Broken DX7 patches

[dpwe]

In listening through all the preset patches to identify excessively loud ones, I noticed a couple of the DX7 patches that seem broken:

• 158 (DX7 TRAIN) - really loud periodic noise bursts, although they decay away and sound almost deliberate.
• 230 (DX7 SYN-CLAV 3) - as you hold the note, it switches rapidly between a tone and noise bursts of varying loudness, some too loud. Not any SYN-CLAV I'm familiar with
