ELEKTRON DIGITAKT SAMPLING A SYNTHESIZER ~ Roland System 100 Model 101

Published on Sep 20, 2017 once upon a synth

"Elektron Digitakt sampling demo where I use a single synth as a sound source. I start off by making 4 percussion sounds including a kick, snare, tom, hi-hat and bell. Then I make a bass, lead and pad sound. I then sample these sounds into the 8 tracks on the Digitakt. Finally, I tweak the sounds and make a beat at the end.

The synth used here is the System 100 Model 101 from Roland which is a vintage analog monosynth from the 70s."

"Overall, the synth is in superb working condition. The front panel is very clean, with hardly a mark to be seen, just small blemishes. The aluminium side panels are really tidy with only minor marks. The back panel is very clean with only minor blemishes to the paintwork.

All knobs, sliders, buttons and switches are present, original and function correctly.

The unit has been fully tested, a new backlight installed, calibration procedure checked and the oscillator tuning and scaling confirmed."
