Re: [Csnd-dev] UDO problem in latest develop

This is how it's being used in context:

instr Drone
    idur = p3
    iamp = ampdb(p4) / 7
    ifreq = p5

    icps = ifreq / 4
    icps2 = icps * 1.5
    icps3 = icps * 2
    prints("drones: %f, %f, %f\n", icps, icps2, icps3)

    aenv = linen(iamp, 3, idur, 3)

    a1L, a1R = RissetHarmOsc(icps,  0.004, aenv, giPrime)
    a2L, a2R = RissetHarmOsc(icps2, 0.005, aenv, giPrime)
    a3L, a3R = RissetHarmOsc(icps3, 0.006, aenv, giPrime)
    ga_drone_L +=  a1L+a2L+a3L
    ga_drone_R +=  a1R+a2R+a3R

    printks("drone %f, %f\n", 2, ga_drone_L, ga_drone_R)
endin
