Hi Aaron,
I have reduced the "internal sample rate" inside PianoTeq's Options->Perf

dialog and it helped a lot according performance. I can choose e.g. 29400 Hz

or 22050 Hz there and I can not really hear the difference in sound quality

(maybe my old ears?!). 
By that I can play PianoTeq and B4 Organ at the same time with no problems on

my LG X120 (Atom CPU N270 @ 1.6 GHz) through Jack. (To be honest, I'm

using -p128 as buffer size)
Gerhard
