Here is an email thread between Dan and I below. From what Dan said, I take it as the new DMX adapter will support all the features. Now I understand, "it", the adapter, will only send what the software tells it. This will mean that the software will be able to generate this logic, fades, twinkles etc and send it as DMX output.
As far as the iDMX, they will only be truly useful if you have a current DC MP3 player, using older software, or a PC that is under powered.
"Dan,
Will the new DMX adapter support the full features for all 512 channels. i.e fades"
"Hi Jeff,
Yes the new adapter will support effects on all 512 DMX addresses.
Best regards,
