"Dave Smith Instruments Poly Evolver Keyboard in excellent condition. Encoder version with updated boards.

Main Board: 2.2 Voice board: 2.2 DSP Board: 3.5

I'm the second owner, and both studios were non-smoking. No gigging with this one.

This is a special synth from a very special manufacturer. Dave Smith, from designing the famous Prophet 5 to his defining the MIDI spec, really dedicated himself to producing unique and capable instruments and technologies. This Poly Evolver is one of those. Full Specs below but the fact that this is a hybrid synth, combining analog and digital synthesis, with incredible modulation and built-in sequences, show the mind of genius Dave Smith.

Also the purple heart wood is an beautiful accent for this particular synth."

RF dawless jam 147bpm

video upload by Radical Frequencies Modular

"Patch: Bass is the Dpvco mixing the alpha square with beta saw slightly detuned into the RF transistor mixer and into SH Vcf. The decay of the envelope filter is voltage controlled by Lucky Voltages giving a bit more groove.
The lead is a simple saw into the Diode Dream Vcf which can make internal fm from Vcf input to the filter cv frequency. This resonance sounds so bubbly and glassy with beautiful mid high frequencies!
All drums are from different sources mostly analog mixing into a vintage 70s mixer. The jam is directly recorded into daw. Sequencing is done with Beatsteppro."

Tre Modular - Liminal Space Demo

video upload by Tre Modular

"Liminal space is Eurorack delay module that has two parallel cores that share the same repeat line. Both of these cores are based on PT2399 IC. Even though PT2399 is not an analog IC, we have made sure that Liminal space sounds and feels like classic analog delays of the past. Each of the cores has different supporting circuitry. This changes what sounds get passed through the delay and how fast they fall off. This results in unique interaction between both of the cores. We have also added Modulation input that lets you modulate both channel speeds in an eerie way that produces That nostalgic sound.

Huge thanks to Lelde for lending her hands and talent.

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"

Korg MS-04 Modulation Pedal

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."
