Hello !
I think somone already asked more or less my question, but i give it a try;
I play keyboard and bass at the same time.
(Both hand playing a B3 Hammond, and with the monophonic fonction of gigperformer, I trigger the lowest note of my chord to go my Moog VST.)
It’s working but if i quickly play for exemple a C and afterwards E, the E doesn’t sound.
I have to wait for the C to be totally off and play aftewards a E. So i can’t play legato.
Do you have any solution or scriplet for my issue? 
Is it possible that you have set the Moog VST to trigger to the Note Off message instead of the Note On message?
No,
for exemple If i play a legato between C and a lower B it’s fine, but B to a higher C it doesn’t work.
(With the monophonic option lowest only)
Is it the other way around, when you switch it to ‘highest only’?
This is just guess-work: I don’t use GP for keys, being a guitar player, but I think, when you play legato the note-on message is being filtered away because a lower note (the B in your example) is still active.
There are other people on this forum that really know
Yes It is
It is not clear to me if you play chords and want the lowest note of the chords to be played on a specific plugin or if you want to play a bass line legato?
I want to be able to play chords and transition notes as well without the sound cuting.
Here an exemple (with a piano sound and afterwards the moog
It’s just an exemple, but this situation happens a lot and makes it unusable
So I watched what you were doing and in the case where the transition note did not play, you were still holding down the lower note.
The whole point of that Monophonic mode is to play only the lowest (or highest) note. If you don’t release the lowest note, how should the system know your intention?
Yes I press the D and I release the C afterwards, but I release it.
Doing that on any monophonic synth will play the D note after the C is release even in low not priority (At least on Moog keyboard and Behringer as well). But here no… silence.
Thing is: those keyboards are not necessarily bound to processing note-on/note-off. They can (more easily) keep track of the state of all keys. For GP to mimic this, it would have to keep a synthetic state of the keyboard, based on all note-on/note-off messages and resend the lowest (or highest) note-on for keys not already released.
Yes I guess you’re right.
But some VST instruments are able to do that, so the issue isn’t the midi keyboard.
I guess it’s not possible with gig performer as it is, but maybe a scriptlet or a VST?
Which ones?
Sampletank By IK multimedia or The legend By Synapse audio
Sigh, it’s not specifically the synth that is monophonic (though there’s no point in having polyphony in this case because) it is the keyboard that can only recognize one key at a time (goes back to the days of control voltages)
A polyphonic synth (e.g. a prophet or other more modern systems that use different mechanisms to detect pressed keys) would have a similar restriction when it comes to defining “lowest” note.
But that’s option is built in with the VST. So can’t be use with others.
I have the Legend… that is not doing the same thing as we are doing with or monophonic mode.
Perhaps you’re misunderstanding the purpose of our system.
Using the “highest” mono mode, the idea is that you can play a solo over chords where the chords are using a different sound and, in particular, the chord does not include the highest note.
The lowest mode (which is there for completeness) is the same thing to have bass on the bottom note while allowing a chord that does not include the bass note to play as well
I assure you on the legend, if you choose mono and on the back panel Lower note priority, you have the same fonction without any cut when doing “legato” like i showed on the video.
Y guess the monophonic mode works only if you are playing big chords and want to trigger the low note, but for a all set of music is quiet limiting.
Hmm, hope this is not a dumb question: Can GP do “standard” monophonic mode (only the last note played sounds)? (If not, I suspect it would be easy work for a script).
