Machinedrum Randomizer MDPatch for Monome Norns #elektron #machinedrum #monome #norns
video upload by HANJŌ
"Excited to share MDPatch, second of a series of Elektron Randomizers for Monome Norns. It is now available free for the Monome community. This one’s been a real labor of love, built in collaboration with my friend @syntheticjudah, founder of Machine Store—the same force behind the recent resurrection of +Drive support for legacy Elektron machines.
MDPatch is a patch randomizer and performance tool designed specifically for the Elektron Machinedrum, running on Norns. You can explore, randomize, and control synth parameters in real-time via MIDI. It’s a great way to breathe new life into old machines and spark unexpected sounds.
MDPatch came out of countless late-night sessions digging into the legacy Elektrons and wishing for a more playful, exploratory way to shape sounds without diving through menus. With Norns as the brain and MIDI as the bridge, this tool lets you sculpt, mutate, and chance upon new patches in a really immediate way.
We’ve structured it around a 16-page layout—each one corresponding to a track of the Machinedrum and you can find subpages (SYNTH, EFFECTS , ROUTING). You can toggle parameters for randomization, send new patches instantly, and keep that sweet hands-on Elektron flow intact.
Big thanks to this community for being such a constant source of inspiration over the years. If you’ve got suggestions, ideas for expansion or want to share what you make with it—please drop it below"

Pics of the inside below.
"For sale we have the very rare Korg MS-04!
These don’t come up for sale very often.
This is a modulation expression pedal.
It features an LFO (Triangle or Square), a noise generator, and a "bender" type control voltage output, controlled by this sturdy foot switch.
The pedal controls the magnitude of the CV output of the LFO, not the frequency of the LFO.
There is an upward facing LED on the pedal body that shows you the speed of the LFO.
This is in honest to goodness as new condition. The internal date stamp indicated manufacture to be the 6th week of 1980 (which matches the manufacturing period).
There is some light dust on the pedal after being in storage for 20 years, and I haven't cleaned it off. The only blemish is on the front plate indicating model number, where a price tag was placed in the late 1990s when it was purchased by the current owner. I haven't attempted to de-goo it.
One side appears to still have the original protective plastic on it.
All components are original! The tested capacitors have held their values, and the pots were all clean. It has been stored with no batteries inside, and the battery bay, as you can see, is clean as a whistle."

"A relaxing ambient jam using a new patch I created on the Oberheim TEO-5, accompanied by the Sylophone CPM DS-2 drone synth. Effects for TEO-5 were provided by the Walrus Audio Qi Etherealizer pedal, and the Korg NTS-1 (offscreen) provided effects for the DS-2. Recorded on a Zoom H6."

E-mu Drumulator 8 Kits + MIDI upgrade board
video upload by Harry Axten

"ROM switcher boards and third-party sound ROMs are nothing new as far as the E-mu Drumulator is concerned – in fact both were available while the machine was current. JL Cooper Electronics and others made 3-kit boards, and Digidesign (who later became Avid) got their start producing alternative sound ROMs for the Drumulator under their original name of Digidrums. That said, while the various alternative ROM sets are easy to come by these days, ROM switcher boards are not, and without one it’s a total pain to keep swapping chips in and out as you have to take out 8 screws on the underneath of the thing, lift off the lid, swap 5 chips over and put it all back together again.
8 Kits
I wanted a modification very much in the same style as my TR-707 ROM expansion board, with a number of kits that you can instantly switch between. As with that project, this is done without the need for any additional switches and instead uses a microcontroller to snoop on the front panel switch matrix. Kits are selected by holding down one of the bottom row of buttons marked 1-8 and pressing the ENTER button. The selection is remembered when the Drumulator is powered off too.
The Drumulator’s sounds are stored across 4x 16kB ROM chips, although they form one continuous region of memory. Thanks to this, and due to the way that they’re selected, it’s really easy to replace all four with a single large capacity chip. The 512kB flash ROM that I used can hold 8 kits worth of sounds, which works out nicely as that’s the stock sounds plus 7 of the Digidrums kits, including the famous Rock Drums kit:
Stock kit
Digidrums Alternate Drum Set 1
Digidrums Electronic Drums 1
Digidrums Electronic Drums 2
Digidrums Rock Drums
Digidrums Jazz Drums
Digidrums Latin Percussion
Digidrums African + Misc Percussion
Because each kit also has a corresponding modified program ROM (as the length of sounds, locations in memory and channel assignments are all hard-coded into the Drumulator’s firmware); the D8KM board also has an EPROM which contains the relevant OS for all 8 kits, and is connected to the Drumulator’s OS ROM socket with a ribbon cable. Fortunately the Drumulator doesn’t care if the OS ROM changes while the machine is running as long as they’re all the same version, which they are – ‘P3.00’, the final version.
MIDI
I chose also to include MIDI functionality as part of the upgrade, as most Drumulators don’t have it. E-mu did offer a retrofit, which has been cloned over the years, but it’s very basic and only does MIDI notes. The D8KM board on the other hand also offers the ability to sync the sequencer to incoming MIDI clock. Just set the Drumulator to external clock and if MIDI clock is available, it will automatically override the external clock signal and will also start and stop playback. If MIDI clock is not available the Drumulator will use the external clock signal as normal, including for the tape loading functionality."

Sounds From the Future in 1930
video upload by Production Zone
"At 1930 it Sounds from the Future | The Father of Synths nobody talks about 🎛️⚡
Meet the Trautonium, one of the first electronic instruments ever made — way before synthesizers became mainstream. 🎛️
⚡
Invented in 1930, this futuristic machine uses a resistor wire and metal plate to create wild sounds, with techniques like vibrato, glissando, and even quarter tones. Absolute music history right here. 🕰️🎶
The Trautonium, an early synthesizer that alongside the theremin and the ondes martenot is considered the pioneer of electronic instruments."
