expon traces an exponential curve between two points whose 'time-distance' can be given.
kr expon ia, idur1, ib ar expon ia, idur1, ib
ia: starting value
ib: value after idur1 seconds The following example shows a signal (of length 1 second) that decreases 50% (0.5*iamp) every 250 ms (ilen*0.25) sr = 44100 kr = 4410 nchnls = 1 instr 1 ilen = p3 iamp = p4 as expon iamp, ilen*.25, 0.5*iamp out as endin i1 0 1 25000 Instruments
