Hello everybody! this certainly is one of the best communities around. and midibox is just great stuff to deal with. yes, i've also caught a midibox bug ... well, i'm glad so, i'm getting into building a couple of things. SID being the first; still got some wiring left + pic burning... i will present it here as soon as it starts producing some sound. the other project is a midi merger. i've got the parts, box is on the way - everything clear & set; main motivation is to have a simple merging for the purpose of playing sempler (mostly live) from both the electronic pads, and a keyboard. still i think it could become even more handy (especially on stage, also for purposes of further routing) if it had both inputs available as thru's (unemreged, that is); my question is: what do i need to get this - would it be possible to simply hardwire an out from each in (after optocoupler), or do i need a thru module for each? another thing: would it make a problem if i duplicated out - hardwire another parallel port to existing out? thanks, and sorry if this is stupid to ask.
