1 – Why not look into adding this type of pitch shifting? I don't understand why you will only work with existing algorithm's. If you look at Fractal Audio's support page, Cliff provides new algorithm's almost on a weekly basis, completely based on customer feedback. Why can't Eventide do this as well, instead of saying "stick to the available algorithm's"?
2. Why not consider supporting modeling? Why is this such a closed door with Eventide?
3. Tap tempo, set up via midi CC to an external, is NOT accurate using this method. The only accurate method of tap tempo is using the front button. This is CLEARLY not optimized for live performance, no?
