Mark Mosher has some interesting details on the Waldorf Rocket. Here's one in particular that stuck out to me:
8 Oscillators Mainly for Unison – But There Is a Special Case…
Special case: If Sawtooth is selected and the poly saw mode is active with a maximum value of the Wave parameter: With maximum setting of the Tune parameter you will get an unisono mode where all 8 oscillators will play the incoming MIDI notes. This is no real polyphony but will allow playing chords.
Seems to be some conflicting information on the price of this thing, but anywhere under $300 would be a great deal.
