Sean which store did you visit? We will send someone in there to teach the staff how to use this important feature. In their defense, it is not something that gets demoed much in stores (unfortunately). They are afraid to leave the microphone unsupervised, if get my meaning). But we’re willing to make that training happen.
Not only can you plug a Microphone in for the Vocoder but you can use it as a tempo source... place that Mic in the drummer’s kick drum and now they are the tempo source for your Arpeggios, tempo driven Effects, etc, plus they can become a modulation source in your synth engine. When working the Mic will sound great through the instrument... it has its own channel, it’s own Dual Insertion Effect, and Routing situation.
To assume it doesn’t work is NOT good enough. We, at Yamaha, want to replace your instrument if it is not working properly (although we don’t think that is the case). And are willing to send someone to that store location to show that staff how to support the product... so that on your next visit they can show you. And if it is true that both your instrument and theirs are defective, then, by all means, we want to replace both! asap!
Let us know, thanks...
Still no luck--just a loud hum when we turn on A/D and turn the gain up.
One other question: TS versus TRS? Are you certain about TS versus TRS? Very important difference.
TS = TIP SLEEVE (looks like regular signal cable 1/4” jack)
TRS = TIP RING SLEEVE (the male connector has a second black band) = ng
