See the seller's other listing for more.

"This is the rarest first version of the amazing sounding Crumar Multiman.

The main difference beetween this first version and the second version Multiman S is the possibility to use SUSTAIN on Piano/Clavi sounds (which is not possibile on the second version... Strangely)

For that reason, being a keyboard player, i consider this first version more appealing to play then the Multiman S.

Sonically are identical.

It comes with its original Crumar Pedal

FULLY SERVICED by pro tecnician

100% Perfectly working conditions

Very good aestetics conditions for its age (tiny little marks and scretches around and on some keys)"

SOME LOFI JAM | DIGITAKT - VOLCA FM


video upload by uh!

"In this jam, I only used the Digitakt and the Volca FM. I couldn't sync them properly, so I adjusted the timing later in the DAW.

Other than that, it's pretty simple. I start with a chopped sample and then add the drums. All the instruments, except for the chords, come from the Digitakt—the bass, lead, and pluck.

It was my first time trying to play everything live without any pre-recorded parts, and it was quite an experience. I have a lot to improve, especially keeping in time, but oh well, let's see how it goes!"

From Posters to PCBs: A Graphic Designer’s Guide to Circuit Art


video upload by Synthux Academy

"PCBs aren’t just for circuits—they can be art. In this video, I’ll break down the materials that make up a PCB—solder mask, copper, FR-4, and silkscreen—and how you can use them creatively for synth faceplates, keychains, and more.

I’m also launching a residency program and workshops for designers, illustrators, and artists who want to explore PCB design as a creative medium. Sign up for the newsletter to get updates:
