Fast Scan Matrix Example

I have completed the digital piano project in terms of my original needs. I have just added 2 midi channels so that I can split the keyboard. This additional work is partially coded.

However I want to play a Hammond Organ, DX7 and Prophet softsynth that I purchased a few years ago. I need to incorporate a organ type "swell" pedal into the system. This is just a volume control.

I will use the foot pedal to control the generation of the appropriate Midi CC.

The distance from the main board to the pedal is about 1 metre. My belief is that a digital solution would be better than an analog one.

I have no familiarity with faders or encoders. Are there "smooth" rotary switches? Are these method worth considering? Or are there other alternatives? I have a foot controlled pedal from an old organ that uses a potentiometer.

Thanks for your help.

Robin

Hi Robin,

Probably pedal -> analog potentiometer -> ain -> core -> midi is the way to go...

Methinks that there are no encoders offering the resolution you need (128 steps for the full pedal travel).

Best regards,

Peter

Hi Robin,

I agree with Peter.

If you are using a potentiometer with lower resistance (1k is the ideal value in your case), and connect it to the core via a shielded cable, it should work without jitter.

Best Regards, Thorsten.
