RP355 USB functionality

ultomatt · December 2009

I've just recently purchased an RP355. I'm a long time Digitech user, having owned and used an RDS1900 for nearly 20 years. This is, however, my first effects unit that is connective through the USB port to my computer. I can see it's going to make things a lot easier, but there is but one hitch...

I've successfully dl'd X-Edit and the RP355 drivers. I've connected the RP355 through the USB port, but am unable to hear any audio through my computers soundcard (Audigy 4 Platinum). I set and reset all of the audio driver settings I could find, but none produced a peep out of the computer. Am I mistaken in thinking the audio can be recorded and played back through the USB ports? I'm good with just plugging the analog out from the RP355 to my analog mixer and then to the computer...but it seems pretty old school if that is the normal way of recording and/or playing back music.

IIRC, when you are using ASIO drivers you can only have one device active at a time. So, you can record from the RP355, but you must also then play from it. In other words, select it as both the in and out, as if it were a sound card, and have you monitor speakers hooked up to it.

Thanks,

I've tried all the combinations of input and output I could find, and can't get a peep out of the RP355...not a crackle or a pop. Headphones off the RP sound fine, so the audio is there, but I cannot get the drivers configured properly to put the music through the speakers. Thought it might be a problem with the cable, but I tried a 2nd cable and both seemed to work properly. USB1 doesn't seem the best for streaming audio...just thought it curious that the unit doesn't have USB2.

Not sure what you mean by hooking up the speakers...I assume through the USB port, i.e. using the driver software to reroute the audio from the RP...since there is no output for speakers on the RP. I've tried again tonight and no luck. The drum machine sounds good on headphones, but no joy on the speakers. Gonna likely move on to analog to the computer.

Did you set the XLR AMP/Mixer switch to mixer? I have my computer speakers plugged into the headphone jack. It doesn't sound that great because my computer speakers suck but it works. I just got my rp355 and don't have any cords to run off the xlr outputs yet but this works for now.

By \"hooking up the speakers\" I mean. assuming you're using powered computer speakers or powered monitors, connect the speakers to the headphone out jack of the RP 355.

In your \"sounds\" Windows control panel, make sure you have the RP355 selected as both the in and the out. Then, you should be able tomplay something from the computer and have it go to the RP355. If the program you are playing form has an audio preferences menu, you also want to select the RP355 as the output device from that menu.

Thanks for the advice...I'll give it another try this evening after I get home from work. Sounds like the USB port isn't really used for outputting sound, since the avenue to getting sound appears to be the headphone jack. And yes, I have powered computer speakers. The Digitech RP355 drivers are selectable as In/Out, which is how I have been setting the audio when I've been testing to see if it would work, i.e. attempting playback using only the USB connection through the Audigy 4 Platinum soundcard.

I'll report back...and thanks again for all the good advice!
