Matryoshka 1.2.2

• "update failed -5" on Return to official V15 is now explained in plain words: the FM-1 was most likely set up by
  M-VAVE's Official Open, whose start-up software differs from V15's, and nothing was changed. Putting Official Open
  back or going back to V15 from the Install panel comes with a later firmware; the README says why Official Open will
  not come with Matryoshka (its sound engine is M-VAVE's own, not open source).
• A new community patch, Sol 29N, recalls the Elta Music Solar 42N in stereo: three saw drones that swell on their
  own pulse generators (FX, LFO and EDIT switch them), two noise voices with sample & hold (ARP), two keyboard voices with
  a morphing wavetable, a sub and pulse-width modulation, a 5-step line on PLAY, a distortion and a band-pass filter per
  side swept together, a long reverb and a ping-pong delay. It plays on the FM-1.

The FM-1 firmware is unchanged from 1.2.0 (matryoshka-1.2.fwsc, attached to v1.2.0).
