Elta Music Solar 42

Continuing down the path started by the Solar 50, Elta Music's new Solar 42 is a refinement of their ambient Machine concept: a thoroughly explorative synthesizer with increased emphasis on melodic playability. While Solar 50 was a massive, 10-voice drone synthesizer with a whopping 50 oscillators, Solar 42 offers a slightly more streamlined set of eight voices but with more variation among each of them. For starters, voices 4 and 5 feature 1V/Oct pitch inputs—something that was entirely absent from Solar 50—supporting melodic pitch control via sequencing or external controllers. Voices 1, 2, 6, and 7 provide the same flavor of swarming drone oscillators from Solar 50, but now voices 3 and 8 offer noise generators, FM, and other ways to coax more timbres out of Solar 42 compared to its predecessor.

Solar 42 features expanded controller and modulation features, including an updated touch interface and a new five-step sequencer. Now featuring 12 touch points, a joystick, and switch keys for each of the drone oscillators, you can easily trigger and control as many or as few of the Solar 42's voices as you'd like. Also returning is the famous Elta effects cartridge slot, offering independent and interchangeable effects for the left and right channels. If you're seeking an ambient synthesizer like no other, Elta's Solar 42 is the ideal vessel for your sonic journeys.

SOLAR 42 sound demo part 1
SOLAR 42 is a unique experimental electro-music instrument, an analogue microtonal ambient drone machine. It will inspire you to find a new and spontaneous approach to composing music. No midi, no presets.

The instrument is oriented for live performances, creating film soundtracks, theatre soundtracks, atmospheric sounds, microtonal and background music. It is an improved version of the older SOLAR 50 model. The instrument was inspired by early electronic musical instruments of the 1920s and 1950s, notably Leo Theremin's «Harmonium» instrument, as well as science fiction film soundtracks.

The SOLAR 42 does not look like a classic synthesiser, which may confuse the user as it looks very complicated. In fact, it is easy to use. It has 8 voices as separate blocks, a mixer with pan and double effector, and various CV blocks.
