2 quick requests:  
#1 - Firstly, this is yet another sincere request to integrate a transparent mode for tap tempo; specifically on Tape & Analog-style delays. This is industry standard for most delay effects _(ex: TC Electronics ND-1 Nova, Boss DD-20, Strymon El Cap & Timeline, Eventide Timefactor, and more recently the GFI Solis Ventus…)_ In a live setting, the Quad Cortex audibly produces extreme warping sounds when switching BPMs. This is blatantly noticeable and prevents musicians from syncing a delay to the song-specific BPM in real time. PLEASE fix this.

#2 - From my extensive experimentation with the “MicroPitch” module, the integrated delay does not sync to Tap Tempo whatsoever, even when the time signature parameter (ie; 1/8, 1/4, etc) is disabled and the “sync” mode is on. That is still an issue on latest firmware 3.3.1.

Thank you,

I see that you voted on this request thread but I’m adding it for the benefit of others:

> After using the QC live, I’ve had several instances where have to tap tempo in the middle of a song. This results in natural pitch fluctuations inherent when changing the time setting on a delay. On the helix and other digital delay pedals, there is an option for “transparent” tempo, which shifts without causing these artifacts and fluctuations. This should be a setting where users can opt to have this apply or not.

I’m away from my QC at the moment, so I can’t confirm the tap tempo issue with the MicroPitch block. But it would be good to log a bug report for that.
