change matrix to reset internel sequencer on reset instead of too first pattern
fixed posh sampler pitch changing on reset.

this is also usefull in that it can give the ability for a Reset

to at any point completely kill audio and reset to begining(usefull
for recording takes where you want it to start at specific point w/out
