Setup and maintenance
-
The 921 oscillators require calibration using an oscilloscope; a persistent glitch in the SUB mode may need further adjustment or troubleshooting.

Attainable Synth History
Look, if I had an extra $35k lying around, I’d 100% have the Moog System 55 or iiic. Behringer does some stupid, edgelord-y things that you just can’t excuse, but the democratization of quality synthesizer accessibility is an undeniable win for musicians.
Being a working composer, I need tools that don’t have too much overlap, and some that break me out of the typical way we see music, so I love using it without a keyboard and seeing how I can make drones more interesting and musical. And since virtual orchestras take up so much RAM on my computer, it’s nice to not have to rely on plugins for synths to save the strain, and let your hands/ears do the work.
I’m looking forward to adding some FX modules to the bottom row.
