A quick review of the jamorigin software mentioned by the OP:
Tried it for two hours as a standalone and as a VST insert testing with two guitars (Strat and Tele) thru a clean pre. Various pickup combos used. 64 sample buffer.
Once you get it into a DAW, the thing falls apart…particularly if you are recording a MIDI track. Way too many false notes, regardless of UI settings. Note placement too far off from where it was played. Post quanting actually made it worse. No ability to reset the UI without trashing its Pref folder. No ability to quickly set note recognition range sensitivity to conform to the range of notes to be played…something that might improve the incredible amount of false triggering this thing generates.
An interesting toy for iPad user. A good initial first effort, but certainly not a $100 app at this stage of its development. $30 tops, in it’s present state…and only if you’re bored to tears.
