Hi,
this is my first post in this forum, and I’d like to share with you my workaround to implement a pedal sustain in the AK/A4.
You will need a pedal sustain plugged in an external midi keyboard.
The sustain in every MIDI environment send signal to the CC 64.
The CC 64 in AK/A4 is used by the performance knob F.
All you have to do is to configure the F Performance Knob with the release of the Amp envelope, giving it a +127 depth ad assigning it to the track you will use for the sustained sound.
Now if you connect AK/A4 with the external keyboard via MIDI or USB the sustain pedal will do the job! Excellent!
I know that this is not a perfect solution because you will need a second gear to obtain this trick, but I read some people complaining about the lack of pedal jacks in these awesome gear and if you necessarily have to use a sustain pedal to play some polyphonic organ/piano style patch this is actually the only way to achieve this goal…
I hope somebody will find a simplier way.
