Aleq project should be dedicated to the use of modular synthesizers. So, no keyboards, no desktop ?
Noway, "if it's sound good, it's good." (Duke Ellington)
So in this particular project, why not accepting some "all in one" synth (Even with a keyboard ?!).
I have several synth that are not eurorack modules. Not really interesting to speak about, there are a lot of good video on the web. But 2 machines can be more interesting, maybe.
And both are "modular" (in fact, semi-modular...) :
A RSF KOBOL, Expander I and II, with a small add: a joystick.
I never see any info about this stuff on the web. I was buying the two expander, and this joystick was included, so...
But it uses two 9V batteries, with no ON/Off switch, and you have to disassemble it to change the batteries: not effective ! In addition, it seems broken: needs some investigation. Or just leave it like that.
Because there is another interesting machine, with 2 joysticks:
An old and dirty ELEKTOR FORMANT. Very long time ago, a friend had given me it. At that time, I had no money, so I had fixed it as best I could. (Some components had rusted...).
I had abandoned it for a few years, and now it's time to check it.
And except some pots and switches, it works !
