Edit: After reading this post, see here for the improved emulator version 2 and challenge
I was intrigued by Omri’s “ultimate drone machine setup” video in which he builds an emulation of the ELTA Solar 42. I am a sucker for a good ambient drone scape, so I decided to take a stab at creating my own emulator that more closely matches the sonic capabilities, workflow, and limitations of the hardware. Not exactly an easy task because the Solar 42 manual leaves out a lot of implementation and behavior details, and I could not find many reviews of the actual hardware.
Here are the only two videos I found that do any type of hardware walkthrough, and I think they both leave out a lot of details.
Never-the-less, I think I have come up with a decent emulation of all 8 voices, the stereo mixer, the sequencer, the LFOs, and the filters. I also laid out the Patch Master user interface to be similar to the hardware, and I include a patch bay with all the inputs and outputs. The UI and patch bay are completely isolated from the actual guts of the patch, so it should be easy to work with.
I opted not to attempt any emulation of the joystick, momentary drone buttons, piezo mic and envelope follower, or the touch plate keyboard with its many capabilities. You can patch in some of those capabilities via additional modules and the patch bay. Better yet, include your favorite MIDI controllers.
The patch includes documentation that breaks down all the differences between the emulator and hardware in more detail.
While building the emulator I decided to use as much Venom plugin as I could as long as it didn’t complicate things unnecessarily.
Here is a demo patch and video using the emulator. The Solar 42 is designed to be “played”. But this demo patch is fully auto-generative. In order to randomly fade in/out the 6 drone voices, I added some Bernoulli Switches that aren’t part of the emulator, but then, that is what the patch bay is for.

Updated version 1.1 with a bug fix is here.
I won’t hold my breath, but I would love to see what others can do with the patch.
