If you play an ascending scale on a string, theoretically you should press the string to the fret with your left had finger (I mean this for right handed guitarists) exactly at the same time as you pick it with the right hand. There are at least two important arguments why Pitch Bend should be used even if you pick every note. Then I really do not need Pitch Bend, so I can use one channel only, right?Ī: No. Q: OK, I do not use hammer-on and pull-off, I pick every note.
Then we are at the same point as in the question before. Although a special Legato Mode is part of the MIDI specification, most synthesizers did not implement it, so the safe way is to use Pitch Bend instead. A guitar synthesizer can emulate this also with Pitch Bend. Guitarists very often do not pick every note of a melody, but notes get different accent if they are picked, or if they are played with hammer-on or pull-off. A very important part of expressive guitar playing is legato.
Then can I use my guitar synthesizer on one channel without compromises, yes?Ī: No. Q: OK, I do not bend the strings, so I could not care less. In this case, at the start of the second note the first one will have to return to its starting pitch, or it must be shut off early. when the pitch of a note is changed, and this note is sustained while another note is suddenly started. However, this can lead to contradictions that cannot be resolved in certain situations, e.g. As a painful compromise it is possible to use pitch bend on one MIDI channel as long as the guitarist plays only a monophonic melody, and turn off pitch bend when he changes to polyphony. Since in MIDI the Pitch Bend message is common for all notes on a MIDI channel, individual pitch control of the notes for individual strings can be solved only if each string has its own separate MIDI channel. In opposite, on a guitar it is absolutely natural that the pitch of individual strings can change individually, independently of the other strings. When you play polyphonically on a keyboard and you use the pitch bend wheel, it will bend all notes what you play by the same amount. This pitch can be changed afterwards only with Pitch Bend messages. you can play polyphonically on a keyboard without restriction on only one MIDI channel.Ī: When a note is started in MIDI the pitch of the note is determined by the note number of the Note On message. Q: Why do most guitar synthesizers have an option to send the six strings on six separate MIDI channels? E.g.
#Midi guitar update
I will update this page time to time with questions whatever I recall from my memories, or whatever new questions arise. While these answers are based on my designs, I believe most of the information here is true for Roland or other devices too. I hope I can help users of guitar synthesizers a better understanding of their devices with this information. Now, as I have here a web page of my company, Panda-Audio, I want to take the opportunity to summarize this information in the form of an FAQ. Over this period I answered thousands of questions from users who had some difficulties to understand certain features or behavior of their devices. I developed several generations of devices from the Shadow GTM-6 / SH-075 through the Blue Chip Music / Terratec Axon until the Fishman Triple Play today. I spent most of the last thirty years designing guitar synthesizers.
