In listening to the Gofriller demos, and reading the various comments in the responses, one of the secondary issues that has been mentioned is the use of portamento in the various demos. I agree with other's comments that the portamento choices in some of the demos seemed unnatural. In a quick review of Gary's website there did not seem to be a tutorial on slides/portamento.
As a long time strings player (bass) it strikes me that a tutorial about slides/portamento/shifting/bowing technique might be of some use to the members of the forum. There are certain bowing/left hand position shifting combinations that will, by definition, create slides between notes (Many slides performed especially by new or intermediate players are the result of not yet having mastered left hand/right hand coordination.). Similarly, there are other techniques when portamento will be highly unlikely.
Over the last few days I have been giving some serious thought about possibly attempting to write such a tutorial. Is this something that would be of interest? Please let me know your thoughts.
