I am a guitarist and therefore if I could use accurate Guitar midi rather than my Arturia Keylab Essential 88, I would be able to compose far more rapidly. Nearly all the music I have written about 30ish pieces have been via the guitar. I am using Playground Sessions to improve my keyboard skills as I am really a one handed player, knowing the keyboard and music quite well, but I have never mastered the keyboard like I have the fretboard. In the guitar world I have talked with Leon Todd in Australia, Alex Hutchings UK, Jack Thammarat in Thailand and it has been suggested by them that there is yet to be good guitar midi that matches the keyboard which is why I use the Arturia. Do any of you use a Guitar Midi or would you like to? The two out there are https://playjammy.com and http://www.yourockguitar.com. The pro musicians have said that the tracking with the pickup style add on to a normal guitar is just not successful. Its less than good made by Roland or Fishman. Alex who helped pioneer the Boss version does use anymore and rather developed the synth pedal with them. So does anybody use a guitar midi, it is probably going to be my next gear purchase!
I have also found Jamstik which Bill uses from Chords of Orion and apparently this tracks well. Yourockguitar website is no more and the last entry on fb was 2017 so I suspect they are no more.https://jamstik.com/products/studio-midi-guitar listen to the violin piece its super good.
I am using Fishman TriplePlay wireless midi guitar controller. It is rather good but the tracking does make mistakes too (extra notes get generated or the timing isn’t quite right). So, some cleaning up and nudging of notes is involved in most cases after recording a part.
I use the Fishman with the bluetooth connection.
I works pretty well but as others have said there can be tracking issues that caused stray notes.
Usually I put on a new set of strings and that helps the tracking.
I find this method of MIDI works well when there is a complex virtual track am trying to record as I havent mastered the keyboard yet.
