nothing wrong…
this is why i’m going to do a getting started video - as I realised Ive not really explained how to setup a rack 
and by default its completely empty
(ok,not quite empty, if you go thru the modules (top arrows), you’ll see that actually the router module, and clock module are present…)
anyway, super quick
whilst on module a1, in the bottom panel, where its say a1:empty ,
select it (big arrow pointing right) - then the module list will come up…
you’ll want a synth, so go to the top, to get out of the ‘utility’ category, and then go to synth category, and grab a synth.
then if you plug in a midi controller, and press some keys, it should make a noise 
loopop did a good overview video of this for orac 1.0 on the organelle, but the principles of module slots is the same - so perhaps worth checking that out.
(he explains, modules, module slots and chains - and you’ll see the lemur interface looks quite similar to the organelle really)
after that my overview of 2.0 will probably make a bit more sense.
but as I say, probably at the weekend, I’ll film a getting started video, which’ll focus on how to build a rack on the remote interface.
