Can Hapax be used as an editor for old digital rack synths?

I have a rack of old synths like the Kawai K1r, the Korg Wavestation SR, the Roland JV2080 etc. Can I write instrument definitions to be able to use my Hapax to create and edit patches on these synths, or would I be better off with something like the Electra One?

Not really. You’re basically limited to standard CCs (14bit and NRPN resolution doesn’t work correctly from Hapax) and the assign page (having CCs mapped to a Hapax encoder) is limited to 8 mappings. Ok for modifying a few parameters on existing patches, but not for building patches from init.

That clears things up, thank you!

Electra One is exactly what you’re looking for. There’s no alternative as far as I know.

Just to put in my two cents. I do this at the project level. I do it with synths that don’t have preset memory (nts-1) and I started doing it with my synths that do have preset memory because I like the workflow (I just make sure that preset 1 is an init style setup).

So what you can do is put all the CCs into the instrument definition file, and add them to the automation section with null values. That way they show up right away when in the automation screen. Then you can set the default values manually as you dial in the sound you want, and then save the project.

It’s probably not exactly what you want but I’m just putting this info here in case it helps someone else.
