A Karplus-Strong UGen
| in |
an excitation signal. |
| trig |
upon a negative to positive transition, n samples of the excitation signal will be fed into the delay line, where n = delaytime * sample_rate / 2, using a rectangular envelope (no fading). |
| maxdelaytime |
the max delay time in seconds (initializes the internal delay buffer). |
| delaytime |
delay time in seconds. |
| decaytime |
time for the echoes to decay by 60 decibels. Negative times emphasize odd partials. |
| coef |
the coef of the internal OnePole filter. Values should be between -1 and +1 (larger values will be unstable... so be careful!). |
| mul | |
