Thanks. But I was looking for more technical info about the circuits. I noticed that they said the Strike Pro X Hat uses an FSR. Thought people had been down that road already and had issues. Wait, the Strike Pro HiHat does have issues! LOL!
I have a 100k slide coming some & micro switches. If the 100K slide doesn't splash then I'll use a slide switch combo. I started designing the housing for the parts that mounts to the base of the stand.
https://www.tinkercad.com/things/4EHl3I8kziOI'm printing one tonight to see how it fits. 10hr print. I know slide pots wear out, but they are only $2 to replace. Many people have used the Goedrum slide pot on the Strike Pro. It's 20K. The DM10 MKii Pro (NOT DM10 or DM10 MKii Studio) needs more than 50K or 50k and a switch to trigger a splash. Full open to close to full open rapidly is what triggers it. A switch could do this and reliable vs a slide pot only. No more missed closed / full open from a dirty slide pot. I think you can have some wiggle room for half open as to how far it's open.
Another way might be to use a soft pot with a roller wheel on the stand. same as using the Alesis pedal, but you get a real stand. Eh, maybe. Dirt issues.
Best I can think of so far is an encoder strip with light sensor plus an adrino. More complicated and requires some programming plus external power. But it would work ALL the time and perfect. I'll do this next if the simple pot doesn't work out.
