MisterEd,
About your two questions, there is insufficient information so I cannot answer to your satisfaction:
1. Can you elaborate a bit more as to which sites you see the wave samples? Different wave samples may act differently in your PSR9000. If you do not record samples for yourself, the best wave samples to look at are those customized for PSR9000 so you do not have to worry sample loop point ... etc. PSR9000 allows wave recording of up to 32 MB but I have not tried loading wave samples with 32 MB or more in size to the sampling SIMMs - so I cannot confirm whether PSR9000 can load wave file larger than 32 MB, I speculate that the limit per wave file for loading is also 32 MB. How many samples can you load into 65 MB of SIMMs depends on the size of the wave files and how many of these you use for the range of keys you define per custom voice. The more samples you use per custom voice, the less number of custom sounds you can use. That is why you need a hard disk to store different wave sample files. For the 8 GB of hard disk space that PSR9000 can recognize, I use the first 2 GB partition just for styles, the second 2 GB partition just for songs, the third 2 GB partition just for wave sample files, the last 2 GB partition for miscellaneous system backups, exported factory and flash styles, mainly used as scratchpad for development before moving the final products to the other 3 partitions.
2. For the front mic/line input jack there is a three-position switch (mic1, mic2 and line) to set for impedance matching, and use the round knob below the switch for input level adjustment depending on how hot the input signals are. You can connect external sound source through the input jacks at the back of the PSR9000 but the sounds will not be processes by PSR9000's internal harmonizer and effects. Using the front mic/line input you can press the rightmost column of buttons for vocal harmony effects (especially the DSP(8) and VH buttons) for effects setup. You can also hit the third button in the digital studio section to access the Mixing Console for effects fine tuning for microphone/line sounds (at the very bottom row of the parts setting page). You can experiment different settings and the key is to get hot enough signals without distortion.
