Thx Jim ! There is the service manual ! Mmm I’m getting the Midi in expansion for Es9, and it should be able to recieve Midi, send it to the DAW, which can send CV out through ES9 ? But Maybe there’s latency then ? I’ll look into it more closer. I wonder how the Midi signals from the Elka will be shown in the ES9 ? The Elka has 2 midi out, and is poly with aftertuch - and you can split the keybord in 6 parts - so there’s possibility for assigning funtions to different modules in my rack. Not really MPE+, but on it’s way. I could bot find a good alternative in any new keyboards. The Haken Continium is out of my reach, and not really a keyboard.
