This thing arrived yesterday and it looks promising.  It’s from a series of toys called Beat Blenders.  They each have a different theme (this one is Hot Hits) and there are 3 different parts that you can combine and sequence into a jam.  There’s Drums, Rhythm and Melody trachs and around 5 different parts for each.  Moving the slider at the bottom moves the “playhead” of the sequence forward or back.  There’s already a few obvious enhancments that can be made.  Tempo/pitch can be expanded, volume knob and instead of the slider i’d like to have direct access buttons to the different parts of the sequence.  There may also be a way to randomly jump to different parts of the track…. if so this thing will ROCK.  Stay tuned.
