Good job of troubleshooting... I assumed you have tried other triggers into the kick drum input and found it is dead. This leaves the problem in the "brain". Look in your manual for anything to do with sensitivity of the kick drum input. It is likely all the inouts are sampled and digitized by the same A-D convertor via a multiplexor switch. I was unable to find the schematic of your unit so I downloaded one for a Roland TD8. Often the different companies rob designs from eachother so one can glean methods from a different brand. As expected the inouts are conditioned and then go to a MUXX chip that samples the input. The signals are conditioned before going to the MUX by a limiter and before that there is an RF bypass cap on the input. IF you might have had a static discharge, that capcitor(s) may have shorted rendering those inouts dead. This is what I want you to try:with a suitable cable I would like you to pulse the kick input by momentarily connecting a 9 volt batery to it... try both polarities. If NEITHER polarity fires the kick, then I want you to take an ohmmeter and measure the resistance of the input. The Roland schematic has coupling capcitors and if your brand has similar circuits you should see infinite resistance... if you find it very low, say 100 ohms, probablly the RF bypass cap at the input is shorted. These will be surface mounted caps and you need to be a bit adept at electronic repair to replace them. Essentially I believe you will find a failure in teh interface ckt where those inputs come in.

Same problem. have you figured out how to fix that?

I have the same turntable, and sadly the cartridge is proprietary and unable to be changed. However, you can still upgrade the sound quality by replacing the stylus to a higher quality needle. I did that for about $25 and feel better about playing my precious vinyl. The biggest problem to this turntable is the lack of anti-skate. That's very bad...

did you solve this? I have the same problem - help!

You can buy a new stylus from IONhttp://www.ionaudio.com/products/details/ict04rs

Have you tried the guitar in another Mac/ PC? If it still doesn't appear, there may be a problem with the guitar electronics. If you bought it new, take it back to the shop/ send back to the vendor.

Have you tested your amplifier and speaker for operation with other device. This unit needs to have a decent sound system connected. Do you get sound using the headphones?
