50 Oscillator, 10 Voice Synth In Action

Elta Music posts another video of their Solar 50 big ambient machine prototype      28/11/19

Earlier this month we brought you a video of a new Russian synth -the Elta Music Solar 50 prototype. The company has now posted another video and released more details.

A spokesperson told us, “Solar 50 is designed for creating atmospheric sounds, background music, microtonal music, super polyphonic electro symphonies as well as for making sophisticated complexes of extensionally dispensed tones that have random frequencies and tricky intervallic hookups. Inspired by early electronic musical developments of the last century, particularly Leo Theremin's instrument called ‘Harmonium’.Variations of sounds that you can create with Solar are really boundless.”

Here’s details from the Elta Music website…

Solar synthesizer consists of 10 voices. Each voice, in it’s turn, consists of 5 oscillators (2 low, 2 middle, 1 high) with a pitch controller and a mute button for each oscillator. Each voice is provided with an envelope (attack/release parameters) controlled by a tactile sensor.

Solar 50 has a piezo mic onboard, that let it turn into electro acoustic percussion noise instrument.

In addition, there is a GATE-ON button for every voice, making it sound constantly, and a voice volume controller.

There are two independent LFOs and a bunch of external CV inputs on board and so called PLS connector for connecting a CV source in order to control the pitch of each of 50 oscillators and to start the envelope of any voice. Patching is possible with standard pin wires that are used in Moog Werkstatt, Bastl Instruments and in many other devices. MUTE buttons let you use from 1 up to 5 oscillators per voice, tuning in for chords, thirds, fifths and other intervals or to get a clean single note.

Every oscillator has a sawtooth waveform. All voices are mixed together and then go to the effector block where you can use cartridges from ELTA CONSOLE pedal. This adds even more variety to the sound of the instrument!

Every cartridge has 3 effects, now 12 cartridges are available, so that are 36 effects in summary like delay, pitch delay, reverb, shimmer, tremolo, chorus, flanger, phaser, filter and many more!  

You can also create your own effects in special software application (available on spinsemi.com).

The effector unit is based on common FV-1 chip, which is DIY friendly.

It consists of cartridge slot, three effect parameter knobs, effect switch, and master volume.

The SOLAR 50 has dry outputs for 5 right and 5 left voices and a general mono output from the effector, where all 10 voices are mixed.

Dry outputs can be used either to create a wide stereo field, processing them through stereo reverbs, delays and other effects or for tuning as you play (If you connect a cable into a dry output, it’s signal would disappear from the overall mix)

And of course, there is also a dedicated headphone output.

The final version will include a new design and additional, yet not showed functions.  

Pricing and Availability:
Estimated price is about $800.
