Apologies. I think it’s a Keylab.
I really empathise with all the enthusiasm here, but please go to Arturia forums for Astrolab and the Facebook group, and read on all the things that don’t work.
There are some critical bugs, that Arturia is not fixing right now, and that makes me sad to part with my A61 for now.
What are the bugs?
For example if you copy a lot of presets to the Astrolab, the connect app doesn’t work and just crashes every time. The whole OS becomes laggy and unresponsive, you can’t delete samples from the internal memory and the only way is to get a new unit from your retailer, I recommend reading what I wrote about.
This is not hate, but just a sobering reminder 
Another pre-purchase q, answered by Decksaver: “We will most likely do a cover for this next year.”
If anyone sees any cases/ideas for this one let me know, as I’m sure I’d want to cover up those capacitive encoders/screen.
Bought the astrolab 4 months ago, and today sold it. Eagerly waiting for 2.0 fw that will eventually come and fix bugs, good luck to everyone!
Will be eyeing an 88 on the second hand market, because it being x2 the price of the 61 is bonkers 
I do something similar with my Hydrasynth Explorer, when I don’t want to take my Novation SL61 Mk3 controller. I have a dedicated midi control patch, where all of the synth layers are set to 0 volume. I imagine on the AstroLab 37 I could do something similar - just create a silent patch in Analog Lab and transfer it across.

So simple. So elegant. Why have I not thought of this!

Yeah I’ve been thinking about who the A37 might be just perfect for. Most of us probably think of it as a companion in a larger setup, but honestly I could see a lot of people making music with just a sampler or drum machine, where they want a little bit of synth sounds in the mix. Meaning, the art of synthesis isn’t primary for them and maybe sound design happens mainly with samples.
For that use case, the A37 is pretty much the ideal instrument to add to the setup because it doesn’t force you to commit to a certain category of synth sound.
I made a DT2 track with sounds from the A37, all sampled and nothing sequenced live from the A37, and it’s been an eye opener for me (mainly in how I’ve been thinking about the DT2 the wrong way until now).
So, a long way of saying: just because you can’t do a lot of synthesized sound design on the A37 hardware itself doesn’t mean it can’t be used for a lot of sound design as a sample source.
And with the A37 and the Peak, you arguably have every sound you’ll ever need (famous last words, of course 
).
Here’s the DT2 performance in case you’re curious - all synth sounds are from the A37.

Astrolab 37 with the Mellotron Micro Module. A complete wall of sound in a tiny form factor.
