Zoom GFX-4 Looper/Sampler Jam

Hold Delay By selecting PP-DLY or ECHO as the effect type in the DELAY/REVERB module and setting parameter 2 to "Hd" or "Hs", a patch can use the hold delay function where the foot switches serve to control recording and playback of a phrase. ‘«‚ Select the above type of patch in manual mode and press foot switch 3 to start recording. ‘«‚ When foot switch 3 is released or the delay time set as parameter 1 has elapsed, recording terminates, and repeat playback of the recorded phrase starts automatically. ‘«‚ Pressing foot switch 3 during repeat playback stops playback.

There's also another cool function called "Seamless delay" which allows Delay to stay on even after switching patches! Seamless Delay (Patch delay) Using the seamless delay function causes the delay sound from the immediately preceding patch to be heard still after switching patches. The seamless delay function of the GFX-4 can be used when both the patches (before and after switching) fulfill all of the following conditions: (1) REV/DLY module = ON (2) REV/DLY module effect type = PP-DLY or ECHO (3) Delay time = Max. 1 second When both the patches (before and after switching) have the REV/DLY module ON and the FB/HLD parameter set to "HS", the hold delay function can be used as seamless delay. In this case, the recorded phrase continues to be repeated also after the GFX-4 is returned to program mode and the patch is switched during repeat playback. To force an end to the hold delay function after a patch change, set the unit to the bypass condition.
