Linear FM Stretch Goal added!

15 likes

The most requested item not in the original design spec has been Linear FM. This requires a dedicated ADC on the 4 channels of the FM jack, as opposed to simply summing in the CV to the 1V/OCT voltage.

The design team has discussed this cost in both HW and DSP code, and it's impact on overall performance.

The answer is: YES! We can add this feature, as a menu option on the VCO Page. There will be 3 'depth' ranges: 100Hz, 1KHz and 10KHz. Since there is a hardware FM CV attenuator, the full range of possible depth is covered. THe FM CV can be an audio signal up to 15KHz.

The addition of Linear FM requires added HW and SW development. The goal is a total pledge of $115,000

      Great Stretch Goal! Very happy to see this feature will be added into the module. It's exciting to see this project growing already, and we are only a couple days in. The future is oh so bright for the E370.
