ProKeys Sono 61 User Guide

Troubleshooting

ProKeys Sono is a high-quality digital piano that has been tested under a wide variety of conditions to ensure trouble-free 
performance . In the event that you do experience difficulty with your ProKeys Sono, this section provides tips to help resolve some 
basic issues that you may encounter .

Problem

: My ProKeys Sono keyboard suddenly stopped working after having performed fine since installation .

Solution

: Close any music applications you are using, switch ProKeys Sono off, and restart your computer . Once your 

computer has completely restarted, switch ProKeys Sono back on and try again to see if the problem resolves . 

Problem

: I have connected a sustain pedal to my M-Audio keyboard, but its operation is reversed (i .e ., the notes sustain when 

the pedal isn’t pressed, but the notes stop sustaining once the pedal is pressed) .

Solution

: The polarity of the sustain pedal is calculated by the keyboard upon startup . When ProKeys Sono is powering 

up, the sustain pedal is assumed to be in the OFF position . It is important that the sustain pedal is not pressed down during 
startup, otherwise its operation may be reversed .

If you would like to intentionally reverse the polarity of your sustain pedal (i .e ., notes are sustained when the pedal is up; notes 
stop sustaining when the pedal is pressed), hold the pedal down while the keyboard is being switched on .

Problem

: When playing a virtual instrument loaded in my music software, or when attempting to monitor my microphone or 

instrument input, there is a noticeable delay before I hear any sound .

Solution

: This delay is known as latency, and it can be adjusted by changing the buffer size setting in your M-Audio Control 

Panel . The goal is to set the buffer size as low as possible without experiencing artifacts in the audio . Faster computers 
generally allow for smaller buffer size settings, and thus less latency .  

When monitoring signals from the Microphone, Instrument or Aux inputs, you can also avoid this problem by using the Direct 
Monitor knob instead of monitoring through your music software . See the “Using Direct Monitoring” section in the  
“ProKeys Sono Audio Setup and Controls” portion of this User Guide to learn more about direct monitoring .

Problem

: I have connected the keyboard to my computer with the USB cable, but I cannot locate the ProKeys Sono USB 

keyboard in my software’s MIDI devices dialog box .

Solution 1

: ProKeys Sono may not be receiving enough USB bus power to function correctly .  Try plugging ProKeys Sono 

into a different USB port or a powered USB hub connected to your computer .

Solution 2

: In Windows XP, ProKeys Sono will appear as “USB Audio Device” if the optional drivers have not been installed . 

Select “USB Audio Device” as your audio and MIDI input and output device . 

Problem

: I connected ProKeys Sono to my Windows computer and noticed that a question mark appears in the Windows Device 

Manager under Other Devices > M-Audio DFU . Does this indicate that there is a problem with ProKeys Sono?

Solution

: This behavior is normal and your ProKeys Sono will function normally as a class-compliant device (i .e ., without any 

drivers) .  Installing the ProKeys Sono drivers extends the keyboard’s functionality in various ways (i .e ., multi-client support, 
support for qualified versions of the Pro Tools M-Powered software, and allowing large SysEx transfers) and should resolve 
any “DFU” related messages that appear when drivers are not present .

Problem

: My synthesizer always recalls the sound next to the program number that I have sent to it from ProKeys Sono . For 

example, if I send a program change with the number 40 (Violin), my software loads sound number 41 (Viola) . 

Solution

: Some General MIDI modules count their sound patches from 1 – 128 instead of 0-127 . Both methods are 

common . As a result, there may be an offset of +/-1 between the program change number sent from the keyboard and the 
recalled sound patch on your module .
