Hi.
Possible workarounds solution down the line.
It's not possible to assign the midi CC64 to anything in Mellotron V.
I assume it's because midi CC64 is a reserved parameter in other Arturia applications.
And in Analog Lab you have Sustain on/ off function for Multies.
But precisely becasue of this, i also think midi CC64 should work in all applications in one way or another.
I think a modulation matrix that include the sustain pedal - or a button that by user choice can switch the Midi CC64 to control either The Macro Release or a Hold note as the samples can be looped in Arturias version - should be added in Mellotron V.
The added Release and sample loop functionality does make an added sustain and hold note functionality make sense.
It should not be that hard to do. It's a more than resonable request and assumption that the functionality would be there allready. I prefere to look at this lack of sustain pedal functionality as an oversight from Arturia.
As it is now, then it's possible to either have a pedal that use a midi CC, that you can assign to Mellotron Vs controls and use it to control the Release in the Advanced window, to create a Piano style sustain.
By default Factory config then midi CC83 is set to control the Release.
Also you maybe have options in your DAW or whatever to assign even midi CC64 to the Mellotron Vs Release by controlling the Macro Release automation parameter.
Or perhaps a way to map Midi CC to another midi CC like Midi CC83.
You can create different Midi configs.
And you can also use a Mellotron Macro.
Just find a way, that works for you.
But yes, it would be much easier, if Arturia made a solution to use the midi CC64. It would match other Arturia applications to do so.
I have different options to make a Piano style sustain by using the above mentioned workarounds.
