QuNexus out the door - Software up

Hi Backers & Friends,

We shipped the first batch of QuNeos yesterday. V 1.0 of Software Editor (OSX, WinXP and Win7), Documentation, and the OSC Bridge are available for download: at:

It is the first controller that has made me like keyboards. Everybody at KMI did stellar work and we all feel it turned out pretty darn great.

We will keep shipping units regularly until you all have your QuNexus. This will take a couple weeks as we are inspecting and several people are playing each one. 

I would really appreciate you being wonderfully patient just a bit more - delayed gratification and all that - by not deluging our sales and accounting people with "When will I get mine?". I appreciate your excitement but this only slows us up. If your address has changed let us know. 

So thanks again for your support and we really want to hear some new music after all this. Send us what you are doing and record the first sessions. QuNexus is an instrument that will grow with you, but there is never going to be that initial crazy experience of Wow as the first time you fire it up.

Hi Backers,

Happy to report the first 55 QuNexi are FedExing their way here. Hundreds more will follow this week as we ramp up production. 

We will inspect and play each of the units in Berkeley to make sure they are perfect. Then we will send them to you in the order of your backing date. So early birds should start to see them next week. 

We will be including a toll free number with each unit so you can call us directly if you have any questions or concerns. We want to make sure you are totally satisfied and excited by this new instrument. 

Thanks for your support. 



Hi Everybody,

We are postponing the production ramp up until Thursday. We have received two batches of 10 units each and they are very very close. But we have some stringent demands on performance and we need a few more days to dial this in.

We are talking about a couple of a thousandths of an inch difference that we are after and, in fact, most people would never notice. But we have hit this performance objective in all of our other products and we will do so again with the QuNexus. 

Thanks for your patience while we obsess.

- Keith
