To me, this step is logical. Someone has identified a possible market where they can get OLLT (objects looking like trumpets) into the hands of more kids than would be possible with metal horns. If the concept flies, there will be a "WallMart Avenger" OLLT blister packed for $59.95 within 5 years. Grandmothers and aunts looking for a cheap birthday gift for their musical relatives will buy them with no further thoughts - like all of those cheap miniature keyboards that have no use except to make noise.
My interest in a Tromba or pTrumpet is not affected by this "development". I am not looking for the lowe$t common denominator.
If Alison had used the pTrumpet at her night of the proms concert, I would have been really impressed. With the marketing video, the event was reduced to "$€X $€LLS"!
