Now look at that,

your hints are much appreciated, fellas.

I exchanged midiyoke for midi maple and omb now talks to Hypersonic like to an old friend. Thank you, Bluesplayer!
Now some things I canīt get my head around in hypersonic 2 an OMB:
1. psr-styles usually have drums set on channel 10 and percussion on channel 9, if my memory serves me right. When I look at the OMB-Mixer, there are several tracks with drumvoices (percussion as well) set to channel 10. Thats strange. Why is OMB sending its stuff in a different way than an yammie arranger does? Hypersonic definitely receives no mididata on channel 9 when it receives a psr-style - strange.
2. It seems, the GM drum is the only one of all the drum kits that has the the percussion instruments (conga, bongo etc.) included. When you change the GM kit to another kit, the percussion is missing. Why is that? (In sonicsynth you could do so - load different non-GM-drums instead of the GMs, and it still sounded good and made a nice change to tweak a style). How can different drums in HS be used to overcome this and have the percussion played like in the GM-Kit?
3. When playing psr styles from OMB to Hypersonic 2 (in GM-Mode), the volumes of the channels have to be tweaked a lot and some sounds are not correct at all. Lots of fiddling... Are there any premade patches (XG, sweet voices etc.) that fit better to a - say tyros 2-style - than the GM-settings ion Hypersonic?

Iīm coming a long way, but I guess others will be interested in this as well.

Best regards to all
