I bought this trackball mouse the other day as it was on sale (and still is as of this post) It looks to have a unique? Vertical layout. Haven’t received it yet, but curious to see how it will go velcroing it to my guitars! I imagine I’ll be tied to a computer screen while using it for recording (I may never really play guitar live anyways) but I’ll let you all know how it goes! I realize it’s not midi but might be an alternative of sorts to controlling VSTs etc. Amazon.com
That ATEMP MC1 (Its sort of a mod wheel/pitch bend wheel unit) I linked earlier doesn’t ship overseas but sounds like they are looking for someone to produce/sell them overseas I guess!
