F.A.Q.
Q: Can I buy a ZWI?
A: The ZWI is a D.I.Y. project. If I were to sell ZWIs, I would not be able to offer any
technical support. There is a chance that I may have some spares at ZAKU shows, which you
are
welcome to buy with the understanding that it may take some technical know-how to maintain
and
operate it.
Q: Where can I get a ZWI pcb?
A: You can get a free PCB at any ZAKU shows. The gerbers will be added to the ZWI github
soon if
you would like to make your own. Once we print some more shirts, we'll mail a PCB with any
shirt orders.
Q: Do I need a reflow oven or rework station to build a ZWI?
A: Only a soldering pen is required. All components are through-hole. Please use lead free
solder.
Q: Does the ZWI have it's own audio engine?
A: Yes! You can find a block diagram of the syntesis structure in the resources bar. It puts
out MQS audio through the 3.5mm jack, or 24 bit audio over USB.
Q: Does the ZWI support MIDI?
A: Yes, but only basic commands for now (Note on, Note off, Breath, Pitch). All MIDI is sent
over TX channel 1.
Q: How do I power the ZWI?
A: The ZWI powers over USB. Use whatever 5v USB power is handy! Your computer, a wall wart
adapter, cigarette lighter adapter in the car (only play ZWI as a passenger, and ideally in
a Toyota MR2 AW11), or a rechargable phone power bank, etc.
Q: Where can I learn more about wind synthesis?
A: Patchman Music has an excellent FAQ linked on their homepage. The Facebook page "Wind
Controllers / Wind Synthesizers" is a very helpful community. Listen to T-Square, The
Rippingtons, and Michael Brecker.
