The adaptor for the SPD-20 is not 12 V ac (Altern Current) the SPD-20 need only Altern current (12V AC)
if the adaptor is 12 v cc, the internal circuits can not made +5v , 0, -5v
for simetrical operactional supply.
And Spd 20 show "Analog test err" and "batery low"

I am not understanding the problem. Does it make any sound at all? If so Does the unit make all the sounds it was programed to do?

Example: Enter the following x variables, and determine the sample and population standard deviations.
x = {1,2,3}

• Press [DATA] and begin to enter the data as indicated into the L1, L2 or L3 lists. To input a data point, type the value and press [ENTER]. Press the down arrow key to move on to the next data point.
• Press [2nd], [STAT], and then choose 1-VAR.
• For the "DATA" option, choose the listname the data is stored in (L1, L2 or L3). For the "FRQ" option, choose "ONE" since this data does not include a frequency list.
• Arrow down to "CALC" and press [ENTER].
  
  Answers should be as follows:
  3:Sx (Sample Standard Deviation) = 1
  4:sx (Population Standard Deviation) = 0.816497
• Press [2nd] [MODE] to exit STAT mode.

if you have the samples in .WAV then you will have to IMPORT them, because SPD-S can only play .SPD files (import will convert from WAV to SPD).If you have produced your samples with your SPD-S (via mic or line-in or PhraseMaker) then they are already in .SPD-format and can be assigned without importing.
In this case you just have to assign a sample to a pad, by pressing CARD ("card"=lit) you can assign samples from your CF-card to a pad.

The card I have always been using is now also suddenly giving this message. I found an old SanDisk 16MB and a 1GB SanDisk that works perfectly in my Boss 864 and they also give the same message. Trying to go into formatting brings the message "no card!"
