I have this working quite well now. I'm using Prog chgs to control mixer
levels in AMS (8 x 2 mixer) In that way I can "stack" Reverb, Delay,
Chorus/Flange and some sort of vocoder / pitch shifter for harmony

I have all of the LADSPA plugs I can find; CMT, SWH, TAP, etc. It;s
seems any of the vocoder / pitch shifter plugs I try to use cause AMS to
segfault and crash. 

Any ideas why?
