
video by GEOSynths
"Out Now - https://www.geosynths.com/dsi-ob6
It's been almost 3 years since I brought out Evolution Vol 2 for the Sequential OB6 Synthesizer and wasn't sure I'd do another, however Sequential have updated the OB6 with the "Vintage Knob" feature, from the Prophet 5 Rev 4 Synth. After playing around with it, I decided to do another Bank and while it is subtle with some sounds, with others, it can really make a difference.
In this set I've also focused a little more on making Patches using Osc 2 as a Modulation Source and delving deeper. While there is the odd "Vintage" patch, it's more about getting new Synthesizer sounds."

Evolution of the ARP 2600 - Synthchaser #135
video by Synth Chaser
"In this video I give you a brief look at the evolution of the ARP 2600 synthesizer, from the Grey Meanie, one of the very first units produced in 1971, to the final black & orange models made through 1981."
New Axel Hartmann Design Website and the Luca Anzilottis Schmidt
This one was sent my way via Soviet Space Child.
Renowned synth designer Axel Hartmann has a new website at https://axelhartmanndesign.com. If you own a synth or two created in the last three decades, chances are the look and feel were designed by Axel Hartmann. He has designed synths from Sequential, DSI, Moog, Roland, Arturia, UDO, Waldorf, and of course his own synth, the Neuron. He even designed the BlipBox! You can find stories behind many of his designs on his site and a list at the bottom of the about page here.
Pictured left is the 20 Synthesizer.
Below is one I haven't seen before. The Luca Anzilottis Schmidt.
