Hi Sev01,
I have been able to create some custom styles from scratch and they seem to work ok ... just need some minor volume adjustments when I done.
I also sampled with the sampler and edited existing samples in order to syncapate the wave file(s) with the arranger and some midifiles and these worked ok (within certain tempo ranges).
Send me an email with your specific issue(s) and steps to create them and we can see if it's a 'slip' or a defective SD1!
Thanks.
AJ
