I have already sampled much of the old 80s keyboard I have in mind... problem (until now) was just that none of the tools I had at hand could do what I wanted to do... so I have a GA4 drumkit here, a few Halion 5 patches with keyswitches there (with some clever quick control assignments to make the best use of the 8 controllers), but until February, 9th I can't implement the accompainment robot and all that.
Seems like now I can.
I always envied the Steinberg content team for having a solution for making things like B-Box or Haliotron.
As an additional note: those toy keyboards from the early 80s were not actually bad. It was just that the limited user interface options back then needlessly limited their capabilities. Imagine what, say, a Yamaha PSS-470 could do with more controls on the surface. Not a different engine, just more controls.
And this is what I like to do most with such tools. Take ancient hardware, sample it and turn it into something that fits well into our decade. Like an addiction at times.
(For my "Magic Tone 65" project I even sampled the three different static noises of the device and the sound the switches make when using them... so this may be optional parts of the patch as well...
So, thanks to Steinberg for Halion 6 and to you and Valsolim for your friendly answers.
I'm looking forward to giving away stuff very, very much as well.
Cubase 9 Pro, all the great Steinberg VSTis and quite a few expansions.
