Hi,
I agree with you : If you don't release all the notes at the same time and it is considered as a new chord => It's interesting. But, nethertheless, in order to play another chord I MUST release the first notes in order to press the new notes belonging to the new chord. I don't know how processing in another way. At this time, the chord is changed. I confirm it's not a normal situation.
I precise clearly : It's not correct when all the notes are released. If only one note is released, it's interesting in fact that LS modifies the current chord (you will obtain certainly a chord with the same root. ie I press C E G B a C7 chard is played then I released B and a major C Chord is recognized)
But in my situation : I press C E G B => a C7 is played. I release all that notes to press G B D => During a brief instant a chord totally different is played before the major G chord is recognized.
Moreover, I play with a Roland midi accordion. Maybe you don't know but with an accordion, you play a chord with a single touch. One touch is a major C, another a minorC and a third a C7. For playing a walz for instance, I use the left hand to drive both the arrangeur and give the tempo. So, for each measure, I play the bass note and the chord note Cm two times for the other time stamps. With this behaviour, an amazing chord is heard between the second and the last time of the measure.
To ending, I think that in at least one situation could be met : I press the chord, LS played the chord and during the following measures I can use my left hand to play a embellished melody part in the right part of the keyboard. It is often used too when you have time to change a volume setting on the mixer table, drink a beer, or whatever else.
So, I confirm : When only one note of the chord is released, it could be interesting for the musicians who let his left hand without moving. But, if all the notes are released, LS MUST keep the current chord as the correct one and must wait another note on event for changing the chord.
Apparently, you have not the same behaviour on your side. When you play a C7M then a C7, I understand it's interesting. But more oftenly, you have to play a CM then a Am7 chord. Do you think it's correct if LS add a Gdim chord during a brief period between the two chords actually played ?
Thanks for your answer.
