OK, sorry I didn’t understand first time due to the sentence.
It is not handy to set this externally. I use a Linnstrument and it’s well made to produce vibratos and slides via pitch bend messages. To get the good note when sliding it is needed that all controlled synths are set the same. For the CV/Gate synths that’s set in my Cirklon and the maximum amount is 12 semi-tones, what I like very much for the keyboard bender wheel/joystick in the same time.
May it be possible in the future (or in the circuits) to change this fixed amount ?
