I had a lot of frustration at first, too, when I got my Artiphon Instrument 1. I am an Android user as well and I have a nine year old Motion Computing LE1600 pen pc as well as a more powerful and newer Core2Quad desktop pc and I am using Windows10 on them both. (I am awaiting delivery of a new Surface Pro 4, however, because the old sound card and the old display settings on the LE1600 are too limited and the Instrument1 and the Kontakt 5 software do not function very well on this old hardware. It works fine on my Core2Quad desktop pc, however.)
I have worked on it for many hours to get it working and here is how I got sound out of it on my pcs:
Turn on your Instrument 1 making sure that its battery is charged.
Make sure your Instrument 1 is connected to the pc.
Make sure the pc sound icon in the taskbar is showing Speakers (USB) 85% which means that the Instrument 1 is set to play sounds itself.
Set the Instrument 1 to the guitar setting, the first icon on the instrument.
Set the volume to halfway.
Start Kontakt Player 5 on the pc.
Bring up Kontakt Factory Selection (presuming that you installed this beforehand under Add Library)
Go to Options (the little gear icon in the upper right hand corner of the Kontakt Player window.)
Click on Audio. Maker sure that Instrument1 shows in the second little window on the upper right part of that window.
Click on Midi. Click on Inputs. Make sure that Inputs has Instrument1 show PortA in the status box. Click on Outputs and make sure that Instrument1 shows up under Device Name and that the status box is set to "On"
Now Click on Band under the Factory Selection Instruments window and see the grouping of instruments listed there.
Choose one of the instruments. For example, double click on An Upright Bass.nki. A black window will open briefly then disappear and a instrument window will appear on the right hand side under MultiRack. It should be named An Upright Bass.
Now for the tricky part: at this point if you have followed all the above instructions, you should see Output: st.1 under the name and under that MIDI Ch: [A] 1. (as well as the other boxes called Voices: 0 Max: 32 and Memory 1.79MB.) When you pick up your instrument and strum the black nubs, you will not hear anything! Yeah! Go figure! What I have to do is change the setting under MIDI Ch: [A] 1 by clicking on it , go to Port A [Instrument 1] and choose 2 to set this to 2 instead of 1. Now pluck the black nubs and you should hear a deep bass sound! But only on one nub! What to do!? Go back to the listing of instruments and double click An Upright Bass.nki again! A second window with the same name, An Upright Bass, will come up. Change the MIDI Ch: [A] to 3. Pluck the second nub and you will hear the second note of a double bass. Go back and repeat the above setting the third window to 4 and do it one last time setting the the fourth window to 5. Now you should hear the four strings of the double bass as you pluck the first four black nubs. You can now also change the note by pressing on the fret on the string of the nub you are plucking.
Once you get this working, save these settings to a file with your name on it so you can come back and use it at another time. For example Stephan Double Bass.
I did this for several instruments and I am now able to play and practice and learn the I1.
I had to figure this out myself because the instructions on the Artiphon website were only partly clear. At this time, I have only tried Native Instruments Kontakt 5 player software. I have not yet been able to figure out the Audio Evolution Mobile on my Samsung Galaxy S6 android phone yet although I did install it because another gentleman posted here that he got it working. So I’ll keep trying.
I hope this helps you, Stephan. Good luck. I hope you will be enjoying your I1 soon.
