I have an expression 'heavy' patch I was hoping to convert via Heavy to Owl but it has fallen at the first due to the use of expr and expr~. I was wondering if anyone could help with the first few and then I could try and get my head round the others.

expr~ ($v1<.5)*$v1; ($v1>=.5)*$v1 splits waveform in two.

expr pow($f1, 1.0/3) power without pow?

expr~ $v1*((.5-$v2)/$v2);(-1*$v1+1)*((.5-$v2)/(1-$v2)) is totally beyond my little brain at the moment too!

None of this urgent or anything, just having fun.
