Fix sample effects ... again

[Miika Alonen]

Not working:

Effects can also be applied to samples using run:

z1 "B K (B B) K", run: [{with_bpm: 120}],
use: {B: :bd_fat, K: { sample: :drum_snare_soft, run: [{with_fx: :echo}] }}

Or all of the samples:

z1 "B K (B B) K", run: [{with_bpm: 120}],
use: {B: :bd_fat, K: { sample: :drum_snare_soft },
run: [{with_fx: :echo}]}

Fixed ... again.
