Problem with AudioDelayFeedback Example Sketch about mozzi HOT 4 CLOSED

So i want to learn the basic form of delay. Using the AudioDelayFeedback example i would like to create a sketch that only reproduce the signal delayed after release the button. When i press the button, i want only signal in my ear. If i try to use the delay only option in the output part of the code, i recive an error. The error is: testdelay:57:47: error: call of overloaded 'next(int8_t, byte&)' is ambiguous return aDel.next(aTriangle.next(), del_samps); // instead of the previous 2 lines for only the delayed signal ^ In file included from C:\Users\User\Documents\Arduino\testdelay\testdelay.ino:18:0: C:\Users\User\Documents\Arduino\libraries\Mozzi-master/AudioDelayFeedback.h:92:10: note: candidate: int16_t AudioDelayFeedback<NUM_BUFFER_SAMPLES, INTERP_TYPE>::next(int8_t, uint16_t) [with unsigned int NUM_BUFFER_SAMPLES = 128u; signed char INTERP_TYPE = 0; int16_t = int; int8_t = signed char; uint16_t = unsigned int] int16_t next(int8_t input, uint16_t delaytime_cells) ^ C:\Users\User\Documents\Arduino\libraries\Mozzi-master/AudioDelayFeedback.h:117:10: note: candidate: int16_t AudioDelayFeedback<NUM_BUFFER_SAMPLES, INTERP_TYPE>::next(int8_t, Q16n16) [with unsigned int NUM_BUFFER_SAMPLES = 128u; signed char INTERP_TYPE = 0; int16_t = int; int8_t = signed char; Q16n16 = long unsigned int] int16_t next(int8_t input, Q16n16 delaytime_cells) ^ exit status 1 call of overloaded 'next(int8_t, byte&)' is ambiguous My code is: /* Example of flanging, using Mozzi sonification library.
